Peach borer (organic) prevention ideas
I've been getting peach borer pretty bad. It girdled off like half the circumference of a baby Winblo, and is now after one of my apricots.
I read up a bit on borer life cycle and control methods. Control methods summary I have read about:
-Using a metal wire (this is great)
-Digging out the surrounding dirt (this is great)
-Neem oil I saw somewhere listed as possibly effective??! That would be great if spraying the ground with neem did anything. But I have doubts on that. Any thoughts on this one?
-Nematodes (not sure efficacy... and sounds cumbersome not one and done...I think would have to keep adding more nematodes as needed every season or so around a bunch of trees...)
-White latex paint
-PDB crystals/Moth balls
-Heavier chemical sprays (don't really wanna go there)
Then I read this thread below from the organic forum and that got me thinking about mechanical prevention of invasion. This person suggests what seems to me a great idea. Basically just wrapping the base of the tree/underground a bit with cloth dipped in tangle foot. I think this would get the moths stuck trying to lay eggs on bark... And maybe the larvae will get stuck too if they try to enter the tree. It would still leave a bit of possibility of eggs laid in surrounding soil and also feeding on unprotected near surface roots--but I don't think that is the main worry. In either case, this sounds simple and pretty effective and just a couple mins added to the initial planting time for each susceptible tree.
I've never used Tanglefoot before but it is listed as organic in case that is a concern having non-organic stuff under soil near roots. I've used those long windy sticky paper mosquito traps. That stuff might break down underground or even over ground with rain...not really sure their durability... But some sort of wrapping with sticky stuff seems like a good idea. Maybe even planting a tree with those plastic tree guards to go a couple inches below the soil would help if it was really tightly bound to the trunk. Now that I think about it... how about just wrapping the bottom up with burlap? That should be woven fine enough to keep out the bugs too.
What do you guys think? It seems as though some sort of preventive method is in line for me, I can't bear to keep waiting for it to hit all my trees and then try to damage control.
