e1“population density of AM spores in the soils seems to be low in the clean cultivated orchards, subjected to frequent fungicide sprays, whereas it was high under sod culture.”

Other claims from this paper (8)
- Observation Intensively managed orchards generally had high major-element levels in soil attributed to periodic fertilization.
- Observation Leaf major-element content in intensively managed orchards was within the recommended range.
- Observation Apple orchards without fertilizer or fungicide maintained high AM infection throughout the season.
- Intervention effect AM infection in kiwifruit roots decreased in July and August after three June fungicide sprays.
- Intervention effect AM infection in Iyo tangor decreased in July after four fungicide applications in May and June.
- Intervention effect Peach under sod culture retained relatively high AM infection after five fungicide sprays.
- Observation AM spore density seemed low in clean-cultivated orchards frequently sprayed with fungicide.
- Mechanism The authors conclude that excessive fertilization, frequent fungicide spraying and clean culture adversely affect AM spores and tree infection in orchards.
