Interpretive Summary:

Technical Abstract: Cover cropping can improve soil quality by increasing soil organic matter, elevating microbial activity, and augmenting nutrient and water retention. However, if the cover crop is a host for soilborne pathogens, then its cultivation could lead to an increased risk of disease. Here, new research is presented on the ability for cover crops to host Macrophomina phaseolina and impact soil populations of this pathogen. Known risks associated with cover cropping and their impact on populations of Fusarium oxysporum f. sp. fragariae and Verticillium dahliae are also reviewed. Cereals are not good hosts for any of these pathogens and are therefore recommended as an inexpensive option for winter cover cropping after strawberry production.
