A TECHNOLOGY FOR MANAGEMENT OF LITCHI MITE USING IPM MODULES UNDER SUB TROPICS OF BIHAR

Abstract

Litchi mite is the threat to litchi growers as both nymphs and adults damage the leaves, inflorescence and young developing fruits. Therefore, keeping in view the importance of litchi mite, Aceria litchii field trial was conducted at ICAR-NRCL, Muzaffarpur to manage the pest. Experiment was laid out in RBD design with seven treatments comprised of pruning of affected twigs (July & October) and miticides (chlorfenapyr & propargite) sprayed twice in July and once in October months to evaluate the efficacy of various integrated approaches. Results revealed that initial mite infestation ranged from 97.33 to 98.80%. No mite nfestation was recorded at flowering stage in pruning and removal of affected twigs followed by two spraying of chlorfenapyr 10 EC (0.03%) at 15 days interval during July and again pruning in October with one spraying of Chlorfenapyr followed by spraying of propargite 57 EC (0.17%) with 1.33% mite infestation. The higher mite infestation was noticed during August (50.00) to November (80.00) and again the population start increasing from February nwards on new shoots.
