Abstract/Contents:"Crabgrass species (Digitaria spp.) are widespread annuals found on creeping bentgrass (Agrostis stolonifera L.) golf course putting greens. Pre-emergence herbicides are an effective technique for control of crabgrass, but tolerance of creeping bentgrass is a concern at putting green mowing heights (~3 mm). Newly developed, methiozolin is a cell wall biosynthesis inhibitor with strong activity as a pre-emergence herbicide for crabgrass. The objective of this research was to evaluate the use of methiozolin for control of crabgrass, duration of residual activity, and turfgrass tolerance. On April 6, prior to initial crabgrass emergence, a field trial was established on a creeping bentgrass putting green in Columbia, Missouri in 2012. Treatments included methiozolin at 0.5, 0.75 or 1.0 kg ai/ha as a single application or sequential applications. In addition, the pre-emergence herbicides bensulide, dithiopyr, indaziflam, bensulide + oxadiazon, and siduron were included as single or sequential applications, as well as an untreated control. Experimental design was a randomized complete block with four replications. Data collected included turfgrass quality, normalized difference vegetation index (NDVI), turfgrass phytotoxicity and percent crabgrass. All treatments, with the exception of siduron, reduced crabgrass density by >=60% compared to the untreated control 8 weeks after initial treatment (WAIT). By 21 WAIT, plots treated with bensulide, dithiopyr and two applications of methiozolin (1.0 kg ai/ha) resulted in 93, 94, and 90% crabgrass control, respectively. Only plots that received bensulide + oxadiazon showed transient phytotoxicity following application, but turf quality was not reduced below an acceptable level (<=6). Methiozolin appears to result in a level of crabgrass control similar to commercially available compounds, with no apparent injury to creeping bentgrass."
