Abstract/Contents:"Mesotrione is a HPPD-inhibiting herbicide that is used in Zea mays for broadleaf and grassy weed control. It has recently been researched for possible use in turfgrass. The objectives of this study were to compare various rates, formulations, combinations, and timings of mesotrione and other herbicides as selective controls of large crabgrass [Digitaria sanguinalis (L.) Scop.]. Studies were conducted at the Iowa State University Horticulture Research Station near Ames, IA over the 2006 and 2007 seasons. Treatments included granular and liquid formulations of mesotrione applied as a preemergence control alone and as a postemergence control alone, as a preemergence application followed by a postemergence application, and as combinations of mesotrione and prodiamine mixed onsite and as a prepackaged mix applied for both a preemergence and postemergence control. Granular mesotrione applied as a preemergence at 0.27 kg ai ha-1 did not reduce D. sanguinalis groundcover as compared to the nontreated control. Postemergence applications of mesotrione at the same level resulted in 27% control of D. Sanguinalis. Granular combinations of mesotrione and prodiamine provided an average of 91% control of D. Sanguinalis compared to the nontreated control. Liquid applications of mesotrione applied at 0.21 and 0.28 kg ai ha-1 as a preemergence controlled D. Sanguinalis an average of 38%, whereas postemergence applications at the same rates resulted in an average of 87% D. Sanguinalis control. Mesotrione applied at 0.28 kg ai ha-1 as a postemergence provided 94% control, which was equivalent to preemergence and postemergence applications of dithiopyr at 0.56 kg ai ha-1. Combinations of mesotrione and prodiamine as a prepackage mix compared to mixing the materials onsite provided equivalent control of D. Sanguinalis."
