Thiamethoxam 70 WS, a new promising seed dress for the suppression of sorghum shootfly.

摘要

An experiment conducted during kharif 2003, at Dharwad, Karnataka, India showed that seed dressing with thiamethoxam 70 WS at 5 and 4 g a.i./kg seeds was very effective in reducing the percentage of dead hearts caused by Atherigona soccata compared with the untreated control and the standard insecticide carbofuran 3G at 3 g/m row. Sorghum grain yield in the respective treatments was 31.54, 30.00 and 17.12 q/ha. Thus, the seed dress with thiamethoxam 70 WS at 4 and 5 g a.i/kg seeds proved to be best for the management of shootfly and afforded highest protection of 85.0 and 89.4%, respectively, over control. Thiamethoxam 70 WS at any of the dosages tested did not show any deleterious effects on seedlings.
