Abstract
The infection of Phaseolus vulgaris and Pisum sativum by Rhizoctonia solani and Pythium ultimum was reduced in our experiments by incorporating increasing quantities of domestic waste compost in a sandy loam soil inoculated with the higher mentioned pathogens.
In the biological control of soil borne plant pathogens use is also made of organic matter – though of vegetable origin – but a straight explanation for this precultural measure cannot be given because soil characteristics, as well as microflora, host plant and pathogen are influenced.
Next to extensive changes in the physical, physico-chemical and chemical characteristics of the soil one has to keep in mind the quantitative and qualitative shift in the soil microflora in which a reduced infection can be attributed to a changed pathogenicity and inoculum density of the pathogen as well as to a reduced predisposition of the host plant.
