Tactics and strategy of acaricide on apple

The observations revealed that an active vital activity mite pest runs on the underside of leaves. When mass outbreaks in July and August phytophage moves to the upper side of the leaf. In areas covered by the settlement web of leaves, under which live colonies of the pest. bright spots first appear on damaged leaves, which gradually increases, leaves turn yellow, deformed, wither and fall off. All acaricides annually in varying degrees, are used for the control of mites in gardens, provide the most efficient when used at intervals of 6-9 days.When extending the interval between treatments to 9-12 days efficacy gradually decreased, and does not provide reliable protection. Against Brown mite they exhibit the highest efficiency at the 3-5th day after the treatment, but after 10 and 15 days after spraying their effect is reduced by 50-70%.
