Evaluation of the efficacy of Bacillus amyloliquefaciens against Ditylenchus angustus infection in rice

Abstract

The rice stem nematode Ditylenchus angustus causes “Ufra” disease in rice and causes substantial yield losses. Environmental side effects associated with chemical control of this nematode underline the urgent need for alternative environmental-friendly strategies. Antagonistic bacteria have been shown to be promising microorganisms for the biological control of plant-parasitic nematodes. However, there is little information about using bacteria to reduce the D. angustus infection in rice. We isolated and identified some bacterial strain as Bacillus amyloliquefaciens. It has been shown that man strains of plant-associated Bacillus amyloliquefaciens stimulate plant growth and produce secondary metabolites that suppress plant pathogens. The aim of this research is to evaluate the efficacy of our identified B. amyloliquefaciens against D. angustus infection in rice.
