Microbial Biopesticides against Bacterial, Fungal and Oomycete Pathogens of Tomato, Cabbage and Chickpea

Biological control is an environmentally friendly approach that holds promise to complement or replace chemicals effectively protect crop plants against pests and pathogens. Environmental samples with highly diverse competitive microbiomes harbor antagonistic microbes modes-of-action can provide a rich source of microbial biopesticides. In the current study, bacteria isolated from rhizosphere soil food spoilage were subsequently screened various plant fungal oomycete pathogens in growth inhibition assays. These included new potential biocontrol Corynebacterium flavescens, Sporosarcina aquimarina saromensis anti-fungal antioomycete activities. Potential candidates selected by preliminary screening assays then applied tomato, cabbage chickpea bacterial (Pseudomonas syringae pv. tomato), (Alternaria brassicicola) (Phytophtora medicaginis) phytopathogens. Ten biopesticides demonstrated be effective these diseases, led significant (p < 0.05) reductions symptoms and/or pathogen DNA compared mock-treated diseased plants. We conclude rapidly biodiverse microbiomes, where may employ features compete each other.
