HOW TO FIGHT MITES ON FRUIT TREES
Ticks often live on fruit crops - apple, pear, hawthorn. Let's get to know them by sight.
Red apple mite - adults are small (up to 0 mm), dark red, the larva is red. Winter orange
red rounded eggs in cracks in the bark, at the base of the kidneys, on the fruitlets and annelids. With a high number of eggs, the branches acquire a reddish tint. The larvae hatch during budding and flowering. During the season, the pest gives three to four generations. The tick lives on the underside of the leaf, and small grayish-brown spots appear on the top. Over time, the entire leaf becomes brownish-bronze or grayish-brown. It often dries up completely. If there are a lot of ticks, the trees give small fruits, shoots grow weakly.
Brown fruit mite - an adult about 0 mm greenish or reddish-brown. The life cycle is about the same as that of the red apple mite, four to five generations per season. On the upper side of the leaf, mainly at the base and along the veins, light blurry spots appear that can cover the entire plate. The leaf becomes whitish.
Hawthorn mite - females of summer generations are dark red, wintering ones are bright red, 0-5 mm long. Females hibernate in small colonies under the lagging bark on boles, in forks and other secluded places. In mid-April, they begin to feed on blossoming buds, then move on to the leaves, where they soon lay their eggs. During the summer, the tick gives seven to nine generations. Damaged leaves turn yellow, their edges are bent and pulled together by a thick thin web, under the cover of which pest colonies are located. Such leaves eventually dry out and fall off.

WHAT ARE THE WAYS TO PREVENT AND PROTECT TREES FROM MITES?
In early spring, when the larvae hatch, treat the trees with an infusion of mustard, dandelion, and chamomile.
With a high number of mites (100-400 eggs per 1 m of one-three-year-old branches) before flowering, and if necessary, then after flowering, sprinkle with one of the preparations: colloidal sulfur (50 - 100 g per 10 liters of water), sulfaride (40-100 g per 10 liters of water), mitak (20-40 ml per 10 liters of water), neoron (15-20 ml per 10 liters of water), apollo (4 ml per 10 liters of water), rovikurt (10 liters per 10 liters of water).
In the summer, but no later than 30-40 days before harvesting, if the number of ticks increases, re-treatment with one of the same preparations will be required. Protection against ticks is usually combined with the fight against the codling moth.
