Abstract Beauveria bassiana and Metarhizium spp. are entomopathogenic fungi with potential applications beyond insect pest control, including plant disease suppression, plant growth promotion, and rhizosphere colonization. This study investigated the plant growth-promoting characteristics and extracellular enzyme activities of Metarhizium spp. and B. bassiana in relation to phytopathogen interactions and plant growth. Additionally, the efficacy of these fungi in mitigating damping-off and root rot caused by Rhizoctonia solani on cucumber plants was evaluated in vitro and in vivo. Results indicate that B. bassiana and M. anisopliae produce indole-3-acetic acid, hydrocyanic acid, and hydrolytic enzymes. Seed treatment with these fungi significantly reduced disease severity (3.85%–1.86%, respectively)… More >

Abstract The objective to this work was to evaluate the enzymatic activity in the culture of Solanum lycopersicum L. infected with Fusarium oxysporum after the combined application of Beauveria bassiana and plant extracts. Solanum lycopersicum plantlets were transplanted 15 days after the emergency. Five days after transplanting, Beauveria bassiana spores were applied at a concentration of 1 × 10⁷ spores mL⁻¹ onto soil (along with A. indica (N) and P. auritum (H) leaf extracts) where S. lycopersicum plants were planted. Eight days after transplanting, spores of F. oxysporum strain were applied at a concentration of 1 × 10⁶ spores mL⁻¹ to soil where S. lycopersicum plants were growing.… More >

Abstract The objective of this work was to evaluate the effect of Beauveria bassiana (Bb 1205) on controlling Fusarium oxysporum f. sp. lycopersici (Fol 17108) in tomato plants in greenhouse conditions. Inoculation of Bb 1205 was the most promising among the agronomic variables and expression of the activity of the enzymes β-1,3-glucanases and chitinases. Inoculation of Bb 1205 occurred at a concentration of 1 × 10⁸ conidia·mL⁻¹, which was administered onto the leaves, directly into the soil and via injection. Infection with Fol 17108 occurred with 1 × 10⁶ spores·mL⁻¹, which were added directly to the soil. Spectrophotometry was used for measuring agronomic… More >
