Root parsley protection against damping off

Myxobacteria exert partial control of damping-off and root disease in container-grown tree seedlings.

Damping-off of Sweetgnm by Pythium sylvaticum

During the spring of 1964, preand postemergence damping-off killed many sweetgum (Liquidambar styraciftua L.) seedlings in a nursery at Stoneville, Miss. Fusarium solani (Mart.) Appel & Wr., Sclerotium rolfsii Sacc., Talaromyces spiculisporum Benjamin, and Pythium sylvaticum Campbell & F.F.Hendrix were isolated from the diseased seedlings. At soil temperatures similar to those prevailing when d...

Control Efficacy of Streptomyces sp. A501 against Ginseng Damping-off and Its Antifungal Substance

Ginseng damping-off, caused by the fungal pathogens Rhizoctonia solani and Pythium sp., is a critical disease in ginseng seedling. In a continuing effort to find microorganisms with the potential of acting as a biocontrol agent against Rhizoctonia damping-off, we found that a Streptomyces sp. A501 showed significant antifungal activity against Rhizoctonia solani. In field experiment to test the...

In vitro Evaluation of Biocontrol Agents Against Damping Off Disease Caused by Pythium debaryanum on Tomato

Damping-off diseases incited by different species of Pythium are a persistent problem worldwide, often resulting in reduced yields and occasionally resulting in major crop damage. There have been increasing restrictions on the use of chemical fungicides, and the development of disease-suppressive biocontrol agents has become a major goal of horticulture crops. An experiment was conducted with t...

Cardiac protection takes off.

Protecting the heart from ischaemiaand reperfusioninduced injury represents the greatest challenge of cardiology, since myocardial infarction is the major cause of mortality in industrialized countries. Research on cardiac protection has a long history in the discovery of new principles of protection, replete with triumphs but also broken dreams with respect to their clinical application. Treat...
