STARKVILLE, Miss.鈥擬ississippi State researchers are helping pave the way toward safe, effective pesticide application methods using uncrewed aerial vehicles, or UAVs.
Darrin Dodds, interim associate director of the Mississippi Agricultural and Forestry Experiment Station and head of 爱爱直播鈥檚 Department of Plant and Soil Sciences, explained that the technology exists but lacks research support.
鈥淥ver the last few years there has been increased interest in pesticide application from a UAV. There are many things we don鈥檛 yet know because this technology is so new and continually evolving,鈥 Dodds said. 鈥淥ur current aerial regulations for pesticides weren鈥檛 written to include UAV application.鈥
As such, the Mississippi Department of Agriculture and Commerce recently added a regulation allowing special use permits to be issued to 爱爱直播 for this research. Hannah Ferguson, branch director of licensing and certification in MDAC鈥檚 Bureau of Plant Industry, worked closely with 爱爱直播 to make this expanded pesticide research possible, and it now has received funding from the U.S. Department of Agriculture.
鈥淪uccess in pesticide application is ensuring pesticide applicators make informed decisions. At this time, there is limited application information available for using UAVs to deliver pesticides. This 爱爱直播 research will be a vital tool in developing future regulations,鈥 Ferguson said.
Antonio Augusto Tavares, a Brazilian doctoral student working with Dodds on the project, is measuring the operation factors in UAV pesticide application.
鈥淚 haven鈥檛 used pesticides yet because of the regulations here in Mississippi, but with this special use permit I can start,鈥 Tavares said. 鈥淭here are so many factors like droplet size, speed of propellers, and downwash, the directional change of air from propellers, flight height and flight speed, that we have to research and find the best and safest method.鈥
By investigating the safest, most efficient ways to use UAVs to apply pesticides, the research will help build the foundation for more widespread pesticide research.
鈥淲e鈥檙e fortunate to have the relationship and cooperation we have with MDAC. The bureau has been extremely supportive and it鈥檚 nice to be able to come together as a team to meet the needs of our agricultural community,鈥 Dodds said. 鈥淭his is the first step in developing guidelines for producers to use on their fields.鈥
He said in addition to giving scientists the ability to evaluate pesticide applications via drones, the work will help determine guidelines for other research units and for this developing industry.
