Man I busted balls today and sprayed a bunch of lawns. I used Speedzone and a sticker. The lable says that it is rainfast in 3 hours. OK I got 4 out of a couple smaller ones and the bigger ones had about 9-10 hours but now it is raining and it will rain for the next 2 days. I am sure the spray dried on all of them because it was a sunny day and about 62 degrees. Do you think I screwed up by spraying? I am way behind and I am hoping that this stuff lives up to its label. Oh ya we are supposed to get about 2 inches of rain in the next two days. The weeds are in cool season grasses, thistle, dandelion, spurge, clover. Tell me what ya think.
