Pests can spread problems quickly over a singe tree or throughput an entire orchard of healthy apple fruit producers. There are few maintenance procedures to follow the apple trees growing season to keep disease spreading bugs. Before new leaves emerge in spring, spray the apple tree with non toxic horticultural oil that will smother the dormant insects along with their clusters of minuscule eggs.
Around early to mid-summer is a prime bug breading season and this is also the best time to control the insects with organic insecticides to stop them from mating and laying eggs on or near the budding fruit. Pests that attack apple trees and damage fruit and leaves contain the codling moth, maggot flies.
