Incidência de Sclerotinia sclerotiorum em sementes de soja e sensibilidade dos testes de detecção
[Incidence of Sclerotinia sclerotiorum on soybean seeds and sensitivity of detection tests]

Abstract: The objective of this work was to evaluate the efficiency of detection methods of Sclerotinia sclerotiorum on soybean seeds. Experiments were carried out during three crop years, using samples of soybean seeds artificially and naturally contaminated, with known pathogen incidence on samples and on the field. The incubation methods used were: filter paper, paper roll, and Neon-S medium. An increase in pathogen detection on artificially contaminated seeds was observed, as the incidence in the sample increased. The methods may not detect the pathogen S. sclerotiorum on naturally contaminated soybean seeds. The levels of pathogen incidence on soybean seeds interfere in the sensitivity of the detection methods, and there is no relationship between the incidence on the field and on the harvested seed.
