Title

V. Carré‐Missio; F.A. Rodrigues; D.A. Schurt; et al. Annals of Applied Biology 2014. doi:10.1111/aab.12109
Other claims from this paper (6)
- Intervention effect Foliar silicon concentration did not differ significantly between water and potassium silicate sprays.
- Intervention effect Potassium silicate increased Si deposition on coffee leaves versus water.
- Intervention effect Rust severity reached 32% with potassium silicate versus 44% with water at 36 days after inoculation.
- Intervention effect Water sprayed leaves had more uredia than potassium silicate sprayed leaves at 36 days.
- Intervention effect Potassium silicate treated leaves had less fungal colonisation than water sprayed leaves.
- Mechanism The authors suggest a physical role for polymerised potassium silicate, an osmotic effect on urediniospore germination, or both.
