Harvest Time Residues of Carbosulfan 6G in Rice Grain, Straw, Husk, Bran and Soil

摘要

A study was conducted to determine the harvest time residues of carbosulfan 6G (NS) in rice grain, straw, husk, bran and soil. Carbosulfon 6G was applied @ 1000 (NS), 2000 (NS), 1000 (ES) and 2000 (ES) g a.i./ha twice i.e., at 21 and 45 days after transplanting in two seasons during rabi 2011 and kharif 2012 in rice. Rice grain, straw, husk, bran, and soil were analysed for harvest time residues by using HPLC/GC through liquid chromatography. It was found that residues were below detectable level (BDL) in the matrices tested irrespective of the rate of application.
