Characterization and pathogenicity of Rhizoctonia isolates collected from Brassica oleracea var. acephala in Ordu, Turkey

İsmail ERPER

A total of 30 Rhizoctonia isolates were collected from plants with Rhizoctonia-like symptoms in kale growing areas in Ordu province during the 2014-2015 growing seasons. All the isolates were identified using nuclear staining tecnique and the nucleotide sequence analysis of the nuclear rDNA internal transcribed spacer (ITS)1-5.8S-ITS2 region. The most prevalent anastomosis group (AG) was AG 2-1 (36.67?f isolates), followed by AG-A (30? AG 4 HG-I (10? AG 5 (6.67? AG-Fb (6.67? AG-E (6.67?and AG-K (3.33? Cultural characteristics showed that randomly selected RsCB-13 (AG 2-1), RsCB-20 (AG 4 HG-I), ...Более

Efficacy of the entomopathogenic fungi; Beauveria bassiana and Metarhizium anisopliae against the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae)

İsmail ERPER

The efficacy of the two entomopathogenic fungi, Metarhizium anisopliae (TR 106) and Beauveria bassiana (TR 217), was tested against the adults of the cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Chrysomelidae: Bruchinae) in laboratory. Two concentrations of conidial suspensions (1 x 10(6) and 1 x 10(8) conidia/ml) of M. anisopliae and B. bassiana isolates were directly applied on four pairs of adult beetles in Petri dishes (2 ml/dish) and then incubated at two different climatic regimes; 22 +/- 1 degrees C and 26 +/- 1 degrees C with 70 +/- 5% RH, 16:8 h light-to-dark. Lethal time v ...Более

The utility ofTrichodermaspp. isolates to control ofXylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae)

İsmail ERPER

The invasive ambrosia beetle,Xylosandrus germanusBlandford (Coleoptera: Curculionidae: Scolytinae), is a serious pest of hazelnut in Turkey, which is the biggest hazelnut producer in the world. In this study, the utility of four isolates representing differentTrichodermaspecies (T. harzianum,T. hamatum,T. asperellum, andT. atroviride) was evaluated on survival, gallery behavior and brood production ofX. germanusby effecting the symbiotic fungal development at laboratory conditions. Hazelnut branches were exposed to fungal suspensions (1 x 10(6)and 1 x 10(8)conidia mL(-1)doses) for about 30 s. ...Более

Potasyum Karbonat ve Bikarbonatın Sclerotium oryzae’nin Misel Gelişimi Üzerine Antifungal Etkisi

İsmail ERPER

Bu çalışmada, potasyum karbonat (PK) ve potasyum bikarbonat (PBK)’ın Sclerotium oryzae’nin misel gelişimi üzerindeki antifungal etkinliği in vitro koşullarda araştırılmıştır. Tuzların fungusun misel gelişimi üzerine antifungal etkisi %0.05, 0.10, 0.25, 0.50, 0.75 ve 1.0 (w/v) konsantrasyonları kullanılarak belirlenmiştir. In vitro testler, artan PK ve PBK konsantrasyonlarının kontrol ile kıyasla fungusun misel gelişimi üzerindeki engelleyici etkileri arasında önemli farklılıklar olduğunu göstermiştir (P
