How to Use Insecticides on Plum Trees
The fruit of plum trees, just like that of many other fruit trees, can be invaded by a variety of pests. The most common pest of the plum tree is the plum curculio. They are easily identified by looking at your plum pits and seeing if there are worms inside. Mites are known to attack the tree leaves turning them brown and preventing photosynthesis. Borers, on the other hand, attack the tree trunk. The key to getting rid of these pests is to identify which pest you have and use insecticides on your plum trees. Does this Spark an idea?

Tips & Warnings
Don't spray any insecticide when the bees are pollinating the blossoms. The product will kill the bees and significantly lower your fruit crop.
If spraying a horticultural oil and insecticide read the labels thoroughly to ensure that the two are compatible.
