title: Persistence of chlorantraniliprole granule formulation in sugarcane field soil.
abstract: Chlorantraniliprole, an anthranilic diamide insecticide with novel mode of action, is found effective against several lepidopteran as well as coleopteran, dipteran, and hemipteran pests. The present studies were carried out to study the persistence pattern of chlorantraniliprole on sugarcane field soil following application of granule formulation. The residues of chlorantraniliprole were estimated using high performance liquid chromatograph (HPLC) and confirmed by liquid chromatograph-mass spectrometry (LC-MS/MS). Following application of chlorantraniliprole (Ferterra 0.4G) at 100 and 200 g a.i. ha(-1), the average initial deposits of chlorantraniliprole were observed to be 0.88 and 1.59 mg kg(-1), respectively. These residues dissipated below the limit of quantification (LOQ) of 0.01 mg kg(-1) after 56 days of the application of insecticides at both the dosages. The half-life values (t 1/2) of chlorantraniliprole were worked out to be 8.36 and 8.25 days, at recommended and double the recommended dosages, respectively.
