摘要：
The entomopathogenic fungus Metarhizium anisopliae (Metchn.) Sorokin can grow endophytically in crops such as tomato, often inhibiting the growth of pests and diseases. Different isolates of M. anisopliae vary in their protective properties and require careful assessment prior to their use in any application. We evaluated isolates WEU01 and WEU02 of M. anisopliae for their ability to colonize tomato plants, promote plant growth, suppress spider mites, and inhibit black spot infections caused by Alternaria alternata. Both fungal isolates grew systemically within tomato plants, persisted in plant vegetative tissues for up to eight weeks, reduced spider mite populations, and were antagonistic to A. alternata in vitro and in planta. After four weeks, endophytic M. anisopliae positively affected leaf area, leaf number, stem length, stem diameter, dry weight, and chlorophyl content. These results illustrate the potential benefits of endophytic M. anisopliae for biological control of pests and diseases on tomato.
