Tembotrione

Type: Herbicide

Mode of Action: 

• Group 27: Pigment synthesis inhibitors. HPPD Inhibitor

Common Product Names: Laudis

What is it?

Tembotrione is a selective herbicide primarily used in the cultivation of corn. It is highly effective against a broad spectrum of broadleaf and grass weeds, making it a vital tool for farmers seeking to maintain healthy and productive crop fields. The active ingredient belongs to the triketone chemical family and is valued for its post-emergence weed control capabilities.

How does it work?

Tembotrione works by inhibiting the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) in plants. This inhibition blocks the biosynthesis of carotenoids, leading to the depletion of these pigments. Carotenoids are critical for capturing light energy and protecting chlorophyll from photooxidation. When Tembotrione disrupts this process, the affected weeds experience chlorosis (yellowing of leaves) followed by necrosis (death of plant tissue), ultimately resulting in their elimination from the crop field.

Benefits

• Post-Emergence Application: Its post-emergence activity allows farmers to apply the herbicide after weeds have emerged, providing flexibility in application timing and enhancing weed control strategies.
• Crop Safety: Tembotrione is designed to be selective, meaning it targets weeds while being safe for use on corn crops, reducing the risk of crop damage.
