Then the extent of infestation on the undersides of the leaves was visually determined.
  • Leaves of potted tomato plants were sprayed to drip point with an aqueous suspension in the drug concentration below. After three days, the leaves were infected with an aqueous sporangia suspension of Phytophthora infestans. Subsequently, the plants were placed in a water vapor-saturated chamber at temperatures between 18 and 2O 0 C. After 6 days, the late blight on the untreated but infected control plants had developed so strongly that the infestation could be determined visually in%.
