Matar, CS (metribuzin, 600 g/l)

Professional weed management with Matar, CS

For modern farmers specializing in soybeans, potatoes, and tomatoes, early-season weed control is essential for ensuring yield potential. The systemic herbicide Matar, CS, manufactured by Hangzhou Ruijiang Chemical Co., Ltd., offers a high-concentration formula (600 g/l of metribuzin) designed to provide reliable soil-based protection against a broad range of broadleaf weeds.

Technical Profile and Mode of Action

Matar, CS utilizes metribuzin, a triazine compound, formulated as a concentrated suspension. This ensures excellent stability in the spray tank and uniform coverage of the soil surface. As a selective, systemic herbicide, its primary application is pre-emergence. Once applied, it creates a protective barrier in the upper soil layer. When weeds germinate, the roots and shoots absorb the active ingredient, which effectively shuts down photosynthesis, leading to weed mortality before they reach the critical competition phase.

Target Weeds

This formulation is engineered to handle highly aggressive weeds that threaten crop health in the early vegetative stages. It is effective against:

• Common ragweed (Ambrosia artemisiifolia) and redroot pigweed.
• Common lambsquarters and common chickweed.
• Shepherd's purse, purple dead-nettle, and field pansy.
• Pale smartweed.

Implementation and Best Practices

Produced by Hangzhou Ruijiang Chemical Co., Ltd. and brought to the market by Defenda, this herbicide is a staple in integrated crop management. Given its selective nature, the key to success lies in matching the dosage to the soil texture—lower rates are recommended for lighter, sandy soils to prevent any phytotoxic effects on the crop. Matar, CS is favored by professionals for its ability to clear the field for optimal crop growth, reducing the need for mechanical weeding and protecting the yields of soybeans and potatoes during their most vulnerable period of development.
