Quizabria

Quizabria is a selective post-emergence herbicide that removes grass weeds from broadleaf crops without harming them. Because it targets an enzyme form that only grasses possess, sugar beet, cotton, soybean, sunflower, onion, tomato, field pea and vineyard tolerate it fully — while bermudagrass, johnsongrass, barnyard grass, wild oat and blackgrass stop growing and die. It handles both annual and perennial grasses; the perennials simply need the higher rate.

Características

• —Registered across eight crops, from sugar beet to vineyard
• —Low rates: 75-100 ml/ha
• —Tank-mixable with common sugar beet broadleaf herbicides
• —HRAC Group A/1 — the grass-specific mode of action

Cómo actúa

Quizalofop-P-ethyl inhibits acetyl-CoA carboxylase (ACCase) in grasses, halting fatty-acid and membrane synthesis at the growing point. The meristem rots, young leaves yellow and pull out easily, and the plant dies over one to three weeks. Broadleaf species carry a different ACCase form and are not affected. HRAC Group A / Group 1. PHYTOTOXIC TO CEREALS — never apply to wheat, barley or other cereal crops.
