| Abstract/Contents: | "The experiment was conducted in a golf course fairway near Florence, SC on 9 Jul 99. Plot dimension was 21-ft x 100-ft, with 4 replications in RCB design. At application, air temperature was 80 F and soil temperature at 4-in depth was 79 F. Soil moisture was near field capacity. Soil type was loamy sand, pH 6.1. The area had a history of nematode infestation, particularly with Belonolaimus sp. (sting nematode). Plots were maintained by the golf course staff and were mowed at 0.5 in weekly. Curfew (1,3-dichloropropene) was injected behind vertical coulter plates mounted on a tractor implement. Coulters were on 12-in centers and coulter depth adjusted to slice turf and inject fumigant approximately 5-in deep. Nemacur (fenamiphos) was applied using a drop spreader. Immediately after treatments were applied the experimental area was irrigated with approximately 0.25-in water. Turf quality measurements and soil samples for nematode analyses were taken on 26 Jul, 13 Aug, and 10 Sep. Turf quality was assessed (1 to 9 scale, with 9 being best) by dividng plots into 4 equal quadrats and the quality averaged in each plot before statistical analysis. Samples were taken for nematode analysis with a standard 1-in soil probe. Soil cores were taken about 4-5 in deep, with 30 soil cores collected from the center of each plot in a zigzag pattern. Samples were bulked in a plastic bucket, mixed and stored in labeled plastic bags. Samples were kept in an ice chest to moderate temperatures and assayed immediately by elutriation and sugar flotation. Values of nematode counts are in numbers/100 ml of soil. Plots were examined 4 days after application for evidence of fumigant injury. There was a slight amount of injury (yellowing) of foliage adjacent to the coulter slice that extended approximately 1-in [on] either side of the sliced turf. About 2 weeks after application, phytotoxicity was no longer evident. Curfew at either 3 or 5 gal/A gave the best turf quality. Turf quality was much better in the Curfew treated plots than in any of the other plots, and turf quality persisted throughout the study even though nematode counts did not reflect turf quality improvement. Nematode counts were erratic and counts did not refelect differences noted in turf qulaity. The phytotoxicity encountered with Curfew was expected, but was of a transient nature and was acceptable considering the improvement in turf quality that resulted." |
