Five foliar applications of 1.12 kg a.i./ha of oxamyl or carbofuran at 10-day intervals beginning when 90% of the plants had emerged suppressed increase in G. rostochiensis densities. Biological control of nematodes is an increasingly popular strategy because it is effective and has low environmental impact. Sci., 17: 623-627 An experiment was conducted under glass-house conditions to test the effects of five plants products in the form of drenches on the growth of potato and population density of potato cyst nematode Globodera rostochiensis.

On susceptible potato cv. Only one full generation was completed per year under these latitudes. Consignments of potato tubers, rooted plants and bulbs from countries where the nematodes occur may be examined to check amounts of adhering soil, if any, or to take samples of soil for laboratory examination. The experiments of Ellenby and Gilbert (1958) are the only evidence that Ca2+ may contribute to the hatch-stimulating action of potato-root exudate. Abstract.
