Abstract

English

In the present study the plant activator BTH (= benzothiadiazole) (BION ® ) and an extract from leaves of Hedera helix were assayed on resistance inducing effects against fire blight caused by Erwinia amylovora, strain Ea7/74 on the highly susceptible apple rootstock M26. The experiments were carried out under controlled climatic conditions in the greenhouse.
