Microbial degradation is the main process controlling the environmental dissipation of the nematicide oxamyl. Despite that, little is known regarding the microorganisms involved in its biotransformation. We report the isolation of four oxamyl-degrading bacterial strains from an agricultural soil exhibiting enhanced biodegradation of oxamyl. Multilocus sequence analysis (MLSA) assigned the isola...

A kinetic study of the degradation of phosalone in an alkaline medium was undertaken by using a pneumatic stopped-flow system. A rapid semiautomatic method is proposed for determining phosalone. Linear calibration graphs up to 8.0 x 10(-5) M (detection limit = 1.40 x 10(-6) M) were obtained, with a measurement period of only 3.5 s per sample and a relative standard deviation of 1.4%. Several pe...

The global decline of amphibians has sparked interest in the role that pesticides may play. Pesticides in nature typically exist in combinations, but given the vast number of chemicals used, most toxicological experiments necessarily have examined one pesticide at a time. I examined how four commercial formulations of pesticides (diazinon, carbaryl, malathion, and glyphosate) affected the survi...

Laboratory feeding trials were conducted to assess the comparative impact of registered and new unregistered insecticide-treated bran baits on nontarget epigcal arthropods. Yellow mealworm beetles and larvae (Tcllebrio molitor, L.) (8 surrogate, surface-dwelling tenebrionid) were individually housed in containers and exposed to five different dosages (quantities) of bran bait treated with three...

A simple, small-bolt method was developed and refined for evaluating and screening treatments being considered as prophylactics against bark beetles (Coleoptera: Curculionidae: Scolytinae). Using this method, 4 insecticide products (3 active ingredients) were evaluated against the southern pine beetle, Dendroctonus frontalis Zimmermann, intermittently during a period spanning 1 day to 9 months ...

122 Novembre ‘10 T he city of Bhopal in Madhya Pradesh, India suffered the world’s worst ever industrial disaster on December 3, 1984, when around 500,000 inhabitants were exposed to Methyl Isocyanate (MIC) released from the Union Carbide India Ltd (UCIL) pesticides factory and about 3,000 to 20,000 people died. The UCIL manufactured carbaryl, aldicarb and sevidol a formulation of carbaryl and ...
