Noticed a few days ago the tips missing on some of my Hallertau bines. Now there are leaves chewed off but none at the ground level so it isn't an animal (rabbit,etc.) doing the damage. I live in Michigan, lot of rain lately. I've been using Garden Guard, but every time it rains it washes off. Last couple of days have been high winds which blows the dust off as well. Didn't touch my first-year Fuggels that recently sprouted. Once the tip is chewed off, that bine is pretty much done for, correct? They were doing so well this year!
