I am a chemist and mixing chemical such as Negate is easily done. Negate killed weeds as advertised. However, there are multiple areas in my lawn with almost no growth mixed with brown grass. It's a dangerous herbicide that's not worth using. I purchased it to kill poa anna weeds.
left several bare spots and suppressed growth for several month's. Had a Peachtree in my backyard near my fence and applied one application several feet on opposite side of fence that killed my Peachtree. Although instructors stated not to apply near trees. My parents Anna was completely eradicated. I'm a chemist and mixed solution as instructed.
