Description

Vernolate CAS NO 1929-77-7 is a selective thiocarbamate herbicide used for pre-emergence weed control. It is valued for its effectiveness in managing annual grasses and broadleaf weeds in various crop systems. This product is primarily needed by agricultural chemical formulators and producers serving the crop protection industry.

Application

• Pre-emergence Herbicide: Used for controlling weeds in crops such as soybeans, peanuts, and tobacco before weed seedlings emerge.
• Selective Weed Control: Effective against annual grasses like crabgrass and foxtail, as well as certain broadleaf weeds.
• Agricultural Formulations: Serves as an active ingredient in the manufacture of emulsifiable concentrate (EC) and granular herbicide formulations.
• Soil-Applied Treatment: Applied to the soil surface and incorporated to create a protective barrier against weed germination and growth.
• Integrated Pest Management (IPM): A component in rotational herbicide programs to manage weed resistance.
