Ramularia collo-cygni is a fungal agent that causes Ramularia leaf spot disease on barley (Hordeum vulgare). It causes necrotic spotting and premature leaf aging, leading to loss of green leaf area in barley, and in case of an epidemic, it causes yield loss up to 70%. Although it was defined more than a hundred years ago due to the late emergence of the disease and the difficulty of diagnosis, it has been accepted as an important pathogen of barley in recent years. Today, it attracts a lot of attention by researchers due to the epidemics it creates around the world. This review describes in detail the biology, epidemiology, host-pathogen relationships of this fungal agent, which has not yet been detected in Turkey and summarizes the current control strategies.

Önemli Bir Arpa Patojeni: Ramularia collo-cygni

Öz

Ramularia collo-cygni, arpada (Hordeum vulgare) Ramularia yaprak lekesi hastalığına neden olan fungal bir etmendir. Nekrotik lekelenmeye ve erken yaprak yaşlanmasına neden olarak arpada yeşil yaprak alanı kaybına yol açmakta ve epidemi yapması durumunda %70’e varan verim kaybına neden olmaktadır. Hastalığın geç dönemde ortaya çıkması ve etmenin tanısının zorluğu nedeni ile yüz yıldan fazla süre önce tanımlanmış olmasına rağmen son yıllarda, arpanın önemli bir patojeni olarak kabul edilmiştir. Günümüzde dünya çapında meydana getirdiği epidemiler nedeni ile araştırmacılar tarafından oldukça ilgi görmektedir. Bu derleme, ülkemizde henüz tespiti yapılmamış olan bu fungal etmenin detaylı olarak biyolojisi, epidemiyolojisi, konukçu patojen ilişkilerini tanımlamakta ve mevcut kontrol stratejilerini özetlemektedir.
