Phytophthora and Pythium are a group of Oomycetes that widely associated with diseases in potato plants. Therefore, this study was conducted to identify the rhizosphere infected plants showing leaf blight. Four isolates were collected from four regions Central Java (UGM_St_TM, UGM_St_BK, UGM_St_BNJ, UGM_St_KJ, isolate Temanggung, Bakal, Banjarnegara, Kejajar respectively), UGM_St_NG as culture ...

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...
