Apple tree biological effectiveness of the dimethoate against spider mites determination

Abstract

European red mites are the most frequent mite in Uzbekistan apple orchards, and they may be found from early spring through harvest. The orange-colored adults of twospotted spider mites overwinter beneath the bark of trees or on weeds. In the spring, populations typically cluster beneath the tree and in nearby areas on broadleaf weeds, brambles, and sucker growth. Damage. Twospotted spider mites induce bronzing on the leaves. Spider mites leave a characteristic webbing pattern on the underside of the leaf.
