Damping-off, root rot and necrotic lesions were observed on sugar beet (Beta vulgaris) seedlings in the Kafrelsheikh Governorate, northern part of Nile River delta, Egypt. Pythium aphanidermatum was identified as causal agent using morphology asexual sexual morphs molecular studies. This is first record P.
Corn yield reduction following a cereal rye cover crop has been attributed to, among other factors, allelochemicals released from decomposing residue. The allelopathic effect of 6-methoxy-2-benzoxazolinone (MBOA) was evaluated on corn seedling growth, mycelial growth seven pathogenic species Pythium, and root rot seedlings caused by Pythium spp. at 13, 16, 22 to 23°C (room temperature) using pl...
سابقه و هدف: بیماری های کلزا از مهم ترین دلایل محدود کننده تولید کلزا محسوب می گردند. در دنیا، عوامل قارچی متفاوتی مانند rhizoctonia solani، pytium sp.، phytophthora sp. و fusarium sp. دلیل پوسیدگی ریشه و مرگ گیاه چه معرفی شده اند. هدف از این پژوهش شناسایی عوامل قارچی مولد پوسیدگی ریشه و طوقه کلزا در شهرستان مرودشت و تعیین گونه های غالب بیماری زا در سطح منطقه بود. مواد و روش ها: در این مطاله یک...
abstract a total of 270 bacillus strains were isolated from bulk soil and rhizospheric of cucumber in the tonekabon fields (mazandaran province). antifungal activity of bacillus strains was evaluated against pythium aphanidermatum and p. ultimum using dual culture method. 13 strains with more than 10 mm inhibition zone were selected for further study. morphological, physiological, biochemical a...
A cutaneous Pythium insidiosum reinfection was diagnosed in an equine in Brazil. Lesions with focal presentation appeared 2 years apart. The first infection and even immunotherapy were not likely to develop enough immune response to prevent reinfection. The use of adjuvants should be considered in the immunotherapy of pythiosis.
Root and stalk rot (RSR) of maize (Zea mays L.) plants, caused by soil-borne disease pathogens the genus Pythium, can get worse in global warming. It has been known that resistance F1 hybrids often disaccords with those their parental inbreds, which makes it difficult to develop resistant effectively. Best linear unbiased prediction (BLUP) is a standard mixed model equation, fitted for predicti...
