An experiment was conducted at Regional Agriculture Research Station, College of
Agriculture, Waraseoni, Bagalaght, Madhya Pradesh during the 2014-15 to study on
the evaluation of Thiamethoxam 25 per cent WG for the management of stem borer
(Scirpophaga incertulasWalker), leaf folder (Cnaphalocrocis medinalis Guenee), gall
midge (Orseolia oryzaeWood Mason), leaf hoppers viz., green leaf hopper (Nephotettix
virescens Distant), brown plant hopper (Nilaparvata lugens Stal), in rice crop.
Thiamethoxam 25 per cent WG used in the experiment was different doses i.e. @ 20 g
a.i. /ha, 25 g a.i. /ha, 30 g a.i. /ha, 50 g a.i. /ha, and 100 g a.i. /ha, with insecticidal
check Imidacloprid 17.8 SL @ 30 ml a.i./ha. Two sprays of insecticides were applied
at fifteen days interval. The most effective dose of thiomethoxam 25 per cent WG in
controlling the rice insect pests was 50 g. a.i./ha followed by 30 g a.i. /ha and 25 g a.i.
/ha. Per cent reduction of insect pests over untreated plot after final sprays was followed
this order of efficacy: Thiamethoxam 25 per cent WG @ 20 g a.i. /ha> 100 g a.i. /ha, >
Imidacloprid 17.8 SL @ 30 ml a.i./ha.. Highest cost benefit ratio (1:21.69) was observed
in thiamethoxam 50 per cent WG @ 20 g a.i. /ha.
