Abstract
Lettuce leaves co-inoculated withSclerotinia sclerotiorum andConiothyrium minitans and controls were placed on, or buried in, soil for a period of two weeks to study development and survival ofC. minitans. OnS. sclerotiorum-infected leaves on the soil surface, the number of colonies ofC. minitans recovered was about 40% of the number of pycnidiospores applied. When buried in the soil there was a reduction to about 2% of the spores applied. WhenC. minitans was applied on healthy lettuce leaves, which were subsequently placed on or in soil, the recovery was about 4%. It is argued that these figures indicate multiplication ofC. minitans onS. sclerotiorum-infected lettuce leaves on the soil, and good survival in all other cases.
