PETAL BLIGHT: Botrytis cinerea It is confined to older flowers during cold damp weather; it is most common on various genera; small, circular spots often bordered by a delicate rim of pink; the imperfect stage Botrytis cinerea is the most destructive; destroys flowers; spray with Benlate 50WP at 1 ttpg. 30 days apart; also spray flowers just prior to opening. BU43 0
PETAL BLIGHT: Caused by Fungi Other Than Botrytis 16 other fungi have been found as causes; many are saprophytes living on decaying leaves, flowers, potting mixes; all such must be removed from under benches and bench tops; periodical spraying of floors, walls, ceiling and plant foliage with fungicide such as Captan, Actidione, Nabam, Zineb, Maneb, Ferbam, etc. is necessary; use Nystatin or Natriphene on cut flowers.
