Sam Marx, UNL research technologist, discusses PWM technology, challenges in the spray application industry, and his work to improve the efficiency of spray nozzle designs using computational fluid dynamics.
University researchers are seeking 30 Nebraska spray applicators for a sprayer cleanout study. The study will help extension application educators learn about applicator practices and how to direct their educational efforts.
A 120-foot sprayer can have as many as 96 nozzles and screens and stow away as much as 15 gallons of pesticide residue in its nooks and crannies after an application is done. Consider these tips for thoroughly cleaning your sprayer to avoid off-target contamination.
Achieving the most effective and consistent spray droplet size helps provide for precision application of pesticides, which saves input costs and reduces off-target movement. University researchers using a pulse-width modulation sprayer studied the best droplet size for effective weed control with six herbicides used in Nebraska crop production.
Learn enhanced stewardship for dicamba and 2,4-D, how to better mitigate spray drift, and nozzle recommendations to improve control of troublesome weeds among other topics at an advanced clinic for pesticide spray applicators March 6 in Syracuse.
Factors leading to dicamba injury and how growers will need to practice best management practices with all dicamba applications in 2018 to help reduce injury to susceptible crops and other plants. This article discusses key practices to implement.
