| Abstract/Contents: | "Field studies were conducted in New Jersey, Pennsylvania, and Ohio to evaluate the efficacy of fall applications of granular and wettable powder oxadiazon formulations for smooth crabgrass (Digitaria ischaemum Schreb.) control the following spring. Turfgrass species in the trials included tall fescue (Festuca arundinacea Schreb.), red fescue (Festuca rubra L.), Kentucky bluegrass (Poa pratensis L.), and creeping bentgrass (Agrostis palustris Huds.). Fall applications of granular oxadiazon at 3.36 and 4.48 kg ai/ha provided excellent control of smooth crabgrass at 10 months post-treatment that was comparable to spring applications of 3.36 kg ai/ha of oxadiazon granular or pendimethalin. Fall application of oxadiazon granular at 2.24 kg ai/ha or oxadiazon wettable powder at 2.24 - 4.48 kg ai/ha failed to provide acceptable (80% or better) smooth crabgrass control at 10 months after treatment. Split applications of granular or wettable powder oxadiazon in the spring prior to crabgrass germination also provided excellent control. Lower rates were erratic in performance. No phytotoxicity was observed from oxadiazon granular applications to tall fescue, red fescue, or Kentucky bluegrass. Fall application of oxadiazon granular to creeping bentgrass caused objectionable discoloration that was temporary and was not evident at spring greenup. Fall applications of greater than 1.68 kg ai/ha of oxadiazon wettable powder resulted in unacceptable injury to red fescue and creeping bentgrass that was still evident the following spring. No objectionable phytotoxicity was observed on tall fescue or Kentucky bluegrass." |
