Title

The enemy of my enemy is my friend: Trichoderma fungi reduce root rot disease symptoms caused by Phytophthora cinnamomi in Rhododendron

Abisola Eniola Folorunso; Jean H. Burns Plant Ecology 2026. doi:10.1007/s11258-026-01627-0

Other claims from this paper (10)

Intervention effect Phytophthora cinnamomi inoculation reduced Rhododendron survival and growth.
Intervention effect Trichoderma increased Rhododendron biomass in the presence of the pathogen.
Intervention effect Trichoderma reduced Rhododendron leaf damage in the presence of the pathogen.
Observation R. molle showed the strongest growth benefit from Trichoderma.
Observation R. schlippenbachii was less responsive to Trichoderma.
Intervention effect Dual Trichoderma inoculation added no benefit for leaf damage, biomass, or growth.
Intervention effect Dual Trichoderma inoculation produced additive responses in survival and root allocation traits.
Observation The authors infer that combining Trichoderma strains can reduce protection.
Mechanism The authors suggest competition among Trichoderma as an explanation for less-than-additive responses.
Recommendation The authors suggest that Trichoderma co-inoculation may be counter-indicated.
