Do many of you have issues w/ it? It's an issue w/ pine stumps. The state forest requires treating cut stumps on logging of pines in my area, unfortunately most private timber sales aren't willing to pay for it. Today's mechanized harvesters are set up to auto spray stumps after cutting, but it's an added cost...but it's also a growing concern. It's a damaging fungus. Hopefully it's not in your area.

It’s a problem in WI but has been documented only once or twice in MN. Turns out there is a predatory fungus that feeds on Heterobasidion and it is much more common over here. At least, that is what the initial research indicates. So we haven’t had to deal with it.
I have heard about some loggers getting set up with spray equipment on their processor head. Sounds like a slick way to do it. I can see it being a cost up front and it takes an extra second or two on each tree. Last I heard you could use a mixture of water and borax to spray the stumps and that is a pretty cheap solution.
If you have pine that needs to be thinned you can go out and spray the stumps with borax. It’s best to do it every day while they are harvesting but the solution is pretty painless.

Interesting, does only affect pine trees? The models say if it jumps to humans it could kill 250 Million people!

I meant this to be a serious post, as it isn't a joke here in Wi.
run, to my knowledge it pertains to pine trees.
As long as the stumps are treated within a certain period of time (i think like a day) it won't spread.

Thanks for the gr8 post. Very interesting to have your personal insight. I knew it was a pain but I didn't know all those details. The trouble I have around here is many people are rather recklace on private jobs.

If you leave the stumps untreated, will we experience another Bath tissue shortage? Just curious and nosy.

Well, it makes it much easier for the problem to spread if stumps aren't treated, so theoretically I would say it could.

I was cutting a survey line last weekend. I used the 20 Mule Team borax option. I just sprinkled it on the stumps. It's not technically 1 of the 2 options WDNR seems to recommend, but I seem to hear that it's worth trying the borax option, so I gues that's how I'll do it. Hopefully it works. It can be bought, cheap, at the grocery store. The rot is within 25 miles of me, and there's no cure for it once/if it hits your property. Unfortunately many do no treatment. I thought I heard small stumps don't need the treatment, but I guess I'd probably err on the safe side and treat all the pine stumps.

I'm thinking I should consider mixing borax w/ h20 in a squirt bottle rather than shaking it on the stump as a powder
