Description

Calcium Methanearsonate is an organoarsenical compound primarily used as a selective herbicide. This product is valued for its effectiveness in controlling specific weed species in key commercial crops, offering a targeted solution for agricultural management. It is essential for agricultural professionals and formulators seeking reliable pre-emergent and post-emergent weed control in established turf and certain cropping systems.

Application

• Selective Herbicide in Turf Management: Used for controlling crabgrass and other annual grassy weeds in established lawns, golf courses, and sod farms.
• Agricultural Crop Protection: Applied in certain row crops for pre-emergent and post-emergent control of specific weed species.
• Industrial Vegetation Control: Component in formulations for managing unwanted vegetation in non-crop areas like fence lines and drainage ditches.
• Professional Landscaping: A tool for landscape maintenance professionals to maintain weed-free ornamental plantings and turf.
• Research & Development: Serves as a reference standard or active ingredient sample in agrochemical research and formulation development.
