Technical Abstract: Enhancing environmental quality and sustaining the economic viability of food production are keys to sustainable agriculture. Modern vegetable production uses a variety of materials to manage pest problems. Selecting the proper spray nozzle for the application of liquid products is critical to reducing spray drift which in turn helps keep material out of sensitive off-target areas and can reduce pesticide consumption and cost. ARS and university research studies have demonstrated that spray drift can be minimized by keeping nozzles close to the target, using large droplet nozzles, using adjuvants to decrease the number of small droplets produced and using shields to protect the area being treated. Chemical label recommendations for nozzle flow rate and spray quality are provided to help ensure good application practices. When given flexibility to choose between different types of nozzles, choose those that will produce the largest size of droplet and still provide the desired spray coverage. Producers should also match the nozzles with the spray control system being used to help make applications. Following these equipment guidelines will help vegetable producers reduce costs, damage to nearby non-target areas, and minimize health risks.
