Sweet sweet corn cultivation technology

Everyone knows about corn, and there is no person who would not love it in one form or another. Fresh, boiled, frozen, canned grains, corn porridge, and other types of healthy and tasty cereals.
The sugar corn variety has found its admirers all over the world. Many gardeners are happy to grow it on their own.

Description and characteristics

This is an annual cereal, quite patiently related to a difficult climate, different soils, and undemanding to care, a tall plant from one and a half to three meters. Differs in the presence of male and female flowers on one stem. The root of corn reaches a length of more than one meter, has a very strong structure, fibrous.

It is a high-yield cereal rich in oils, carbohydrates and proteins that are easily absorbed by the human body.

Vitamins of group B, PP, C, carotene, as well as tryptophan and lysine, contribute to the rapid absorption of trace elements and the breakdown of carbohydrates.

Ripe ears usually reach 16 - 25 cm, have a dense structure, bright yellow seeds, tightly adjacent to each other. The taste is delicate and sweet, milky.

How sweet corn differs from regular corn

It is impossible to distinguish the seeds of regular feed corn from sugar corn unless you have similar experience. But, the seeds still have external differences:

  • Fodder corn seeds are darker;
  • Sugar varieties are somewhat smaller;
  • When boiled, sugar varieties swell faster and become tender;
  • Even dry seeds, when bitten through, are sweeter in sweet corn.

Corn on the cob can be distinguished by the following characteristics:

  • The ear is more rounded, barrel-shaped, with a blunt end;
  • The grains are lighter, milky,
  • If you crush a grain between your fingers, it practically bursts;
  • Even not thermally processed, tastes sweeter, and fodder is difficult to bite;
  • When cooking, it is ready in 10 minutes, and the feed will be very tough in half an hour.

Overripe sugar grains are much darker than young ones and therefore can be considered fodder. The most correct test is "on the tooth".

Sweet corn is healthier and tastier than conventional forage varieties. The complex of minerals and light sugars is ideally balanced in it. The low level of starch allows you to feast on it even on a diet.
Fodder varieties are tasteless, require prolonged heat treatment, and have very tough grains.

The best varieties

There are over 500 sugar varieties, and everyone will surely find the best one for themselves.
Important: The early varieties are suitable for more severe climates, since they have time to ripen before the cold weather, and the later ones for the southern latitudes are the most productive.


An early maturing variety, famous for its taste. Delicate grains, milky sweetness. Very fast and friendly seed germination, low maintenance. You can plant seedlings or seeds as soon as a stable temperature above 10 degrees is established.
The plant is up to 170 cm high, 70 days after sowing, the grains are filled with maturity and are ready for use.


One of the varieties most beloved by gardeners. Up to 2 meters high, with 20 centimeter cobs, very sweet and juicy grains. Ideal both for boiled consumption and for preservation.
Seeds are sown in April, and in May they are already planted in the ground. Reaches full ripeness in 2 months.

Ice nectar

Late-ripening super-sugar grade. It reaches a height of 2.5 m. It is thermophilic, picky about watering and soil. Afraid of sudden changes in temperature. Maturity occurs between 80 and 90 days. Suitable for all types of use.

Gourmet 121

One of the earliest, high-yield sugar varieties. After 70 days, it gives a friendly harvest of grains of milk ripeness. Rich in flavor and disease resistance.
It is thermophilic during the seedling period, but under the condition of hardening the sprouts, it quickly adapts.

Landing rules

Observing simple conditions, gardeners and farmers receive a rich harvest. It is important to consider several principles:

  1. Prepare the soil in the fall before frost - dig thoroughly, remove weeds.
  2. When planting seeds in open ground, you should not do this earlier than mid-May. Seedlings should not appear at temperatures below 10 degrees.
  3. When planting seedlings, in April, you need to prepare the seeds: put them on the sunny side for one day on a windowsill or in a greenhouse, then hold them in cool water for about an hour and rinse.
  4. Seeds are planted in separate pots, 2 pcs. Moisten the soil well, cover with a transparent film until shoots appear.

Cultivation and care technology

The cultivation technology is almost the same as for conventional varieties. When the first shoots appear:

  • it is necessary to loosen the soil after each watering;
  • prevent the soil from drying out;
  • weed weeds;
  • monitor the appearance of painful plants and remove them in a timely manner.

Important: in the process of forming the cob, you need to carefully consider watering, since the size of the cob and the sweetness of the grains directly depends on the quality of watering.
Top dressing:

  1. After the appearance of the first five leaves, it is necessary to fertilize with potash fertilizers;
  2. If the leaves have a light shade, turn yellow a little, add nitrogen fertilizers when watering;
  3. If the edges of the leaves look scorched, the plant is clearly deficient in potassium.

Re-feeding should be carried out not earlier than the beginning of the formation of the peduncle.

Diseases and pests

The most common diseases are:


Fungal disease. It appears most often during a period of excess moisture and affects already ripe ears. The grains acquire a light bloom and begin to rot. It is important to check the crop and remove diseased plants.... After harvest, they are burned.

Stem rot

During the growth period, dark spots are found on the lower part of the stem. The ear is also affected, the growth of the plant slows down. Only burning diseased plants will help. In the fall, it is necessary to burn all the leaves and stems, change the planting site the next year, or pickle with fungicides.

Corn rust

Bright red spots on green leaves on the underside. A fungal disease in which spores form on the leaves. For prevention, seedlings are treated with furingicide

Sugar maize is an excellent grain. Its benefits are undeniable, and if you decide to grow it yourself on your land, choose varieties based on the location of the site, your priorities and wishes. And on your table all year round will be these sweet golden grains in any form.

It is sweet corn, a tall (up to 3 m) annual herbaceous subtropical plant with a well-developed root system. The stem of this plant can be up to 7 cm in diameter. The female flowers of sweet corn are collected on the cob, the male flowers are gathered in panicles. The fruit is a reniform or round caryopsis. It may have a different color, depending on the variety. The most commonly grown varieties are with yellow ears.

It differs from fodder sweet corn in more delicate leaves and lower height. The ears develop faster on it. Flowering can begin when the plants reach a height of 20-25 cm.

Growing corn as a business

Things to consider when starting to grow corn as a business:

  1. Choose a high-yielding hybrid in our online store.
  2. To carry out high-quality tillage.
  3. Have modern agricultural machines and implements - corn seeder, multicultivator.
  4. Perform timely care - loosening the soil (harrowing), removing or breaking through seedlings, hilling stems, feeding.
  5. Use effective herbicides
  6. Protect from insect pests: spray plants and soil.
  7. During flowering, additionally pollinate.

Growing corn at home

Despite the widespread professional cultivation of corn, that is, growing corn as a business, the cultivation of corn seeds at home is also relevant. It is necessary to take into account the agro-climatic conditions of the summer cottage and adhere to some rules. And you can buy seeds of corn hybrids from us.

What do you need to plant sugar corn seeds in your area?

  • high yielding hybrid
  • fertile, slightly acidic ground
  • warm, wind-protected place
  • plant corn seeds not in rows (this contributes to pollination of female flowers), but in rectangles - get a higher yield
  • fertilizing with mineral fertilizers during the growing season
  • artificial pollination - lightly shake the panicles in the morning: pollen from one corn will fly to another, as a result large cobs and grains will form on them.

Sugar corn seeds grow well next to cucumbers, tomatoes, pumpkins, beans and beans. Do not plant corn next to celery or beets. Farmers on small plots often practice the proximity of corn and cucumber. The harvest of both crops will delight you!

Sowing corn should be started in late April or early May in well-dug soil. Corn seeds are applied 8 cm deep into the soil, in a square-nesting method (60x60) or in a wide-row method, row from row is placed at 60-70 cm.Under suitable conditions, seedlings appear in 7-10 days. Then you need to loosen between the rows and between the plants. When the second leaf appears on the corn, the planting must be thinned out. When removing, leave sprouts in the row at a distance of 35-40 cm. If you sowed corn in the holes, then leave two sprouts. Then sometimes loosen the soil, especially after rain, remove weeds.

If you have chosen sugar corn seeds that you want to grow in the field or in your country house, take care of the required amount of seeds. Our online store offers you not only wholesale, but also small packaging of corn seeds.

Conditions for growing corn

The optimal soils for sugar corn are deep sandy loamy podzolized loamy light and chestnut chernozems. When growing sugar corn, it is not recommended to use soils that are poorly drained, waterlogged, or understated. Loamy and saline type soils are not suitable. The acidity of the soil should be very low, but if the pH drops to five, then the plants get sick and die.

Despite its good tolerance to hot weather conditions, sweet corn does not tolerate droughts. If we compare this category of plants with grain varieties, then sweet corn requires much more moisture. Most of the moisture in the soil is needed by plants during the period of fruit formation, which begins seven days before the formation of a panicle and lasts about 30 days. If the soil is not moist enough, the upper parts of the ear cannot form grains, or they grow weak and small. Once the cobs have grown to the correct size and shape, the need for watering drops slightly.

The birthplace of corn is Central America. Scientists have discovered some parts of the corn in Mexico, in the caves of the Indians. The finds date back to the third millennium BC. About 400 years ago, corn appeared in the European part of the world. Our country started growing corn in the 17th century. Sugar corn began its history in 1799, when the first mentions of it were found in historical documents. By the middle of the 19th century, 12 varieties of sugar corn appeared. Today, at least 80 countries of the world are engaged in the construction of this crop, more than 400 thousand hectares of land are occupied with corn crops. The leaders in sugar corn production are the Caribbean, the United States, Mexico and Canada.

It is worth recalling that sweet corn is a gourmet type of vegetables. Due to its qualities, taste and nutritional value, in terms of the level of vitamins and useful elements contained in sugar corn, it has rightfully taken one of the first places among other vegetables. It is consumed on the cob, boiled, canned, frozen and dried. During the period of wax-milk maturity, grains contain up to a third of dry matter, carbohydrates make up a quarter of the composition, a tenth is dextrins and about 4% is dry protein. The proteins of sugar corn are more nutritious than those of other species. They contain a large number of these amino acids, most of which consist of lysine and tryptophan. Due to its high dextrin content, corn has a high taste. Grains contain B vitamins, calcium, potassium, phosphorus, nicotinic and pantothenic acids, biotin and choline. Varieties with yellow grains have carotene - up to a milligram per hundred grams, and vitamin E. Grains with a volume of 0.1 kilograms contain 03, milligrams of sodium, about 300 milligrams of potassium, from 50 milligrams of magnesium to 20 milligrams of calcium, about 100 milligrams of phosphorus and 0.5 milligrams of iron. In addition, grains contain a lot of iodine, chlorine, sulfur and some other elements.

The rich chemical composition of sugar corn allows its extensive use for medical purposes. Scientists have proven that areas where there is a large amount of corn and rice, people are much less likely to get atherosclerosis. Corn oil, which is produced from grain in its embryonic state, contains a large amount of active biological substances. This product has a beneficial effect on the condition of the blood by lowering cholesterol. Doctors who are prone to the formation of atherosclerotic plaques are advised to eat up to 35 grams of corn oil per day. Corn stigma is used to treat inflammation of the liver, gallbladder, and urinary-reproductive system. Extracts of corn silk are diuretics, hemostatic agents. Grains of sugar corn are used to obtain glutamic acid, which is used to treat diseases of the children's central nervous system.

In Ukraine, sugar corn has been steadily gaining popularity over the past few years. Yet this culture is not yet very widespread. Statistics say that 2009 was marked by the sowing of only 6,000 hectares of sweet corn. Taking into account the average annual consumption of sugar corn in the amount of 3.7 kilograms per person, an area of ​​at least 25 thousand hectares should be allotted for this crop, and this is only for internal needs. Thus, the bulk of processed sugar corn is imported into the country.

Crop rotation and variety composition

It is most correct to use fields for planting sugar maize from winter cereals, legumes, fodder beets, potatoes, melons, tomatoes, cucumbers, zucchini, squash, onions, root crops and vegetable beans. It is not recommended to plant sugar corn in fields where millet or cabbage plants were previously grown. If organic and nutritious elements are introduced into the chernozem in a timely manner and in the required quantities, then sugar corn can be grown in one place for two years in a row. Experts advise in no case to plant sugar corn next to dent-like and flint varieties, the plants can become over-pollinated, which will lead to a decrease in the amount of sugar in the grain. The different categories of corn should be planted at least one kilometer apart.

Most varieties and hybrids of sweet corn are subdivided into early-maturing, mid-maturing and late-maturing. In the "State Register of Plant Varieties Suitable for Distribution in Ukraine" at the moment, 2 dozen varieties and 25 species of hybrids of this culture are registered.According to scientists, as well as vegetable growers, hybrids are distinguished by higher yields and better quality grain than varietal ones.

Seedling and non-seedling growing methods

Sugar corn is grown without seedling and seedling methods. The method of planting seedlings is considered to be quite expensive and rather laborious, however, it is this method, subject to all technological features, that brings the greatest profit, because the finished, marketable product is received two to three weeks earlier. To achieve the maximum effectiveness of this method, experts recommend using sprouts that are 20 days old. At a time when the topsoil has warmed up to 15 degrees at a depth of more than 10 centimeters, the seedlings are placed in an open field. If you also use covering materials with this method, then the landing time can be reduced by another week. Do not forget about soil moisture, the soil must be thoroughly moistened. After the plants have been planted, they are checked after a couple of days, the dead shoots are removed and watered again. The next watering should be no earlier than a week later, this will enable the root system of the plants to take root. The best time for planting seedlings is the evening and preferably cloudy weather.

The most popular sowing method is by seed. This method assumes the only mandatory item - the preparation of seeds for sowing. Do not ignore the advice on preventive seed treatment, this prevents the formation of diseases such as stem rot, smut, fusarium and others. To be able to collect the cobs of the wax-milk degree of maturity continuously, it is necessary to sow sugar corn over a period of 1.5-2.5 months at several times, every two weeks. This sowing method will help to start harvesting in the second decade of July. Forest-steppe regions can start sowing in late April - early May, in the south of the country they begin sowing in early-mid April, Polesie begins sowing by mid-May.

When using a drip irrigation system, the following sowing systems will be the most optimal: early, low varieties - wide rows, 70 by 25 centimeters or 60 by 30 centimeters, late varieties - a nesting scheme of 70 by 70 centimeters, after the crops are thinned out, in each no more than two plants should remain in the nest. These schemes assume from 40 to 57 thousand plants per hectare. In heavy soils, seeds need to be immersed 3-4 centimeters, in light ones - up to 7 centimeters deep. In this case, the number of seeds will be from 15 to 25 kilograms per hectare.

In order for the drip irrigation system to be used as fully as possible, experts advise laying the irrigation system at the same time as sowing seeds. It is best to lay the tapes to a depth of about 3 centimeters. Thus, one irrigation branch, equipped with outlets at a distance of 20-30 centimeters, is capable of well moistening one sowing row. When sowing is complete and the irrigation system is laid down, it is necessary to water it. In cases where sugar corn is grown by the seedling method, the irrigation system should be laid in advance and the soil should be moistened in advance.

Before doing growing corn in the open field, it is important to choose the right variety. The main types of this plant include the following varieties:

  • Puffed corn is the same corn used to make popcorn. She, in turn, is subdivided into rice, pearl and pearl barley. This type includes the varieties Miracle Bump, Red Arrow, Zeya, Vnuchkina Joy, Volcano.
  • Toothed - it is most often grown in order to boil or freeze. These varieties are used to make flour, cereals, alcohol and silage. These are tall, up to two meters, plants that yield up to 150 c / ha of yield, however, most varieties are medium late. This species includes the varieties Ruby Garnet, Indian Giant and Blue Jade.
  • Siliceous - this type is not often grown, since farmers are not attracted by low yields - only 70 c / ha. Meanwhile, the varieties of this plant survive frost well and are resistant to shedding, without being exposed to dangerous diseases. These plants are often used for the production of cereals, cereals and animal feed. The species is represented by the varieties Cherokee Blue, Mays Ornamental Congo.
  • Wax - grains differ in that they contain only amylopectin, while other varieties also contain amylose. Thanks to this, such corn can be eaten by people with diabetes mellitus, since it is absorbed more slowly by the body, without raising blood sugar levels to critical levels. This species includes the Early Pink Radiance (a very early variety) and is often referred to as White Dakota and Black Waxy Maize.
  • Sugar corn - growing these plants are possible both for conservation and for freezing, and at the same time they are considered delicacies. Such varieties include Honey Nectar, Divine Paper of 1822, and Bloody Butcher. These are early maturing varieties, rather large in height, with medium-sized ears (up to 19 cm).
  • White - has special growing requirements, therefore it is better to place them only in well-lit areas. The varieties include the Little Mermaid, Snow White, and the Snow Queen.

Growing and caring for corn require certain knowledge, because very often these plants are quite whimsical to the environmental conditions.

Growing soil

Growing corn in the country should start, as always, with the choice of the soil composition. It should be clean, loose and breathable. It is desirable that the humus layer is deep enough and has a pH of 5.5-7. Chestnut, dark gray loamy and sandy loam, as well as floodplain soil are suitable. Growing corn in a greenhouse should follow the same rules, and it is important for the farmer to correctly adjust the acidity of the soil in this case.

Growing corn for grain also requires correct predecessors, which include winter crops, tomatoes, melons, potatoes with beets, and legumes.

Conditions for growing corn should be like this: choose a well-lit warm place, and pre-fertilize the soil with rotted manure or phosphorus-potassium dressings.

Corn care

Maize cultivation technology should be as follows:

  • Sow the plant in rows between rows should be about 60 cm, between plants - 40 cm.
  • Planting begins at the end of April
  • The day before sowing, nitrogen fertilization can be applied, and the seeds are pre-heated for 5 days at a temperature of +35 degrees.
  • Before planting, loosen the soil 10 cm
  • Seeds should be planted to a depth of 7 cm, the soil should warm up to +12 degrees.

The cultivation of bonduelle corn, like other varieties, requires special care. At first, you need to regularly weed and loosen the soil between the rows. You can also manually pollinate the plantings - for this, pick a male flower (you can recognize it by the sultan at the top of the stem) and shake it over those cobs that have already bloomed. Remove stepchildren in time and also avoid over-watering.

As for fertilization, this plant prefers feeding from mullein, compost and humus. You can also add superphosphates, potassium supplements and ammonium nitrate in liquid form.

The use of maize plant protection products depends on the phytosanitary state of the soil and crops of each individual year. However, it is always necessary to pay attention to the main (most negatively affecting the yield) corn pests, diseases and weeds. Pest and disease monitoring is an essential step in the crop protection cycle.
At the beginning of development, corn grows slowly, so weed protection must be carried out. To destroy weeds, destroy the crust and retain moisture, no later than 3-5 days before the emergence of seedlings on corn crops, you need to harrow in one or two tracks. Harrow with light or medium harrows. This also enhances air access to the root system and contributes to the emergence of more friendly seedlings. Another harrowing is carried out in the phase of 3-4 leaves across the rows. It is better to harrow crops in the afternoon, when the plants lose their turgor, and reduces plant injury.

Sweet corn - growing: from planting to leaving

"Hot Sweet Corn!" Who has not heard these words in the summer, on the beach, from the annoying sellers of a seasonal product. What kind of corn is it and how does it differ from other types?

Sweet corn: description and useful properties

Corn came to Europe from America, its southern and central regions. Fodder came to us in the 17th century, and sugar - a couple of centuries later. But sweet corn became widespread several decades ago.

It is usually eaten boiled when the seeds are just forming and growing, but not yet hard. This condition is called milky-wax ripeness.

It can be frozen or canned and used in salads during the winter.

  • Sweet corn fruits contain a large amount of proteins, starch and dextrin, fats, sugar, and mineral salts.
  • This plant is valued for the content of a large amount of vitamins of groups of main groups, amino acids (lysine, tryptophan).
  • Corn oil is made from corn seeds, corn silk extract, which, moreover, are medicinal products.

  • Sugar corn (maize) is an annual plant reaching a height of 2.5 m.
  • Its fibrous roots penetrate deep into the ground up to one and a half meters.
  • The leaves are long (up to a meter), wide (up to 10 cm), linear-lanceolate, dark green.
  • The stem can be up to 7 cm thick.
  • Corn has two types of flowers: male, located on the apical panicles, and female, collected on the cob, growing from the axils of the leaves.

One or two ears are formed on one plant. If more of them are tied, then they will not have time to ripen. The length of each ear depends on the variety and growing conditions. The length ranges from 4 to 50 cm, the width is from 2 to 10 cm.

The mass of a ripe ear is from 30 to 500 g. It is densely surrounded by leafy wrappers. A bunch of pistils emerge from them. The pollen from male flowers is shaken off by the wind and falls on the pistils. Caryopsis are formed, which tightly fit the ear.

The color of the caryopses is yellow, reddish, white and even black.

There are very beautiful varieties, the kernels of one cob are painted simultaneously in yellow, pink, blue, purple colors and their shades.

It is believed that corn is the oldest cereal plant in the world. Corn differs from other cereals in that it is not hollow inside. There are 9 botanical groups of corn, one of which is sugar corn.

Popular varieties of cereals

Varieties for warm regions:

  • Kuban canning-148
  • Zarya-123
  • Fragrant
  • Early golden
  • Sugar-590
  • Accord-72 (hybrid)

Varieties for the middle lane and the Urals:

  • Pioneer of the North
  • Tiraspolskaya-33
  • White Night
  • Triple sweetness

Growing sweet corn

Sweet corn, like other species, is a heat-loving plant. Its seeds germinate at a temperature of 8-13 degrees. A sinking during germination often results in seedlings not appearing on the surface. The optimum temperature is considered to be 20-24 degrees. Grows poorly in the shade.

The best precursors for sweet corn are beans, tomatoes, cabbage, melons, and root crops. The plot begins to prepare immediately after harvesting the predecessor:

  • Add 3 kg of humus, 30 g of superphosphate and 10 g of potassium salt per 1 m2.
  • If the soil is acidic, it is advisable to carry out liming before planting, adding 500 g of lime per square meter of area.
  • They plow the land to a depth of 30 cm.

Seed preparation and planting:

  • The seeds are taken large, from the middle part of the cob. Warm up for a week at a temperature of 35 degrees. You can germinate seeds, but only if they are sown in warm and moist soil.
  • Seeds are sown to a depth of 5-8 cm.The distance between plants in rows is 35 cm, between rows is 70 cm.
  • If the soil is dry and the area allocated for corn is small, it is a good idea to water each hole, wait for the water to absorb, drop the seeds and cover them with damp earth.
  • Sprinkle dry on top to better retain moisture.

In places of risky farming (middle lane), it is better to sow seeds in varying degrees of readiness: dry, swollen, sprouted. If the sprouted ones are sunk and do not sprout, then the dry ones will germinate later. Of course, sowing seeds from three jars into one hole is not very easy. And if they all germinate, then the weak will need to be removed along with the roots.

To feast on young corn for as long as possible, the seeds are sown in several stages with a difference of two weeks.

In the northern regions, where corn may not reach the state of milky-wax ripeness, it is grown as seedlings. Seeds are sown from mid-May in peat pots. Seedlings are hardened by taking them outside for a while. Planted in the garden 20 days after germination. After planting, watered using about 1 liter of water.

After the emergence of the majority of seedlings (10-12 days), the aisles are loosened to a depth of 7 cm, removing weeds. When they have 4 leaves, one sprout, the strongest, is left in the hole.

  • In the phase of 6 leaves, the plants are fertilized by adding 100 g of superphosphate, 50 g of potassium salt and ammonium nitrate per 10 square meters of area. It is better to mix these fertilizers, dissolve in water and pour the resulting mixture along the grooves made along the rows at a distance of 20 cm from the plants.
  • When the plants reach a height of 50-70 cm, they are huddled. This stimulates the formation of adventitious roots. They help the plant to get more nutrients and moisture from the soil. They increase the plant's resistance to wind gusts that can turn it out of the ground.
  • Watered 4 times per season. After each watering, the soil is loosened.
  • During the season, corn is loosened several times. This is usually done after rain. After it reaches a meter in height, it will not be easy to do this.
  • Stepchildren are constantly removed, which reduce the yield of corn and delay the ripening of the main ears.
  • When the corn is in bloom, you can help pollinate it. To do this, at noon, the plants are shaken so that the pollen flies more actively from the apical panicles.

To get ripe seeds for planting next year, take the cobs that ripen the earliest.

If they do not have time to ripen before the onset of frost, experts advise to uproot the plant and hide it in a shed. The wrapping leaves are removed in the spring. It is better to store seeds on the cob.

They are hung, tied with extreme wrapping sheets. So they are better stored and remain germinating longer.

Harvest by examining each ear. Ready-to-eat pluck. They should be at the stage of milky-wax ripeness, sufficiently formed, but soft. You need to consume them as quickly as possible. Indeed, in just one day, the amount of sugar in grains will decrease by a quarter. The crop is harvested every other day.

Diseases and pests of corn

Sweet corn is quite resistant to pests and diseases. But still, some stems can not only be affected by them, but also die from their impact. Sometimes the stem, leaves look healthy, and the ears are not set. Therefore, when doing weeding or other maintenance operations for sweet corn, carefully inspect the parts of the plants.

Major diseases of maize:

  • Dust smut is a fungal disease in which the panicle becomes covered with black spores, which fly around at the slightest movement. The ears of the affected plant are completely unusable.They are removed, the soil is dug deeply. For prevention, the soil is treated with Ditox, Granivit.
  • Fusarium blight appears as a pink bloom on germinating seeds or ears (Fusarium on the cob). The disease can go unnoticed, but the quality of the seeds drops sharply. They become soft and not recyclable. They grow resistant seeds treated with Granivit, Vitavax 200.
  • Bubble smut affects the entire plant. It is covered with gray swollen spots up to 15 cm in size. For prevention, they disinfect the soil, use crop rotation, treat with Ditox, Vitavax.

The main pests of sweet corn, like other species, are:

  • Caterpillars, which settle in the leaf funnel and begin to actively reproduce, testify to the defeat of corn by the stem moth. In the process of growth, the caterpillars of the stem moths cause significant damage to the plant. You need to fight by treating the area with insecticides twice (Decis and others). First, this is done as soon as the caterpillars have appeared, the second - when there are a lot of them. Seeds are disinfected with Gaucho.
  • Root aphids attack the plant in hot weather. Plants become weak, grow slowly, are affected by fungal diseases, and may even die. You need to fight by spraying with insecticides, often changing drugs. After all, aphids quickly get used to them and stop responding.
  • Cotton scoops damage pistil filaments. Large rounded holes appear in the upper leaves, and remnants of caterpillar vital activity appear inside the cob. They are treated with Decis.
  • Swedish flies begin to damage seedlings shortly after they emerge. Holes appear on the leaves and stems, the plants get sick. They are treated with Karate, Sumi-alpha, Decis preparations.
  • Wireworms attack corn that grows in newly plowed hayfields or virgin lands. They gnaw through the seeds before the seedlings emerge on the surface. To avoid damage, seeds are treated with Gaucho, Cosmos preparations.
