Description

Methyldymron is a selective herbicide belonging to the chemical class of phenylpyridazinones. This compound is valued for its effective pre- and post-emergence control of a broad spectrum of annual grasses and broadleaf weeds in key agricultural crops. It is primarily utilized by agrochemical formulators and manufacturers for producing crop protection solutions. Methyldymron CAS NO 42609-73-4 offers reliable performance in integrated weed management programs.

Application

• Primary Use as a Herbicide: Formulated for pre- and post-emergence control of weeds in various cropping systems.
• Rice Paddy Weed Management: Effective against common weeds in flooded rice fields, helping to secure yield.
• Cereal Crop Protection: Used in wheat, barley, and other cereal crops to manage competitive weed flora.
• Industrial Agrochemical Manufacturing: Serves as a key technical-grade active ingredient (TGAI) for formulating suspension concentrates (SC), wettable powders (WP), and other end-use products.
• Selective Weed Control in Legumes: Applied in certain leguminous crops for targeted weed suppression without harming the crop.
• Non-Crop Area Management: Can be utilized for vegetation control in industrial sites and right-of-ways.

Quality Control

Our technical-grade Methyldymron is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, potency, and impurity profiles. We provide full traceability and Certificates of Analysis (COA) are available upon request, detailing results for all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
