EFFECT OF CADUSAFOS AND CARBOFURAN AGAINST PRATYLENCHUS PENETRANS AND SOME ECTOPARASITIC NEMATODES INFESTING POTATO IN CYPRUS

Abstract

Cadusafos (as Rugby[sup(][supR][sup)]) and carbofuran (as Furadan[sup(][supR][sup)]) at the rates of 4 and 6 kg a.i. per hectare, respectively, applied prior to planting of potatoes cv. Spunta, controlled the lesion nematode Pratylenchus penetrans in roots and soil increasing yields significantly by 26 and 13 per cent, respectively, over the untreated. At harvest, the numbers of P. penetrans within roots were negatively correlated with yield of potato. The nematicides produced only modest decreases in numbers of ectoparasitic nematodes which were not correlated with increases in yield.
