Compost Tea as a Container Medium Drench for Suppressing Seedling Damping-Off Caused by Pythium ultimum.
ABSTRACT Compost tea is being used increasingly in agricultural production to control plant diseases. However, there has been limited investigation relating disease control efficacy to various compost tea production methods, particularly compost tea produced with active aeration and additives to increase microbial population densities in compost tea. Aerated compost tea (ACT) and nonaerated com...
متن کاملبررسی تاثیر سودوموناسهای فلورسنت روی قارچ Pythium ultimum Trow عامل پوسیدگی بذر لوبیا
در سالهای اخیر بحث امکان کنترل بیولوژیکی خاکزاد مورد توجه جدی محققین قرار گرفته است که از آن جمله می‌توان به باکتریهای آنتاگونیست بخصوص از باکتریهای گروه سودوموناسهای فلورسنت در کنترل بیماری‌های قارچی و باکتریایی ریشه گیاهان زراعی اشاره کرد. میکروارگانیسم‌هایی که در ناحیه ریزوسفر گیاهان زندگی می‌کنند گزینه مناسبی برای استفاده در روش‌های کنترل بیولوژیکی هستند زیرا ریزوسفر خط مقدم دفاعی ریشه‌ها ع...
متن کاملProduction of the polyunsaturated fatty acids arachidonic acid and eicosapentaenoic acid by the fungus Pythium ultimum.
Several strains of species of the fungal genus Pythium, and of Phytophthora cinnamomi, were screened for content of the polyunsaturated fatty acids (PUFAs) arachidonic acid (AA) and eicosapentaenoic acid (EPA). The aim of the investigation was to establish alternative sources of these PUFAs, which are of importance in human nutrition. As a relatively prolific producer of EPA and AA, P. ultimum ...

متن کاملCellular and Molecular Mechanisms Involved in the Interaction between Trichoderma harzianum and Pythium ultimum.
The interaction between Trichoderma harzianum and the soilborne plant pathogen Pythium ultimum was studied by electron microscopy and further investigated by gold cytochemistry. Early contact between the two fungi was accompanied by the abnormal deposition of a cellulose-enriched material at sites of potential antagonist penetration. The antagonist displayed the ability to penetrate this barrie...
