A new host for Fusarium algeriense causing crown and root rot on barley in Kyrgyzstan

Sezim COLDOŞBEKOVA | İsmail ERPER

After maize, wheat and rice, barley is the most widely planted and economically important cereal crop in the Kyrgyzstan's highlands (Usubaliev et al., 2013) and worldwide. In two barley fields in the Manas district of Bishkek, Kyrgyzstan, diseased plants exhibiting crown and root rot, stunting and brown discolouration on internodes were observed in 2020. Disease incidence was approximately 5 in the two fields.Small sections of root and crown tissues from diseased plants were surface sterilised in 1 (v/v) sodium hypochlorite solution for one minute before being placed onto potato dextrose agar ...Daha fazlası

Fungal Pathogens Associated with Crown and Root Rot in Wheat-Growing Areas of Northern Kyrgyzstan

İsmail ERPER | Şenol YILDIZ | Sezim COLDOŞBEKOVA | Tair Esenalı Uulu

Fungal species associated with crown and root rot diseases in wheat have been extensively studied in many parts of the world. However, no reports on the relative importance and distribution of pathogens associated with wheat crown and root rot in Kyrgyzstan have been published. Hence, fungal species associated with wheat crown/root rot were surveyed in three main wheat production regions in northern Kyrgyzstan. Fungal species were isolated on 1/5 strength potato-dextrose agar amended with streptomycin (0.1 g/L) and chloramphenicol (0.05 g/L). A total of 598 fungal isolates from symptomatic tis ...Daha fazlası

Sensitivity of Fusarium oxysporum f. sp. melongenae, the causal agent of Fusarium wilt of eggplant to some ammonium, potassium, and sodium compounds in vitro and in vivo bioassays

İsmail ERPER

This study evaluated the efficacy of various salts against Fusarium oxysporum f. sp. melongenae (Fomg) in vitro and in vivo bioassays. Ammonium bicarbonate/carbonate, potassium benzoate/sorbate, sodium benzoate/carbonate/metabisulphite at 2.0 entirely halted mycelial growth and spore germination of the fungus. Considering the EC50, minimum inhibitory concentration, and minimum fungicidal concentration values of the salts, sodium metabisulphite was more toxic to the fungus. In soil bioassays, at 0.4 and 0.6, sodium metabisulphite and potassium sorbate reduced the mycelial growth of the fungus b ...Daha fazlası

First Report of Crown Rot Caused by Fusarium algeriense on Wheat in Kyrgyzstan

İsmail ERPER

Fusarium crown rot of wheat is an economically important disease that leads to significant yield and quality losses, especially in arid and semiarid wheat-growing areas worldwide. In June 2020, winter wheat (Triticum aestivum L.) plants exhibiting crown rot symptoms were identified in a commercial field in Tokbay (43.033719°N, 74.325623°E), Chuy Province, Kyrgyzstan. Diseased plants were stunted and had brown discoloration on internodes of the stem bases and roots. Disease incidence was ∼3%. Ten plants from the field were sampled at the ripening stage to identify the causal agent. Symptomatic ...Daha fazlası

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. ...Daha fazlası
