BASF program provides extensive hands-on training for applicators.
Through the On Target Application Academy training sessions, BASF and Bob Wolf, Ph.D., Wolf Consulting and Research, have educated thousands of growers on herbicide application best practices since 2012. The program, which was developed by BASF in conjunction with Dr. Wolf, is a one-of-a-kind educational opportunity that provides growers extensive hands-on training for better awareness of herbicide application best practices. Included in the training is important information on preventing and managing drift.
With weed resistance and tough to control weeds continuing to challenge growers across the country, combined with the introduction of advanced crop protection products and spray technologies, there’s a growing need for training to help manage the complex environment.
"The On Target Application Academy offers growers details around best management practices and factors that affect their herbicide application," said Dr. Wolf. "The changing weed management landscape is causing growers to employ a drift management plan that includes multiple strategies to ensure proper application."
Below are Dr. Wolf’s five top recommendations for herbicide application best practices:
No. 1: Select the correct nozzle. Proper nozzle selection is key to reducing spray drift. Choosing the right nozzle for speed, pressure and the chemical being applied helps minimize drift while maintaining protection efficacy.
No. 2: Use appropriate pressure. It is common practice to lower the pressure to manage spray drift, as low pressure creates larger droplets.
However, newer Venturi nozzle designs – commonly referred to as air induction – should be used at pressures ranging from 50 to 80 psi. Newer nozzles operating at higher pressures are able to reduce drift while increasing the coverage potential on the targeted area.
No. 3: Watch application speeds. When using rate controllers, changes in speed across a field will affect the spray pressure. Higher speeds require higher pressure to deliver the correct volume, lower speeds the opposite. Thus, as applicators are making speed changes, they are impacting the droplet size. For a given application, avoid major adjustments in speed.
No. 4: Avoid adverse weather conditions. Adverse weather conditions, including high winds or inversions, are problematic for drift. Applicators have no control over the weather. The best option is to choose not to spray when environmental conditions are not favorable.
No. 5: Stay abreast of other technologies. Consider other technologies to reduce drift potential, including the use of shields, pulse-width modulation or drift reduction additives.
In addition to application training, the On Target Application Academy educates growers on proper equipment set up, including calibration and clean-out, and plant biology, to help them achieve the most effective and sustainable weed control possible, and to help mitigate off-target applications.
The On Target Application Academy is holding courses throughout 2013. BASF expects more than 2,000 growers will receive training this year. Events remaining for 2013 are as follows*:
