Abstract:
An experiment was conducted in Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology Meerut, (U.P.) India during the Kharif 2019. The data showed that the BPH incidence was started from 33th standard week (third week of August) and continued till 44th standard week (first week of November). And it attends its peak level during the 38th standard week (third week of September) with 15.17 BPH/hill when temperature max., min, maximum, minimum relative humidity and rainfall 33.5 0C, 23.2 0C, 93.7, 62.2 per cent and rainfall 2.3 mm were recorded. However, minimum Rice Brown plant hopper population 1.23BPH/hill recorded that at 33th standard week (third week of August). Correlation studies between mean populations of Brown plant hopper and weather factor exhibited non significance positive correlations with maximum, minimum temperature and maximum, minimum relative humidity with, (r = +0.0186), (r = +0.175), (r = +0.417), and (r = +0.301), respectively. While rainfall had non significance negative correlations (r = -0.427) Brown plant hoppers populations during Kharif, 2019.
