Spray Programs

Posted by John Fulton -

For most of your fruit trees and also your crabapples, spray programs should have begun when the leaf buds started to open. According to the pest control handbook, sprays should continue on about a 10 day schedule until within 2 weeks of harvest for fruits, and until fruit set on crabapples. For the homeowner, a multipurpose fruit spray is the easiest product to use (it contains 2 insecticides and a fungicide). Just remember to avoid spraying insecticides on flowering plants because of toxicity to bees (like right now on apples.) You can substitute plain captan fungicide during flowering to continue your disease control.

Keep in mind that these types of sprays are preventative in nature. That means that you need to have the sprays in place before you have problems. Once problems appear, there is very little that can be done.

If you want more information on spray programs, feel free to stop by the office and pick up a copy of the "Home Fruit Pest Control" publication that is available at no charge. While the insecticides have changed, the timing has not.
