Treater with spray system in coating of soybean seeds with aminoacid, fungicide, insecticide and polymer

Com o objetivo de avaliar o tratamento e o recobrimento de sementes de soja em um equipamento com sistema de aspers??o da marca Grazmec Spray System?? foi realizado um conjunto de experimentos na Faculdade de Agronomia Eliseu Maciel (FAEM) da Universidade Federal de Pelotas, campus do Cap??o do Le??o. Os tratamentos aplicados com o equipamento foram: 1) testemunha, 2) fungicida, 3) amino??cido, 4) pol??mero, 5) fungicida + amino??cido, 6) fungicida + inseticida, 7) fungicida + pol??mero, 8) fungicida + inseticida + pol??mero e 9) fungicida + amino??cido + inseticida. Para avaliar o sistema de aspers??o foi realizada a avalia????es de grau de umidade, emerg??ncia em campo, peso de 1000 sementes e cobertura das sementes. Para a determina????o da efici??ncia dos tratamentos foram realizadas avalia????es de germina????o, vigor, massa seca de plantas, desempenho inicial de plantas e sanidade de sementes. Ap??s tratadas, as sementes foram armazenadas por seis meses e avaliadas a cada 60 dias. Os resultados demonstraram que o aumento no grau de umidade das sementes de soja tratadas e/ou recobertas com o equipamento de sistema de aspers??o foi inferior a 1%. A emerg??ncia de pl??ntulas e o peso de 1000 sementes n??o foram afetados pelo tratamento e/ou recobrimento realizado com o sistema de aspers??o. Para que o recobrimento seja eficaz o equipamento deve ser regulado a cada mudan??a de produto e/ou semente. O uso de pol??mero melhora o recobrimento das sementes. A aplica????o do amino??cido isolado melhora a germina????o das sementes. A combina????o de amino??cido com fungicida, inseticida e pol??mero n??o melhora o desempenho das sementes. A aplica????o de fungicida + inseticida + pol??mero aumenta a ??rea foliar, massa seca de raiz e de parte a??rea das plantas quando comparada com a sem tratamento em sementes armazenadas por 4 meses ap??s o tratamento.The objective of this paper was to evaluate seed coating of soybean seed using equipment for treatment with spray system Grazmec??. The treatments applied with the equipment were: 1) control, 2) fungicide, 3) amino acid, 4) polymer, 5) fungicide + amino acid, 6) fungicide + insecticide, 7) fungicide + polymer, 8) fungicide + insecticide + polymer, 9) fungicide + amino acid + insecticide. The evaluation of the spray system was followed by moisture content determination, weight of 1000 seeds and coverage. Also field emergence was evaluated. The seed quality evaluations were followed by germination, vigor, dry matter of plants and seed health. The seeds were storage for six months and evaluations were done every 60 days. The results shows that soybean seed moisture content was 1% lower with the treatment; the field emergence and weight of 1000 seeds were no affected by treatment; when the change of product and/or seed the equipment should regulated for a coating good. The applied of polymer improve seed coating. The application of amino acid isolate improve the performance of the seeds; the use of amino acid combined with fungicide, insecticide and polymer do not improve the seed quality; the use of polymer fungicide + insecticide + polymer improve leaf area, dry mass of root and of part aerial of the plant compare with control in storage seed for four months after treatment
