Beziehungen zwischen der Anwendungsmethode und der Wirkung des Nematizids Nemacur gegen Meloidogyne javanica (Treub) in Tomatenwurzeln

Abstract

Granular organophosphate nematicide, Nemacur 5% G was tested againstMeloidogyne javanica in tomato roots in sandy clay-loam soil at the rate of 1,5 kg a.i./feddan under three different methods of application. Results indicated that applying half of the nematicide dose two weeks pre-transplanting and the rest at transplanting time was the best method tested based on percent suppression in nematode population. Not much worse results gave the applying of all the nematicide dose simultaneously at transplanting. The effect was essential smaller when the half of the nematicide was given at transplanting time and the rest dose followed two weeks later.
