Apple diseases are best controlled before they appear. So it’s best to have an early-season apple disease management plan. This doesn’t need to be complicated. All you need are the basics: 1. What kind of trees do you have? 2. Did they show signs of disease last season? 3. Have you treated in the past? 4. What diseases are your trees most likely to develop? Asking yourself these kinds of questions will lead you in the right direction to manage your fruit trees and prevent many types of diseases.

Bonide™ Tree Fruit Spray or Spectracide Immunox™
