4 weeks of protection?
The bottle of permethrin (its older/Bug B Gone) says it gives 4 weeks of protection on the cover. Is this even possible? I'm 2 weeks out from spraying and so far, no damage that I can tell on the plums or apricots. The unsprayed apples got hit good (PC) as did one sweet cherry (probably picked off 50 cherries that were hit). The peaches look fine, but PC have never hit the peaches hard in my yard. We've had almost 3 inches of rain since I sprayed.
I'd love to go as long as possible between sprays, but I think I'm pushing my luck. Anyone else ever figure how long you can go between sprays before damage starts to occur?
