Weed Control in Soybean (Glycine max) with Lactofen Plus Chlorimuron [PDF]
Weed Technology, 1993 Field experiments were conducted over a 3-yr period at three locations to evaluate lactofen at rates of 110 to 220 g ai ha−1applied POST in combination with chlorimuron at 9 g ae ha−1for weed control in soybean. At St. Joseph in 1989 and Baton Rouge in 1990, lactofen at 110, 150, and 170 g ha−1in combination with chlorimuron controlled prickly sida (3 ...

Potential defense-related prenylated isoflavones in lactofen-induced soybean
Phytochemistry, 2011An integrated LC-MS and NMR metabolomic study was conducted to investigate metabolites whose formation was induced by lactofen (1), a soybean (Glycine max L.) disease resistance-inducing herbicide. First, LC-MS analyses of control and lactofen (1)-induced soybean extracts were performed.

Many pesticides in use are chiral compounds containing stereoisomers. However, the environmental behavior and fate of such compounds with respect to enantioselectivity so far has received little attention. In this study, the degradation of lactofen and its main metabolites (acifluorfen, an achiral compound; desethyl lactofen, a chiral compound) in ...

Induction of hepatic peroxisome proliferation in mice by lactofen, a diphenyl ether herbicide
Toxicology and Applied Pharmacology, 1988A technical grade of lactofen (1'[carboethoxy]ethyl 5-[2-chloro-4-[trifluoro-methyl] phenoxy]-2-nitrobenzoate) has been shown to induce liver tumors in mice. To determine a possible mechanism of action, the effect of exposure for 7 weeks to dietary concentrations of 2, 10, 50, and 250 ppm technical grade lactofen and 250 ppm of pure lactofen was ...

Nitric oxide reduces oxidative stress generated by lactofen in soybean plants [PDF]
Pesticide Biochemistry and Physiology, 2010 Nitric oxide (NO) is a molecule able to directly scavenge ROS and end chain reactions, which can be generated by some herbicides. This study aimed to evaluate whether the pretreatment of soybean plants with sodium nitroprusside (SNP) solution, a NO-donor substance, provides protection against oxidative stress generated by lactofen.

Pesticide pollution of surface water represents a considerable danger for the aquatic plants which play very crucial roles in aquatic system such as oxygen production, nutrient cycling, water quality controlling and sediment stabilization. In this work, the toxic effects of the chiral herbicide lactofen and its three metabolites (desethyl lactofen ...

Pesticide residue in agricultural land might led to contamination of fresh waters, creating potential risks to organisms. The environmental behavior of herbicide lactofen may be enantioselective and the metabolites may have high toxic effects in individual or in combination.

A bacterial strain Za capable of degrading diphenyl ether herbicide lactofen was isolated and identified as Bacillus sp. This strain could degrade 94.8% of 50mgL-1 lactofen after 4days of inoculation in flasks. It was revealed that lactofen was initially hydrolyzed to desethyl lactofen, which was further transformed to acifluorfen, followed by the ...

Controlling Weeds Found in Peanut with Lactofen
Crop Management, 2011Field studies were conducted from 2006 to 2008 in south Texas on peanut and in the Texas High Plains under fallow conditions to determine weed control using lactofen applied POST. At the High Plains location, under low humidity conditions, Palmer amaranth control decreased as weed size increased.
