Behaviour of sulcotrione and mesotrione in two soils

Pest Management Science, 2007
AbstractThe behaviour of sulcotrione, a recently introduced triketone herbicide, in various soil types was studied under laboratory conditions. In particular, degradation and sorption processes were examined on Ghent and Perpignan soils. Kinetics showed that the degradation of sulcotrione was influenced by biotic and/or abiotic factors.

Degradation of Mesotrione Affected by Environmental Conditions

Bulletin of Environmental Contamination and Toxicology, 2016
With the widespread use of mesotrione, its residues have become increasingly serious and caused a series of environmental problems in northern China. To reduce the harm of these residues, we investigated the degradation effect of mesotrione in typical soils in northern China at different temperatures, soil moisture, pH values and initial concentrations.

Activity of mesotrione on resistant weeds in maize

Pest Management Science, 2002
AbstractMesotrione is a new callistemone herbicide that inhibits the HPPD enzyme (p‐hydroxyphenylpyruvate dioxygenase) and introduces a new naturally selective tool into weed‐management programmes for use in maize. Mesotrione provides control of the major broad‐leaved weeds, and it can be used in integrated weed‐management programmes depending on the ...

Metabolism of the 4-Hydroxyphenylpyruvate Dioxygenase Inhibitor, Mesotrione, in Multiple-Herbicide-Resistant Palmer amaranth (Amaranthus palmeri)

Journal of Agricultural and Food Chemistry
Metabolic resistance to the maize-selective, HPPD-inhibiting herbicide, mesotrione, occurs via Phase I ring hydroxylation in resistant waterhemp and Palmer amaranth; however, mesotrione detoxification pathways post-Phase I are unknown. This research aims

New procedures for simultaneous determination of mesotrione and atrazine in water and soil. Comparison of the degradation processes of mesotrione and atrazine

Environmental Monitoring and Assessment, 2011
A method for the determination of residues of mesotrione, atrazine and its degradation products: deethylatrazine, hydroxyatrazine, deisopropylatrazine, desethyldesisopropylatrazine in a variety of water and soil matrices has been developed. Mesotrione is a new selective herbicide for use in corn, which has been substituted for atrazine, which has been ...

Evaluation of mesotrione tolerance levels and [14C]mesotrione absorption and translocation in three fine fescue species

Weed Science, 2019
AbstractFine fescues (Festucaspp.) are cool-season grasses used in low-maintenance turf areas. Mesotrione is a PRE and early-POST herbicide used during establishment of most cool-season turfgrasses, excluding fine fescues. Currently, efforts are being made to breed for increased tolerance to mesotrione in fine fescues to enhance weed control during ...

Mesotrione and Glufosinate in Glufosinate-Resistant Corn

Weed Technology, 2008
Field experiments were conducted in 1999 and 2000 to evaluate early POST (EPOST) and late POST (LPOST) control of common ragweed and giant foxtail with mesotrione at 70, 105, and 140 g ai/ha alone and in mixtures with glufosinate at 300 g ai/ha in glufosinate-resistant corn.

Mechanism of Antagonism of Mesotrione on Sulfonylurea Herbicides

Weed Science, 2007
Studies were conducted to determine if altered absorption, translocation, or metabolism were the basis for the reduction in sulfonylurea herbicide efficacy on foxtail species when mesotrione was mixed with a sulfonylurea herbicide. Green foxtail and yellow foxtail plants were grown in the greenhouse and treated at the four-leaf stage with14C-labeled ...

Simulated Solar Light Irradiation of Mesotrione in Natural Waters

Environmental Science & Technology, 2006
Photolysis is expected to be a major degradation process for pollutants in surface waters. We report here the first photodegradation study on mesotrione, a new triketone herbicide for use in maize. In a first step, we investigated the direct photolysis of mesotrione at 365 nm from a kinetic and analytical point of view.

Photosynthetic responses and accumulation of mesotrione in two freshwater algae

Environ. Sci.: Processes Impacts, 2014
Photosynthetic responses and accumulation of mesotrione in Microcystis sp. and Scenedesmus quadricauda were investigated by PAM fluorometry, HPLC and SDAPCI-MS.
