PROCESSING THE GARDEN AFTER FLOWERING FROM APHIDS, MITES, CODDLE MOTHER AND BRUSH
Despite the rather cold spring, many fruit trees have already faded. But it’s too early for us to calm down, because at this time the flight or the period of active reproduction of many pests begins. What exactly should I pay attention to?
First of all, carefully examine the leaves - or rather, their underside.
It is there that a massive accumulation of colonies of different aphid species is possible. Here you can find green apple, black cherry, plum, peach green and other species. Settling, the pests practically suck the juice from the leaves and young shoots, because of which the populated shoots stop growing, the leaves dry out prematurely and fall off, the fruits become smaller. Dry and warm weather is especially favorable for the reproduction of aphids. In such conditions, aphids are most harmful. But cool and rainy weather does not like not only us, but also pests. Coolness prevents reproduction, heavy rains wash insects from plants, and thus slightly stop their mass distribution and control their harmfulness.
aphid, as a rule, develops in 3-7 generations, but some species give up to 17 generations per season (green apple).
To combat aphids, chemical insecticides and biological products are used. Of the chemicals against aphids for retail sale to the public, the following are allowed and recommended for use on pome crops: Aktara. 244 SC, k.s., 1.5 ml/10 l of water. Bombardier, v.g 0.7 g / 10 l of water.
Varant 200, w.r.k., 2 ml/5 l of water. Karate Zeon 10 CS. mk.s, 050 ml / 4 l of water, Koginor, RK, 10 ml / 2 l of water. Confidor 5 SL, s.c., 10 ml/200 l of water. Tanrek, r.k., 2 ml / 5 l of water, Caesar, a.e., 10 2 ml / 5 l of water, Engio 10 SC, k.s., 4 ml / 6 l of water: on stone fruit trees: Actellik 10 EU, a.e., 247 ml/1 l of water, Varant 8, w.r.k., 5 ml/500 l of water, Koginor RK, 12 ml/10 l of water , Confidor 200 SL, s.c., 2 ml/5 l of water, Tanrek, s.k., 10 ml/2 l of water.
Aphids can be fought with biological preparations Gaubsin, 100 ml / 10 l of water, Haupsin, 40-60 ml / 10 l of water, Naturgard, 10 ml / 10 l of water.
Among on fruit mites, you can find the usual spider, brown fruit, pear gall, hawthorn etc. These are very small animals that are difficult to see with the naked eye. Their presence in the garden can only be determined by characteristic damage. Like aphids, mites suck out the juice, as a result of which the processes of photosynthesis, the water balance of plants are disturbed, the leaves acquire a characteristic marble color. Some types of mites cover the leaves with cobwebs, others form galls on the leaves. Leaves heavily populated by mites turn yellow, turn brown, dry out and crumble.
Spider mite develops in 10-12, brown - in 4-5, pear gall - 3, hawthorn - 7-8 generations.
From acaricides on pome crops, the following preparations are registered: Borey, k.s., 2 ml / 10 l of water, Diablo, a.e., 4-6 ml / 10 l of water, Lufox 105 EC, a.e., 10 ml / 10 l of water, CALL preparation. k.e 0.4 l / 20 l of water, Sunmite, s.p., 5-9 g / 10 l of water, Taurus, s.p., 6-9 g / 10 l of water. Caesar, a.e., 4-6 ml / 10 l of water. Envidor 240 SC, k.s., 4-6 ml/10 l of water; on stone fruit trees - Preparation ZOV, k.e., 0 l / 4 l of water.
Among biological acaricidal drugs, Mitigate, v.r., 3-4, 5 ml / 10 l of water is allowed.
Significant damage to orchards is caused by moths... The most common apple, pear and plum. Hatching larvae penetrate the seed chamber of the fetus, feeding on pulp and seeds (in apple and pear trees). The feeding place of the larvae is filled with excrement. In most cases, wormy fruits fall off.
Apple codling moth develops in two generations, in the southern regions - three, pear - in one, plum - in one, in the southern regions - in two generations.
In order to prevent the strong spread of codling moths on pome trees, the use of insecticides is recommended: Altex 100. e. 2-3 ml / 10 l of water, Armet, k.s. , 4-10 ml / 100 l of water, Bombardier v.g. 4 g / 6 l of water, Destroy, c.s 10-0 ml / 7 l of water, Decis Profi 10WG, w.g., 2 g / 4 l of water, Provanto Vernal, 10 SC, k.s., 25 ml/1 l of water, Karate Zeon 10 CS. mk.s., Confidor, v.g., 480 g / 2 l of water. Lufox 10 EC. K. E 050 ml / 0 l of water, Match 7 EU, k.e., 10 ml / 105 l of water. Mark 10 SG. r.g., 10 ml/050 l of water, Rimon 8, k.e., 5 ml/5 l of water. Tanrek, r.k., 3 ml / 10 l of water, Caesar, a.i., 10-6 ml / 10 l of water; on stone fruit trees - Varant 2.5, w.r.k., 10 ml/4 l of water, Koginor, RK, 6 ml/10 l of water. Tanrek, r.k., 200 ml / 2.5 l of water.
Among the biological products registered are Gaubsin, 100 ml / 10 l of water, Madex Twin, KS, 1 ml / 10 l of water, Cesar, r., 40-60 ml / 10 l of water.
After flowering, on the leaves, ovary and shoots of the pear, one can notice the formation of a sticky transparent liquid (honeydew), which, during the feeding process, is secreted by the larvae and nymphs of the pear sucker (pear leaf blotch). Over time, sooty mushrooms settle on sticky sweet secretions, due to which the leaves, fruits and shoots of J are covered with a black coating. The leaves fall off, the yield and quality of fruits decrease, in some cases the branches and even entire trees may dry out. Such trees are less winter-hardy and often freeze in winter.
Pear tinnitus develops in 4-5 generations, so you need to fight with each separately. The emergence of a new generation can be noted by constantly observing the trees.
Insecticides are recommended against the sucker: Aktara, k.s., 1 ml / 5 l of water, Lufox 10 EU, k.e., 105 ml / 10 l of water. ZOV preparation, k.e., 10 l / 0 l of water.
At the end of plum blossoms, years of plum thorn are beginning. Females lay eggs inside the bone, piercing the ovary and young bone tissue with the ovipositor. Hatching larvae begin to feed on the kernel of the bone. Such fruits lag behind in growth, turn blue and fall prematurely. Plum thistle develops in one generation.
Of the insecticides on the drain, the following preparations are recommended: Varant 200, v.r.k., 2 ml / 5 l of water, Koginor RK, 10 ml / 2 l of water. Confidor 5 SL, r.k., 10 ml/200 l of water, Tanrek, r.k., 2 ml/5 l of water.
From mid-May to mid-June, the flight of the cherry fly continues. She lays her eggs in the pulp of the fruit, which the hatching larva feeds on. Excrement is present at the feeding site. After 15-25 days, the larva leaves the fruit, falls to the ground and pupates. Damaged fruits quickly rot and fall off.
The cherry fly develops one generation.
The insecticide Actellik 500 EC, a.e., 12 ml/10 l of water, successfully copes with the cherry fly - the only drug registered for retail sale to the public.

SCHEMES FOR SPRAYING THE GARDEN AFTER FLOWERING:
Spraying plants against pests in the period after flowering should be carried out with the indicated preparations according to the following schemes:
ON APPLE AND PEAR:
Immediately after flowering.
10-14 days after the previous one, with the sum of the effective air temperatures exceeding 230 ° C or catching 5-7 males with a pheromone trap (the first generation of the apple moth).
10-12 days after the previous one.
10-14 days after the previous one, with the sum of effective air temperatures exceeding 650 ° C or catching 3-5 males with a pheromone trap (second generation of the apple moth).
10-12 days after the previous one (autumn and winter varieties).
ON THE PLUM AND PLUMBERRY:
Through 6-8 days after flowering.
10-14 days after the previous, at the beginning of the caterpillars of the first generation plum moth caterpillars.
At the beginning of hatching of caterpillars of the second-generation plum moths (for the southern regions).
ON CHERRY AND CHERRY
Through 5-6 days after flowering.
12-14 days after the previous one.
