The pre=emergent that I used last fall did not do the job so it is hard to tell if the Barricade is working. I don't think that anything new is coming out but I am going to have to use a post emergent on poa anna and henbit that are all over the place.
I wouldn’t recommend this product compared to the promate granular barricade. I put down 4.0 lbs per 1000sqft on my zoysia lawn in late winter this year and I’ve had more weeds than ever. This will be my last time using this brand. I don’t know what the hype is over “The Anderson’s” products.
