Pesticide use in crops is a severe problem some countries. Each country has its legislation for use, but they differ the degree of tolerance these broadly toxic products. Several synthetic pesticides can cause air, soil, and water pollution, contaminating human food chain other living beings. In addition, them accumulate environment an indeterminate amount time. The agriculture sector must guarantee healthy with sustainable production using environmentally friendly methods. this context, biological biopesticides from microbes plants are growing green solution segment. pests attack worldwide, including weeds, insects, nematodes, microorganisms such as fungi, bacteria, viruses, causing diseases economic losses. bioproducts microorganisms, microbial (MBPs) or alone, practice due to intense research world. Mainly, baculoviruses have been used sources biomolecules secondary metabolites biopesticide use. Different methods, direct soil application, spraying techniques endotherapy, seed treatment, used. Adjuvants like surfactants, protective agents, carriers improve system different formulations. tool bioremediation environment. This review summarizes topics, focusing on origin.

Nematophagous fungi (NF) are a group of diverse fungal genera that benefit plants. The aim this review is to increase comprehension about the importance nematophagous and their role in phosphorus solubilization favor its uptake agricultural ecosystems. They use different mechanisms, such as acidification medium, organic acids production, secretion enzymes metabolites promote bioavailability for This study summarizes processes solubilization, addition mechanisms action NF on crops, evidencing need include innovative alternatives implementation microbial resources management plans. In addition, it provides information help understand effect make available plants, showing how these biological means uptake, thus improving productivity yield.

Insects have an effective innate immune system to protect themselves against fungal invasion. Metarhizium employs a toxin-based strategy using nonribosomal peptide called destruxin A (DA) counteract the host response. However, mechanism by which DA inhibits insect immunity is still unclear. Here, we identified 48 DA-binding proteins in silkworm hemolymph, with binding affinity (K

Entomopathogenic fungi, often acknowledged primarily for their insecticidal properties, fulfill diverse roles within ecosystems. These encompass endophytism, antagonism against plant diseases, promotion of the growth plants, and inhabitation rhizosphere, occurring both naturally upon artificial inoculation, as substantiated by a growing body contemporary research. Numerous studies have highlighted beneficial aspects endophytic colonization. This review aims to systematically organize information concerning direct (nutrient acquisition production phytohormones) indirect (resistance induction, antibiotic secondary metabolite production, siderophore mitigation abiotic biotic stresses) implications Furthermore, thorough discussion these mechanisms is provided. Several challenges, including isolation complexities, classification novel strains, impact terrestrial location, vegetation type, anthropogenic reluctance use fungal entomopathogens, been recognized hurdles. However, recent advancements in biotechnology microbial research hold promising solutions many challenges. Ultimately, current constraints delineate potential future avenues leveraging entomopathogens dual control agents.
