Abstract
Field evaluations were
conducted during Kharif and Rabi seasons of 2019-2020 at two
locations in Thondamuttur and Pooluvapatti village of Coimbatore district,
Tamil Nadu, India to assess the efficacy of certain insecticides against web
worm, Antigastra catalaunalis (Dup.) infesting sesame. The mean percent
reduction in leaf and capsule damage low in all the insecticidal treatments its
proved that significantly superior over the in reducing the pest population.
The overall mean percent reduction in leaf damage was recorded in the treatment
with Chlorantraniliprole 18.5 SC @ 27.75 g a.i./ha (83.26% and 79.96% for
location 1 and 2 respectively) in both the locations during both the seasons
and next best treatment Spinosad 45 SC@ 33.75 g a.i./ha (76.35% and 74.73% for
location 1 and 2 respectively) compared to untreated check. The mean percent
reduction in capsule damage over control was registered in the treatment with
Chlorantraniliprole 18.5 SC @ 27.75 g a.i. /ha (95.63% and 91.51% for location
1 and 2 respectively) next best treatment Spinosad 45 SC@ 33.75 g a.i./ha
(81.15% and 78.64% for location 1 and 2 respectively) compared untreated check.
Maximum yiled in the treatment of Chlorantraniliprole 18.5 SC @ 27.75 g a.i./ha
(600.33 and 571.99 kg/ha for location 1 and 2 respectively) in untreated check
(318.93 and 327.97 kg/ha for location 1 and 2 respectively).
