The EPA announced last week that the agency is considering changes that would allow them to veto state restriction on pesticides that are more strict than federal rules.
Regulators in Arkansas voted to allow some use of the herbicide dicamba that was previously banned after complaints that it causes damage to nearby crops.
In much of the Midwest, state-mandated buffer zones, for certain pesticides near schools and waterways, don’t exist.
It's back-to-school in Indiana, and students at Benjamin Franklin Elementary might have a potato harvest to dig up after class.
Dicamba is suspected in the damage of tens of thousands of farm acres primarily in Arkansas, but also in southeast Missouri and in neighboring states.
Farmers use nearly 900 million pounds of pesticides every year. Sometimes those chemicals drift to neighboring property, which can ruin crops on organic farms.
Anthropologist Catherine Tucker brings us the perspective of coffee growers. S.K. Quigley roasts the beans. Daniel Orr uses coffee in a barbecue sauce.
Drift can happen with any weed killer. A stiff breeze can carry tiny droplets from the sprayer in one field to the vineyard next door.
