Biological control of plant parasitic nematodes on black pepper with endophytic bacteria and organic materials

Abstract

Plant parasitic nematodes have been reported to cause signigicant demage and losses to black pepper in Bangka, Indonesia Control of plant parasitic nematodes with pesticides is often restricted due to their high toxicity and negative impact on the environment. Endophytic microorganisms resident within plant tissues have attracted attention due to their interesting features related to plant growth and for the bioprotection of plants against plant pests and diseases. In this study, endophytic bacteria were collected and isolated from different varietes of healthy pepper. The isolation of endophyte was conducted using surface strelized method. The objective of this research was to evaluate the effect of endophytic bacteria and organic materials on yellow diseases caused by plant parasitic nematodes Meloidogyne sp. on black pepper. The results showedw that application of endophytic bacteria and organic materials were able to suppress the number root galls caused by Meloidogyne sp and the juveniles of nematodes in the soil and also to increase the plant growth of pepper seedings in the greenhouse.
