Protecting fruit trees from diseases and insect pests is an essential part in maintaining a healthy and productive orchard. One of the most impactful diseases apple growers need to manage is the fungal disease Apple Scab, Venturia inaequalis. Growers typically use fungicide application as the primary method of apple scab management. In addition to managing apple scab, growers need to manage environmental conditions affecting their fungicide application. This study evaluated the rainfastness of certain fungicides and the addition of a sticker adjuvant and their efficacy after wash off after four levels of simulated rainfall (0, 6.3, 12.7, 25.4mm). The rainfast properties were analyzed based on recovered residue data, and the efficacy was measured by shoot count infection counts after infield infection simulation. This data will contribute data to spray management programs in order to manage apple scab.One of the most impactful pests pear growers need to manage is pear psylla, Cacopsylla pyricola Forster (Hemiptera: Psyllidae). This study tested two biopesticides as foliar application and trunk injected application methods to evaluate the efficacy of trunk injected application. Insect control was measured by egg and nymph counts. The results of this study contribute to the practice of trunk injections as a method of pesticide application as well as the efficacy of biopesticides and their development into modern pest management programs.
