Growing Together Winter 2020

Crop Protection Products Coming to California

Matt Ehlhardt, Grow West Director of Technical Services

To register a crop protection product in California takes time (generally two or more years after the EPA has granted a registration) and money (in addition to the fees for registration some-times extra costly research is required).  New products for our growers come at a very slow pace. Having said that, in the next one to two years we will be receiving several products that are going to help California growers in their efforts to control diseases, insects and weeds making their job easier and hopefully more profitable.

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 in order to mitigate the development of resistance to a mode of action. When a “U” is stated it indicates that the mode of action is unknown at this time.
