| Abstract/Contents: | "Four tests on Kentucky bluegrass (Poa pratensis L.) under sod production were initiated to evaluate herbicides for the selective post-emergent control of yellow nutsedge (Cyperus esculentus L.). The effects of early and late summer treatment and repeat applications was also investigated. Control was based on visual estimates of nutsedge foliar cover before and after treatment. Promising results were obtained from certain treatments of BAS-3510, BAS-3516 (liquid form of 3510), DSMA, MBR-8251, and S-21634 while results with 2,4-D were disappointing. Some turf injury was noted from 2,4-D, MBR-8251, and S-21634. The evaluation of 2,4-D and DSMA applied in the late summer of 1971 (Table 1) and of MBR-8251 in late summer 1972 (Table 2) is not conclusive. There was insufficient time for the materials to work prior to all nutsedge foliage naturally turning brown by early October. 2,4-D however did injure bluegrass while BAS-3510 was effective and quick acting, Nutsedge turned brown within several days while browning from other materials took 2 to 3 weeks. The slowest acting material was MBR-8251. There also was evidence that control of nutsedge in young turfgrass resulted in increased turfgrass cover. Late summer treatments of BAS-3510 and DSMA were more effective than those made in early summer. Lower rates and less frequent applications were required. This could be associated with the fact that nutsedge was about to die back for the year. Overall the best treatments were those applied at low rates and more frequently. The most promising treatments were BAS-3510 at 1 lb ai per acre - 2 applications (10 days apart) in late summer or 3 applications in early summer, and DSMA at 4 lb per acre with similar application requirements. Results with MBR-8251 and S-21634 at 4 lb per acre appear satisfactory although some turf injury was detected. Further work is required with these materials, as well as with BAS-3510 and DSMA, before satisfactory recommendations can be made." Trials were carried out on Kentucky bluegrass (Poa pratensis) under sod production. BAS-3510 [bentazon] at 1 lb/acre, applied twice with a 10-day interval in late summer or 3 times in early summer, and similar applications of DSMA at 4 lb/acre gave the best control of yellow nutsedge (Cyperus esculentus). MBR-8251 [4'-(phenylsulphonyl)-1,1,1- trifluoromethylsulphono-o-toluidide] and S-21 634 [1-methyl-4-phenylpyridinium chloride] at 4 lb/acre, applied in August, gave promising results although some turf injury was observed. |
