Abstract

Of 1915 flowering plants 23 % gave extracts which completely inhibited the germination of the conidia of Venturia inaequalis under the experimental conditions used. The plants which gave active extracts are distributed throughout the Angiosperms, and there is no correlation with systematic position. The inhibitors were distributed generally in some plants and were localized in others, e.g. to the leaves.Some extracts appeared merely to inhibit the germination of the conidia while others killed them.Some inhibitors disappeared when the plants were dried, other dry material was still active when retested several months later. Hedera Helix contains an inhibitor which is active when the extract is diluted 128 times.
