Apple
Major diseases and pests in apple requiring yearly combat with them are apple scab disease, powdery mildew, late brown rot, apple fruit moth, apple sawfly, leaf miners, aphids and scale insects, leaf-rollers, leaf-feeding caterpillars geometer moth, sucking bugs, mites and others. Combating the pests is conducted through taking agricultural and chemical measures from the winter rest of the trees to the defoliation in the fall.

With the pruning for fruiting all dead and broken branches and twigs are cut and burnt, and the dead trees are uprooted. Removed are the nests of the brown-tail, the white fruit moth, the egg rings of the lackey moth, and the mummified fruits are harvested and burned.

Soil tillage in March contributes to the destruction or deterioration of the conditions for the development of the apple sawfly larvae, the larvae and pupae of leaf-mining moths, the producers of the scab disease, brown rot and other diseases.

Winter spraying in the second half of march with Acarzine 3% or R3 oil – 3% for the extermination of the scale insect larvae and the eggs of the acari insects, aphids, geometer moths and others.

Pre-flowering spraying – takes place from the mouse ear phase until the flower color stars to show, from the end of March till the middle of April. It’s aimed against the main diseases and pests.

Excise the branches with signs of powdery mildew disease .

Second after flowering spraying  – held in mid-May against scab, powdery mildew, leaf miners, leaf-rollers, leaf chewing caterpillars, winter moth and other pests  with one of the mentioned in the first after flowering spraying insecticides and fungicides.

Third after flowering spraying – held during the second half of May, mainly against scab and first generation codling moth larvae.

–          against scab spray with Rubigan 12 ЕC – 0,06%, Punch 40 ЕC – 0,0075%, Sistan 12 Е – 0,06%, Vectra 10 SC – 0,03%, Topsin М 70 VP – 0,15%, Folikur 250 EV– 0,04%, Shavit 72 DVG – 0,2%, Silit 40 SK – 0,16%.

Fourth after flowering spraying – Held during the first ten days of June, mainly against scab, codling moth larvae and against the first generation of californian shield aphid with insecticides and fungicides mentioned in the third after flowering spraying.

Fifth and sixth spraying – held against codling moth, californian shield aphid and against scab with the already indicated for these pests pesticides. The fifth spraying is carried out at the beginning of the second half of June, and the sixth – in the third ten days of the month. The sixth spraying is last one – against scab and first generation codling moth. Only in highly susceptible varieties and rainfalls may be carried out another 1-2 sprayings against scab.

In July and August develops the bulk of the population of the californian shield aphid. Against apples harm are doing also leaf-rollers, leaf miners, crust eating insects. Also there are conditions for mass reproducing of the red mite. Against these pests are held 4-5 more sprays, mainly against apple moth.

Seventh, eighth, ninth, tenth and eleventh sprayings are held from mid-July to late August – early September.
