Combined effects of root-associated entomopathogenic and mycorrhizal fungi on the foliar pathogen Botrytis cinerea in tomato

•Entomopathogenic fungi (EPF) reduced foliar disease symptoms in tomato plants.•Arbuscular mycorrhizal fungi (AMF) only affected plant growth, not disease.•Fungal combinations showed functional complementarity for plant protection and growth.•Effects in combinations were independent of root colonization pattern.•Root inoculation by EPF decreased in presence of AMF, while AMF was unaffected by EPF.
