apple tree problem
Posted by kim from nv on 2002-03-06 15:23:30

I have 2 apple trees that I planted last year. They both have an area on the trunk where it looks like something has chewed into the wood. The wood looks almost dusty, flaky, and cardboard-ish (inside the hole). The tree has just bloomed, and otherwise looks fine. Does anyone have any suggestions? They are very small trees, maybe 2 1/2 inches in diameter. Any suggestions would be greatly appreciated!

    If these are near the soil line they may be Roundheaded Appletree borers. You can reach the larva by inserting a thin, flexible wire in the hole to spear the larva or there are parasitic nematodes that can be purchased (probably not cost effective for 2 trees) from a number of places.

        whoops... they aren't exactly near the bottom. they're actually in the middle of the trunk (but the trunk is only about a foot and half tall. i had heard of borers. do you think it would be a bad idea to paint the tree with latex paint. i'd read that it might help. i'm just not sure if it works, after the pest is already in the tree!?

          These then may well be the Flatheaded Appletree Borer, one of the pests not directly referenced in any of my books at the Apple entry but found on a general search for something else. Supposedly painting the trunk with a dilute solution of white latex paint (50 percent paint/50 percent water) will help.
