One of the major diseases shallots is basal rot disease caused by Fusarium oxysporum f.sp. cepae (FOC). Biocontrol agents can be used as an environmentally friendly control method. Some yeasts isolated from rhizosphere may have potencies to soilborne plant pathogen such FOC. This study was objected obtain yeast isolates that rot. The first step isolation and were then tested for their in suppre...

in order to investigate the effects of drought stress and nitrogen fertilizer on photosynthesis rate and some physiological characteristics in two barley cultivars, a pot experiment was conducted using a randomized complete block design as a factorial experiment with three factors including water stress, nitrogen fertilizer and barley cultivars in three replications. irrigation treatments condu...

triploidy in grass carp, ctenopharyngodon idella valenciennes, 1844, was induced on fertilized eggs to compare cold and heat shocks. two simplified methods explained for verification of triploidy in grass carp. the cold shock (7 ?c) was given in three treatments for 30 min starting 2.0, 2.5 and 4.0 min after fertilization. in cold shock, the start point (2.0 min after fertilization) showed the ...

The present study was carried out to evaluate the effects of thymol and carvacrol supplementation on performance, immune response, antioxidant enzyme activity and blood parameters of heat stressed broilers. Broilers were fed with commercial diet till 25 d of age, then they were allocated to a completely randomized design with a 3 × 2 factorial arrangement with 6 treatments including 3 levels of...

Wide international interest in heat treatments for maintenance of postharvest quality, disease control, and as a quarantine technology, was reflected in the range of papers presented at this BARD Workshop on Postharvest Heat Treatments. Heat treatments are currently used commercially in several countries, for example as hot water dips, hot water brushing techniques, and hot air treatments. Rese...

Epiphytic yeasts, which colonize plant surfaces, may possess activity that can be harnessed to help plants defend themselves against various pathogens. Due to their unique characteristics, epiphytic yeasts belonging to the genus Pseudozyma hold great potential for use as biocontrol agents. We identified a unique, biologically active isolate of the epiphytic yeast Pseudozyma aphidis that is capa...

this experiment was performed to investigate the effects of propolis and chromium picolinate on performance and immune response of broiler chicken under heat stress conditions. treatments included different levels of propolis (500, 1000, and 1500 mg/kg) and chromium picolinate (1500 µg/ kg) along with a control group. a completely randomized design was taken into account with 4 replicates of 10...

German cockroaches (GCRs), Blattella germanica (L.) (Dictyoptera: Blattellidae), are attracted to those beer semiochemicals (e.g., ethanol) that formerly living and active yeasts have produced or otherwise formed in the brewing process. We predicted that an earlier step in the production of beer, where yeasts actively metabolize the sugar in malted barley powder (dry malt extract [DME]), is ver...

Economic losses caused by postharvest diseases represent one of the main problems of the citrus industry worldwide. The major diseases affecting citrus are the "green mold" and "blue mold", caused by Penicillium digitatum and P. italicum, respectively. To control them, synthetic fungicides are the most commonly used method. However, often the emergence of resistant strains occurs and their use ...
