Mycorrhiza-induced resistance in banana acts on nematode host location and penetration

► Mycorrhiza (AMF)-induced resistance against nematodes: modes of action unclear. ► AMF decrease burrowing nematode penetration in banana. ► Soil application of mycorrhizal root exudates also decreases nematode penetration. ► Nematodes showed reduced attraction towards mycorrhizal root exudates in vitro. ► Thus, AMF-induced resistance affects nematode penetration and exudates play a role.
