Abstract


An experiment was conducted to identify the right time of spray of botanicals and chemical insecticides for the
control of ber fruit borer, Meridarchis scyrodes M. Spray time significantly influenced the per cent mortality of pest. First
spray with 5% neem seed kernel extract (NSKE), second spray with 0.07% acephate and third spray with 5% NSKE given on
15th September, 30th September and 15th October. Among the three sprays, first spray with 5% NSKE on 15th September recorded
the lowest per cent borer damage (28.12). The highest fruit yield (73.85 kg/plant) and benefit cost ratio (1.72) were also
recorded with first spray on 15th September.
