Would Fertilome Tree and Shrub Systemic Insect Drench work well on evergreen shrubs and spider mites


Fertilome Tree and Shrub Systemic Insect Drench is not labeled for mites at all. Talstar works well for both the mature and the immature spider mites. Talstar provides optimal spider mite control when applied during spring to mid-summer. Higher application rates and/or more frequent treatments may be required for acceptable spider mite control during mid- to late-summer. The addition of a surfactant or horticultural oil may increase the effectiveness of Talstar. Talstar applications may be rotated with those of other products  that have different modes of action in control programs that are designed  to manage resistance by two-spotted spider mites. Consult your local Cooperative Extension Service for resistance management recommendations in your region.
