Batı Karadeniz Bölgesiʼnde fasulye köşeli yaprak lekesi hastalığının kimyasal mücadelesi üzerinde araştırmalar

Year 2015, Volume: 55 Issue: 2, 0 - 0, 30.06.2015

Abstract

Fasulyede köşeli yaprak lekesine neden olan Pseudocercospora griseola ülkemizde ilk defa Zonguldak ili Çaycuma ilçesinde tespit edilmiştir. Hastalık etmeni bu bölgedeki yerel genotiplerde ciddi zararlara neden olmuştur. Hastalık önce yapraklarda küçük köşeli lekelerle başlamakta sonra hızla tüm yaprakları tamamen kurutmakta, kapsüllerde derin kahverengi yaralara neden olmaktadır. Hastalığa karşı ülkemizde kimyasal mücadele tavsiyesi olmadığından bölge üreticileri için üründe ciddi verim kayıpları ve maddi kayıplar ortaya çıkmaktadır. Bunun yanı sıra üreticiler her yıl yine kendi tohumlarını kullandıkları için hastalıklı tohumların inokulum oranını yıldan yıla arttırdığı ve diğer yakın bölgelere de hastalığın yayıldığı gözlenmiştir.

Bu çalışma ile yerel olarak yetiştiriciliği yapılan fasulye genotiplerinde köşeli yaprak lekesi hastalığına neden olan P. griseola’nın kimyasal mücadele olanakları araştırılmıştır. Kimyasal mücadele çalışmaları tohum ilaçlaması ve yeşil aksam ilaçlaması şeklinde yürütülmüştür. Denemeler Zonguldak ilinin Çaycuma ve Gökçebey ilçelerinde 2010, 2011 ve 2012 yıllarında yürütülmüştür. Hastalıkla mücadelede Difenoconazole, Azoxystrobin ve Mancozeb etkili maddeli ilaçlar en yüksek etkiyi göstermişlerdir.

Chemical control possibilities of angular leaf spot disease caused by <em>Pseudocercospora griseola</em>, on common beans in Western Black Sea Region

Year 2015, Volume: 55 Issue: 2, 0 - 0, 30.06.2015

Abstract

Pseudocercospora griseola, the causal agent of angular leaf spot, caused important damage in domestic varieties and was first identified in Çaycuma district of Zonguldak province in Turkey. This pathogen has caused serious damage on local bean genotypes in the province. The disease begins as angular spots on leaves which is followed by quick death of leaves and it causes deep brown wounds on capsules. Since chemical control is not recommended for the disease in Turkey, it causes severe yield and economic losses. Besides, because the producers use domestic seeds, the infected seeds will increase the inoculum source year by year and distribute the disease to close by provinces.

With this project, chemical control possibilities of P. griseola that is the causal agent of angular leaf spot in locally grown bean genotypes were investigated. Chemicals were applied as seed treatment and foliar spraying.

The trials were carried out in Çaycuma and Gökçebey the district of Zonguldak in 2010, 2011 and 2012. Difenoconazole, Azoxystrobin and Mancozeb showed the highest impact in control of the disease.
