Incidence of rosette flowers by pink bollworm in Bt and non-Bt cotton and their relationship to weather parameters

Author(s):
P Likhitha, Dr. DB Undirwade and Dr. US Kulkarni
Abstract:
In 2018-19 rosette flowers ranged from 1.14 to 26.12 per cent in non-Bt cotton and from 1.09 to 15.86 per cent in Bt cotton. In 2019-20, the corresponding values for non-Bt cotton were 1.1 to 26.15 and 1.42 to 14.24 for Bt cotton. Correlation studies revealed that per cent rosette flowers in 2018-19 and 2019-20 exhibited significant positive and significant negative correlation with maximum temperature, minimum temperature, morning relative humidity, evening relative humidity, rainfall and rainy days respectively.
