Abstract
This study was carried out to determine the alternative weed hosts of Fusarium spp. in potato fields in Erzurum province. Isolations were made from 15 weed species (Amaranthus retroflexus, Anchusa arvensis, Avena fatua, Centaurea depressa, Chenopodium album, Cirsium arvense, Convolvulus arvensis, Euphorbia spp., Hibiscus trionum, Lallemantia canesces, Linum bienne, Malva grandfolia, Polygonum lapathifolium, Sinapis arvensis and Tragopogon buphthalmoides) and 83 isolates of Fusarium were obtained from roots and/or stems of the weeds. These isolates were recognized as Fusarium equiseti, Fusarium oxysporum, Fusarium solani, Fusarium acuminatum and Fusarium avenaceum in the rates of 44.6%, 37.3%, 12.1%, 4.8% and 1.2% respectively. As a result of pathogenicity test conducted on potato plants (cv. Marfona), F. oxysporum and F. solani isolates were found to have the highest disease severity.
Özet
Bu çalışma, Erzurum ilinde patates tarlalarında Fusarium türlerinin alternatif yabancı ot konukçularını belirlemek amacıyla yürütülmüştür. Çalışmada 15 yabancı ot türünden (Amaranthus retroflexus, Anchusa arvensis, Avena fatua, Centaurea depressa, Chenopodium album, Cirsium arvense, Convolvulus arvensis, Euphorbia spp., Hibiscus trionum, Lallemantia canesces, Linum bienne, Malva grandfolia, Polygonum lapathifolium, Sinapis arvensis ve Tragopogon buphthalmoides) izolasyon yapılmış ve 83 Fusarium izolatı bitkilerin kök ve/veya gövdelerinden elde edilmiştir. Bu izolatların %44.6’sı Fusarium equiseti, %37.3’ü Fusarium oxysporum, %12.1’i Fusarium solani, %4.8’i Fusarium acuminatum ve %1.2’si Fusarium avenaceum olarak tanılanmıştır. Marfona patates çeşidi ile kurulan patojenisite denemesinde F. oxysporum ve F. solani izolatlarının en yüksek hastalık şiddetini oluşturduğu tespit edilmiştir.
