| Abstract/Contents: | "Field and greenhouse studies were conducted in New York and Virginia to evaluate the possible effect of landscape mulch types and placement on the efficacy of the preemergence herbicide pendimethalin. The two sprayable formulations evaluated (3.3 EC and 3.8 CS) were applied at 2 lb/A (ai) throughout the study. In New York, five much types were applied to bare ground at a two-inch thickness on May 24, 2004. The mulches were pine needles, shredded pine bark, pine bark nuggets, shredded hardwood and cocoa hulls. The pendimethalin formulations were applied over the mulches and smooth crabgrass (Digitaria ischaemum) and redroot pigweed (Amaranthus retroflexus) seeded over the herbicide treatments and mulches and irrigated. The results of visual evaluations indicate that both formulations provided eqyally excellent control of these species for 60 days after treatment. No interaction was observed between any of the mulches and pendimethalin formulations. In Virginia, both formulations were applied either over or under a two-inch layer of pine bark mulch. In this study, large crabgrass and yellow foxtail were evaluated for the level of control up to 57 days after treatment. The results indicate that both formulations at either placement, relative to the mulch, controlled both species equally well. In the absence of mulch, the CS formulation appeared to provide a slightly higher lever of control than the EC. In the greenhouse, in Virginia, seven types of mulch were evaluated: pine bark, pine bark nuggets, shredded cypress, shredded cedar, shredded hardwood, red-dyed mulch and particularized rubber mulch. The results of weed counts 12 days after treatment indicate that in general, the CS formulation allowed more crabgrass to emerge through all the mulches than the EC did. However, by the 23rd day after treatment, this difference had been reduced to insignificance for all but the rubber mulch, which continued to allow for more emergence in the CS treated flats. The results of the field studies indicate that either formulation of pendimethalin in concert with a variety of mulch types can provide excellent control of certain summer annual weeds for up to 60 days after treatment." |
