LB IN 3 PA COUNTIES Thursday, June 17, 2010 1:06 AM EDT The late blight is again attacking tomato plants in Somerset, Cambria and Blair counties. /// Here is a link that might be useful: LB in 3 PA counties

Gosh, I don't know. I would guess it would be. It's toxic, but not in a huge way, the lable says you can use it as a flea dust for pets, I wouldn't, but it says you can. I got mine at a hardware store and it's very common here in the US. If you prefer to go 100% natural, you can invest in some lady bugs, I've also heard of people putting a hose sprayer on with a bit of force and just hose them off repeatedly. Good luck!

I found the PA article interesting in that they mentioned it may be in the soil. This is the first I've heard it possible, unless they mean it overwintered on tubers or plant parts, though PA should have killing low temps. Usually only Early Blight can be soilborne and not Late Blight, I thought LB needs a living host.

My husband went through almost 3 years of these 'hives'. Called angioneurotic edema when a reason such as allegy isn't found. There was never more than a few days between 'attacks'. He had large swellings on every part of his body. (yes, that too) Sometmes it would be just a finger or an eye lid. Other times it would be in a half dozen or more places at once. More often than not he would have it around his waist at the belt line. Heat, cold and pressure seemed to set it off. The worst was when the condition went 'inside' and he would have what semed like severe indigestion and pain in the diaphragm/esopagus. About 3 years into this, he bagan having a different chest pain. It turned out to be angina and a short time later he had quadruple heart bypass surgery. Two days after the surgery, he had his last attack of these hives. It has been 23 years now and he has not had another hive. Were the hives and heart condition connected? I don't think so...but who knows. The propensity to angioneurotic edema, I have read, runs in families. Our daughter in her teens, had a round of it that ran for about a year. She is diabetic, and when she was changed from beef insulin to pork insulin the breakouts stopped. She is 46 now and has had no more problems. Daughter #2 has, over the last 10 years, had maybe 6 or 7 short episodes of it. And 3 of my husbands 6 siblings have had short episodes with it. The only thing that helped anyone was time. They just have to run their course it seems. Husband and daughter were put on a couple different medications, including benedryl, that did not help. Maybe now there is something that will. Do a web search for angioneurotic edema. There is a lot to learn. Much more now than when we were looking for answers for my husband and daughter.
