Effect of Pratylenchus penetrans on the infection of Brown Stem Rot in adzuki bean

Abstract

Inoculation test was conducted to confirm the influence of Pratylenchus penetrans on the infection of adzuki bean by Phialophora gregata f. sp. adzukicola, causal agent of brown stem rot of adzuki bean, in the green house. It was considered that high densities of P. penetrans enhanced the invasion of P. gregata f. sp. adzukicola to adzuki bean and the ratio of the highest brownish node to total nodes of adzuki bean. From the result, P. penetrans was clarified as one factor which enhanced the invasion of P gregata f. sp. adzukicola to adzuki bean. Jpn. J. Nematol. 35 (2), 71-77 (2005).
