abstract valerian medicinal plant (valeriana officinalis) is a perennial succulent plant that is natural lenitive and good ingrained of diazepam. this study was conducted in order to identify the fungal agents of rhizome and root rot of valerian. infected plant samples that showed the symptoms of rotting and necrosis were collected from karaj and used in order to isolate disease agents. symptom...

Two molecularly identified tomato isolates, Trichoderma asperelloides Ta41 and Rhizoctonia solani Rs33, were characterized antagonistically evaluated. The dual culture technique showed that had a high antagonistic activity of 83.33%, while light microscope bioassay demonstrated the isolate over-parasitized pathogen completely. Under greenhouse conditions, application was able to promote plant g...

In January 2021, unusual outbreak of shoot rot symptoms was observed in young spikenard (Aralia cordata) plants growing vinyl greenhouses located Chuncheon and Yanggu, Gangwon Province, Korea. The initially appeared on shoots the at or above soil surface level. Later, infected wholly rotted blighted. incidence diseased investigated ranged from 5% to 30%. Eight isolates Rhizoctonia sp. were obta...

in this research, the effect of crops such as corn, wheat, sugar beet and clover as previous crop on incidence of leaf and crown wart disease of sugar beet was studied. in the first year, corn, wheat, clover and sugar beet were planted as previous crop in a randomized complete block design with four replications. the amounts of turnover of nitrogen to the soil due to crop residue and their effe...

The three tested herbicides and fungicides caused significant inhibitory effect on the growth of Fusarium solani Rhizoctonia causal common bean damping-off root-rot diseases compared with control treatment. This inhibition was gradually increased by increasing concentration fungicides. Moreover, fungus F. greatly affected than R. solani. Furthermore, were more efficient in this regard. There de...

This study was carried out to determine the anastomosis groups and disease severity of Rhizoctonia solani, which causes root collar rot in chickpea production areas Konya. A total eleven isolates spp. were obtained isolations made from plants surveys. examined microscopically grouped as multinucleate, binucleate according number nuclei. Ten multinucleate identified R. while one isolate sp. In p...

In a previous study, we identified a Streptomyces sp., A3265, as exhibiting potent antifungal activity against various plant pathogenic fungi, including Botrytis cinerea, Colletotrichum gloeosporioides, and Rhizoctonia solani. This strain also exhibited a biocontrolling effect against ginseng root rot and damping-off disease, common diseases of ginseng and other crops. In this study, we isolate...
