Mycorrhizae,tems. Most cultivated plant species can be infected by mycorrhizal fungi. Depending on the host plant and the infecting fungus, different mycorrhizae are formed: ectomycorrhizae, ericaceous, orchidaceous, and vesicular- arbuscular mycorrhizae (VAM). The main importance for plant production within th

The Soil Environment,al, germination, host infection, growth within and outside the host, and reproduction, are affected directly and indirectly by the environment. The environment also influences the tissue growth, three-dimensional arrangement, physiological hardiness, and disease proneness of the host plant. Knowledg

Estimating Disease Severity and Incidence,ed easily once symptoms or signs become visible; however, it is the quantification of the disease that presents the challenge. The assessment of disease incidence (i.e., the number or proportion of diseased plants in a population) is an apparently simple counting task, but is subject to the usual li

Biological Management,nment must be considered in development of management systems for soilborne pathogens. The most successful systems exploit aspects of each member of the tetrad resulting in the maximum benefit to crop production with a minimum expenditure of resources.
