Abstract/Contents:Research is being done to determine the effects of eighteen herbicides or herbicide combinations on seaside aster, matchweed, and dallisgrass in a bermudagrass plot. The chemicals used in the test were: benazolin, dicamba, trimec, garlon, MSMA, triclopyr, EH-697, EH-707, EH-719-1, BBO, metribuzin, and some combinations of a few. In addition to determining the level of weed control of the herbicides, the phytotoxicity level of the bermudagrass was also watched very closely. The mixture of metribuzin and MSMA showed excellent control over the two broadleaf weeds, and had a moderate control on the dallisgrass. The phytotoxicity of this mixture in bermudagrass never exceeded a rating of 6.0, so it was a very effective control. Metribuzin alone showed no satisfactory control. None of the benazolin and dicamba (sodium fomulation) mixtures produced satisfactory results, nor did they prove phytotoxic to the bermudagrass. The potassium salt formulation of dicamba was also mixed with the benazolin and it showed a much better result in controlling the broad-leaf and dallisgrass weeds. Trimec applied alone showed good control of matchweed, with a fair control of aster and no damage to the bermudagrass. A mixture of trimec and Garlon, (#766 & #758) showed good control of matchweed and fair control of aster. Phytotoxicity to bermudagrass was high with the #766 conbination. All EH herbicides tested controlled both broadleaf weeds and dallisgrass, but they were also all highly phytotoxic to the bermudagrass.
