The chlamydospores of Fusarium oxysporum f. sp. pisi and F. solani f. sp. Pisi could germinate well in acid soil. The germination rate was reduced by increasing the soil pH. However, both wilt and root rot diseases were reduced only at pH 7.4, not at the range of pH 4.0 to 7.0. In greenhouse, adding different dosages of calcium cyanamide, S-H mixture and lime to the soil (pH 4.2), the pH values of both bulk and rhizosphere soils were raised, but the rhizosphere soil pH was neutralized to 6.0 to 7.0 with time. Calcium cyanamide could inhibit the wilt and root rot pathogens and diseases; S-H mixture could only inhibit the wilt pathogen and disease, but lime had no effect. In Hsin-sir experimental plots, the bulk soil pH values and both wilt and root rot pathogens were not changed very much by using soil amendments. In the plots of 1985, wilt disease was inhibited by calcium cyanamide and reduced by S-H mixture (product of Taiwan Fertilizer Company) and lime. In the plots of 1986, however, both calcium cyanamide and S-H mixture (home-made) could reduce the wilt disease, but lime had no effect. Soil pH seems not to be the main factor. More researches on the mechanisms of disease suppression need to be done in the future.
