Assessment of electrostatic sprayer against citrus psylla Diaphorina citri Kuwayama in Kinnow mandarin

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.
