Resumo: | Seed treatment is a practice that helps the initial establishment of the crop without the effects caused by pests and diseases. The association of diazotrophic bacteria with grasses has been used in the supply of nitrogen to plants; however, these microorganisms produce growth-promoting substances, which promote benefits in the growth and development of the crops. Thus, the objective of this study was to evaluate the compatibility of Azospirillum brasilense associated with the fungicide difenoconazole and the insecticide thiamethoxam by observing the effects on the quality of seed emergence of three wheat cultivars (Triticum aestivum L.). Three wheat cultivars, arranged in a 4 x 2 factorial system with four replicates, were tested. The treatments were the control; difenoconazole (Spectro® at a dose of 150 mL per 100 kg of seed); thiamethoxam (Cruiser® FS 350 at a dose of 200 mL per 100 kg seed) and difenoconazole + thiamethoxam, applied on wheat cultivars TBIO Mestre, TBIO Itaipu and TBIO Sinuelo. Bacteria from the Azospirillum genus were used in the inoculation. The wheat seed retains its quality when it checks the germination, vigor and independent accelerated aging, whether or not fungicide, insecticide and A. brasilense were used. The insecticide thiamethoxam increased the length of shoots and roots and provided compatibility with A. brasilense, and fungicide inhibited the length of shoots and roots and was antagonistic to the bacterium A. brasilense. |

A associação de bactérias diazotróficas com gramíneas tem sido empregada no aporte de nitrogênio para as plantas, entretanto esses microrganismos produzem substâncias promotoras de crescimento, que promovem benefícios no crescimento e desenvolvimento das culturas. Dessa forma, objetivou-se com esse estudo avaliar a compatibilidade do Azospirillum brasilense associado ao fungicida difenoconazole e inseticida thiamethoxam, observando o efeito sobre a qualidade de emergência de sementes de três cultivares de trigo (Triticum aestivum L.). Foram testadas três cultivares de trigo, arranjadas em fatorial 4 x 2 com quatro repetições. Os tratamentos utilizados foram testemunha; difenoconazole (Spectro® na dose de 150 mL por 100 kg de semente); thiamethoxam (Cruiser® 350 FS na dose de 200 mL por 100 kg de semente) e difenoconazole + thiamethoxam aplicados sobre as cultivares de trigo TBIO Mestre, TBIO Itaipu e TBIO Sinuelo. Na inoculação foram utilizadas as bactérias do gênero Azospirillum. A semente de trigo mantém a sua qualidade fisiológica quando se verifica a germinação, vigor e o envelhecimento acelerado independente da cultivar, utilização ou não de fungicida, inseticida e A. brasilense. O inseticida thiamethoxam aumenta o comprimento da parte aérea e raiz e apresenta compatibilidade com o A. brasilense e o fungicida inibe o comprimento da parte aérea e raiz e é incompatível com a bactéria A. brasilense.UEL2018-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2616410.5433/1679-0359.2018v39n2p855Semina: Ciências Agrárias; Vol. 39 No. 2 (2018); 855-864Semina: Ciências Agrárias; v. 39 n. 2 (2018); 855-8641679-03591676-546Xreponame:Semina.
