Fusarium wilt–common bean pathosystem: Pathogen variability and genetic control

Crop Science, Volume 63, Issue 5, Page 2609-2622, September/October 2023., 2023
Abstract Sustainable management of plant diseases has been a challenge in the effort to feed a human population that has increased substantially. One of the main diseases that affect common bean and dry bean is Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. phaseoli (Fop), which can cause losses of up to 100% in crop production.

Interpretation of Microbial Soil Indicators as a Function of Crop Yield and Organic Carbon

Soil Science Society of America Journal, Volume 77, Issue 2, Page 461-472, March 2013., 2013
An interpretative framework for microbial biomass C (MBC), basal respiration, and the activity of soil enzymes cellulase, β‐glucosidase, arylsulfatase, and acid phosphatase was developed for the clayey Oxisols of the Brazilian Cerrado. Soil samples (0–10‐cm depth) were collected from 24 treatments from three long‐term experiments and analyzed to ...
