Calcium reduces Botrytis cinerea damage to plants of Ruscus hypoglossum.

Plants of R. hypoglossum were grown in pots containing perlite or soil under simulated commercial conditions for 3 winter seasons. A significantly lower severity (up to 78%) of B. cinerea rot was observed on branches treated with NPK fertilizer supplemented with calcium. Application of Ca(NO3)2 to bushes infected by B. cinerea significantly reduced disease severity when plants were grown in soil, while disease reduction on plants grown in perlite was not significant. Application of Ca(NO3)2, CaCl2 or CaSO4 to mature cut branches standing in water, significantly reduced postharvest rot. Application of gypsum or superphosphate to Ruscus plants effectively reduced the susceptibility of cut branches to infection by B. cinerea.
