| Abstract/Contents: | "An experiment was conducted at University Park, PA to evaluate the control of smooth crabgrass (Digitaria ischaemum(Schreb.)Muhl.) from subsequent year, reduced rate applications of selected preemergence herbicides. The experiment was conducted on a 7 year old stand of perennial ryegrass (Lolium perenne L.) maintained at 4.5 cm. In 1989 treatments were arranged in a randomized complete block design with three replications, and in 1990, treatments were arranged in a split block design with three replications. Treatments were applied at the label rate to the entire plot on April 27, 1989. On April 23, 1990, treatments were applied at label rates to half of the blocks and at one-half of the label rates to the other half of the blocks. Sprayable treatments were applied with a CO [subscript]2 powered boom sprayer, delivering 701 l/ha with 6504 nozzles. Granular treatments were combined with sand and applied with a shaker jar. Commercially acceptable was considered to be 80% or greater. All of the 1989 treatments provided acceptable contol [control], with the exception of benefin 60DF and benefin 2.5G. Of the full rate treatments in 1990, only DCPA 5G and benefin 2.5G did not provide acceptable cotrol [control]. Those same treatments did not provide acceptable control at half rates, along with DCPA 6F, bensulide 4E, prodiamine 65 WDG, pendimethalin 60WDG, benefin 65DF, dithiopyr 1EC, and Team. It appears that acceptable control of smooth crabgrass can be achieved with reduced rates of some preemegence [preemergence] herbicides, following an application at full rates." |
