Abstract
Field investigations were conducted for three seasons from July 2006-2007 to test the efficacy of Fantac (N-ATCA) in transplanted rice and also determine its harvest time residues in paddy grain, straw, husk and soil by HPLC. It was applied at the rate of 25, 50, 75 and 100 mL/100 L respectively. The results revealed that foliar spray of this agrochemical on rice crop did not produce any significant effect on the general growth parameters but increased the number of grains/panicle. The residues of fantac were found to be < 0.05 μg/g at the time of harvest which are below MRL and thus Fantac can be considered as environmentally safe.
