Resumo: | The use of chemical seed treatment is an important tool in the protection of seedlings and has contributed to the increase of rice yield (Oryza sativa L.). The objective of this study was to evaluate the physiological quality and quantify the retention of chemical products in rice seeds treated with insecticide and fungicide coated with polymers. Six seed treatments were used: control, phytosanitary treatment and phytosanitary treatment and coating with the polymers, Florite 1127®, GV5® Solid Resin, Polyseed CF® and VermDynaseed®. The physiological quality was evaluated by the test of germination and vigor by first count tests, germination speed index, shoot length, radicle length, seedling dry mass and sand emergence. To determine the retention of the active ingredients metalaxyl-M and thiamethoxam, an equipment called extractor was used. The experiment was organized in a completely randomized design (DIC) and the averages were separated by the Scott Knott test (p≤0.05). Seed treatment with the fungicide and insecticide, coated with the polymers, Florite 1127®, Solid Resin GV5®, Polyseed CF® and VermDynaseed®, did not affect the physiological quality of rice seeds. Solid Resin GV5®, Polyseed CF® and VermDynaseed® polymers were efficient at retaining thiamethoxam in the rice seeds, preventing some of the active ingredients of the insecticide from being leached through the sand columns immediately after the simulated pluvial precipitation. |

Objetivou-se avaliar a qualidade fisiológica e quantificar a retenção de produtos químicos em sementes de arroz tratadas com inseticida e fungicida recobertas com polímeros. Foram utilizados seis tratamentos de sementes: controle, tratamento fitossanitário e tratamento fitossanitário e recobrimento com os polímeros, Florite 1127®, Resina Sólida GV5®, Polyseed CF® e o VermDynaseed®. A qualidade fisiológica foi avaliada pelo teste de germinação e vigor pelos testes de primeira contagem, índice de velocidade de germinação, comprimento de parte aérea, comprimento de radícula, massa seca de plântulas e emergência em areia. Para determinar a retenção dos ingredientes ativos metalaxil-M e thiamethoxam, utilizou-se equipamento denominado extrator. O experimento foi organizado no delineamento inteiramente casualizado (DIC) e as médias foram separadas pelo Scott Knott (p≤0,05).O tratamento de sementes com o fungicida e inseticida, recobertos com os polímeros,Florite 1127®, ResinSolid GV5®, Polyseed CF® e o VermDynaseed®, não afetaram a qualidade fisiológica de sementes de arroz. Os polímeros ResinSolid GV5®, Polyseed CF® e o VermDynaseed® foram eficientes na retenção do thiamethoxam junto às sementes de arroz, impedindo que parte do ingrediente ativo do inseticida fosse lixiviado, através das colunas de areia, logo após a precipitação pluvial simulada.Universidade Federal Rural do Semi-Árido2017-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/645710.1590/1983-21252017v30n412rcREVISTA CAATINGA; Vol. 30 No. 4 (2017); 920-927Revista Caatinga; v. 30 n. 4 (2017); 920-9271983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/6457/pdfCopyright (c) 2017 Revista Caatingainfo:eu-repo/semantics/openAccessFagundes, Lovane KleinNunes, Ubirajara RussiPrestes, Osmar DamianFernandes, Tiéle StukerLudwig, Eduardo JoséSaibt, Nathália2023-07-20T11:31:59Zoai:ojs.periodicos.ufersa.edu.br:article/6457Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:28.709575Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
