California Pesticide Use Rises Despite New Rules

California's new regulations aimed at reducing cancer risk from the fumigant 1,3-D have not prevented a rise in its use. - Farmers applied one million more pounds of 1,3-D in 2025 than in 2023.

- Increases were highest in Kern and San Joaquin counties, used on almonds and grapes. - Air monitor in Delhi, Merced County, showed a 30% increase in 1,3-D levels.

- Critics say regulations fail; DPR attributes rise to replanting cycles. The state's pesticide regulator defends the rules but acknowledges more data is needed.
