Monsoon
Monsoon is a sulfonylurea herbicide for maize crops: nicosulfuron 40 g/L in a suspension concentrate against annual and perennial grass weeds and some annual broadleaf weeds.
Main advantages
- Nicosulfuron 40 g/L — an acetolactate synthase inhibitor
- Reddish tint after a week — a visible sign of action
- Annuals 2–6 leaves, perennials 10–15 cm — the weed stage
- Only weeds that have emerged — later flushes not covered
Overview
About this product
Monsoon is a single-component herbicide: nicosulfuron 40 g/L in a suspension concentrate. The active is taken up by the leaves and stems, moves to the roots and inhibits acetolactate synthase, an enzyme of amino-acid synthesis, so cell division stops; after about a week the weeds take on a reddish tint.
It acts only on weeds that have already emerged. Maize is treated once at the 4–10 leaf stage at 1.0–1.25 l/ha, when annual grasses have 2–6 leaves and perennials are 10–15 cm.
Spray volume 200–300 l/ha, temperature from +15 to +25 °C. Pack size 10 l.
