Abstract

This study was aimed to evaluate the biological control effectiveness of Trichoderma isolates against charcoal rot disease in melon (Cucumis melo cv. Kırkağaç-637). Macrophomina phaseolina (Tassi) Goid. is soilborne fungal pathogen that causes for considerable damages in melon production. In the study, the effectiveness of six previously known Trichoderma isolates on seed germination, plant growth and against M. phaseolina of melon in in-vitro and in-vivo was determined. As a result of the seed germination of melon tests carried out in-vitro condition, the seed germination occurred 80−100% on Trichoderma isolates, while 70% on control plates. In in-vivo study, when growth of plant was compared in treatments, the isolate of Tr28 was encouraged the fresh weight increase (77.68%) and root growth (177%) in comparison with the negative control. When Tr28+Mp15, Tr138B+Mp15 and R+Mp15 treatments increased the fresh weight, Tr28+Mp15, R+Mp15, Tr138B+Mp15, Tr55+Mp15 isolates increased the root weight in plants inoculated with M. phaseolina, and these applications showed the best effect compared to the positive control. The plant growth and effectiveness on M. phaseolina in 12.5 g/l Fludioxonil + 5 g/l Metalaxyl (Cebir) treatment, it was lower than Tr28+Mp15, Tr138B+Mp15 treatments.

Özet

Bu çalışma Trichoderma izolatlarının kavunda (Cucumis melo cv. Kırkağaç-637) kömür çürüklüğü hastalığına karşı biyolojik mücadele olanaklarının değerlendirilmesi amacıyla yürütülmüştür. Macrophomina phaseolina (Tassi) Goid. kavun üretiminde önemli kayıplara neden olan toprak kaynaklı fungal patojendir. Çalışmada etkinliği önceden bilinen altı Trichoderma izolatının kavunda tohum çimlenesi, bitki gelişimi ve M. phaseolina’ya karşı etkinliği in-vitro ve in-vivo’da belirlenmiştir. In-vitro kavun tohum çimlenme testi sonucunda Trichoderma izolatlarında %80−100 tohum çimlenmesi gerçekleşirken, kontrolde ise %70 oranında olmuştur. In-vivo çalışmasında; uygulamaların bitki gelişimine olan etkisi ele alındığında, Tr28 izolatı negatif kontrole göre %77.68 bitki yaş ağırlık artışı sağlayan ve %177 oranında kök gelişimini teşvik eden en iyi izolat olmuştur. M. phaseolina ile inokule edilen bitkilerde Tr28+Mp15, Tr138B+Mp15 ve R+Mp15 uygulamaları yaş ağırlık artışında, kök ağırlık artışında ise Tr28+Mp15 ve R+Mp15, Tr138B+Mp15 ve Tr55+Mp15 uygulamaları pozitif kontrole göre en iyi etkiyi göstermiştir. 12.5 g/l Fludioxonil + 5 g/l Metalaxyl (Cebir) uygulaması ise Tr28+Mp15, Tr138B+Mp15 göre bitki gelişimi ve M. phaseolina’ya karşı etkisi daha düşük olmuştur.
