The latest updates to the Irrigated Lands Regulatory Program, known as Ag Order 4.0, will impact how Central Coast growers manage insecticides and other contaminants to protect surface water. To support growers in meeting these new requirements, the Coalition for Urban Rural Environmental Stewardship (CURES) has released a video titled “Innovations in Managing Farm Runoff and Insecticides.” 

Here’s a snapshot of what the video covers: 

• Polyacrylamide (PAM) Usage: PAM acts as a flocculant to remove silt from drain water, ensuring it stays within the field and doesn’t pollute nearby water bodies. 

• Biochar Flumes: This innovative device directs field drain flows through containers filled with biochar, which helps filter out contaminants. 

• Sprinkler Irrigation Management: Techniques are discussed to optimize irrigation and reduce runoff, which can carry insecticides into surface waters. 

• Drift Management: The video provides guidance on minimizing spray drift during pesticide applications, especially near waterways, to prevent contamination. 

With water regulators closely monitoring runoff and the potential for stricter regulations, it’s crucial for growers to explore and implement these best practices.
