Author(s):
Sudipta Padhan and M Raghuraman
Abstract:
The field experiment was carried out to study the evaluation of the bio-efficacy of chlorantraniliprole against fruit borer of tomato (Lycopersicon esculentum Miller.), and chlorantraniliprole 18.5% SC 40gm a.i. ha-1 was found to be effective in reducing fruit borer population. Application of chlorantraniliprole 18.5% SC 40gm a.i. /ha and chlorantraniliprole 18.5% SC 30gm a.i. /ha were established to be effective in reducing fruit borer of tomato, recording mean overall per cent reduction in larval population by 68.75% and 60.18%, respectively. The overall data on % reduction in larval population is 68.5% in Chlorantraniliprole 18.5%SC 40 gm a.i /ha treated plots which also noted lowest number of damaged fruits (5.36) and highest plot yields (33.04 kg).
