Verbatim
e3βIn this paper, the activity of the compounds of C. rosea antagonistic to B. cinerea was assessed.β
e5βCompound(s) produced by the antagonist in culture medium inhibited the germination of conidia and the activities of sclerotia and mycelia.β
e7βWhen the C. rosea culture filtrate was applied to tomato stem segments at different times, the size of the lesion caused by the pathogen reduced.β

Other claims from this paper (6)
- Observation Clonostachys rosea does not produce volatile compounds that affect Botrytis cinerea.
- Intervention effect Compound(s) produced by C. rosea in culture medium inhibited conidial germination of Botrytis cinerea.
- Mechanism The inhibitory effect of the compounds on sclerotia and mycelia was fungistatic, because their activities resumed when transferred to medium without the compounds.
- Intervention effect Applying the C. rosea culture filtrate one day before or at the time of inoculation gave control efficiency higher than 90% against Botrytis cinerea on tomato stems.
- Intervention effect Applying the C. rosea culture filtrate one day before inoculation decreased lesion length by 50% on tomato stems.
- Mechanism C. rosea isolates most likely act through organic compound(s) that are deleterious to Botrytis cinerea by fungistasis.
