Major Weeds Controlled: Difficult to control grasses, including barnyard grass, crabgrass, fall panicum, foxtails, goosegrass, and horseweed (Conyza canadensis) and bracken fern.
Major Weeds Not Controlled: Most broadleaf and perennial weeds.
For Best Results: Use a minimum of 20 gallons of solution per acre. Apply a single postemergent broadcast application per season.
Cautions and Precautions: Do not use surfactant in ornamental applications. Low temperature and humidity decrease absorption.
Residual Activity: Residual control of grasses germinating from seed will persist for 6 to 10 weeks, depending on field conditions.
Volatility and Leaching Potential: Leaching potential is high.
Symptoms and Mode of Action: Asulam is a carbamate herbicide; primary mode of action is to inhibit DHP synthase, an enzyme involved in folic acid synthesis. Asulam also appears to be a mitotic inhibitor preventing function in meristematic tissues. Symptoms include chlorosis in young weeds and plant stunting followed by necrosis.
