Pyraflufen

Description:

Pyraflufen, with the CAS number 129630-17-7, is a selective herbicide primarily used for the control of broadleaf weeds and certain grasses in various crops. It belongs to the class of chemicals known as diphenyl ethers and functions by inhibiting the enzyme protoporphyrinogen oxidase, which is crucial in the biosynthesis of chlorophyll. This inhibition leads to the accumulation of toxic porphyrin compounds, resulting in plant cell death. Pyraflufen is characterized by its rapid action and effectiveness at low application rates, making it an attractive option for integrated weed management strategies. It is typically applied post-emergence and is known for its low toxicity to non-target organisms, including mammals and birds, when used according to label directions. Additionally, it has a relatively short residual activity in the soil, which helps minimize the risk of carryover effects on subsequent crops. As with any herbicide, proper handling and application practices are essential to maximize efficacy and minimize environmental impact.

2-Chloro-5-(4-chloro-5-difluoromethoxy-1-methylpyrazol-3-yl)-4-fluorophenoxyacetic acid monohydrate

CAS: 129630-17-7

2-Chloro-5-(4-chloro-5-difluoromethoxy-1-methylpyrazol-3-yl)-4-fluorophenoxyacetic acid monohydrate (2,4,5P) is a phenoxy herbicide that has been shown to be an effective broadleaf and grass weed control agent. 2,4,5P is a granule formulation that can be applied by helicopter or ground equipment. It has synergistic effects with glyphosate when applied together to soybean plants and can be used in combination with other herbicides for more effective weed control.
