Abstract/Contents: | "Various nematicides were applied annually (spring or fall) or semiannually (spring and fall) to established centipedegrass on Edisto loamy-sand at the U.S. Department of Agriculture Plant Introduction Station (Savannah, Georgia) to determine if nematode control would affect centipedegrass. Liquid nematicides were applied with a hose-end proportioner. Granular materials were distributed evenly over the plots. All plots were watered immediately after application. Soil samples were removed every 3 months, and the populations of major nematodes determined by sieving-centrifugation. Ring nematodes (Criconemoides ornatus) were the most numerous averaging 112 per 100 cm3 soil over the 3-year period. This population density was below that which would be expected to The JOURNAL OF NEMATOLOGY for Annual Abstracts, Society of Nematologists 331 produce observable symptoms. Maximum population was 902. Neither Chemagro 7375 (2.22 kg 15G/100 m2) nor oxamyl (Vydate- 1.39 kg 10G/100 m2) reduced ring nematode populations when applied semiannually for 3 years, but both reduced populations of other nematode species. Carbofuran (Furadan-1.45 kg 10G/100 m2) or DBCP (Nemagon-9.71 kg 10G/100 m2) applied semiannually for 2 years reduced ring, lesion, spiral, and dagger nematode populations. Carbofuran reduced overall populations by 80%; DBCP by 58%. Average ratings of grass coverage and appearance in treated plots were not different from nontreated plots during this 3-year period, indicating that populations present may not affect centipedegrass." |
