Thrips control on nectarines

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.
