Granular bioherbicide was produced under contract for The Scotts Miracle-Gro Company, at a pilot scale manufacturing facility on grain using solid state fermentation. The experimental bioherbicide product supplied for this experiment had half the potency that will be delivered in the commercially produced batches, as such higher application rates were used to compensate in this study. To initiate the studies, plots were irrigated to dampen weed and turf foliage, and treatments were applied to the dampened foliage via shaker jar at application rates of 32, 64 or 128 g m 2. In 2011, treatments were split-applied, with half of the herbicide applied at trial initiation and half applied 28 days after treatment (DAT) For 2012, the same overall rate of herbicide was applied, but treatments were applied once at trial initiation. Granules were left on weed foliage for 24 hours, at which time granules were washed off of plant foliage and into the soil by irrigation
