Other claims from this paper (13)
- Observation Rhizopus sp. was the most pathogenic isolate among the tomato postharvest fungi, followed by Fusarium sp.
- Observation In dual plate tests, clear zones of T3 and T24 against postharvest pathogens of tomato were 1 to 4 mm and 3 to 6 mm.
- Observation T3 and T24 showed no inhibition zone against Rhizopus sp. in dual plate tests.
- Observation T3 and T24 overgrew Rhizopus sp. by 100% after 9 days of incubation.
- Intervention effect T3 showed a higher degree of overgrowth of the other postharvest isolates than T24.
- Observation The two antagonists failed to overgrow Aspergillus species, except T3 overgrew A. niger (3).
- Intervention effect Volatile and non-volatile metabolites of T3 and T24 significantly inhibited mycelial growth of Penicillium stekii more than the other tested pathogens.
- Observation Metabolites of T24 inhibited A. niger (1) by 97% after 3 days.
- Observation Volatile compounds of T3 and T24 inhibited Aspergillus sp. by 2% and 20%, respectively.
- Observation Non-volatile compounds of T3 and T24 inhibited Aspergillus sp. by 75% and 87%, respectively.
- Observation T. harzianum isolates T3 and T24 gave a complete protection of tomato slices from infection by the tested pathogens.
- Observation Trichoderma suppressed linear growth of the tested pathogens on tomato slices by 80 to 100% after 3 days, significantly.
- Observation Trichoderma suppressed Rhizopus sp. on tomato slices by only 33% after 3 days.
