Sclerotium cepivorum

Disease-resistant varieties are attractive because they should pose little or no risk to the environment and enable growers to reduce and in some cases eliminate the need for pesticides. In some host-pathogen systems, resistance may persist for many years, but in others it may be short-lived (Koike et al., 2000). Unfortunately, resistance is not available to counter every disease and for some of the most damaging ones, such as tomato late blight (P. infestans) and white rot (Sclerotium cepivorum) of alliums, no acceptable resistant varieties are currently available.

Adding S. fruticosa Mill. (Lamiaceae) compost to soil decreases the high C/N rates and raises the pH of the soil. Moreover, it increases the number of microbes in the soil, such as bacteria and fungi (Chalkos et al, 2010). S. sclarea (Lamiaceae) volatile oil s compounds are linalyl acetate, linalool, geranyl acetate, and a-terpineol. The essential oil is able to cause fungicidal activity on S. sclerotiorum, a soilborne pathogen. It also inhibits growth of Sclerotium cepivorum and Fusarium oxysporum f.sp. Dianthi (Pitarokili et al., 2002).
