Description

Pyrithiobac-Sodium is a selective, post-emergence herbicide belonging to the pyrimidinyloxybenzoic acid chemical class. It is valued for its effective control of key broadleaf weeds, particularly in cotton crops, offering growers a reliable tool for integrated weed management. This compound is primarily utilized by agricultural chemical formulators and producers within the crop protection industry.

Application

• Selective Herbicide for Cotton: The primary application is for the post-emergence control of troublesome broadleaf weeds in cotton fields, including morning glory, pigweed, and velvetleaf.
• Agricultural Formulations: Used as the active technical ingredient in the manufacture of various commercial herbicide formulations such as soluble concentrates (SL) and wettable powders (WP).
• Integrated Weed Management (IWM) Programs: Serves as a key component in resistance management strategies, providing an alternative mode of action to other herbicide classes.
• Industrial and Non-Crop Use: May be employed for vegetation control in certain non-crop areas, following local regulatory approvals and guidelines.

Quality Control

Our Pyrithiobac-Sodium is manufactured under a strict quality management system to ensure batch-to-batch consistency and efficacy. The product undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with agreed 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 after opening to prevent moisture absorption and potential degradation.
