Improved Weed Control Benefits Growers and the Environment
Grower costs have been reduced by more than $30/acre thanks to Kurt Hembree’s research on improving herbicide performance on tree and vine crops. Weeds compete with crops for important resources such as irrigation water, fertilizers, and nutrients. Weeds also harbor harmful insects, rodents, and interfere with harvest efficiencies. Weeds increase labor and supply costs while reducing crop quantity and quality. Key treatment methods developed by Hembree include:
• Treat weeds when they are less than 4” tall
• Use appropriate spray nozzles for the conditions
• Increase the spray volume to improve weed coverage
• Combine herbicides to broaden control and reduce weed resistance
The potential savings on Fresno County’s 460,000 acres of fruit and nut crops using these treatment methods is nearly $14 million. The impact of improved weed control includes fewer weeds; fewer herbicide treatments needed; and reduced costs associated with equipment, fuel, and labor. This benefits both growers and the environment.
