Comparative analysis of biorational and chemical management methods against fruit fly on citrus

Abstract

Fruit flies lay eggs under the peel, inside the rind of the fruit leading to premature fruit drop and reduced marketability. This research gives a comparison among a wide range of bio rational as well as chemical methods. The data of per cent fruit infestation received after three sprays was analysed in RBD which showed that the cumulative mean of per cent fruit infestation was found in case of plots sprayed with Chlorpyriphos 50% EC + Cypermethrin 5% EC i.e. 5.39% and the coefficient of variation recorded at 6.95%. The experiment was carried out in the cv. Nagpur mandarin (Citrus reticulata Blanco) at Regional Fruit Research Station, Katol during late monsoon season of the year 2024. The experiment was laid out in Randomized Block Design (RBD). The cumulative mean values with respect to per cent fruit infestation showed that Chlorpyriphos 50% EC + Cypermethrin 5% EC @ 1ml/l with 5.39 per cent fruit infestation to be the most effective treatment.
