Conteúdo: |
Soybean rust caused by Phakopsora pachyrhizi is one of the most important diseases in Brazil and is a threat to soybean cultivation by causing substantial yield losses. Epidemiological studies in many parts of the world have shown a narrow relationship among health leaf area duration (HAD) and yield. To a better understanding of the damage caused by soybean rust, a field research was carried out in a soybean winter crop to evaluate some epidemiological aspects of this disease. Health leaf area duration (HAD) showed significant effects on the number of seeds per plant, on the 1000 seed weight, and on yield. However, it was not showed significant effect on the number of pods per plant, and in the number of not filled pods per plant. The area under disease progress curve (AUDPC) showed significant effect only on 1000 seed weight and on yield, although with less precision than HAD. The fungicides from triazol group and the mixture of triazol with strobilurin showed the best control of soybean rust. It was concluded that the reductions in soybean yield by soybean rust is caused by a reduction on HAD, which reduces the number of seeds per plant and the 1000 seed weight. |
