Ok all I have post plus, I bought 2.5 gallons of it a couple years ago. I have used it to spray a half acre twice, with crop oil. I sprayed around 2 gallons, believe I followed the label that was 2oz per gallon and .5 oz per gallon of crop oil (whatever the label states it is something similar). I just havent been able to get a great grass kill - am I doing something wrong? Do I need to just use CLETH? Anyone else have this experience?
