One of the main concerns related to closed systems is potential spread root pathogens. With recirculation nutrient solutions. Ozone treatment was tested for efficacy against plant pathogen (Pythium), growth and yield cucumber crop grown in hydroponic system during summer season (June-August) 2022. Two solution feeding tanks were used one with ozone other without randomized complete design (RCD)...

In order to discover novel eco-friendly lead compounds for plant pathogenic fungi control, a series of benzaldehyde thiosemicarbazide derivatives with a piperidine moiety have been designed and synthesized. Fungicidal activities of all the synthesized compounds were evaluated in vitro. The results indicated that all the title compounds exhibited moderate to good fungicidal activities. Compound ...

We studied the diversity of oomycetes in a declining reed belt (Phragmites australis) of Lake Constance, Germany, using conventional baiting with specific reed and standard oak baits, accompanied by molecular techniques. Apart from an Aphanomyces sp. and a Phytophthora sp., baiting from reed rhizosphere samples from flooded, as well as drier, littoral sites revealed only Pythium spp. A total of...

Pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. Some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. Since 1968, when the first Pythium species was reported from Iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

In a 3-year-study, we analysed the population dynamics of the reed pathogen Pythium phragmitis and other reed-associated oomycetes colonizing fresh and dried reed leaves in the littoral zone of a large lake. Oomycete communities derived from internal transcribed spacer clone libraries were clearly differentiated according to substrate and seasonal influences. In fresh leaves, diverse communitie...

The oomycotaPythium oligandrumPo37 is used as a biocontrol agent of plant diseases. Here, we present the first draft of theP. oligandrumPo37 genome sequence, which comprises 725 scaffolds with a total length of 35.9 Mb and 11,695 predicted protein-coding genes.

The fungal flora of two water bodies Upper Lake and Hathaikheda Reservoir Bhopal Madhya Pradesh were isolated during the course study from January 2017 to December 2018. During present study, total 600 isolates, comprising 17 genera 24 species aquatic terrestrial fungi recorded bodies. These belonged various orders group Oomycota, Ascomycota Zygomycota. Members Saprolegniales dominant over rest...

The phylogeny of 116 species and varieties of Pythium was studied using parsimony and phenetic analysis of the ITS region of the nuclear ribosomal DNA. The D1, D2 and D3 regions of the adjacent large subunit nuclear ribosomal DNA of half the Pythium strains were also sequenced and gave a phylogeny congruent with the ITS data. All the 40 presently available ex-type strains were included in this ...
