soybean, glycine max, is susceptible to a large number of disease agents such as seedling and root pathogens that cause serious damages to this crop plant. one of these soil-borne pathogens is macrophomina phaseolina, the causal agent of charcoal root rot. in this study, two bacteria, pantoea agglomerans and bacillus sp. bin, and a fungus, trichoderma harzianum t100, as potential biocontrol age...

Seed composition in soybean [Glycine max (L) Merr.] has not been well investigated under charcoal rot infestation under irrigated and non-irrigated conditions. The objective of the present experiment was to assess seed composition and nitrogen fixation under these conditions. No significant differences in protein levels in the moderately resistant germplasm line DT97-4290 were observed under th...

In March 2014, a kohlrabi stem rot sample was collected from the cold storage room of Daegwallyong Horticultural Cooperative, Korea. White and fuzzy mycelial growth was observed on the stem, symptomatic of stem rot disease. The pathogen was isolated from the infected stem and cultured on potato dextrose agar for further fungal morphological observation and to confirm its pathogenicity, accordin...

charcoal rot caused by macrophomina phaseolina is an important disease of soybean throughout the world. to understand the spatial distribution of soybean charcoal rot incidence and m. phaseolina populations in golestan province, 172 soybean fields were surveyed for population density, in two successive years, and integrated with geographic information system (gis). each year, 60 fields were als...

Tea (Camellia sp) is one of the most economically important plantation crops and second-largest non-alcoholic beverage in world next to water being consumed by people different forms. It cultivated mainly Assam, West Bengal covering regions such as Darjeeling, Dooars, Terai, Southern India about 6.36 lakh hectares with a production 1338 million Kg made teas. Darjeeling tea world-famous for its ...

an experiment was carried out in 2008-2009 to study the correlation between the reaction to potassium chlorate and pathogenicity on some iranian isolates of macrophomina phaseolina, the causal agent of soybean charcoal rot. from among a total of 48 collected isolates from the major soybean cultivation areas of golestan, mazandaran, ardabil, and lorestan provinces, twenty four isolates were sele...

Nineteen safflower genotypes (Carthamus tinctorius L.) that originated from different geographical regions were screening for their response to infection with Macrophomina phaseolina, the charcoal rot pathogen at the research farm of Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran, in 2005. The plants were evaluated for length and width of necrotic lesion at the e...

Sunflower (Helianthus annuus L.) is one of the most important crops grown in world, but it can be attacked by more than 30 different pathogens. The areal Macrophomina phaseolina (Tassi) Goid., sunflower pathogens nowadays often found temperate regions, has been spreading over last few years due to climate change. effective eco-friendly method for controlling charcoal rot caused M. growing resis...

Sclerotinia sclerotiorum, the causal agent of Sclerotinia stem rot, is a devastating fungal pathogen of soybean that can cause significant yield losses to growers when environmental conditions are favorable for the disease. The development of resistant varieties has proven difficult. However, poor resistance in commercial cultivars can be improved through additional breeding efforts and underst...
