Bok av Umbarkar Prashant S
In view of the importance of the greengram crop and seriousness of various pests, it becomes absolutely necessary to have comprehensive information on different aspects of the insect pest management. Hence, the detailed information on bio-ecology and management of pod borer complex of greengram were given here. The gram pod borer commenced from 1st week of August and exhibited a significant negative correlation with minimum temperature and evening RH. Incidence of spotted pod borer was started from 2nd week of August and exhibited a significant negative correlation with minimum temperature. Pink pod borer commenced from the 3rd week of August and exhibited a significant negative correlation with evening RH. The genotype GM-2K-5 recorded the lowest population of pod borers of greengram. The lower larval population of pod borers were observed in treated plot than untreated. The treatments with indoxacarb 0.0075%, spinosad 0.009%, cypermethrin 0.009% and profenophos 0.05% were the most effective for the control of pod borer complex of greengram. The highest seed yield was obtained from the treatment of indoxacarb 0.0075%. The highest C:B ratio was obtained from cypermethrin 0.009%.
