In vitro effect of methanol extract on spore germination of B.
cinerea and P. capsici. The concentrations of methanol extract
from 6.25 to 400 mg/mL all showed inhibitory effect on the spore
germination of B. cinerea and P. capsici, and there was a liner
relationship between log10-transformed concentration of methanol
extract and probit-transformed inhibitory rate on the spore and protective effect (Fig. 4). The methanol extract at 1000 mg/mL
exhibited 77.35% therapeutic effect and 71.57% protective effect on
detached tomato fruits infected with B. cinerea, which were similar to
the therapeutic effect and protective effect of the cell-free filtrate and
the chemical control (50% Sumilex, 10003). For both the therapeutic
effect and protective effect treatment, tomato fruits sprayed with the
methanol extract (1000 mg/mL), the cell-free filtrate and 50%
Sumilex (10003) showed only small legions while fruits sprayed
with water showed large lesions (Fig. 5).
