Management of Mites in Agricultural Field Crops
Mites are non-insect pests having four pairs of legs. The factors resulting in increasing population of mites include, environmental condition, change in cropping pattern and others. In addition to damage of crops, some species are known as predatory mites, which are red in colour.
Damage: The damaged leaves have light yellow spots, stippling, bronzing, curling, crinkling, and finally defoliation. Sometimes, deformity of plant parts are also observed. Minute spider-lings are also observed on damaged parts of the plant. Hot weather favours the mites and thus lead to increase in their population rapidly. Some mites also act as vector for viral diseases. The infestation of mites is observed mainly in Okra, Brinjal, Chilli, Paddy, Cotton, Sapota, Mango, Tea, Pigeon pea, Coconut, Sorghum, and a few others.
