A True Doomsday Prepper
My plums are just starting to bloom. Last year the squirrels had a feast and the year before, each plum had a tiny white worm in it.
That worm is a fruit maggot laid by a small moth that lays eggs on the emerging leaves, blossoms etc. The eggs hatch and the small worm makes it's way to your fruit. Dormant oil sprayed once or twice while the tree is dormant will help to kill anything overwintering on the bark or around the drip line of the tree. Then I spray every 2 weeks or so with Neem oil or Bt (Bacillus Thuringiensis) both approved organic. Bt kills caterpillars and will also help with borers which are a huge problem in TN. Neem will kill caterpillars and has the additional bonus or helping with fungal outbreaks. I spray when bees are at their least active late in the evening. You can also use Pyrethrins which are made from chrysanthemums and is also considered a low toxicity pesticide. Unfortunately it is difficult to grow stone fruit in Tn without some sort of spraying without insect damage of some sort. My fruit trees are one of the only crops I spray.
