| Abstract: | The conidial deposition of BotaniGard® 22WP on chrysanthemum plants was assessed. Assessments were conducted on stationary and moving applications using different spray nozzles, application angles and tank pressures. In addition, the spray time and distance from the target plant were included. Conidial deposition was greater on the upper canopy of the plants and the upper sides of the leaves. The nozzle type, spray angle, and distance from the target plant had the most significant effects on conidial distribution. The optimal spray nozzles were found to be HC-22 and FAN-1, which provided the best coverage of both the plants in general, and on the lower surfaces of the leaves. |
