The California Department of Food and Agriculture has changed the guidelines for using imidacloprid as a foliar treatment prior to harvesting and transporting bulk citrus fruit. With the University of California, Integrated Pest Management Program’s approval, citrus growers and PCAs can use any 4F formulation of imidacloprid at a rate of 8 oz. and any 4.6F formulation of imidacloprid at a rate of 7 oz. to comply with the spray and harvest option for moving bulk citrus fruit.
