Abstract/Contents:"Kikuyugrass has been found to be one of the most serious problems for turf production in the coastal area of southern and central California. Currently, no chemical control method has proved adequate. However, repeated applications of herbicides which limit the growth of kikuyugrass relative to the desirable turf species may prove helpful. For this reason, the following trial was established. Six turfgrass cultivars (perennial rye, tall fescue, bluegrass, common Bermuda, hybrid Bermuda, and zoysia) were plugged into a 9 month old stand of established kikuyugrass. Four 4-inch plugs were placed in 5 by 5 ft sections of the sward. After a 6 week establishment period, the plots received their first herbicide treatment. The herbicide treatments consisted of MSMA, triclopyr, and MSMA plus triclopyr. The application rate of MSMA and triclopyr was 2 and 0.5 lb/A. Treatments were made on August 23, September 13, and October 12, 1990. Treatments were applied at a spray volume of 30 gal/A with a constant pressure CO2 backpack sprayer. Treatments were replicated four times. Three evaluations were made, 3 weeks after each of the three herbicide treatments. Evaluation was made by measuring the diameter of the plugs to distinguish the competitive relationship between the kikuyugrass and the six turf species. Where kikuyugrass was most competitive, plug diameters decreased and where the turf variety was more competitive, plug diameter remained constant or increased depending on whether the turf cultivar was a bunch type or formed rhizomes. Factorial analysis showed significant differences for herbicide treatment, turf cultivars and the interaction of turf cultivars and herbicide treatments. All of the herbicide treatments reduced the competitiveness of the kikuyugrass relative to the turf species. Common Bermuda was injured by triclopyr treatment, however, none of the other turf species was injured by herbicide treatment. This trial indicated that sequential herbicide treatment could be used to alter the competitive relationship between kikuyugrass and turf species and could be effective for kikuyugrass control."
