BACKGROUND OF THE INVENTION In these trials, none of the experimental treatments reduced population densities of the plant parasitic nematodes, or Nematodes (derived from the Greek word for thread) are consistently promoted turf visual performance or turf root active, flexible, elongate, organisms that live on moist production (Crow (2005) Journal of Nematology, 37(4):477 Surfaces or in liquid environments, including films of water 482). Consequently there remains an urgent need to develop within soil and moist tissues within other organisms. While environmentally safe, efficacious methods of controlling only 20,000 species of nematode have been identified, it is plant parasitic nematodes estimated that 40,000 to 10 million actually exist. Many Some plant species are known to be highly resistant to species of nematodes have evolved to be very successful nematodes. The best documented of these include marigolds parasites of plants and animals and are responsible for 25 (Tagetes spp.), rattlebox (Crotalaria spectabilis), chrysan significant economic losses in agriculture and livestock and themums (Chrysanthemum spp.), castor bean (Ricinus com for morbidity and mortality in humans (Whitehead (1998) munis), margosa (Azardiracta indica), and many members Plant Nematode Control.

These developments are not Surprising the art. The present invention discloses other oxazoles, because few effective anthelmintic drugs are available and oxadiazoles and thiadiazoles with Surprisingly potent nem most have been used continuously. Some parasitic species aticidal activity showing activity comparable to commercial have developed resistance to most of the anthelmintics 25 standards.
