Antagonistic effect of Aspergilus melleus Yukawa on soilborne pathogenes of chickpea

Nohut kök patojenlerinden Marcophomina phaseolina, Fusarium oxysporum f. sp. ciceri, F. solani, F. acuminatum, F. equiseti, F. moniliforme, F. sambucinum ve Rhizoctonia solani 'nin miseliyal gelişimi ve enfeksiyonu üzerine Aspergillus melleus Yukawa'nın etkisi çalışılmıştır. F. sambucinum, F. equiseti, R. solani, M. phaseolina, F. oxysporum f. sp. ciceri ve F. moniliforme'nin PDA üzerindeki koloni gelişmesi A. melleus tarafından önemli derecede (sırasıyla %52.2, 51.1, 46.6, 46.6, 46.3 ve 42.1) engellenmiştir. F. sambucinum, F. moniliforme, M. phaseolina, F. equiseti ve F. oxysporum f. sp. ciceri 'nin neden olduğu kök çürüklüğü ve solgunluk hastalığı A. melleus içeren topraklarda önemli ölçüde azalmıştır. Fakat A. melleus'un nohutlarda F. acuminatum and R. solani'nin enfeksiyonu üzerine hiç bir etkisi olmamıştır. A. melleus en fazla etkiyi M. phaseolina üzerinde göstererek bu etmenin neden olduğu enfeksiyonu % 72.78 oranında engellemiştir.

Toprak kökenli nohut patojenlerine Aspergillus melleus Yukawa' nın antagonistik etkisi

Effect of Aspergillus melleus Yukawa on mycelial growth and infection of chickpea by Marcophomina phaseolina, Fusarium oxysporum f.sp.ciceri, F.solani, F.acuminatum, F.equiseti, F.moniliforme, F.sambucinum and Rhizoctonia solani was studied. A. melleus inhibited the colony growth of F.sambucinum, F.equiseti, R.solani, M.phaseolina, F.oxysporum and F.moniliforme (52.2, 51.1, 46.6, 46.6, 46.3 and 42.1%, respectively) on PDA. Root rot and wilt diseases caused by F.sambucinum, F.moniliforme, M.phaseolina, F.equiseti and F.oxysporum f.sp.ciceri in A.melleus-amended soil were reduced significantly. However, there was no effect of A.melleus on infection by F.acuminatum and R.solani in chickpea. The highest reduction value was obtained with M.phaseolina (72.78%).
