Excellent topic: Chemical Control Agents Used Against the Gypsy
| Community Health Assessment of a Community | Methods and compositions for the control of nematodes are disclosed. Specifically, fatty acid ester compounds have been found to advantageously control nematodes at concentrations which are non-phytotoxic. The fatty acid ester compounds can be used in conjunction with other nematicidal agents such as free fatty acids, fatty acid salts, avermectins, ivermectin, and www.informationsecuritysummit.org by: The US used some 1 kg ( pounds) per hectare of arable land compared with: kg in China, kg in the UK, kg in Cameroon, kg in Japan and kg in Italy. Insecticide use in the US has declined by more than half since .6%/yr), mostly due to the near phase-out of organophosphates. |

Cross-Reference to a Related Application This application is a continuation-in-part of co-pending application Serial No. Nematodes are important plant pests which cause millions of dollars of damage each year to turf grasses, ornamental plants, and food crops. Efforts to eliminate or minimize damage caused by nematodes in agricultural settings have typically involved the Contol of soil fumigation with materials such as chloropicrin, methyl bromide, and dazomet, which volatilize to spread the active ingredient throughout the soil. Such fumigation materials can be highly toxic and may create an environmental hazard.

Various non-fumigant chemicals have also been used, but these too create serious environmental problems and can be highly toxic to humans. The accepted methodology for control of nematodes afflicting animals has centered around the use ofthe drug rjenzimidazole and its congeners.
The use of these drugs on a wide scale has led to many instances of resistance among nematode populations Prichard, R. Saunders, New York. See, for example.
Bizzell [] Jour, of Parasitology [abstract]. Several patents have issued describing the control of nematodes with B. See, for example, U. Patent Nos. The pesticidal activity of avermectins is well known. The avermectins are disaccharide derivatives of pentacyclic, membered lactones. They can be divided into four major compounds: A.]
