Quinclorac. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Quinclorac is an organic compound with the formula C9NH4Cl2CO2H. A colorless solid, it is soluble in hydrocarbons and alcohols. The compound is the carboxylic acid of 3,7-dichloro quinoline.
The product is used at application rates of 75-150 g/ha. [ 15 ] The estimated annual use of mesotrione in US agriculture is mapped by the US Geological Service and shows an increasing trend from its introduction in 2001 to 2018, the latest date for which figures are available and now reaching 4,500,000 pounds (2,000,000 kg).
Triclopyr [1] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) is an organic compound in the pyridine group that is used as a systemic foliar herbicide [2] and fungicide. [3]
Pesticide drift, also known as spray drift refers to the unintentional diffusion of pesticides toward nontarget species. It is one of the most negative effects of pesticide application. Drift can damage human health, environment, and crops. [1][2] Together with runoff and leaching, drift is a mechanism for agricultural pollution. [3]
Herbicide. A field after application of a herbicide. Weeds controlled with herbicide. Herbicides (US: / ˈɜːrbɪsaɪdz /, UK: / ˈhɜːr -/), also commonly known as weed killers, are substances used to control undesired plants, also known as weeds. [1] Selective herbicides control specific weed species while leaving the desired crop ...
Dithiopyr is a preemergent herbicide for crabgrass control in turf and ornamental grasses. It is effective on 45 grassy and broadleaf weeds. [1] Dithiopyr inhibits root growth of susceptible weeds as well as turf grass and thus should be used only on established turf with a well-developed root system. Its duration of efficacy is approximately 4 ...
The resulting extracts were applied to soil flats containing watergrass (Echinochloa crus-galli) as an indicator species at the very high application rate of 100 pounds per acre (112 kg/ha). There was a herbicidal effect from this test, so the extracts were developed on a preparative thin layer chromatographic sheet.
It is used for grass and broadleaf weed control in corn, soybean, peanuts, sorghum, and cotton. It is also used in combination with other herbicides. Metolachlor is a popular herbicide in the United States. [3] As originally formulated metolachlor was applied as a racemate, a 1:1 mixture of the (S)- and (R)-stereoisomers.
