“…Inadequate application of chemical products on seeds can increase risks of deterioration of their physiological quality, due to possible phytotoxic effects. Salgado and Ximenes (2013) evaluated the effect of treatment of maize seeds with insecticides in different storage periods and concluded that seed treatment with insecticide and storage affect seed germination. According to these authors, the interaction of seed treatment and storage affect the number of ungerminated seeds.…”

The aim of this study was to investigate the effect of treatment with insecticides and fungicides on the physiological quality of corn seeds, classified in sizes, in different periods of storage. Seeds of the hybrid BM915 PRO, classified in two sizes (CH20/64 and CH24/64), were treated with a mixture of carbendazim + thiram (Derosal Plus®), pirimiphos methyl (Actellic®), deltamethrin (K-obiol®), and water (standard treatment). In addition to the standard treatment adopted by the company, treatments with clothianidin (Poncho®), thiamethoxam (Cruizer®), and fipronil (Shelter®) were added to the spray mixture. The seeds were stored in a non-climate-controlled environment in multi-ply paper packages. The physiological quality of the seeds was evaluated every ninety days over a period of 270 days by the germination test, cold test, and accelerated aging. Sanitary quality was also evaluated through the Blotter test. The physiological quality of seeds of the hybrid BM915 PRO is maintained up to ninety days of storage, regardless of the chemical treatment used and the size of the seeds. The addition of the insecticide to the standard treatment used in chemical seed treatment does not affect the action of the fungicides on the fungi in the seeds.

-The goal of storage is to maintain the characteristics that seeds have immediately after processing; however, when this is over longer periods, storage may cause loss in quality. The aim of this study was to evaluate the effect of treatment with insecticide and fungicide on corn seeds harvested in kernel form and in the ear over the time of storage in two environments for 360 days. The seeds were subjected to the following treatments: T1 -control; T2 -Deltamethrin + Pirimiphosmethyl + Fludioxonil; T3 -Deltamethrin + Pirimiphos-methyl + Fludioxonil + Thiamethoxam; T4 -Thiamethoxam, and T5 -Fenitrothion. They were then placed in paper bags and stored in two environments, in a cold room with an average temperature of 16 °C and RH of 60% and in a non-controlled environment (an average room temperature of 25 ºC and RH of 70%) located in the municipality of Pelotas, RS, Brazil. Every four months (0, 120, 240 and 360 days), seed germination and vigor was evaluated by the first count of germination test and cold test. Reduction in germination and vigor of corn seeds, conditioned by the insecticides and fungicide used in the seed treatment, vary according to the product and the time over which the seeds remain stored. The seeds harvested in the ear show lower loss of physiological quality than those harvested in kernel form.Index terms: Zea mays L., germination, vigor, seed treatment.Desempenho fisiológico durante o armazenamento de sementes de milho tratadas com inseticidas e fungicida RESUMO -O armazenamento tem por objetivo manter as características que as sementes possuem imediatamente após o beneficiamento, porém, quando por períodos mais extensos, o mesmo pode causar perdas na qualidade das mesmas. O objetivo neste trabalho foi avaliar o efeito do tratamento com inseticida e fungicida sobre sementes de milho colhidas a granel e em espiga durante o armazenamento em dois ambientes por 360 dias. As sementes foram submetidas aos tratamentos: T1-testemunha; T2-Deltamethrin + Pirimifós-metílico + Fludioxonil; T3-Deltamethrin +Pirimifós-metílico + Fludioxonil + Tiametoxam; T4-Tiametoxam e T5-Fenitrothion. Em seguida, foram acondicionadas em sacos de papel e armazenadas em dois ambientes: câmara fria com temperatura média de 16 °C e UR de 60% e em ambiente não controlado (câmara com temperatura média de 25 ºC e UR de 70%, localizada no município de Pelotas-RS). A cada quatro meses (0; 120; 240 e 360 dias) foi avaliada a germinação e o vigor das sementes, pelos testes de primeira contagem de germinação e teste de frio. A redução da germinação e do vigor de sementes de milho, condicionada pelos inseticidas e fungicida utilizados no tratamento das sementes, varia em função do produto e do tempo em que as sementes permanecem armazenadas. As sementes colhidas em espiga apresentam menor perda da qualidade fisiológica em relação às colhidas a granel.Termos para indexação: Zea mays L., germinação, vigor, tratamento de sementes.1

The objective of this work was to evaluate the effect of the industrial treatment with insecticides on the physiological quality of corn (Zea mays) seeds during storage at different temperatures. Seeds of the BM 950 PRO3 and BM 709 PRO2 hybrids were subjected to industrial treatment with insecticides based on chlorantraniliprole, cyantraniliprole, and clothianidin, as well as to a control, and stored at different temperatures (10, 20, and 30°C) for 0, 90, 180, 270, and 360 days, in a 4x3x5 factorial arrangement for each hybrid, in a completely randomized design. To evaluate the quality of the seeds, tests of moisture content, germination, seedling emergence, accelerated aging, and cold were performed. For the seeds of both hybrids, germination is preserved at minimum commercialization standards for up to 360 days of storage, regardless of the insecticide or storage temperature. The temperature of 10°C preserves seed vigor and minimizes the negative effects caused by the insecticides during storage. At 20 and 30°C, vigor is cumulatively impaired as storage is extended, mainly at 30°C. Chlorantraniliprole results in a greater preservation of seed vigor regardless of storage temperature, whereas clothianidin provides a greater loss of vigor in industrially treated corn seeds, especially when stored at 30°C.
