Description

Metobenzuron is a selective herbicide belonging to the phenylurea chemical class, widely recognized for its effective pre- and post-emergence weed control. Its primary value lies in its targeted action against a broad spectrum of annual grasses and broadleaf weeds in various crops, offering farmers a reliable tool for crop protection and yield optimization. This product is essential for professionals in the agrochemical manufacturing, formulation, and agricultural research sectors seeking high-quality active ingredients.

Application

• As a key active ingredient in the formulation of selective herbicide products for agricultural use.
• For pre-emergence weed control in crops such as cereals, rice, and certain vegetables to prevent weed establishment.
• For post-emergence application in managed agricultural systems to control escaped weeds.
• In agricultural research and development for studying herbicidal modes of action and efficacy.
• Used in combination with other herbicides in tank mixes or co-formulations to broaden the weed control spectrum and manage resistance.
• For the protection of non-crop areas, such as industrial sites and right-of-ways, where selective vegetation management is required.

Quality Control

Our Metobenzuron is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to meet technical or higher-grade specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your 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, which can affect product stability and handling properties.
