Abstract
Sclerotium cepivorum is a causal agent of white rot disease on different plants including Allium species such as garlic. A mycoparasite, Paraconiothyrium minitans S134 was selected for biological control of sclerotinia rot of garlic caused by S. cepivorum. The experiment was carried out in a garlic field in Taean from October in 2011 to June in 2012. Spore suspension of the mycoparasite was treated twice onto soil surface around garlic plants in sowing in 2011 and late Feb. in 2012, and disease rating was made June in 2012. Incidence of white rot in the twice-application plot of the mycoparasite ($5{\times}10^6$ spores/mL) and in the fluquinconazole (WP)-treated plot was 6.8% and 0.4%, respectively, whereas that of control was 19.5%. As the results, P. minitans S134 could be a prospective biofungicide for biological control of white rot of garlic.
