Abstract

Field experiments were conducted to evaluate and standardize the efficiency of electrostatic sprayer for checking citrus psylla Diaphorina citri population in kinnow mandarin orchards using the recommended insecticide imidacloprid @ 0.0071% and compared to standard knapsack sprayer and tractor mounted power sprayer. The results revealed that the use of electrostatic sprayer was significantly efficient in reducing >30% spray volume, covered significant more area (4.8-5.6 ha/ day), is labour saving (1 labour per operation) and much effective in reducing D. citri population by >80% after 14 days of spray in kinnow mandarin orchards.
