From Best Buy Toy to Pro Spray Drone: A Father-Son Duo Takes Flight In Missouri Cattle Country

Wed, 15 Oct 2025 19:41:26 GMT

Iowa State University freshman Rhett Keaton and his father, Vance, are launching a drone spraying side hustle.

The father-son duo started out just having some fun several years ago, buzzing around the house with a $20 drone from Best Buy that “drove mom crazy”. But now, they are getting serious about turning entertainment to revenue.

Vance, who runs 5K Cattle Company out of Anderson, Mo., ran out and purchased a DJI Agras T20P spray drone this spring, and both Keatons secured the Part 107 Commercial Pilot Certificate needed to operate on a farm. Combined with the private pesticide applicator’s license 5K Cattle Co. already held, the guys can now apply restricted-use pesticides to their own pasture ground.

University of Missouri Extension experts recently weighed in on the promise of drone usage in farming, and more specifically, in cattle operations. Field specialist Caleb O’Neal likens the technologies’ versatility and practicality to that of a UTV.

“Back in the 1980s, it would have been rare to see a UTV being used on a farm,” he says. “Visiting farms today, I’m hard-pressed to find an operation larger than 20 acres that doesn’t have some type of UTV that they utilize on a regular basis.”

And while the Keaton’s are banking on custom application services with a spray drone as their next play in ag, you don’t have to spray crops or weeds to use drones for the benefit of your farm or ranch, according to O’Neal.

“Livestock producers can monitor fences and availability of water and can make sure animals are where they should be without even opening a gate,” O’Neal explains. “Drone technology lets cattlemen quickly check estrus indication patches for optimized breeding timing, monitor cows during calving season, look for hidden newborn calves and look out for potential predators.

Getting back to the Keatons, the next step is for Rhett, who is majoring in ag systems technology in Ames this fall, to secure his Missouri commercial pesticide applicators license.

Once that happens, the pair can start marketing drone spraying services to neighboring farms. Their plan is to start locally with pasture and grassland applications before seeking out work on row crop farms to the north once foliar fungicide season hits.

Even though the T20P is one of the smaller spray drones offered by DJI, Keaton says it’s proven to be the perfect fit so far. He also rents a neighbor’s spray drone, paying a per-acre fee, when he needs more than one bird to cover more ground.

“We do a lot of flying in and out of trees and stuff like that,” Keaton says. “Having that smaller drone with less capacity and a more efficient battery, I get about double the battery life as [the bigger drones] do. But I also have about half the tank.”

The reservoir on the T20P holds about 5.5 to 6 gallons of tank mix, so Keaton will usually need to land and refill his tank after about five or six minutes of spraying. He averages 23 acres per hour when everything is set up for a quick land-refill-takeoff cycle.

Keaton says Corteva’s DuraCor herbicide, an aerial application-approved formulation containing two Group 4 AIs, is the main product he’s been spraying from the drone thus far. The product label calls for 2 to 3 gallons of active ingredients (mixed with carrier water) applied per acre with coarse droplets.

Keaton and Vance also picked up a nicely appointed spray drone trailer off — of all places — Facebook Marketplace. The whole setup – drone, trailer, extra batteries, etc. – cost about $30,000 all-in, Keaton says.

“We found one that was cheaper to buy than it was to build our own, especially with the generator — that is probably the most expensive part of that trailer,” he explains. “It already had the generator, pumps, the mix tanks and a thousand-gallon freshwater tank, and everything was lined up.”

With the spray drone in the air and the nice, shiny trailer parked edge-of-field as Keaton makes his passes, cleaning up weed escapes in fields that he says are “pretty clean” already, neighboring farmers often take notice and stop by to ask if he and his dad can come by and spray some of their ground, too. Their plan is to find the sweet spot between a $12 to $20 per acre fee to charge for their drone spraying services.

Speaking of sweet spots, O’Neal feels that spot spraying, guided by aerial imagery or even first-hand producer knowledge of where weed problems are significant and need to be addressed, is a good target for drone service providers like the Keatons.

“A pasture with a rash of blackberry weeds in isolated areas has great potential for a prescription herbicide application where only the problematic areas receive treatment via a spray drone, as opposed to a broadcast application where the entirety of the field is treated whether it needs it or not,” he says.

“I think there’s a lot of opportunity [for it] around us. There’s a lot of guys with hay fields, and they do a lot of burn down applications. That’s one thing we are planning on hitting on,” Keaton says. “I think some guys would be interested in that. Especially if we have a wet spring and guys can’t get in the field.”

Missouri Extension field specialist O’Neal agrees with that assertion.

“In my neck of the woods in southwestern Missouri, the topography can be quite unforgiving, with some areas too harsh to allow access by ground spray rig or even an ATV,” O’Neal says. “With an aerial piece of equipment like a utility drone, landowners can now get herbicide applications on these problematic areas and put them into useful forage production.”

With a pilot year of flying his family’s acres fastened securely under his belt, Keaton says the arrow looks to be pointing up on spray drone technology in agriculture.

“Hopefully we can expand and get maybe another trailer or a bigger drone, it just depends kind of on what’s calling for us,” he says. “I’ve got to see exactly how much work is out there in this business and from there just make it all work out. Our foot is just in the door [right now].”

Why You Need to Pay Attention Now to EPA’s Proposed Rodenticide Mitigation Measures

Fri, 27 Sep 2024 01:18:52 GMT

Out of sight, out of mind. That theory works for a while until it doesn’t, especially when it comes to rodent control.

“Rodenticide use is like using insecticides. If you don’t see any cockroaches, you don’t worry about them. But once you see one, you throw the bomb at it,” says Larry Delozier, director of national poultry account sales for QC Supply.

Similarly, once you see a mouse or rat, it’s likely you have a big problem on your hands , explains Steve Von Haden, Midwest business manager for Motomco.

“Always assume you have rodents, and you should be putting bait out,” Von Haden says. “All agricultural buildings or structures will have rodents of some type. You just don’t want it to get to such high peaks it causes structural damage, diseases and contamination of food sources .”

Pending regulation could mean agriculture loses critically important tools to protect food security. EPA is proposing significant changes to rodenticides that would result in the canceling of products and uses, add more requirements to the labels, and reclassify some products to restricted use pesticides .

“Regardless of whether you are a livestock producer or citrus grower or manager of a golf course, this will have an impact on your ability to effectively manage a destructive farm pest,” says John Walt Boatright, director of government affairs at American Farm Bureau Federation (AFBF). “It’s one more challenge in a regulatory environment where challenges continue to grow for the American producer.”

What is EPA Proposing?

On Nov. 29, 2022, the EPA released for public comment new proposed mitigation measures for 11 rodenticides, which if implemented, will have a major impact on all currently available rodenticide products, the Agricultural Retailers Association (ARA) said on its website . The agency’s proposals are the most significant changes to rodenticides in 15 years that will result in the canceling of products and uses, add more requirements to the labels, and reclassify some products to restricted use pesticides, ARA noted.

EPA’s recommended changes are included in four Proposed Interim Decision documents (PIDs) that cover: 1) the seven anticoagulant rodenticides; 2) bromethalin and cholecalciferol; 3) strychnine; and 4) zinc phosphide.

“EPA’s proposal is quite wide-ranging, and it is going to impact any user of rodenticides and how rodenticides are applied,” Boatright explains. “The challenge is many of EPA’s proposed mitigation measures introduce additional challenges for on-farm application. I don’t know that they will have the intended effect that EPA thinks they’ll have.”

Boatright says this should be very concerning for everyone in the agricultural supply chain who apply rodenticides. Michael Formica, chief legal strategist for the National Pork Producers Council (NPPC), says it will also have a negative impact in urban areas where rodent infestation is a major problem.

“This is an example of one area where rural communities can build positive engagement and cooperate with urban communities. As much as rats and rodents are pests on the farm, they are even more so in an urban area,” Formica says. “In the back alleys in DC, you see rats that look like cats racing from one building to another, running around at night. People don’t want to live with them.”

And they shouldn’t have to, Delozier says. Rodent control companies have made effective, safe bait under EPA’s existing stringent restrictions. EPA’s proposed measures will add great cost and will likely be prohibitive for many.

What Does This Mean for Farmers?

If this proposal is enacted, rodenticide users will see many new restrictions.

“The average livestock farmer wouldn’t be able to use them, you would have to go through certification and training in your state,” Formica explains. “If you’ve got a row crop or grain operation, a lot of folks have that certification because they spray pesticides. But most livestock farmers don’t have all those different certifications.”

Certifications would be required annually, which takes a lot of time, paperwork and training.

“If you don’t have that certification, you would need to hire exterminators to come out. That’s expensive and creates its own biosecurity problem because you’re having people come out not just to apply the rat poison, but also pick up the dead rats,” Formica says.

Pick up dead rats? Yes, that’s part of the new measures, too.

“The proposal talks about mandatory carcass searches in the field. That seems to be quite a challenge to expect a farmer or a farm worker to stop what they’re doing and search for rodent carcasses in potentially hundreds or thousands of acres,” Boatright says.

Once the rodent carcasses are found, farmers would be required to not just log them, but also pick them up and dispose of them.

Another limitation of these measures includes the requirement of single-use base stations, which would create a lot of garbage, Formica adds. The bait stations being used today are refillable.

What Will Happen if Rodent Bait Goes Off the Shelves?

“The more regulation you put on farmers, the more resistance you will have and that’s not conducive to the economic engine that is farming and food in the U.S.,” says Mike Slegl, vice president of product sales for QC Supply.

Farmers aren’t misusing product with the intent of controlling other things, Slegl adds. Some believe EPA is rushing to do this because of pressure from environmentalists for Endangered Species Act concerns.

“There is a potential major negative impact of an additional EPA regulation on the true sustainability of livestock production and the livelihood of farms,” Slegl says. “If it’s one more forced hand that overnight becomes more expensive to something they’re already doing, there’s going to be major resistance and people will push towards non-compliance.”

Delozier fears EPA’s rodenticide mitigation measures will ultimately increase the cost of goods to the consumer.

“Whenever we add requirements, there is always a cost that goes into the food system and will eventually cost the consumer more, too,” Delozier says. “Farmers are already using rodenticides that have to be EPA-approved.”

Darrin Karcher, a poultry specialist and associate professor at Purdue University, says it could be a double-edged sword.

“With the larger integrated companies, if they have to pay someone else to do it, they will pay someone because it has to be taken care of. Where it may catch are those individuals doing it themselves who may not have financial depths to pursue having other people take care of application,” Karcher says. “The question becomes, can they find a way to do that?”

An Increased Biosecurity Risk

And what if they can’t? Rodents present a major biosecurity risk for farms. With devastating diseases like Highly Pathogenic Avian Influenza (HPAI) in the poultry industry and the threat of deadly foreign animal diseases like African swine fever (ASF) in the pork industry, leaders fear how this could impact the health of the nation’s livestock herds.

“The restricted-use pesticide designation concerns me,” says Matthew Galloway, Midwest sales manager for ag rodenticides with Liphatech Inc. “For the broiler and breeder side of the poultry industry, there are hundreds of thousands of barns all over the U.S. One contract grower often has four or five barns and there may be several thousand barns within each company. If farmers don’t get their license, they will have to hire an outside applicator. Then you run into the risk of biosecurity breaches. We can’t have applicators running through multiple farms over a week’s time, otherwise we’ll really see a massive problem.”

It’s also a major problem if rodents get out of control because farms can’t afford the added cost.

“You can put all the filters you want on the ventilation systems in your barns and be as biosecure of a facility as possible, but if rats can get in and out, they will find a way. They aren’t showering,” Formica says.

What Can You Do?

Every 15 years, pesticides are reviewed by EPA. This rodenticide review is part of a pilot project for EPA as they’re implementing their Endangered Species Act work plan. These mitigation measures seek to achieve compliance with their statutory directives at EPA, following recent court cases directing EPA.

“We will see this approach in reviewing other pesticides as well. Folks need to be prepared to provide input,” he says.

This is a proposed interim decision, Boatright explains. EPA will take comments through Feb. 13 and review them. They will then promulgate a final rule at some point in the future.

“Make your voice heard,” Liphatech’s Galloway says. “We’ve got to do everything we can. Submit comments to EPA.”

Both NPPC and AFBF are gathering feedback and information from its members and will be submitting comments to EPA by the Feb. 13 deadline.

“Weigh in and let elected officials know you value these products. The best thing you can do is call your member of Congress. We’re just coming out of three years of COVID, and there are tremendous human health issues of taking rodenticides off the market,” NPPC’s Formica says.
