| Abstract/Contents: | "This research evaluated the phytotoxicity of 13 herbicides on Bermudagrass (Cynodon dactylon (L.) Pers.) and the best chemical control for Kikuyugrass (Pennisetum clandestinum Hochst ex Chiov.) for the vegetative stage. The research was carried out in the pre-Andean range piedmont in Santiago de Chile, situated at 33.5° South and 70.5° West, during winter and summer of 1996. Seven preemergence (Dymethyl tetrachloroterephalate - DCPA, ethofumesate, napropamide, oryzalin, pendimethalin, propizamide and simazine) and six postemergence (fenoxaprop, glyphosate, imazapyr, nicosulfuron, sethoxydim and sulfometuron) herbicides were tried. Rates used were those recommended by the manufacturers. Preemergence herbicides were sprayed using 200 1 ha-1 of water and followed by 12 mm of irrigation for all the treatments. Initial and final populations were determined for both species. Visual turf quality was evaluated 7, 14, 21, 30 and 45 days after the application, for phytotoxic effects of the herbicides on Bermuda and Kikuyugrass. At the end of the assay (day 45), samples of rhizomes and stolons were taken, consisting of three nodes each (10 cm long), of both species and samples were put in germination trays for 7 days at 25 ± 2°C. Percentage of germinated rhizomes and stolons, and percentage of sprouted buds was recorded. Although some of the preemergence herbicides affected stolon or rhizome sprouting, none reduced Kikuyugrass population. These herbicides were applied during winter season on established lawn. In the assay with postemergence herbicides, all of them had some effect on the reduction of Bermudagrass, Kikuyugrass or both. Best results in terms of Kikuyugrass control were obtained with glyphosate at a rate of 1.92 kg a.i. ha-1. However, Bermudagrass, which was actively growing, was seriously damaged by this herbicide. Nicosulfuron was the preemergence herbicide with the least effect on Bermudagrass lawn. Chemical control of Kikuyugrass should consider the presence of seeds in the ground that are a permanent reinfestation source." |
