flufenacet + metribuzin (Axiom DF)
Idaho and Washington, and Oregon except for Jefferson County
Rate 0.267 to 0.31 lb ai/A flufenacet + 0.067 to 0.85 lb ai/A metribuzin (8 to 10 oz/A Axiom)
Time Apply before weeds emerge or no later than the two-leaf stage of volunteer grasses. Applications after mid-November may result in crop injury and/or poor weed control.
Remarks For established Timothy seed fields only (at least 1 year old or after first seed or hay harvest). Excessive straw on field may reduce weed control. Rain or irrigation after application is needed for sufficient weed control.
Caution Do not apply in tank-mixtures with diuron or postemergence herbicides. Do not apply to soils with less than 1.0% organic matter or to soils with a pH greater than 7.5 or severe crop injury may occur. Do not allow animals to graze treated fields following application. Preharvest interval is 120 days. Do not apply more than once per year.
