Also it is my understanding that you mix it with 10 gal of water per pouch, and it covers 1/4 to 1/2 acre.
Per the product label for Dithiopyr 40 WSB, when using as a post emergent tank mix for crabgrass: Improved control may be seen by the addition of a nonionic surfactant. The rate will vary depending on the type of grass you have and program you are using.
