Biological control agents (BCAs) from different microbial taxa are increasingly used to control bacterial wilt caused by Ralstonia solanacearum. However, a quantitative research synthesis has not been conducted on the role of BCAs in disease suppression. Therefore, the present study aimed to meta-analyze the impacts of BCAs on both Ralstonia wilt disease suppression and plant (host) growth prom...

trichoderma is one of the important biocontrol agents for certain plant disease that control with different mechanisms. this fungus similar to other biocontrol agents is under the influence environmently factors. medium is one of these factors. this study was investigated effect of the medium (mol.c.b.m.) containing sugar beet molasses, corn steep liquor, baker’s yeast and malt extract as the l...

the experiment was done in a factorial design based on completely randomized with three factors and five replications in vitro. the first factors, plant extract (nine plant species), the second factor, solvent (5 solvent) and the third factor, concentration (3 concentration) were considered. in pot condition, the experiment was carried out in factorial based on completely randomized design with...

Biological control agents are useful components in the enhancement of plant disease resistance and improvement of soil properties. Effect of biological control agents (BCAs) as a disease control method in plants is hampered by their vulnerability to environmental and edaphic conditions. This study entailed the use of chitosan-silica nanocomposites for delivery of BCAs. Effect of BCAs-nanocompos...
