Other claims from this paper (9)
- Intervention effect Em7 inhibited Sclerotinia sclerotia germination.
- Observation Sclerotinia hyphae leaked and their cytoplasm disintegrated in the presence of Em7.
- Observation Em7 inhibited mycelial growth of numerous plant pathogenic fungi.
- Observation Em7 caused branching, swelling and cytoplasmic collapse in fungal structures.
- Intervention effect Greenhouse Em7 spray reduced leaf and stem rot incidence and severity.
- Intervention effect Applying Em7 one day before pathogen inoculation gave higher control efficacy than applying it afterward.
- Intervention effect Two Em7 applications at blossom significantly reduced field disease incidence and severity by 50–70%.
- Observation Em7 and the carbendazim or tebuconazole fungicides did not differ significantly in control efficacy.
- Recommendation The authors propose Em7 as a biological control agent for oilseed rape Sclerotinia stem rot.
