Abstract

Experiments on newer insecticides viz., imidacloprid @ 0.0045%, acetamiprid @0.004%, thiomethoxam @ 0.005%, abamectin @ 0.0009 %, fipronil @ 0.01%, thidicarb @ 0.075%, spinosad @ 0.0096 % and indoxacarb @ 0.006 % were carried out to test their efficacy against bud fly on linseed during Rabi 2008-09 and 2009-10. Results revealed that spinosad @ 0.0096 % gave significant lowest bud fly infestation i.e. 9.4 per cent with higher per cent reduction (80.2 per cent) over control. The highest yield (1889.6 kg/ ha) was obtained in spinosad @ 0.0096 % treated plot followed by thiomethoxam 0.005 % (1632.00 kg/ ha).

Abstract

The efficacy of some botanicals powder viz., Neem leaf powder (Azadirachta indica), soapnut powder (Sapindus trifoliatus), turmeric powder (Curcuma longa) @ 10 and 20 g/ kg seed, Vasambu rhizome powder (Achorus calamus) @ 5 and 10 g/ kg seed along with a chemical insecticide, Deltamethrin @ 40 mg /kg seed of moong were evaluated as post harvest grain protectants against pulse beetle, Callosobruchus chinensis. Based on parameters like seed germination, seed moisture and insect infestation, Vasambu rhizome powder @ 10 g /kg seed and Deltamethrin @ 40 mg /kg seed were observed most effective against pulse beetle infesting moong bean up to twelve months of storage without deteriorating the viability of seed while Neem dry leaf powder, soapnut powder and turmeric powder were least effective.

Abstract

Brinjal shoot and fruit borer, Leucinodes orbonalis Guenee is a very serious insect of brinjal. During the present investigation, six insecticides were evaluated under field conditions. Regarding the efficacy of insecticides, Imidacloprid 17.8 SL @ 250 g a.i./ha proved most effective which was closely followed by Indoxacarb 14.5 SC @ 50 g a.i./ha and Dimethoate 30 EC @ 1 lit/ha. Maximum fruit yield (220.61 q/ha) was obtained by the treatment of Imidacloprid followed by Indoxacarb (217.88 q/ha) and Dimethoate (216.22 q/ha).
