Other claims from this paper (13)
- Intervention effect Seed meal amendment at 0.1% (vol/vol) significantly enhanced apple growth.
- Intervention effect Seed meal amendment at 0.1% (vol/vol) significantly suppressed apple root infection by Rhizoctonia spp.
- Intervention effect Seed meal amendment at 0.1% (vol/vol) significantly suppressed apple root infection by Pratylenchus penetrans.
- Intervention effect High glucosinolate B. napus seed meal did not consistently suppress apple root infection by Pythium spp.
- Intervention effect Low glucosinolate B. napus seed meal at 1.0% (vol/vol) significantly increased recovery of Pythium spp. from apple roots.
- Intervention effect Low glucosinolate B. napus seed meal at 1.0% (vol/vol) reduced apple seedling root biomass.
- Intervention effect When applied at lower rates, B. napus seed meal amendments enhanced populations of fluorescent Pseudomonas spp.
- Intervention effect Fluorescent Pseudomonas spp. were not recovered from soils amended with seed meal at 2% (vol/vol).
- Intervention effect Seed meal amendments increased soil populations of total bacteria and actinomycetes.
- Intervention effect B. napus cv. Dwarf Essex seed meal amendments were phytotoxic to apple at 2% (vol/vol).
- Intervention effect Phytotoxicity of the seed meal was not diminished when planting was delayed for 12 weeks after application.
- Mechanism For Rhizoctonia spp., disease control by seed meal operates through mechanisms other than glucosinolate hydrolysis products.
- Recommendation Seed meal amendments are a useful tool in the management of apple replant disease.
