摘      要：Beauveria bassiana and Metarhizium *** entomopathogenic fungi with potential applications beyond insect pest control,including plant disease suppression,plant growth promotion,and rhizosphere *** study investigated the plant growth-promoting characteristics and extracellular enzyme activities of Metarhizium *** *** in relation to phytopathogen interactions and plant ***,the efficacy of these fungi in mitigating damping-off and root rot caused by Rhizoctonia solani on cucumber plants was evalu-ated in vitro and in *** indicate that *** and *** produce indole-3-acetic acid,hydro-cyanic acid,and hydrolytic *** treatment with these fungi significantly reduced disease severity(3.85%–1.86%,respectively)and enhanced germination parameters[germination percentage(85.33%–86%,respectively),germination index(10.67–12.29,respectively),seedling length vigor index(86.41–109.44,respec-tively),and seedling weight vigor index(30.24–37.57,respectively)]compared to the control *** fungi demonstrated high inhibition rates of *** mycelial growth(93.90%–90.46%,respectively).Greenhouse trials revealed that preventive treatments using *** and *** increased catalase(104.40–105.52 units/mg protein/min,respectively),(4.58–5.77 units/mg protein/min,respectively),superoxide dismutase(40.65–41.74 units/mg protein/min,respectively),and polyphenol oxidase(0.539–0.559 units/mg protein/min,respectively)activities,as well as total phenolic(2.60–2.65 mg/g,respectively)and total sugar content(2.23–2.16 mg/g,respectively)in cucumber ***,disease severity(9.51–6.99%,respectively)was reduced,and plant height(93.76–98.76 cm,respectively)increased compared to the positive ***find-ings suggest that *** and *** can enhance plant growth,stimulate plant defense mechanisms,and effectively control damping-off and root rot diseases,making them promising candidates for b
