ENVIRONMENTAL FATE
The fate of benfuracarb was studied under field conditions in brinjal fruits and soil following foliar spray application at 0.25 and 0.50 microg g(-1) by HPLC. At 0.25 microg g(-1), benfuracarb persisted up to 7 days both in soil and brinjal but at 0.50 microg g(-1), benfuracarb residues persisted up to 10 and 12 days in soil and brinjal fruits, respectively. The persistence of benfuracarb residues, both in soil and brinjal, followed first-order kinetics. The half-life values of benfuracarb in soil and brinjal fruit were found to be 3.54 and 3.90 days at 0.25 microg g(-1) and 3.75 and 4.73 days at 0.50 microg g(-1), respectively.
Usage: Benfuracarb was first report by T. Goto et al, and develop by Otsuka chemical company in 1981, introduced by England, France and Spain in 1984.
Application: To control insect pests (especially Chrysomelidae, Elateridae, Lissorhoptrus oryzophilus, Plutella xylostella and Aphididae) in citrus, maize, rice, sugar beet and vegetables. Applied mainly as soil treatment (0.5-2.0 kg a.i./ha for maize, 1.0-2.5 kg/ha for vegetables, 0.5-1.0 kg/ha for sugar beet), or seed treatment (0.4-1.5 kg/100 kg seed). Foliar sprays (0.3-1.0 kg/ha) are also used on vegetables and fruit; rice is treated at 1.5-4.0 g/nursery box at transplanting.
