Effect of BAU-Biofungicide, Neem Oil and a Nematicide on the Root-Knot (Meloidogyne javanica) of Papaya (Carica papaya)

Abstract

In a pot experiment, BAU-Biofungicide (Trichoderma harzianum) neem oil and  curaterr (carbofuran) 5G were tested against root-knot (Meloidogyne javanica)  of two papaya varieties Kashempuri and Deshi papaya. Seedlings were  inoculated with second stage larvae of M. javanica. Neem oil (5 ml/ 10g seeds)  and BAU-Biofungicide (1:4) were used as seed treatant and curaterr as side  dressing. Both the bio-agents significantly increased the root and shoot growth  of papaya plant and reduction of galls and eggmasses and suppressed the  development of J₂, J₃, and J₄ and adult females of M. javanica. Efficacy of  BAU-Biofungicide was to reduce the gall and nematode development and to  increase plant growth was similar to nematicide curaterr. BAU-Biofungicide  gave higher effect in most of the growth characters compared to neem oil and  prevented the development of adult females and juveniles like nematicide  curaterr.
