Microbial consortium of biological control agents for plant protection and growth promotion

Abstract

Beneficial microorganisms play a crucial role in modern agriculture, serving as biopesticides, biostimulants/biofertilizers, and abiotic stress mitigators in crops. Their multifaceted functions significantly contribute to crop health and sustainability, aligning with the principles of regenerative agriculture by minimizing carbon footprints and reducing reliance on chemical agricultural inputs. The concept of 'microbial consortia,' involving the combination of multiple species or strains of fungi and bacteria, has gained recognition for its potential benefits compared to single-species/strain applications. This method aims to employ a spectrum of ecological functions, encouraging biological balance within agricultural systems. Recent research highlights how microbial consortia can directly and indirectly improve plant health through various mechanisms and interactions with their host plants. This review presents examples demonstrating the efficacy of microbial consortia as biopesticides and biostimulants/biofertilizers. These consortia show potential in managing plant diseases and pests while promoting plant growth and mitigating specific abiotic stresses in crops. Additionally, this thesis explores, in Chapter One, a review of the recent use and future prospects of microbial consortia in agriculture, presenting examples from the dynamic Brazilian market of biological products. In Chapter Two, the dual potential of fungi is explored, both for pest control and for plant disease control, which can be utilized in integrated pest management. This thesis aims not only to highlight emerging possibilities in this field but also to provide examples of promising strategies for managing bean wilt and whitefly infestations.
