| Abstract: | The sensitivity of Plasmopara-isolates to metalaxyl was determined by a leaf disc test. For the first time this permitted the distinction and clear characterization of not only sensitive and resistant isolates but also of isolates belonging to a third type of sensitivity, termed the reduced sensitive type. |
