| Abstract/Contents: | "This trial was conducted on a private golf course fairway in Rancho Mirage, CA. High numbers of sting nematodes were associated with declining and dying bermudagrass during the summer months and poor establishment of the overseeded ryegrass in the fall. The turf was maintained under conventional management conditions. A newly designed pesticide application system was used which delivered the treatments uniformly as a soil drench during a 70 minute application period. The system was based on interconnected low volume drip irrigation lines with emitters spaced on 30 cm centers. The 23mā plots were arranged in a randomized complete block design with 3 replications per treatment. The water front moved through the sandy soil to a depth of approximately 30 cm. One treatment was immediately covered with a 1mm plastic tarp to reduce rapid losses of the fumigant. The treatments were applied after sunset to avoid excessive losses of the fumigant due to high day time temperatures. Air and soil temperature at time of application were about 27C and 25C, respectively. The tarp was removed after 48 hr. One month later the turf was de-thatched and overseeded with ryegrass. Twelve days after treatment 10 soil cores were removed from each plot, pooled and thoroughly mixed in a plastic bag. This sampling was repeated in monthly intervals. Two 50cc subsamples were taken from each bag and processed by a combination of wet sieving and sugar centrifugation. The extraction efficacy was approximately 33%. Both fumigant treatments initially reduced the sting nematode population close to the detection level. The nematode suppression lasted for almost a year. Fall seeded ryegrass established faster and thicker in the treated plots. Three weeks after emergence both root and shoot growth were considerably larger in the fumigated plots than in the control. In addition to the growth of plants, the treated plots were luscious green in appearance compared with pale green color in the controls. This difference remained visible for several months. Similar differences continued into the spring when the declining cool-season ryegrass was succeeded by the summer cover of bermudagrass." |
