Biodegradation of diphenyl ether herbicide lactofen by Bacillus sp. YS-1 and characterization of two initial degrading esterases.

Science of the Total Environment, 2021
The extensive use of the diphenyl ether herbicide lactofen in recent years has caused serious environmental problems. Therefore, detoxification and elimination of lactofen from the environment are urgently required.

Soil Amendment: A Technique for Soil Remediation of Lactofen

Bulletin of Environmental Contamination and Toxicology, 2007
Lactofen, a member of the diphenyl ether chemical family, shows great potential for the control of broadleaf weeds associated with leguminous crops. It presents a high degree of selectivity when applied post-emergence to soybean and peanut crops. This paper presents the persistence of lactofen under a soybean crop under various conditions, including ...

Controlling Weeds Found in Peanut with Lactofen

Crop Management, 2011
Field 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.

Droplet size impact on lactofen and acifluorfen efficacy for Palmer amaranth (Amaranthus palmeri) control

Weed technology, 2019
Herbicide applications performed with pulse width modulation (PWM) sprayers to deliver specific spray droplet sizes could maintain product efficacy, minimize potential off-target movement, and increase flexibility in field operations.

Induction of hepatic peroxisome proliferation in mice by lactofen, a diphenyl ether herbicide

Toxicology and Applied Pharmacology, 1988
A 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 ...

Effect of Acifluorfen and Lactofen Application Timing on Peanut Injury and Yield

Crop Management, 2011
More emphasis is being placed on protoporphyrinogen oxidase (PPO)‐inhibiting herbicides such as acifluorfen and lactofen for the control of acetolactate synthase (ALS)‐resistant weeds. The objective of this research was to determine the visual injury, canopy development, and yield losses from these herbicides applied to peanuts post‐emergence ...

Lactofen Systems for Broadleaf Weed Control in Peanuts (Arachis hypogaea)

Weed Technology, 1990
Weed management systems using a chloroacetamide herbicide applied preplant incorporated (PPI) and at cracking (AC) plus lactofen applied AC and early postemergence (POST) controlled at least 98% of common lambsquarters. Similar systems using a chloroacetamide herbicide applied PPI and early POST plus lactofen applied early POST and postemergence (POST)

Weed Control in Soybean (Glycine max) with Lactofen Plus Chlorimuron

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 ...

Foliar washoff and runoff losses of lactofen, norflurazon, and fluometuron under simulated rainfall

Journal of Agricultural and Food Chemistry, 1994
Lactofen [(~~-2-ethoxy-l-methyl-2-oxoethyl5-[2-chloro-4-(trifluoromethyl)phenoxyl-2-nitrobenzoatel washoff from velvetleaf (Abutilon theophrasti Medic.) and common cocklebur (Xanthium strumarium L.) foliage was investigated. Plants were sprayed with lactofen at 0.4 kg of ai ha-l and subjected to 2.5 cm of rainfall in 20 min at 1 and 24 h after ...

Effect of Lactofen Application Timing on Yield and Isoflavone Concentration in Soybean Seed

Agronomy Journal, 2007
Postemergence application of the herbicide lactofen is known to increase phenolic compounds such as isoflavones in soybean [Glycine max (L.) Merr.] plants. We hypothesized that lactofen increases isoflavone levels in seed when applied at the R1 and R5 stages of development. Field research evaluated the effect of lactofen application timing and cultivar
