TABLES OF NEMATODE-PATHOGENICITY

N. Sasanelli

Abstract


"Tables of nematode-pathogenicity" were calculated on the basis of the relation between nematode density and damage to plants as characterized by the Seinhorst's equation y = m + (1 - m) Z[supPĂ»[supT]). This equation was transformed by a logarithmic manipulation, as y = m + (1 - m) 1.05^ [(P/-7) + 1] and solved considering values of T and m from the literature. These Tables allow an easy and quick evaluation of yield losses far each known crop-nematode relation.
