AGUIAR, Carlos E. et al. Physiological performance of hybrid corn seeds submitted to treatment with insecticide, fungicide and nutrients. Rev. de Ciências Agrárias [online]. 2018, vol.41, n.2, pp.61-70. ISSN 0871-018X.

The seed treatment is a major component of the integrated management of pests and diseases, which results in better establishment of cultures, reflecting positively on grain yield. Furthermore, it is expected to be effective, safety and low cost. This study aimed to identify options for treatment of maize seed best suited to storage without compromising seed quality. Seeds of two corn hybrids were used, which were subjected to 5 treatments: T1-Cropstar + Fertiactil GR; T2-Cropstar + Fulltec More; T3-Cropstar + Maxfertil Semental; T4-Cropstar and T5- control treatment. After treated, the seeds remained in storage with an average temperature of 20 to 22 °C and relative humidity average of 70 to 80%. It was evaluated the physiological quality through germination and seedling weight immediately after treatment and at 21, 35, 50, 72 and 99 days of storage. The treatment of corn seed with insecticide and nutrients applied alone or combined does not compromise the physiological quality up to 99 days after application. Further testing is required to evaluate the productivity of hybrids under the effect of these treatments.
