Comparative Bioefficacy of Insecticides Against Sawfly, Athalia Lugens Proxima (Klug) on Radish

Nine insecticidal treatments were evaluated against Athalia lugens proxima (Klug) on radish at Junagadh during 2007–08. The results showed that the spinosad 0.007%, thiodicarb 0.075%, quinalphos 0.05% and endosulfan 0.07% were highly effective. Significantly the highest radish yield (216.39 q/ha) was recorded with spinosad 0.007%. However, it was found statistically at par with thiodicarb 0.075% (202.50 qt/ha), quinalphos 0.05% (194.25 qt/ha) and endosulfan 0.07% (190.00 qt/ha). On the basis of cost benefit ratio (CBR), endosulfan 0.07% was found the most economical.
