BACKGROUND Pythium ultimum is a plant pathogen that causes significant yield losses on many economically important crops. Chemical treatment has been used for disease control. In searching for alternatives, venom piperidine and piperideine alkaloids from red imported fire ants were tested against P. ultimum in vitro, and piperideines were employed to control cucumber damping-off in the greenhou...

Seed decay (rot) and seedling damping-off caused by Rhizoctonia solani are among the most important diseases of cotton which result in the significant yield reduction, application of expensive and harmful chemical fungicides and most importantly contamination of soil and agricultural environment. This study was conducted to investigate the possible efficacy of cotton seed delinting in the reduc...

salinity stress is one of the most important abiotic factors that restrict the growth and yield of many plants. salinity can increasingly influence the host susceptibility, occurrence and development of plant diseases due to its negative effects on the host plants. mycorrhizal fungi are able to increase the tolerance of some plants to salinity. in this study, the biological effects of glomus mo...

in this research, the antagonistic effects of bacillus subtilis isolates against the causal agent of tomato damping-off, rhizoctonia solani were surveyed under laboratory and greenhouse conditions. isolates b4 and b18 showed the most inhibition ratio in the volatile and non-volatile metabolites tests which were 50.3% and 58.6% respectively. the six out of 25 isolates studied more and their anta...

Rhizoctonia solani causes economically important root and hypocotyl diseases in common bean throughout the world. Root health is a vital factor in plant development and root diseases would negatively influence water and nutrient uptake as well as cause direct stand reduction and root rot damage to the crop. An efficient common bean screening method to evaluate damping-off and early root/ hypoco...

Soybean (Glycine max (L) Merr.) seed treatments are recognized as useful in reducing losses from seed borne pathogens and seedling damping off agents. The seed treatment with fungicide is essential in the improved technology for increasing crop production. In the present investigation two seed protectant fungicides captan and carbendazim are used. Effect of fungicides on growth of Rhizobium jap...

to determine the role of fusarium species associated with sugar beet root  and crown rot, diseased samples were collected  from different fields of sugar beet in iran including khorasan, khuzestan west azarbayejan, qazvin, tehran, kermanshah ,kerman,lorestan ,hamedan,charmahal va bachtiary provinces during growing seasons 1999-2002. in total, 94 isolates of fusarium were obtained. based on morp...
