Rhizoctonia solani is an important root infecting pathogen of a range of food staples worldwide including wheat, rice, maize, soybean, potato, legumes and others. Conventional resistance breeding strategies are hindered by the absence of tractable genetic resistance in any crop host. Understanding the biology and pathogenicity mechanisms of this fungus is important for addressing these disease ...

Rare earth elements have been tested in control of plant diseases. Lanthanum (La) was the Alternaria solani (in vitro) and tomato early blight vivo) using concentration 0; 0.1; 0.2; 0.4 0.8 g L-1. In vitro, were diluted V8 culture medium evaluated for mycelial growth rate index (MGRI) pathogen sporulation. vivo, 24 hours after application inoculate inoculation, leaflets collected quantification...
In order to discover new compounds with good fungicidal activities, 32 pyrazole derivatives were designed and synthesized. The structures of the target compounds were confirmed by 1H-NMR, 13C-NMR, and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), and their fungicidal activities against Botrytis cinerea, Rhizoctonia solani Kuhn, Valsa mali Miyabe et Yamada, Thanatephorus...
Rhizoctonia solani is a causative agent of sheath blight, which results in huge economic losses every year. During its life cycle, the formation of sclerotia helps Rhizoctonia solani withstand a variety of unfavorable factors. Oxidative stress is a key factor that induces sclerotium formation. The differentiated and undifferentiated phenotypes of R. solani AG-1-IA were obtained by controlling a...
در شهریور 1389 از طوقه و ریشه گیاهان لوبیای سالم و بیمار (دارای علائم پوسیدگی ریشه و طوقه) در مزارع لوبیای مناطق مهم لوبیا کاری استان زنجان و خاک ریزوسفر آن ها نمونه برداری انجام و اقدام به جداسازی و شناسایی عامل بیماری از ریشه و نیز جداسازی تریکودرماها از ریزوسفر این گیاهان گردید. در نتیجه مهم ترین عوامل بیماری fusarium solani و rhizoctonia solani شناسایی گردیدند و 132جدایه خالص تریکودرما نیز ...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
The impact of 10 Fusarium species in concomitant association with Rotylenchulus reniformis on cotton seedling disease was examined under greenhouse conditions. In experiment 1, fungal treatments consisted of Fusarium chlamydosporum, F. equiseti, F. lateritium, F. moniliforme, F. oxysporum, F. oxysporum f.sp. vasinfectum, F. proliferatum, F. semitectum, F. solani, and F. sporotrichioides; Rhizoc...
Background & Aim: By increasing resistance of fish pathogens to chemical drugs, using herbal plants with antimicrobial properties is necessary.In this study, the composition of the essential oil and antimicrobial activity of aerial parts of Achillea wilhelmsii C.Koch growing wild in Zagross mountain (Southwest of Iran) was analyzed against common bacterial and fungal pathogens of fish....
