Over the past several months, I have been paying close attention to the growing conversation surrounding paraquat in California. In my opinion, this issue is about much more than one product or one regulatory review. It is a preview of where California agriculture is headed overall when it comes to regulation, transparency, public pressure, and operational risk.
The pressure around pesticides is clearly increasing. California’s Department of Pesticide Regulation officially began reevaluating paraquat under AB 1963, legislation requiring DPR to review the pesticide’s potential health and environmental impacts and determine whether restrictions, suspension, or cancellation may be necessary by Jan. 1, 2029. Then in April 2026, Syngenta voluntarily canceled the California registration for Gramoxone SL 3.0, one of the most recognized paraquat products on the market. As of May 2026, other paraquat products remain registered in California and are still under reevaluation by DPR.
Now to be clear, this does not mean all paraquat products disappear overnight. But it absolutely sends a message to the industry that the regulatory environment surrounding crop protection tools in California continues to tighten.
At the same time, systems like California’s SprayDays notification platform are creating a much more transparent operating environment. The public now has greater visibility into restricted material applications through online maps, text alerts, and email notifications. Whether the industry likes it or not, agriculture is operating in an environment where applications, stewardship, and public perception are becoming more visible than ever before.

The Industry Must Adapt
What stands out to me most is how much the role of the PCA has evolved. Today’s crop consultant is no longer simply making agronomic recommendations. Modern consultants are increasingly helping growers manage compliance, stewardship, documentation, resistance management, operational liability, and even public perception. That is a major shift from where the industry was even 10 years ago.
In my opinion, the consultants who recognize this shift early are going to become incredibly valuable moving forward.
One of the biggest mistakes any operation can make right now is becoming overly dependent on one chemistry, one tool, or one regulatory assumption. California agriculture has seen this movie before. The smartest operations are already evaluating rotational programs, alternative chemistries, precision applications, mechanical strategies, and broader resistance management systems before they are forced to react under pressure.
