Topramezone technical is a selective post-emergence herbicide belonging to the pyrazolone class, primarily used for controlling broadleaf and grass weeds in corn and other crops. Topramezone Herbicides inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD), leading to the disruption of carotenoid biosynthesis in target plants. This results in bleaching and subsequent necrosis of the weeds. The other identifier is UNII: W4934JAQ65 for international herbicide trade. Scimplify is a globally established Topramezone Technical manufacturer and agrochemical supplier, delivering formulation-ready technical material through a robust manufacturing process, comprehensive regulatory documentation (CoA), traceability, and global supply capabilities, ensuring reliable lead times and quality assurance across all grades.

Post-emergence in corn crops to control a wide range of broadleaf and grass weeds.
Healthy crop development by eliminating competitive weed species.
Store at room temperature (typically 15–30°C or 59–86°F).
Store in a cool, dry, and well-ventilated area, away from sources of ignition, direct sunlight, and incompatible materials such as strong oxidizing agents.
Keep in original, tightly sealed containers to prevent contamination, degradation, and moisture absorption.
Available in 1 kg, 5 kg, 10 kg, and 25 kg containers. Custom packaging can be provided upon request to meet specific requirements.
Topramezone is a selective herbicide used post-emergence to control broadleaf and grass weeds in crops like corn.
It inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD), disrupting carotenoid biosynthesis in target plants, leading to bleaching and death of the weeds.
When used as directed, Topramezone has low toxicity to mammals. However, it is classified as a reproductive toxin (Category 1B), so appropriate precautions should be taken during handling and application.
Yes, it can be tank-mixed with other compatible herbicides to broaden the spectrum of weed control. Always refer to the manufacturer's guidelines for specific mixing instructions.
It is primarily used in corn (field corn, sweet corn, and popcorn) to manage various weed species.
Topramezone is very toxic to aquatic life with long-lasting effects. Avoid application near water bodies and ensure proper measures to prevent runoff.
As with any herbicide, repeated use of Topramezone alone can lead to the development of resistant weed populations. It is advisable to use it as part of an integrated weed management program, rotating with herbicides of different modes of action.
