How to identify a tick on a strawberry
The size of the pest is microscopic - the length of females is 0.2 mm, males are 1.5 times smaller. It is important to know what a tick-infested strawberry looks like:
- the bushes are underdeveloped;
- the leaves are small, wrinkled and twisted, acquired a yellowish tint;
- on the back of the plates there is a silvery bloom;
- chopping berries;
- fruits dry out without having time to ripen;
- winter hardiness decreases.
The larvae take only 2-3 weeks to mature. The same length of time lasts for intensive growth before becoming an adult.
You should study all the signs of a strawberry mite on a strawberry, partially shown in the photo. Treatment should be started immediately. The short growth period of the larvae and the huge fertility lead to the fact that up to five generations of the pest can appear in one season.
The mite brings maximum harm in the second half of summer, it multiplies most actively in August.
How to tell a nematode from a tick on a strawberry
The symptoms of strawberry mite and nematode damage are similar, both have a microscopic size. The main difference is the type of leaves. When a strawberry mite is affected, their color brightens, and because of the nematode, leathery spots of a dark green color appear, the central veins swell in several places, which resembles fractures.
The plants infected with the worm have reddish leaf stalks. They are shortened and twisted, but thick. There is a strong branching of the stems, the ugly shape of the ovaries, buds, flowers, fruits. The stems and whiskers thicken, and pale green growths appear.
There are different types of strawberry mites - spider mites, cyclamen, transparent
Why do strawberries have mites?
The tick has microscopic dimensions, it usually spreads over the site due to wind, rain, birds, and humans - on clothes, shoes, tools. Infection of neighboring bushes is carried out through the whiskers and adjoining leaves. The following conditions contribute to the appearance of a pest:
- shaded place;
- high planting density;
- irregular weeding and loosening;
- non-compliance with crop rotation;
- use of contaminated planting material.
The weather is considered an important factor for the appearance and reproduction.Spider mites prefer dry and sunny areas, while transparent and cyclamen ones like irrigated soil. Optimal breeding conditions are 19-25 ° C and high (80-90%) humidity.
With the onset of autumn, the number of ticks decreases, they go to winter at a temperature of 12 ° C and below. To survive the cold, pests climb into the heart of a bush or folds of young ground leaves.

In combination with phytoseiulus, another predatory mite is also used - abliseius
Onion peel
To destroy the pest, you need to prepare an infusion of dry husks - pour warm water (10 liters per 0.2 kg), leave for five days, strain. You can spray strawberries for ticks before flowering and after harvesting. 2-3 treatments are recommended at 5-day intervals.

The first treatment is carried out in the spring after the snow melts at the beginning of the growth of the bushes - pay special attention to the leaf petioles where the pest hibernates. Then you need two more sprays at weekly intervals.
If strawberries are severely affected by a tick, then during budding it is worth using a more saturated product - pour 0.7 kg of garlic with 10 liters of boiling water, leave for a day, dilute 1:10.

Prevention and protection measures for strawberries from strawberry mites
Strawberry mites can strongly infect strawberries, leading to their death. It is important not only to destroy pests in a timely manner, but also to take preventive measures so that they do not appear:
- buy only healthy planting material in proven places;
- do not plant strawberries in lowlands, shading;
- loosen and weed the soil in a timely manner;
- follow the planting scheme so that the bushes are ventilated and well lit;
- regularly cut off old foliage, get rid of unnecessary mustache and sockets;
- timely and competently feed the culture;
- after harvesting, but until mid-August, strawberries can be cut off - the plant residues can be collected and burned;
- if there are few foci of infection, then it is better to dig these bushes and burn them;
- observe crop rotation - return strawberries to their old place after at least four years, maintain the same interval after nightshades, cucumbers;
- change the mulch annually;
- periodically update the strawberries and transplant to a new place.
Seedlings can be disinfected by dipping them in hot water for 10-15 minutes. Maximum temperature 65 ° C. You only need to dip the top of the outlet and the leaves into the water, so as not to harm the root system.
Strawberry mite resistant strawberry varieties
It is not easy to kill strawberry mites, especially in advanced cases. It is possible to reduce the risk of this pest by using varieties resistant to it, for example, Albion, Vityaz, Zarya, Zenga Zengana, Omskaya early (partial resistance), Torpedo, Khonei and Elsanta.
The tick rarely infects forest and small-fruited strawberries, although it can be a carrier of it. Varieties with delicate foliage and glucose-rich fruits are especially susceptible to the pest.
Conclusion
It is better to deal with strawberry mites on strawberries in a complex manner. Attention should be paid to pest-resistant varieties, and preventive measures should be taken. You can destroy the tick with chemicals and folk remedies.
