Spider mite control measures, types of mites, causes of occurrence, treatment against mites


Houseplants

It would seem that flower growers who have been breeding plants for several years know everything about pest protection, and try to take preventive measures to ensure that these same pests do not start. But despite the fact that we create the conditions necessary for the plants, water and spray correctly, fertilize and transplant, as required by agricultural technology, all the same from time to time our green pets get sick. It's just that there are pests that can appear even with careful and constant care, and spider mites are just such.
In fact, there are a great many varieties of ticks in nature, and, oddly enough, some of them are absolutely necessary. For example, soil mites are needed to maintain decomposition processes in the soil and form a nutrient medium.

Types of ticks

But today we will talk about harmful spider mites, of which there are also several species, and all of them are dangerous to plants.

Ticks are small, up to 1 mm in size (up to a maximum of 2 mm), sucking arachnids arthropods. They come in clear, milky, yellow, red or orange colors.

Like all ticks, the spider mite is a sucking arachnid. Their harmfulness is that they, feeding on plant juices, deprive him of strength. The first signs of the appearance of ticks are small light dots on the surface of the leaves - traces of punctures.

The red spider mite is more common than others. It is this pest that starts in my favorite balsams when I take them outdoors in the summer. No matter how I struggled with this scourge, all the same, by the end of summer, just after a period of intense heat, the leaves begin to overgrow with cobwebs - this is the work of ticks. The web is a product of their vital activity, but it is not dangerous for the plant. The main trouble is the tick itself, it, like a vampire, sucks out the juices of a flower.

Among the ticks dangerous to plants, in addition to the common spider mite, there is the Atlantic spider mite. If you are breeding exotic flower species, then you can get acquainted with flat mites. They especially love cacti, different types of citrus and ficuses, euonymus, but they do not disdain simpler flowers.

And the most insidious of the sucking pests, I would call root and bulb mites, damaging the underground parts of flowers. More precisely, they are destroying, since it is almost impossible to notice this microscopic insect underground in time, and as a result, when you dig it, you get a eaten onion or rags instead of roots.

Reasons for the appearance

We all take care of our flowers, protect them, but sometimes conditions arise that contribute to the appearance of a spider mite. For example, if the air in the room is dry and warm, but in apartments with central heating it is exactly like that in winter. Solution: either constantly spray the flowers, or buy a humidifier.

Spider mites like to settle in old dried leaves, which you did not remove in time, and then move to the plant. Dust on the leaves is also a comfortable environment for mites, so try to keep your flowers free from dust.

The first symptoms of plant damage

Be careful, do not miss the first symptoms of a spider mite attack on a flower: first, small discolored dots appear, which can grow to the size of spots, a cobweb appears on the back of the leaf, the leaf itself folds. New mites are hatched in the web, and the leaves, meanwhile, are already falling off, the plant weakens, withers and may die.

Ways to fight

Real flower growers do not like to resort to chemical insect control. I don't like it either, but in the case of the spider mite, such a measure is completely justified.

Of course, if you notice the disease in time, at the stage of the first single small puncture points, then you can do with treating the plant with a solution of insecticidal soap: rub it finely, dissolve it well in water and thoroughly rinse each leaf of the damaged plant on both sides. In addition, you need to treat the pot and the place where the flower stands with a solution.

But the problem is that most often we notice the disease even when the plant changes its appearance: spots appear on the leaves and cobwebs on their underside. And ticks are countless. Therefore, you have to use insecticides. Now there is a very large selection of necessary drugs: fitoverm, neoron, fufanon, agravertin. I personally use actellik, which, although it is unsafe for people and animals, but after treatment with actellik, spider mites will not be on my flowers for a long time.

I also heard about the use of special sticks: Plant-Pin and Etisso. They are stuck into the soil with an infected flower, and the active substance (anti-mite poison) dissolves when watering the soil and is absorbed by the roots of the plant. Poison sticks are especially convenient for treating violets, which do not like wet spraying. Unfortunately, I haven’t had to use these drugs yet.

How to treat plants from ticks

It is necessary to carefully treat the flower with chemicals, since the mites can enter a state of diapause and successfully wait out the aftermath of your procedure. By the way, remove all damaged leaves and flowers before processing.

So, dissolve actellic in the ratio indicated by the manufacturers. If you have a 5 ml ampoule, dissolve it in 1 liter of warm water and then pour it into a container with a spray bottle. Spray the entire plant thoroughly. Areas that are difficult to wet with spraying can be wiped off with a sponge soaked in solution. It is desirable to spray not only the diseased plant, but also those that are nearby. I wipe the place under the flower with alcohol.

Insecticide Treatment Safety

In the summer, I take the treated plants outside or in the bathroom if the treatment takes place during the cold season. Do not spray Actellic in the presence of children and animals, as it is a hazard class 3 drug. Smoking while spraying is strictly prohibited.

To protect myself from the toxic effects of the drug, I wear gloves, a cotton respirator from a hardware store, and a thin polyethylene raincoat. After processing the plants, I thoroughly wash my bath with soap, rinse with running water from the shower, throw away the mask, gloves and cape and take a shower.

In especially advanced cases or for your own peace of mind, repeat the treatment after 10-12 days. And do not count on the fact that ticks will not appear again: you need to be very careful with these pests.

Spider mite on indoor plants

Spider mites often infect indoor plants. This small parasite settles on the stems or leaves of flowers. Ticks prefer to stay closer to the root zone, where they suck out sap, interfering with the normal growth and development of the flower.

Almost all growers know how dangerous this insect is. Therefore, it is very important to have the necessary information to detect these parasites and how to fight them.

Today, many methods are known and many drugs have been developed that facilitate the fight against many parasites, including the spider mite. There are also folk remedies that it also makes sense to talk about.


Pest appearance

In total, there are over 1270 species of ticks in the world. The common spider mite is the most common member of the family. Various representatives of this species found in all parts of the world.

When a plant is damaged, it is almost impossible to discern this pest, and even more so its larvae. It is not a blood-sucking parasite, like ordinary ticks, but belongs to the group of arachnids. You need to know this information in order to choose a drug against this pest.

The color of the parasite can be different at the larval stage and an adult representative. Males are colored greenish-yellow, while females are orange and brownish-red. Its body is round, covered with bristles. On bushes and flowers, parasites are located mainly on the inside of the leaf, which makes them even more invisible.

As a rule, the gardener begins to look for available methods to combat this pest, when the leaves are already covered with brown spots on the back, and with an internal web. It is often very difficult to get rid of this pest. The tick is very viable and can hide for a while, but not completely die. Withstanding a long time without food, they can hibernate and wait for a favorable time.


Getting rid of parasites

Dealing with a pest is not so difficult, so if you find it on the site, you should not panic. The main thing is to choose the appropriate method of dealing with strawberry mites and follow it until the insects disappear.

The use of chemicals

This method of killing harmful insects is quite effective. It consists in processing strawberry bushes with special chemicals. There are many medications available to deal with the tick. Among them are such as:

  • Karbofos. It is a moderately toxic agent that, in addition to ticks, destroys other garden pests. It is recommended to process strawberries with it at least 2 times throughout the season. It is best to do this in dry, calm weather at a temperature not lower than + 15 degrees in the morning or evening. The drug should be diluted in accordance with the attached instructions. It is necessary to spray both the outer and inner surfaces of the leaf plate. It is forbidden to use karbofos during flowering.
  • Colloidal sulfur. Also used against a number of pests. Available in powder and paste form. It is recommended to use the product at temperatures from +20 to +30 degrees. In colder weather, the drug does not guarantee a 100% result, and in case of heat above 30 degrees, burns on the leaves may occur. During the season, two treatments are required.
  • Neoron. Refers to contact acaricides, that is, it acts on ticks. Available in 5 ml ampoules. It is distinguished by the fact that it does not harm the bees much. Bushes with strawberries or strawberries should be treated with the drug, following the instructions.
  • Fitoverm and Akarin. They belong to the group of biological pesticides. This means that, if used correctly, they do not harm either human health or beneficial insects. They need to be diluted in a proportion of 20 ml per 10 liters of water, and spraying with these agents is carried out 3 times every 7 days.

It is possible to use Fufanon, Actellik, Moroleks and other chemicals against the pest.

Biological method

It is another measure to combat the strawberry mite and involves the colonization of insects on the affected area, which contribute to the destruction of the pest. It can be a trichogramma that lays its eggs inside the eggs of a mite, as well as some types of phytophagous mites that eat a pest of strawberries.

Such insects can be purchased at specialized stores or biolaboratories. But this tool is not available to everyone and not in all regions.

Agrotechnical techniques

It involves proper maintenance of the strawberry beds, the use of varieties that are resistant to parasites, and the cultivation of plants that repel ticks. So, to get rid of the site of pests in early spring, you should remove and burn the remnants of damaged plants, because it is there that the females of the strawberry mite are located. The rest of the strawberry and strawberry bushes should be thoroughly poured with water heated to 80 degrees. Only after these events can you start the usual care of the culture.

After purchasing a strawberry mustache, each seedling must be warmed up in water, the temperature of which is +45 degrees, lowering them there for 15 minutes and covering it with warm material on top. After warming up, the mustache is placed in cold water, and then dried for at least an hour in the shade. These activities will help protect plants from pests.

As for the choice of varieties, it is better to dwell on those species that have resistance to strawberry mites. These varieties include Zenga-Zengana, Torpedo, Vityaz, Zarya and some others. Every year new types of strawberries appear, so you should carefully study the information about them before purchasing.

It will help to reduce the number of parasites and planting plants next to a strawberry bed, which, with their smell, can scare away ticks. Among them are common tansy, lavender, catnip, rosemary, Dolmat chamomile.

Folk remedies

You can also fight strawberry mites on strawberries with the help of folk remedies. They involve the use of various herbal decoctions and infusions:

  • Infusion of onion peels. For its preparation, 200 g of husk is infused for 5 days in 10 liters of water. After straining, strawberry bushes are sprayed with infusion in spring and autumn.
  • Infusion of garlic. 200 g of fresh garlic is chopped and soaked in a 10 liter bucket of water for 5 days. At least 0.5 liters of infusion should be poured under each plant. To enhance the effect, it is recommended to cover the bed with foil for 2 hours immediately after watering.
  • A decoction of tomato tops. 1 kg of dry tops is poured with 10 liters of water, left for 3-4 hours, and then boiled for 2-3 hours and filtered. Next, the broth is diluted with water in a 1: 2 ratio. It is advisable to add 40 g of laundry soap to the diluted product, after which you can start processing the beds with strawberries.

It is better to combine the above methods for greater efficiency in the fight against ticks. Then the insects will not get used to it, and the result will last for a long time.


Reasons for the appearance

Before you take drastic steps to save your plant, you need to know what conditions are most favorable for the emergence of a pest. And these conditions are incredibly simple - dryness.

That is why spider mite infestation occurs most often in the winter, when central heating makes the air in the room unbearably dry. Unbearable for a rose, but just right for a tick. Therefore, the first thing to do is to humidify both the plant and the air.


Plant damage symptoms

There are the following signs of tick damage to plants:

  1. Brown spots, like holes made by a needle.
  2. Yellow or light green dots.
  3. Falling flowers, leaves.
  4. Slow plant growth.
  5. Silvery cobwebs between the leaves.
  6. The presence of small insects on the back of the foliage, similar to red or yellow moving dots.
  7. A large number of ticks on the web - with a large tick infestation.
  8. The presence of black grains that are easily separated from the plant - tick excrement.


Infection prevention and precautions

It is not enough to know ways to get rid of pests, you still need to do periodic prophylaxis:

  • Maintaining normal moisture.
  • Treat once a month with a biological preparation.
  • Remove fallen leaves in time.
  • Maintain optimal temperature.

Orchid is a capricious but amazingly beautiful plant. You can achieve colorful flowering and health of the bush with proper and high-quality care. To prevent tick infestation, it is necessary to regularly spray the orchid with water or weak biological solutions
