residues on the soil surface to retard soil erosion, insulate the soil, and conserve soil moisture. This residue consists of leaves, leaf sheaths, ear husks, and stalks of corn that decompose very slowly on the soil surface. The relationship of surface residue to corn diseases can be divided into two categories: (1) a source of inoculum of disease-causing organisms, and (2) environment modifica...

Free-living protozoa may harbor, protect, and disperse bacteria, including those ingested and passed in viable form in feces. The flagellates are very important predators on bacteria in soil, but their role in the survival of food-borne pathogens associated with fruits and vegetables is not well understood. In this study, we investigated the interactions between a common soil flagellate, Cercom...

The area used to grow high-value crops is currently decreasing because production in the same soil for many years increases soil-borne diseases that reduce crop yield and quality as well farmer income. Soil-borne disease effectively controlled by fumigation prior planting. In this study, five different types of soils had been tomatoes, watermelon, cucumber, ginseng ginger were collected from fi...

Abstract Fusarium wilt ( oxysporum f.sp. cepae) is the most important soil-borne disease in garlic. This pathogen a weak parasite so that it can be controlled through healthy plant cultivation approaches such as use of organic compost fertilizer and soil microbes biological control agents. Gliocladium sp. an antagonist fungus used borne agent. study aims to evaluate effectiveness plus garlic ro...

Irrigation of vegetables during both air and soil-born drought has very positive effect on growth, development and yield. The impact of irrigation on the metabolism of plants is very complex because the increase in soil moisture affects plant physical, chemical and biological properties. Increasing the amount of water in the soil increases its heath capacity. Irrigated (wet) soil is cooler in s...

Brassica seed meals (BSMs) are widely used as biofumigants to control various soil-borne plant diseases. However, the mechanism of bacterial community reconstruction following fumigation with BSMs remains poorly understood. In present study, decipher in fumigated soil and understand effect communities on rhizosphere recruitment subsequent disease control, we investigated bulk using field experi...

The agents (pathogens) that cause soilborne diseases of peanut are various fungi and nematodes that survive in the soil and infect one or more parts of the plant at or below the soil surface. Soilborne diseases can severely limit peanut yields in Oklahoma, particularly in fields where long rotations with nonhost crops are not practiced. Southern blight and Sclerotinia blight are probably the mo...

Plant diseases cause dramatic yield losses worldwide. Current disease control practices can be deleterious for the environment and human health, calling for alternative and sustainable management regimes. Soils harbour microorganisms that can efficiently suppress pathogens. Uncovering mediators driving their functioning in the field still remains challenging, but represents an essential step in...

Recently, emission of volatile organic compounds (VOCs) has emerged as a mode of communication between bacteria and plants. Although some bacterial VOCs that promote plant growth have been identified, their underlying mechanism of action is unknown. Here we demonstrate that indole, which was identified using a screen for Arabidopsis growth promotion by VOCs from soil-borne bacteria, is a potent...

BACKGROUND Intercropping systems could increase crop diversity and avoid vulnerability to biotic stresses. Most studies have shown that intercropping can provide relief to crops against wind-dispersed pathogens. However, there was limited data on how the practice of intercropping help crops against soil-borne Phytophthora disease. PRINCIPAL FINDINGS Compared to pepper monoculture, a large sca...
