Timing sprays against pink bollworm Pectinophora gossypiella (Saund.) of cotton



Timing sprays against pink bollworm Pectinophora gossypiella (Saund.) of cotton



Indian Journal of Agricultural Sciences 47(10): 521-524



In 1973-5 cotton J205 was sprayed with 1 kg carbaryl a.i./ha at 7-, 11- or 15-day intervals, and in 1975-6 at 7- or 11-day intervals commencing at first evidence of pink bollworm (P. gossypiella) infestation. Spraying at intervals of 7 or 11 days was equally effective and gave significantly higher yields than at 15-day intervals or the untreated control.
