The objective of this study was to evaluate the health quality of soybean seeds cv. Coodetec 217, in two harvesters operating at different speeds and in different collection places in the machine. The treatment consisted of two machines (Massey Ferguson, 2003 and Massey Ferguson, 2004), two speeds (4 Km.h-1 and 7 Km.h-1) and two collection places (grain tank and unloading exit). The analyses were realized at the Laboratory of Phytopathology at FCAV/UNESP, Campus of Jaboticabal, SP, Brazil. The seeds were analyzed by the Blotter test with four repetitions of 50 seeds. There was significant interaction for the factors machines and collection places for the incidence of Penicillium sp. and Fusarium sp., among machines and speed for Aspergillus spp., and among speed and collection places for Penicillium sp.. The presence of fungi associated to the seeds, mainly, Cladosporium sp. and Fusarium sp. did not depend on the machine type. Smaller contamination in general was verified in the seeds collected from the unloading exit and at the speed of 4 Km.h-1. For Fusarium sp., Aspergillus spp., and Penicillium sp. there was a dependence of the factors on their incidences in the seeds of the cultivars analyzed, under the studied conditions.
