Abstract

THE EFFECT OF PREDACIOUS FUNGUS AND ORGANIC MATTER UPON THE SOIL POPULATION OF BEET EEL- WORM, HETERODERA SCHACHTII SCHM. 1) BY C. L. DUDDINGTON, (Regent Street Polytechnic, London) F. G. W. JONES (Rothamsted Experimental Station) AND F. MORIARTY (School of Agriculture, University of Cambridge) In 1955, a microplot experiment (JONES 1956) was undertaken to assess the effect of predacious fungi (DUDDINGTON 1955), with and without organic matter, upon the beet eelworm population of heavily infested soil. Details of the experiments are set out in Table I. The microplot soil, which was obtained originally from Chatteris, TABLE I Details of the
