Abstract
We hypothesized that foliar-applied fungicide for white mold (WM) management, especially when associated with partially resistant genotypes to WM, could reduce the incidence of common bean seed-borne Sclerotinia sclerotiorum. Seeds from three irrigated field trials with low/moderate, moderate or high WM pressure were evaluated using the Neon test. In these trials, genotype (partially resistant, intermediate resistant, or susceptible to WM) was combined with fluazinam (0, 1, 2, or 3 applications). The fungicide-genotype interaction was nonsignificant for the seed infection frequency of S. sclerotiorum, partially refuting our hypothesis. However, compared to no fungicide application, two applications resulted in a 6.5-fold reduction in the seed infection frequency, indicating that fungicide applications may contribute to reducing seed infection by this fungus.
期刊介绍：
Tropical Plant Pathology is an international journal devoted to publishing a wide range of research on fundamental and applied aspects of plant diseases of concern to agricultural, forest and ornamental crops from tropical and subtropical environments.
Submissions must report original research that provides new insights into the etiology and epidemiology of plant disease as well as population biology of plant pathogens, host-pathogen interactions, physiological and molecular plant pathology, and strategies to promote crop protection.
The journal considers for publication: original articles, short communications, reviews and letters to the editor. For more details please check the submission guidelines.
Founded in 1976, the journal is the official publication of the Brazilian Phytopathology Society.
