In years of heavy thrips populations, the choice of proper materials, including the more effective organic phosphates, and timing of applications are extremely important to avoid damage in nectarines. In a year of low thrips populations, and especially when the one-thrips-nymph-per-blossom level does not occur until late in the bloom period, choice of material and timing of applications are not as critical; and treatment may be unnecessary or of little economic value. This report summarizes four years of research in Kern County.
