that is true about 2,4-D volatility. be careful. avoid drift.
but the reason i am recommending cim. max is the fact that 2,4-D amine by itself has no residual, while weedmaster does. you can get around 30 days residual control. this will give you the fast knockdown that you want that straight cimarron plus cannot give. then with the 2 of them working together, it has a broader spectrum of weed control, plus they have a synergizing effect with one another. it is a good buy price wise for the cim max. you cannot go buy generic weedmaster and cimarron plus separately and hardly come out better on price than cimarron max.
i have some to sell if you want. that is what i do, sell ag chemicals. hit me up 979-272-8470
