Scoping study to investigate management of root-rot diseases in parsley
This item contains key sections of the final report on project VG04025, which involved identification of the cause and control of a root rot disease that severely affected parsley crops in Queensland, NSW and Victoria. Field trials conducted on a commercial crop of parsley in Victoria identified two fungicides which completely controlled the disease. These fungicides are from different chemical groups, therefore their use should conform to management of chemical resistance strategies. Parsley root rot in Victoria was associated with the water mould fungi Pythium and Phytophthora. The disease is prevalent during the late autumn and winter, especially after heavy rains when soil temperatures are low. Further work was recommended to determine if the control measures identified for Victorian crops will also control root rot in Queensland during the wet season.
