“…The same result was found by Dan et al (2010) and Castro et al (2008) that, when testing the Cropstar ® insecticide on soybean seeds, observed higher vigor from seeds treated with these insecticide even after 45 days of storage. The other products contributed Journal of Seed Science, v.38, n.4, p. [278][279][280][281][282][283][284][285][286]2016 to a reduction in the vigor.…”

-The timing of seed treatment application is important to keep soybean seeds quality. Therefore, the aim of this study was verify the effect of fungicides and insecticides treatment in soybean seeds quality before and after storage. Seeds of NS 7494, NS 8693 and NS 7338 IPRO were utilized and analyses separately, through a factorial scheme 3x6, with three application moments: treated and assessed; treated, stored and assessed; stored, treated and assessed; and six combination of fungicides and insecticides:

“…Porém, efeitos negativos no comprimento das raízes e de plântulas foram observados em sementes de soja tratadas com fipronil, acefato e thiametoxam (Dan et al, 2010). No trabalho, valores semelhantes ao da testemunha foram obtidos com o acephate, imidacloprid, [imidacloprid+thiodicarb] e thiametoxam+fipronil.…”

RESUMO -O tratamento de sementes com inseticidas é um método eficiente que auxilia o manejo integrado de pragas, porém, há escassez de informações de produtos que apresentem seletividade para a cultura do sorgo. O objetivo deste trabalho foi o de avaliar a influência do tratamento de sementes de sorgo com inseticidas, contendo um ou dois princípios ativos, sem e com o armazenamento por 30 dias, na fase inicial de desenvolvimento das plantas. O experimento foi conduzido na Fesurv-Universidade de Rio Verde, em Rio Verde-GO com dez inseticidas (thiodicarb, fipronil, acephate, thiametoxam, imidacloprid, [imidacloprid+thiodicarb], imidacloprid+thiodicarb, imidacloprid+fipronil, thiametoxam+thiodicarb, thiametoxam+fipronil, acrescido da testemunha sem inseticida) sem e com o armazenamento das sementes por 30 dias. Os resultados obtidos permitiram constatar que o armazenamento por 30 dias das sementes de sorgo tratadas com inseticidas diminui o percentual de germinação. A mistura imidaclopridrid+thiodicarb apresenta maior potencial para uso no tratamento de sementes de sorgo. O inseticida acephate causa fitotoxicidade às plântulas de sorgo ao contrário do fipronil, thiametoxam e a mistura thiametoxam+thiodicarb que não prejudicam o vigor das sementes de sorgo.Termos para indexação: Sorghum bicolor, fitotoxicidade, pragas. INSECTICIDE TREATMENT OF SORGHUM SEEDSABSTRACT -Seed treatment with insecticides is an effective tool in integrated pest management, but information on selective products to treat sorghum seeds is limited. The objective of this study was to evaluate the effects of treating sorghum seeds with insecticides containing one or two active ingredients, with and without storage for 30 days, on the early plant development. The experiment was conducted at Fesurv-Universidade de Rio Verde, in Rio Verde-GO, using ten insecticides (thiodicarb, fipronil, acephate, thiamethoxam, imidacloprid, [imidacloprid+thiodicarb], imidacloprid+thiodicarb, imidacloprid+fipronil, thiamethoxam+thiodicarb, thiamethoxam+fipronil, plus a non-insecticide control, with and without 30 day seed storage. The results showed that storage of sorghum seeds treated with insecticides for 30 days reduced the germination percentage. The imidacloprid+thiodicarb mixture has more potential for treating sorghum seeds. The insecticide acephate causes more phytotoxicity to the sorghum seedlings compared to fipronil, thiamethoxam and the thiamethoxam+thiodicarb mixture. The insecticides did not adversely affect sorghum seed vigor.

-The objective of this experiment was to evaluate responses of soybean cultivars seeds (with different levels of lignin) considering harvest postponement under the incidence of water and the effect of storage. The experiment was conducted in Iraí de Minas, Brazil using a randomized block design with three replications under a 5 x 3 x 3 factorial arrangement, with five soybean cultivars (NK 7059 RR, SYN 1163 RR, SYN 9070 RR, AS 7307 RR and SYN 1283 RR), three harvesting periods (R8, R8 + one rain simulation in the pre-harvesting period and R8 + two simulations in the pre-harvesting period) under three storage times (0, 90 and 180 days). Seeds were evaluated for their chemical composition (lignin contents), the percentage of moisture damage using the tetrazolium test and physiological quality (germination, accelerated aging, conductivity test, seedling emergence and emergence index). Cultivar AS 7307 RR had the highest lignin content in the integument, the lowest percentage of damage by moisture and the highest physiological quality. Cultivars NK 7059 RR and SYN 1163 RR had the lowest lignin contents in the integument and the highest moisture damage. Electrical conductivity increased after storing all cultivars.Index terms: Glycine max, lignin, storage.Qualidade fisiológica de sementes de soja submetidas à chuva artificial na pré-colheita RESUMO -Objetivou-se com este trabalho avaliar o desempenho de sementes de cultivares de soja com diferentes teores de lignina considerando o retardamento da colheita sob incidência artificial de chuva, e ao longo do armazenamento. O ensaio foi conduzido em Iraí de Minas, MG, em blocos casualizados com três repetições e esquema fatorial 5 x 3 x 3, sendo cinco cultivares de soja (NK 7059 RR, SYN 1163 RR, SYN 9070 RR, AS 7307 RR e SYN 1283 RR), três épocas de colheita (R8, R8 + uma simulação de chuva na pré-colheita e R8 + duas simulações de chuva na pré-colheita), e três épocas de armazenamento (0, 90 e 180 dias). As sementes foram avaliadas quanto à composição química (teor de lignina), porcentagem de danos por umidade usando o teste de tetrazólio, e a qualidade fisiológica (germinação, teste de envelhecimento, condutividade elétrica, emergência, índice de emergência). A cultivar AS 7307 RR apresentou maior teor de lignina no tegumento, menor porcentagem de danos por umidade e melhor qualidade fisiológica. As cultivares NK 7059 RR e SYN 1163 RR apresentam menores teores de lignina no tegumento e maiores danos por umidade. Os valores de condutividade elétrica aumentam com o armazenamento para todas as cultivares.Termos para indexação: Glycine max, lignina, armazenamento.
