Limb Damage Due To A Heavy Crop Load. Too much fruit on a single limb and the weight can cause the limb to separate from the trunk. We get it at the orchard if we do not thin the fruit enough on the limb or if the limb has a poor attachment to the trunk. Make sure that limbs which support fruit are attached to the trunk at about a 45 degree angle. Peaches should be thinned so that the fruit is about 4 to 6 inches apart along the limb. Summer pruning, talked about here on this blog, will help to keep fruit loads more manageable and cause less damage to the tree. During summer pruning, usually around April and May, excessively long branches on peaches and nectarines are pruned back so they are no longer than about 18 inches. This helps to distribute the crop load for the next year which is born on the wood which is produced this year.

Wormy Peaches, Nectarines And Even Almonds. Peach twig borer in the adult stage is a brown month about 1/2 inch long. After eggs are laid by the adult moths, worms or larva enter soft fruit usually near the stem end. When they enter near the stem end they leave behind some brown excrement that looks a little bit like wet, dark brown would grindings.

It is important to get these insects under control very early in the season. There can be several generations each growing season and their numbers are not additive but multiply at very high rates so their numbers increase rapidly.

We use pheromone traps to begin to identifying when they are flying and add a very high density so that we get some mating disruption. Then we usually use either sprays of Bt or spinosad.
