ABSTRACT
Flufenacetplusmetribuzinplusatrazineis a new 75%dryflowableherbicidepremixdeveloped
by Bayer Corporation for soil-applied control of both grassy and broadleaf weeds in field com
grownforgrainorsilage. Thetradenameof this premixproductis AxiomAT. Eachunitof
Axiom AT contains 19.6 percent f1ufenacet, 4.9 percent metribuzin and 50.5 percent atrazine.
Axiom AT mixes well ineitherwaterorsprayablegradeliquidfertilizercarriers.Axiom AT can
