Question:

I have a few young apple and stone fruit trees. Which pests and diseases should I spray proactively and which should wait until I see activity or damage?

Answer:

We have a website on spraying fruit trees.  

Insect Pests – Cooperative Extension: Tree Fruits

Pests that are problematic every year are these:

  • plum curculio
  • codling moth
  • apple maggot

Trunk borers are less a problem each year, but when they pop up, they kill trees.
