New insecticide thiamethoxam (cruiser) tested as seed treatment of sorghum, was compared with conventionally recommended insecticides, carbofuran 3G and phorate 10 G. Bioefficacy and persistence studies conducted on two formulations viz. 350 FS and 70 WS of thiamethoxam showed that both the formulations in low and high doses were effective against sorghum shootfly, Atherigona soccata Randani and stem borer, Chilo partellus (Swinhoe) and gave higher grain yield as compared to carbofuran and phorate. Both the formulations were found safe. Samples of matured grains of sorghum, green slatks and soil collected after harvest did not show any residues of thiamethoxam from both formulations at their low and high doses.
