Vaccinium myrtillus ve Inula viscosa BİTKİ EKSTRAKTLARININ Monilinia fructigena’ya KARŞI KONTAK AKTİVELERİ ÜZERİNE BİR DEĞERLENDİRME

Bitki patojenlerinin kontrol edilmesinde kullanılan sentetik kimyasal ilaçların insan ve çevre sağlığı üzerine etkilerinin en alt düzeye indirilebilmesi için bitkisel ekstraktların kullanımı alternatif bir yöntem değerlendirilebilir. Bu çalışmayla; Vaccinium myrtillus (Yaban mersini) ve Inula viscosa (Yapışkan andız otu) bitkilerinin toprak üstü kısımlarından elde edilen methanol ekstraktının Monilinia fructigena (Honey in Whetze) üzerine antifungal aktivitesi in vitro koşullarda araştırılmıştır. Ekstraktların patojene karşı aktiviteleri agar petri yöntemi kullanılarak ile 1,33 mg/ml, 2 mg/ml ve 2,66 mg/ml dozların da belirlenmiştir. Ekstraktların patojenlerin miselyum gelişmeleri (MG) ve miselyum gelişim engellemeleri (MGE) hesaplanmıştır. Monilinia fructigena’nın miselyum gelişim engelleme üzerine I. viscosa ekstraktının 2,66 mg/ml dozda %74,42 V. myrtillus ekstraktının ise %57,92 oranında etkili olduğu belirlenmiştir. V. myrtillus ve I. viscosa bitki methanol ekstraktlarınında Monilinia fructigena’ya karşı in vitro koşullarda miselyum gelişimi üzerine etkili olduğu belirlenmiştir. Monilinia fructigena üzerine I. viscosa ekstraktının V. myrtillus ekstraktına göre daha etkili olduğu belirlenmiştir. Yürütülen çalışma, bitki patojenlerinin kontrolünde bitki ekstraktlarının kullanımının değerlenmesi için katkı sağlayacaktır.

AN EVALUATION ON THE CONTACT ACTIVITIES OF Vaccinium myrtillus and Inula viscosa PLANT EXTRACTS AGAINST Monilinia fructigena

The use of herbal extracts can be considered as an alternative method to minimize the effects of synthetic chemical pesticide used in the control of plant pathogens on human and environmental health. This study; Antifungal activity of methanol extract obtained from above ground parts of Vaccinium myrtillus (Blueberry) and Inula viscosa (False yellow head or Strong-Smelling Inula) plants on Monilinia fructigena (Honey in Whetze) was determined in vitro conditions. The pathogen activity of the extracts was determined by using agar petri method at doses of 1.33 mg/ml, 2 mg/ml and 2.66 mg/ml. Mycelial growth (MG) and mycelial growth inhibition (MGE) of pathogens of extracts were calculated. Monilinia fructigena on inhibition the development of mycelium; a dose 2.66 mg/ml dose, 74.42% of I. viscosa extract and 57.92% of I. myrtillus extract was determined to be effective. V. myrtillus and I. viscosa plant methanol extracts against Monilinia fructigena in vitro conditions were determined to be effective on the development of mycelium. Monilinia fructigena on I. viscosa extract was found to be more effective than V. myrtillus extract. The study, will contribute to the evaluation of the use of plant extracts in the control of plant pathogens.
