THE BEHAVIOUR OF TOMATO PATHOGENS IN A HYDROPONIC SYSTEM |
| Authors: | W.P. Staunton, T.P. Cormican |
| Abstract:
Five pathogens were tested for their ability to cause disease in tomatoes grown in nutrient solution. The pathogens were Fusarium oxysporum f. sp. lycopersici, Didymella lycopersici, Phytophthora nicotianae, Pyrenochaeta lycopersici and Corynebacterium michiganense. The inoculum used was both in the form of pure cultures from artificial media and diseased tomato plant parts. Tomatoes were grown in the pathogen-infested nutrient solution for four months during which disease development was monitored. Though rapid spread of disease through the nutrient solution might be expected this did not happen. Present indications are that this method of growing tomatoes does not pose any extra disease hazard over that of growing in other media. | |
