Pathogenicity of Meloidogyne incognita infecting Mungbean

Abstract

Pathogenicity trial of Meloidogyne incognita was conducted consecutively for two different seasons on mungbean (C.V.Dhauli) under net house conditions. With increase in the initial inoculums density of M. incognita, there was progressive decrease in various growth parameters and increase in nematode population in soil as well as in plant roots during both the seasons under investigation. The maximum reduction in plant growth parameters was observed at an inoculums level of 10,000 J2/kg soil. Pooled analysis of data also indicated a similar trend. Thus the estimated damaging threshold level of M. incognita in mungbean (CV.Dhauli) was 100J2 /kg soil.
