Suppressive Soil Reduces Carnation Disease
Fusarium wilt diseases caused by various specialized forms of the fungus Fusarium oxysporum Schlecht. do not occur or are restricted in some, field soils. These soils are designated Fusarium wilt-suppressive as contrasted to Fusarium wilt-conducive soils in which the disease readily develops. The wilt-suppressive soil used in this study was a Chualar sandy loam obtained from a cultivated field near Soledad, California.
