Czech bitter varieties were evaluated between 2010 and 2022. Hop displayed an average content of alpha acids 10.24% w/w (Agnus) 13.73% (Gaia). Variability below 15%, proved good stability in all tested bittering hops. All showed a decrease the over period 13 years hop cultivation. The highest beta was determined Gaia (7.30% w/w). In contrast, lowest found Rubín (3.73% new genotypes Uran 5304 ha...

Trichoderma an endophytic fungus used agriculture as biological control agent (BCA) and plant growth promoter. It has been to antagonize other crops. The objective current study was identify indigenous field isolate...

Cultivation of common hop (Humulus lupulus L.) has increased dramatically during the past decade, with primary growth occurring in Pacific Northwest United States. A major limitation to production is powdery mildew [caused by Podosphaera macularis (Wallr.) Braun & Takam]. To date, a comprehensive evaluation wild germplasm resources for resistance yet be conducted. Herein, we report first extens...

American foulbrood caused by Paenibacillus larvae brings with it several problems on beekeepers for the use of synthetic antibiotics, likewise led to appearance resistant strains and presence chemical residues in commercial products hive. In recent years, natural compounds control P. has increased. Herein, we propose determine value Minimal Inhibitory Concentration (MIC) a hydroalcoholic extrac...
