Read the first part of this story: The human cost of Yuma’s vegetable empire
As the sun rises, patches of acreage come to life in the small yet bustling outskirts of Yuma. Tractors and crop vehicles are running, filling the air with noise. Thousands of workers set out to spray, test, thin and harvest thousands of pounds of crops.
Yuma County produces 90% of the nation’s lettuce during the winter months, a pace that growers say would be difficult to maintain without pesticides, even as organizations like Beyond Pesticides warn of their public health risks.

John Boelts co-owns and operates the family-run Desert Premium Farms, questions the scientific basis of those arguments.
“I feel very comfortable with the level of robust science and monitoring that goes into it,” said Boelts, who also leads the Arizona Farm Bureau. “I don’t put much faith in some of the pseudoscience out there that says this is bad or that’s bad.”
Pesticides – including herbicides and insecticides – protect crops and maximize yields during harvest.
Yuma County’s agricultural economy is a blend of large operations and smaller farms, like Desert Premium. Both use pesticides to stay on track for their harvest date, especially in seasons of inconsistent weather.
Over the past four months, Yuma has seen record rainfall, well above the 30-year average.
The constant rain has brought mildew into play, and Boelts said he relies on pesticides to mitigate its impact.
“It’s very challenging to understand that literally overnight, the crop that you’re growing, that you’re gonna depend on for food, could be eaten up by insects. It could be devastated by fungus that develops or is devastated by a disease,” Boelts said.
The Environmental Protection Agency and the Food and Drug Administration oversee pesticide monitoring. Boelts said his farm strictly adheres to the guidelines.
“People’s health and welfare are number one. When you have that mindset, the rest falls into place. … We’re training folks long before they ever see a pesticide. … We’re also never gonna use any pesticides that aren’t registered by EPA and have not gone through the proper course of inspection and approval for use,” Boelts said.
Each pesticide has a designated wait time before farm workers are allowed back on the sprayed field.
“We have to use suits, masks, gloves, carbon filters on the tractors so that the smell doesn’t pass through, and yes, we can have training when something happens, like washing our hands, our face, our body,” said Francisco Javier Morales Alvarado, a Desert Premium farmworker.
Each time Desert Premium plans pesticide application, workers consult a pest control advisor.
“It’s heavily regulated pesticides, and we’re only able to get them through the PCA (pest control advisor),” said Andres Elizarraras, the spray foreman at Desert Premium Farms. “If we’re gonna have them (spray), we make sure they’re not gonna be harvesting within those days.”

On Boelts’ farm, tucked away behind a large bulletin board, a thick yellow book called the Pesticide Application Records documents every instance of pesticide use.
“We fill out what’s called a 1080 form. Once we complete it, we turn it into the state and have a record of what time, in case someone does get sick, we can go back and see the times that we sprayed them,” Elizarraras said.
For Boelts, keeping people safe comes down to following regulations designed to minimize the impact of necessary pesticide use.
“What we’re trying to accomplish out here is produce people’s food and fiber and do it in the most ecologically, environmentally and responsible way possible,” Boelts said.
