Akdeniz ve Avrupa’nın
baharat bitkisi olan rezene (Foeniculum vulgare)
yemeklerde aroma ve tıbbi bitki olarak kullanılmaktadır. Rezene üretimi Burdur
ve ilçelerinde yaygın olarak yapılmaktadır. Ancak, geçen yıl ve bu yıl rezene üretim
alanlarında görülen fungal hastalık etmeni üretimi tehdit etmeye başlayınca
üreticiler tarafından laboratuvarımıza örnekler gönderilmiştir. Bu nedenle
hastalık etmeni fungusun tanılanması için çalışmalar gerçekleştirilmiş,
hastalık etmeni kültüre alındıktan sonra Koch postulatı uygulanmış ve uygun
mücadele yöntemleri hakkında tavsiyeler sunulmuştur. Mikroskobik çalışmalar
rezene bitkilerini hastalandıran etmenin Cercosporidium
punctum olduğunu göstermiştir. Bitki dokularında yanıklıklar şeklinde
belirtiler gösteren hastalık etmeni yüksek sıcaklık ve nemde kısa sürede salgın
oluşturabilmektedir. Hastalıkla mücadelede; hastalıktan ari sertifikalı tohum
kullanılmalı, varsa hastalığa dayanıklı çeşitler üretilmeli ve kültürel
uygulamalarla hastalığın gelişimi önlenmelidir.
Fennel (Foeniculum vulgare) is not only a valuable spice plant of Mediterranean and Europe but it has used for aroma and medicinal purposes in foods and industries respectively. Fennel production is common in Burdur province and its districts. However, last year and this year, fennel production areas were infected with a fungal disease. Fennel producers have brought samples to our laboratory. For this reason, studies have been conducted to diagnose the disease causing fungus, Koch postulates were conducted and appropriate management methods for the disease were recommended. Microscopic studies have revealed that a fungal pathogen, Cercosporidium punctum is the causal agent of the disease on fennel plants. The symptoms appear as blight on plant tissues. The fungal spores are able to cause epidemics under suitable high temperature and humidity conditions. The Cercosporidium blight disease should be controlled by using disease free seeds, disease-resistant varieties and appropriate cultural management methods. The development of the disease should be suppressed with cultural practices.Fennel (Foeniculum vulgare) is not only a valuable spice plant of Mediterranean and Europe but it has used for aroma and medicinal purposes in foods and industries respectively.
