Tebuthiuron is a relatively non-selective, soil-activated herbicide. It works by inhibiting photosynthesis. It is used to control a broad range of herbaceous, woody, annual, and perennial weeds in non-cropland areas, rights-of-way, and industrial sites.
Tebuthiuron is a broad-spectrum herbicide used to control weeds in non-cropland areas, rangelands, rights-of-way, and industrial sites. It is effective against both woody and herbaceous plants in grasslands and sugar cane. Weeds controlled by tebuthiuron include alfalfa, bluegrasses, chickweed, clover, dock, goldenrod, mulleins, and others. Woody plants require a period of 2 to 3 years to be completely controlled.
Tebuthiuron is sprayed or applied as dry granules or pellets to the soil surface, preferably just before or during the period of active weed growth. It is compatible with other herbicides.
