Keywords: Damping off, lesions, macroconidia, Phaseolus vulgaris L. Gibberella zeae Schw. The succession wheat-soybean, wheat-bean or wheat-corn crops are the main economic alternative for production systems in the South region of Brazil. However, succession of crops may exert a selection pressure on F.
Because F. In bean, F. However, the parasitism of F. Thus, the objective of this work was to verify the pathogenicity of F. The evaluated treatments were: seeds without inoculation of Fusarium graminearum T1 - control and with inoculation of F. Using wheat seeds cv. After seven days of incubation, colonies with similar characteristics to F. Creole bean seeds, disinfested as previously described, were inoculated with 1 mL-1 of macroconidia suspension, at the final concentration of 8.
Seeds of both varieties, corresponding to the control treatment, received only 1 mL-1 of distilled and sterilized water. After inoculation of seeds, the following tests were conducted: For the germination test, seeds with inoculation of the pathogen and seeds without inoculation were used for each variety of creole beans.
Each treatment was divided into four replicates of 50 seeds, seeded in filter paper moistened with distilled water in the proportion of 2. For the disease severity index and damping off quantification in each variety, 8 replicates with 25 seeds per treatment were used, seeded on germinating paper and moistened with 2.
