Description

Tembotrione [Iso] CAS NO 335104-84-2 is a selective, systemic herbicide belonging to the triketone chemical class, which functions as a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor. This mode of action makes it a critical tool for effective post-emergence weed control in major field crops. It is primarily utilized in the agricultural industry by professional growers and formulators seeking reliable, broad-spectrum solutions for managing resistant and hard-to-control broadleaf and grass weeds.

Application

The primary and derived applications of Tembotrione [Iso] include:

• Selective Herbicide for Corn (Maize): Core application for post-emergence control of a wide spectrum of weeds, including glyphosate-resistant species.
• Weed Management in Sorghum: Used for protecting sorghum crops from competitive weed pressure.
• Formulation Intermediate: Serves as a key active ingredient (AI) for agricultural chemical companies developing proprietary herbicide formulations.
• Control of Problematic Weeds: Effective against velvetleaf, lambsquarters, pigweed, and nightshade species.
• Resistance Management Programs: Integrated into crop protection strategies to rotate modes of action and delay herbicide resistance development.
• Agricultural Research & Development: Used in R&D settings for bioassay testing and development of new crop protection solutions.
