Abstract

Bioefficacy of imidacloprid against termites in sugarcane.

Abstract

Imidacloprid 70 WS and imidacloprid 200 SL were evaluated in Talawadi, Tamil Nadu, India, in 1996/97 and 1997/98 for their efficacy against termites (Microtermes obesi, Odontotermes obesus, O. assmuthi, O. wallonensis, and Trinervitermes biformis) in sugarcane as sett dip and spray over setts in furrows. Sett dip of imidacloprid 70 WS at 0.1 and 0.15% and spray over setts of imidacloprid 200 SL at 250 and 375 ml/ha-1 resulted in increased germination of setts. These treatments protected the crop from termite damage and were as effective as chlorpyrifos 20 EC (5 l/ha-1). These treatments increased cane yield but did not significantly affect juice quality. The residues in sugarcane juice were below the detectable limit.
