Summary Strawberry tissues infected with Phytophthora cactorum were comminuted and plated in a selective antibiotic agar medium to determine levels of tissue colonisation as indicated by the number of colony forming units (CFU) recovered per gramme o

Summary A range of metal ions and the oxoanion WO42-were toxic to zoospores of Phytophthora nicotianae parasitica in the order: Ag+ > Cu++ > WO42-> Ni+ > Co++ > Zn+. The LD50 for Ag+, 0.11 μM (11.4 ppb), compared with 1.84 μm (117 ppb) for Cu++. Si

Summary The spatial and temporal colonisation of tomato plants by Phytophthora cryptogea was studied in rockwool nutrient culture. Root growth and the distribution and progress of infection were measured on dissected root fragments obtained from a de
