Pendimethalin
Pendimethalin is a selective herbicide used to control most annual grasses and certain broadleaf weeds in field corn, potatoes, rice, cotton, soybeans, tobacco, peanuts and sunflowers. It is used both pre-emergence and early post-emergence.
Incorporation into the soil during cultivation or irrigation is recommended within 7 days following application. The horticultural herbicide is available as emulsifiable concentrate, wettable powder, or dispersible granule formulations.
Uses
1. Pendimethalin protects crops like wheat, corn, soybeans, potatoes, cabbage, peas, carrots and asparagus. It is used to control annual grasses and some broadleaf weeds which interfere with growth, development, yield and quality of agricultural and horticultural crops by competing on nutrients, water and light.
2. In areas where weed infestation is particularly high, yield losses can render wheat production economically unviable. In addition to wheat, a large number of crops are grown in Europe which accounts for a relatively small percentage of total agricultural output. Herbicide options are limited for these minor crops, with few effective herbicides available in the vegetable sector.
3. Long-term field studies performed in Germany by governmental research and advisory institutes together with farmers rank Pendimethalin as an efficient herbicide to control blackgrass, regarding to weed control efficacy, crop yield, treatment costs and environmental impact.
