CAMILO, Giselli L. et al. Physiological quality of soybean seeds during storage after coating with agrochemicals. Rev. de Ciências Agrárias [online]. 2017, vol.40, n.2, pp.180-189. ISSN 0871-018X.  https://doi.org/10.19084/RCA16145.

The protection of seeds against pests and diseases in the early stages of crop development is of great importance to the soybean production chain. Coating seeds with insecticides and fungicides provides this protection; however, it should not cause damage to the physiological quality of seed lots, immediately after coating or after storage. To evaluate the effect of soybean seed coating with various agrochemicals on the physiological quality of seeds during storage, two assays were conducted with the cultivars M6972 IPRO and M7739 IPRO. Twenty kilograms of each cultivar were subjected to coating with products Cropstar, Derosal Plus, Standak Top and Avicta Completo, evaluating the first counting of germination, germination, accelerated aging and seedling emergence of seeds for 60 days of storage under environmental conditions. Storage under not controlled conditions of temperature and relative humidity negatively influences the physiological quality of soybean seeds. The cultivars used responded differently to the seed coating with different agrochemical tested. Soybean seed coating of cultivar M6972 IPRO with Standak Top or Avicta Completo maintains the percentage of seedling emergence during the 60 days of storage. Soybean seed coating of cultivar M7739 IPRO with Standak Top brings better physiological seed quality than other coatings.
