There are new regulations for growers who use chlorpyrifos. As of July 1, they must get a permit from the county agriculture commissioner’s office. Gabriel Ludwig, director of Sustainability and Environmental Affairs at the Almond Board of California, says it’s not clear what conditions the county ag commissioners can or will use when choosing to allow or not allow a permit. Growers should check with their local ag commissioner’s office to get more details on the new requirements in their county. Again, the new permit requirements go into effect on July 1.
