Menibria

Mesobria combines mesotrione with nicosulfuron for maize. The pairing is deliberate: nicosulfuron is the stronger on grasses, mesotrione on broadleaf weeds, and together they cover a spectrum neither reaches alone. Mesotrione also produces the distinctive bleaching symptom — treated weeds turn white within days — which gives an unusually clear early read on whether the application worked. Two different modes of action in one product is also sound resistance management.

Characteristics

• —Two modes of action in one product — broader spectrum and better resistance management
• —Nicosulfuron covers grasses, mesotrione covers broadleaf weeds
• —Visible bleaching within days gives an early read on performance
• —Single post-emergence pass in maize
• —HRAC Groups F2/27 and B/2
• —Reduces the need for a second herbicide application

How it works

Mesotrione inhibits HPPD, blocking carotenoid synthesis — without carotenoids to protect it, chlorophyll is destroyed by light and the weed bleaches white, then dies. Nicosulfuron inhibits ALS and stops branched-chain amino-acid synthesis. Two unrelated targets mean a weed must overcome both at once. HRAC F2/27 + B/2.
