Postharvest control of Botrytis cinerea on cut rose flowers with pyrrolnitrin.

Pyrrolnitrin (an antibiotic isolated from Pseudomonas cepacia) was tested for postharvest control of B. cinerea infections on cut Sonia and Royalty rose flowers. After pyrrolnitrin was applied as a bud dip, buds were inoculated with conidia of B. cinerea and stored for 7 d at 2 deg C. No phytotoxicity was observed on leaves or petals at concn of pyrrolnitrin up to 200 mg/litre. Dip treatment with 100 mg/litre reduced lesion development by c. 90% compared with inoculated control flowers and prevented poststorage flower rot. This degree of disease control was comparable to that achieved with 1800 mg vinclozolin/litre (the max. label rate).
