- Abstract
The sweet potato, Ipomoea batatas (L.) Lam., is a highly productive crop, successfully acclimatized in Romania. Worldwide, in countries where sweet potato is a traditional crop, a wide range of plant pathogens is mentioned. In Romania, a few phytopathogenic infections have been encountered for this culture. However, Fusarium incidence on sweet potato increased in the last years. In the present paper the symptomatology of sweet potato fusariosis is described. The aim of the study is to reveal the biocontrol potential of a Romanian native strain of Bacillus subtilis in reducing Fusarium spp. growth. Bacterial physiologic studies have shown that the strain uses several mechanisms to inhibit fungal growth. In vitro tests showed an efficiency of 31.3 to 51.4% for the growth inhibition of phytopathogenic fusaria.
