Natural Mechanisms of Soil Suppressiveness Against Diseases Caused by Organic matter (OM) and compost can be very effective in reducing pathogens such as species of Fusarium, Phytophthora, Pythium, and Rhizoctonia Suppressive organic matter or compost constitutes suppressive soils to form a three-way interaction between microorganisms on OM or compost, plant pathogen, and plants for natural biological control of
Chapter 17 - Compost use for plant disease suppression It was discovered that specific microorganisms in the rhizosphere of plants (the interface between plant roots and surrounding soil) can reduce the severity of diseases on the entire plant In a study from Germany, composted cow manure applied to soil with small grains and grapes suppressed powdery and downy mildew, respectively
Disease-suppressive compost enhances natural soil suppressiveness . . . Soil suppressiveness is defined as the natural ability of soil to suppress soil borne pathogens and support root growth While natural soil suppressiveness is quite effective against opportunistic pathogens such as the root rot fungal complex (Pythium sp , Rhizoctonia sp , Fusarium sp , Ilyonectria sp , etc ), it is much less effective in controlling specific pathogen-host systems such as the
Soil and Phytomicrobiome for Plant Disease Suppression and . . . - MDPI Green manure, especially from Brassica crops, can control weeds and alleviate plant diseases caused by pathogens in Rhizoctonia, Verticillium, Sclerotinia, Phythophthora, Pythium, Aphanomyces, and Macrophomina [123]
Disease Caused by Pythium - Department of Plant Pathology and . . . Pythium infections are usually limited to the meristematic root tips, root epidermis, cortex of roots, and fruits; but occasionally, severe infections occur when the pathogen moves deeper into the plant tissue and reaches the vascular system They are important pathogens that cause root rot of several crops in hydroponic culture (18)
Organic Production: Suppressing Soil-borne Pathogens — Plant Pest . . . Organic Production: Suppressing Soil-borne Pathogens Pathogens such as Fusarium, Pythium, Phytophthora, Thielaviopsis and Rhizoctonia that cause pre- and post-emergent damping-off can cause serious problems in organic (and conventional) transplant production
Soilborne Disease Management in Organic Vegetable Production Fungal, plasmodiophorid, oomycete, and bacterial pathogens, as well as viruses and plant parasitic nematodes, may all cause soilborne diseases Important soilborne fungal pathogens are species of Fusarium (Fig 1), Rhizoctonia (Fig 2), Verticillium, and Sclerotinia (Figs 3–5)
Common Strategies to Control lt;i gt;Pythium lt; i gt; Disease - J-STAGE Pythium species are soil-borne pathogens which can cause serious economic loss worldwide and threatening agricultural production Traditional management methods like chemical fungicides are effective against Pythium spp But as people pay more attention to human health and environmental issues, alternative methods that are ecofriendly and harmless to health are urgently needed Currently
A comprehensive review on biochar against plant pathogens: Current . . . Plant pathogens cause a serious menace to food production The diseases caused by pathogens are estimated to cause a yield loss of about 14 1 %, whereas, in India, up to 26 % Several plant pathogens like Pythium, Phytophthora, Rhizoctonia, Sclerotinia, Fusarium, and Verticillium can cause 50–75 % yield losses in cereals, cotton, and horticultural crops (fruits, vegetables, and flowers) 10
