Abstract

Three nematicides were evaluated for control of Belonolaimus longicaudatus, Hoplolaimus galeatus, Criconemella spp., and Meloidogyne spp. in 'Tifgreen II' bermudagrass mowed at golf course fairway height (1.3 cm) in Fort Lauderdale, Florida. Bermudagrass plots were treated with fenamiphos (13.5 kg a.i./ha), oxamyl (13.5 kg a.i./ha), or 30% formaldehyde (6.4 liter a.i./ha). The plots treated with fenamiphos or formaldehyde were split 14 days later and one-half of each plot received two biweekly applications of formaldehyde. Forty-two days after the treatments were applied, the turfgrass vigor ratings and dry root weights in plots treated with fenamiphos were higher (P 0.05) than the control, oxamyl, or formaldehyde treatments. The population levels of B. longicaudatus were suppressed (P 0.05) in the fenamiphos, fenamiphos plus formaldehyde, and oxamyl treatments. Key words: Belonolaimus longicaudatus, bermudagrass, chemical control, Criconemella spp., fenamiphos, formaldehyde, lance nematode, Hoplolaimus galeatus, Meloidogyne spp., oxamyl, ring nematode, root-knot nematode, sting nematode, turfgrass.
