IN | That’s what we typically blame it on and I would agree with that assessment but I think this year we’ve had 2-3 heat dome systems push far north into the Dakotas and even Canada and with them I think the spores and diseases floated aloft and came down with the rain. We’ve never had southern rust as a concern here and I just found a leaf the other day. The frontal boundaries that kick up all the dust in the atmosphere when the temps drop 15 degrees I think are responsible for it. Kicking up dust particles infected with disease spores way up 50-60k feet and hitting the jet stream at 200mph makes it way north a couple thousand miles pretty quickly. Then the rain brings all that down coupled with high temps and it’s like trying to keep a rope away from a mastiff | |
