| Abstract/Contents: | "The ectoparasitic sting nematode, Belonolaimus longicaudatus Rau, is a major pest to warm season turfgrasses cultivated in sandy soils in Florida. The most commonly used postplant nematicide for sting nematode management is fenamiphos. Although fenamiphos has been shown to be effective in the field for suppressing populations of the sting nematode, dose-mortality data is not available. Survival of adults of the sting nematode was assessed after exposure for 14 days in vitro in several concentrations of fenamiphos or fenamiphos sulfone. Starting and final concentrations of fenamiphos and its metabolite, fenamiphos sulfone, were measured with gas chromatography (GC). At the conclusion of the exposure, nematodes were washed free of pesticide and inoculated into square pot cultures of the highly susceptible FX-313 St. Augustinegrass (Stenotaphrum secundatum [Walt.] Kuntze) for quantification of population establishment. 429 ppm was required to reach an estimated LC50 for fenamiphos sulfone compared with about 166 ppm for fenamiphos. Comparisons of sustained 14-day levels of fenamiphos and fenamiphos sulfone at three different depths in the soil of a USGA-type green with our sting nematode survival data suggest that short term survival is not altered by the contact mode of action of fenamiphos or fenamiphos sulfone when the pesticide is applied at the currently labelled rate (11.25 kg a.i./ha). Population suppression of sting nematode, when observed in the field, is probably due to temporary nematostasis or irreversible sublethal effects caused by contact action and/or the systemic action of the nematicide." |
