Description

Primisulfuron is a selective, systemic sulfonylurea herbicide known for its high efficacy at low application rates. This compound is valued for its ability to provide broad-spectrum control of grass and broadleaf weeds in key cereal crops. It is primarily utilized by agricultural chemical formulators and manufacturers serving the global crop protection industry. The product is supplied to meet the stringent quality and consistency requirements of professional agrochemical production.

Application

• Active ingredient in post-emergence herbicide formulations for corn (maize).
• Key component in weed control programs for cereal crops, including wheat and barley.
• Used in tank mixes and combination products to broaden the spectrum of weed control and manage resistance.
• Formulated as wettable powders (WP), water-dispersible granules (WG), or suspension concentrates (SC).
• Applied in agricultural settings for control of annual and perennial grass weeds.
• Integrated into sustainable farming practices due to its low use rate and favorable environmental profile.

Quality Control

Our Primisulfuron is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Quality assurance includes comprehensive testing against established analytical methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
