We do have various products that are labeled for thrips that can go to California. ImidaPro 4SC is a very good product that can be used as a basal trunk treatment. It is also labeled for certain edibles as well. If you would like another product that contains the active ingredient Dinotefuran, Zylam Liquid Systemic Insecticide would be a good choice and is labeled for thrips. Be sure to check the product label to be sure that it is labeled for your needs. It also comes in a soluble granule formulation, Zylam 20SG Systemic Turf Insecticide.
