To register a crop protection product in California takes time and money. New products for our growers come at a very slow pace. Having said that, below are some products we anticipate or have recently received approval for use in California. The resistance management group that the individual compounds have been assigned to has been added for each product. It is important to know these when planning a pest management program to mitigate the development of resistance to a mode of action. When a “U” is stated, it indicates that the mode of action is currently unknown.
