Penoxsulam—Structure–activity relationships of triazolopyrimidine sulfonamides
Bioorganic and Medicinal Chemistry, 2009The discovery of the sulfonamide herbicides, which inhibit the enzyme acetolactate synthase (ALS), has resulted in many investigations to exploit their herbicidal activity. One area which proved particularly productive was the N-aryltriazolo[1,5-c]pyrimidine sulfonamides, providing three commercial herbicides, cloransulam-methyl, diclosulam and ...

CYP72A15 confers resistance against penoxsulam to Echinochloa phyllopogon
Pesticide Biochemistry and PhysiologyAs the weed Echinochloa phyllopogon has rapidly developed multi- and cross-resistance to several herbicides, we aimed to determine the mechanism underlying penoxsulam resistance in weeds. There was no target mutation in the tested population, and P450 enzyme activity was significantly higher in the penoxsulam-treated resistant population, confirming ...

Laboratory and field dissipation of penoxsulam, tricyclazole and profoxydim in rice paddy systems
Chemosphere, 2013Rice cultivation relies on pesticide applications to ensure high yields. However, the regular use of pesticides seriously affects the quality of neighboring surface water systems. Thus complete knowledge of the environmental fate and dissipation of pesticides in the paddy rice environment should become available. So far only a few studies have provided

A competitive enzyme-linked immunoassay (ELISA) for the quantitation of Penoxsulam [2-(2,2-difluoroethoxy)-6-(trifluoromethyl-N-(5,8-dimethoxy[1,2,4]triazolo[1,5-c]pyrimidin-2-yl))benzenesulfonamide] in ground and surface waters was developed. This immunoassay utilizes magnetic particles as the solid phase to which polyclonal rabbit anti-Penoxsulam ...

Photodegradation of Penoxsulam
Journal of Agricultural and Food Chemistry, 2006This study was carried out to characterize the photodegradation of penoxsulam and to evaluate the significance of photolysis for its fate and dissipation. Degradation studies of (14)C-labeled isotopes of penoxsulam in a "merry-go-round" reactor suggest that aqueous photodegradation proceeds via three possible pathways: cleavage of the sulfonamide ...

Rice Cultivar Response to Penoxsulam
Weed Technology, 2007A study was conducted in 2005 and 2006 to evaluate the response of 10 rice cultivars to penoxsulam applied at 70 g ai/ha to two- to three-leaf rice. A related study was conducted in 2004 and 2005 to compare the rice response to applications of penoxsulam at 35 and 70 g/ha and bispyribac-sodium at 28 g ai/ha.

Partitioning of Penoxsulam, a New Sulfonamide Herbicide
Journal of Agricultural and Food Chemistry, 2005Penoxsulam (trade name Granite) is a new acetolactate synthase (ALS) inhibitor herbicide for postemergence control of annual grasses, sedges, and broadleaf weeds in rice culture. This study was done to understand the equilibrium phase partitioning of penoxsulam to soil and air under conditions simulating California rice field conditions.

Interference of allelopathic rice with penoxsulam‐resistant barnyardgrass
Pest Management Science, 2017AbstractBACKGROUNDDespite increasing knowledge of allelopathic rice interference with barnyardgrass, relatively little is known about its action on herbicide‐resistant barnyardgrass. The incidence of herbicide‐resistant barnyardgrass is escalating in paddy fields. Knowledge of the interference of allelopathic rice with herbicide‐resistant barnyardgrass

Persistence Behavior of Penoxsulam Herbicide in Two Different Soils
Bulletin of Environmental Contamination and Toxicology, 2017Penoxsulam, a new post emergence herbicide is suspected to be toxic to aquatic organisms, crop plants and also to soil microbial community even at low concentrations. Laboratory studies were therefore performed to examine the persistence of, penoxsulam in two different soils at two application rates (0.5 and 1.0 µg g-1).
