Georgia: Pesticide Training Program Has Lowered Drift Complaints

A state program aimed at teaching farmers and other pesticide applicators how to properly apply pesticides continues to limit pesticide drift in Georgia.

The educational training system, called “Using Pesticides Wisely,” was created by University of Georgia Cooperative Extension and the Georgia Department of Agriculture.

UGA Extension weed scientist Stanley Culpepper, who developed the training, credits Georgia farmers’ excellent teamwork and decision-making for the low number of pesticide drift complaints in Georgia in 2017.

“We’ve surveyed over 3,000 people since the required classroom trainings began in 2015, and 99 percent of them have said the training has been worthwhile. Over 98 percent of them have said the training will help them improve on-target pesticide applications. That’s fulfilling for sure,” Culpepper said.

Since trainings began, drift complaints to UGA Extension offices have been reduced by 68 percent. In 2017, there were more than 2,700 official investigations into auxin off-target deposition across 24 states; there were no reported cases in Georgia, he said.

“While this year’s season is still ongoing, currently the number of official investigations into auxin off-target drift are remarkably low,” Culpepper said.

UGA research has identified 15 factors that should be considered to successfully manage off-target pesticide movement, including the spray nozzle, spray pressure, and spray speed. Understanding the influence of boom height and land terrain is also extremely important, and it’s paramount that pesticide applicators understand the sensitivity of plants near treated areas. This can help applicators determine where they should not apply a particular herbicide.

All of these factors are highlighted during the trainings that educate Georgia farmers and other pesticide applicators, many of whom are experiencing this type of in-depth training for the first time.

The classroom trainings were supplemented by a one-on-one training program that was established in 2017 to provide education in the field. UGA Extension agents visited with applicators to reinforce what they taught in the classroom.

“The one-on-one trainings gave county agents another opportunity to train and educate growers and applicators about the numerous factors that affect drift. It was an opportunity to meet and form relationships with not only growers, but also the farm applicators, and hopefully help them avoid potentially bad drift situations down the road,” said Jeremy Kichler, Colquitt County Extension coordinator and Agriculture and Natural Resources agent.

Culpepper credits the program’s success to the support of UGA Extension Associate Dean Laura Perry Johnson.

“Her support ultimately allowed Extension to commit an untold number of hours to the project over the last four years,” he said. “I don’t think there’s anywhere else where the county agents actually give the one-on-one applicator trainings like we do here in Georgia. That doesn’t happen without … an administrator who understands the value.”

Georgia farmers grow more than 40 high-value vegetable and fruit crops that are highly susceptible to drift damage, especially when they’re produced near row crops like auxin-tolerant cotton and soybeans. Growing up on a family farm in North Carolina, Culpepper understands what’s at stake for farmers and the need for growers to be better stewards of resources.

“When you’re helping an applicator or grower get better because they want to get better, there’s nothing more rewarding,” Culpepper said. “When it’s your best friend’s farm, your family’s farm, you’re around it day in and day out — then you have a reality check. That’s what keeps me focused. I know in our state that if you’re applying pesticides, you want to be successful making only on-target applications. It makes no sense why you wouldn’t.”
