ABSTRACT Pseudomonas spp. are ubiquitous bacteria in agricultural soils and have many traits that make them well suited as biocontrol agents of soilborne pathogens. Tremendous progress has been made in characterizing the process of root colonization by pseudomonads, the biotic and abiotic factors affecting colonization, bacterial traits and genes contributing to rhizosphere competence, and the ...

The root-knot nematode, Meloidogyne incognita, and the soilborne fungus Thielaviopsis basicola, the causal agent of black root-rot, are important plant pathogens of cotton in Arkansas. When M. incognita and T. basicola occur in the same field, greater damage may occur on cotton than when only one of the pathogens is present. Studying the relationship of soil factors on M. incognita Monfort et a...
