Apple scab. While the use of aerial application is quite satisfactory for the control of apple scab when fungicides that may be re-distributed by rain are used in a protective program, its use for eradicant control poses a risk for disease development. The aerial label rate per acre for dodine (Syllit) is too low for good eradicant action Washington State University Cooperative Extension Intergrated Pest Management is the best management strategy for many pests. It takes a lot more home work to evaluate the pests and the control strategies. Monitoring is very important.
