Host Plant Resistance in Strawberries to Anthracnose and Colonization of Crown and Root Tissue by Verticillium dahliae and Macrophomina phaseolina
… production can be severely impacted by soilborne pathogens that can affect strawberry roots, crowns and leaves which can result in plant mortality. As much as 50 to 60% mortality can occur in one field. Pathogens responsible for such losses include <em>Colletotrichum acutatum …

Effect of soilpH and temperature on the biological control of Rhizoctonia solani by Bacillus megaterium and Trichoderma harzianum
… pH and temperature on the biological control of soilborne plant pathogens. In vitro experiments showed that T. harzianum isolate Th008 was antagonistic to R. solani and compatible to B. megaterium strain B153-2-2. Under greenhouse conditions, disease was more severe at soil pH 7.0 than 5.5 and at …

Improving Vegetable Soybean Production Through Investigating the Impact of Genotype and Environmental Factors on Germination and Emergence
… emergence. Moreover, environmental factors, pathogens and temperature, impact emergence. The study highlights that current edamame genotypes are commonly affected by soilborne pathogens, including Rhizoctonia solani, Athelia rolfsii, and Pythium irregulare, leading to seed rot and seedling …

Managing Weeds and Soilborne Pests with Fumigant and Non-Fumigant Alternatives to Methyl Bromide
… was widely used as a soil fumigant to manage soilborne pests in plasticulture vegetable production; however, it has been banned by the United Nations Environment Programme. Alternatives to MBr must be implemented to sustain fresh market tomato productivity. Possible MBr alternatives include …

Extracellular DNA-Based Trapping of Heavy Metals by Root Border Cells
… central role of the matrix in defense against pathogens and toxic metals was revealed by the discovery that its degradation by nuclease eliminates resistance of the root tip to infection and injury. Border cell exDNA traps immobilized phytopathogenic bacteria Ralstonia solanacearum, which were …

Perennial Grass Based Crop Rotations in Virginia: Effects on Soil Quality, Disease Incidence, and Cotton and Peanut Growth
… associated with differences in soil quality. Soilborne plant pathogens including root-knot nematode, stubby root nematode, ring nematode, stunt nematode, and Cylindrocladium parasiticum microsclerotia were measured in the spring and fall of each year to determine differences associated with …

Investigating Novel Approaches for the Integrated Control of the Soilborne Strawberry Pathogens Macrophomina phaseolina and Fusarium oxysporum f. sp. fragariae
… <em>fragariae</em> (<em>Fof</em>) are emerging soilborne pathogens causing crown rot and Fusarium wilt, respectively, in commercial strawberry production in California. Fungicides representing eight active ingredients from four different mode of action groups (FRAC groups 1, 3, 7 and 12) were …

Evaluation of Rhizoctonia solani - Heterodera glycines interactions on soybean
… cyst nematode (Heterodera glycines; SCN) are two soilborne pathogens that co-infest fields in soybean-producing states, contributing to significant yield reduction. Both pathogens infect the soybean radicle early in the growing season causing pre- and post-emergence stand reductions. The pathogens …

Biological wastes as plant growth substrate amendments
… in the transmission of human food-poisoning pathogens on raw vegetables and in fruit juices. The first part of this research was concerned with the evaluation of a biological control strategy for soil-borne pathogens, these are difficult to eliminate and the chemicals of which the most …
