Abstract

ABSTRACT: The main objective of present investigation is to study seasonal incidence of aphid on potato crop and establishing correlations with different weather parameters viz; temperature (maximum temperature, minimum temperature and average temperature), relative humidity (morning relative humidity, evening relative humidity and average relative humidity), wind velocity, rainfall. The experiment was carried out at farmer’s field at Kodit Tal. Purandar, Dist. Pune (Maharashtra) during Rabi season 2020-2021. The studies on seasonal incidence revealed that the first incidence of aphid was commenced after three weeks of planting at 48th SWM and it remains active throughout the crop growth period. The peak infestation of aphid (496 aphids/100 compound leaves) was observed at 1st SMW (1st week of January, 2021) when maximum temperature (28.39¬¬°C), minimum temperature (13.24°C), average temperature (20.82°C), morning relative humidity (91.88%), evening relative humidity (54.33%), a
