Somewhat early for review as this is pre-emergence herbicide and I am looking for several months of residual control. It was not that messy to mix. I really liked the WG formulation measuring and mixing characteristics. I tank mixed with glyphosate and there was no problem with antagonism as the glyphosate gave good control. Got 2 inches of rain 48hrs post application, and to date no negative consequences noticeable. If it gives 6-8 months residual control, I'll give it 5 stars.
Purchased online on a Thursday and received on Sunday! Will use this spring (Late January in Central FL) as my pre-emergent. Took advantage of the 10% off Fall sale. Good deal. Expect to be effective based on other reviews of this product and active chemical, prodiamine, in general.
