Description

Mecoprop-P CAS NO 18221-59-5 is a selective, post-emergence phenoxy herbicide belonging to the aryloxyalkanoic acid family. It is valued for its effective control of broadleaf weeds in cereal crops and turfgrass, offering a cost-efficient solution for modern agriculture. This active ingredient is essential for formulators and manufacturers in the agrochemical industry developing professional-grade herbicide products.

Application

• Selective Herbicide Formulations: Primary use in post-emergence herbicide products for controlling a wide range of broadleaf weeds, including chickweed, clover, and plantain.
• Cereal Crop Protection: Widely applied in wheat, barley, oats, and rye to protect yield by eliminating competing weed species without harming the crop.
• Turf and Lawn Management: Used in professional turf management for golf courses, sports fields, and sod farms to maintain weed-free grass.
• Industrial Vegetation Control: Employed in non-crop areas such as roadsides, railways, and utility rights-of-way for vegetation management.
• Synergistic Herbicide Mixtures: Often formulated with other phenoxy herbicides or sulfonylureas to broaden the spectrum of weed control and combat resistance.
• Agricultural Research & Development: Serves as a reference standard and key intermediate in R&D for developing new agrochemical solutions.
