It will take some math to figure out this mix if you're not spraying this out of an airplane,... but when you get it right you'll find that this stuff will last you over 6 years on a small lawn, and control weeds better than MSMA used to!!! I love this stuff! It's like a slow acting MSMA, and when mixed with 2,4-d theres literally not a weed it won't kill post or pre emergent! Careful around trees and shrubs as this stuff is lethal to them.
I live in an area plagued by bluestem. In unimproved pastures the grass is ok though some cattleman say that doesn't have a lot of nutrition. In other areas it is a complete pest. I have now sprayed Pastora twice following label directions for bluestem. The bluestem is dying and both Bermuda and buffalo grass are doing fine.
