Rice Cultivation

Selective control of grassy weeds, sedges, and broadleaf weeds in paddy systems.

Weed Control

Effective against Echinochloa spp., Cyperus difformis (smallflower umbrella sedge), Cyperus rotundus (purple nutsedge).

Post-Emergence Application

Best applied after weed emergence and before crop canopy closure for optimal effect. Integrated Weed Management (IWM): Works well in combination with other herbicides as part of an IWM strategy to reduce resistance pressure. Formulation Benefits: The EW formulation improves mixing and handling efficiency while ensuring fast absorption and systemic activity in target weeds.

Fast-acting

Quick uptake into target weeds, providing rapid visible effects within 24 hours of application.

Water-based formulation

High solubility and dispersion in water ensure efficient coverage and herbicide activity.

Low application rates

Economical usage due to the high potency of the 37% active content.

Temperature

Store at 15–30 °C in a dry, cool environment

Packaging Options

1 L, 5 L, 25 L HDPE containers, bulk quantities available

Shelf Life

2 years under recommended storage conditions

Stability

Stable under dry, cool, and well-ventilated storage conditions; avoid exposure to direct sunlight Transport: Ensure secure, upright storage; protect from extreme temperatures during transport
