Summary:Industrial seed treatment is a modern agricultural practice that aims to provide protection of seeds and seedlings from pests, diseases, and pathogens in the early stages of crops. The research with wheat cultivars aims to evaluate the effects of industrial seed treatments and their influence on agronomic and morphological traits. A randomized block design was used, arranged in a factorial scheme (10 * 2 * 2), with 10 treatments Imidacloprid; Thiodicarb; Imidacloprid + Thiodicarb; Pyraclostrobin (Thiophanate-methyl + Fipronil); Fluxapyroxad; Fluxapyroxad + Imidacloprid; Fluxapyroxad + Thiodicarb; Fluxapyroxad + Imidacloprid + Thiodicarb; Fluxapyroxad + Pyraclostrobin (Thiophanate-methyl + Fipronil); control (without anyproduct application), two cultivars (TBIO Sossego and ORS 1401), two sowing dates (June and July) and four replicates. The following variables were evaluated: plant stand, number of tillers, hectoliter weight, 1000-grain weight, and grain yield. The means of the variables were subjected to individual variance analysis and grouped by the Scott-Knott test at p [less than or equal to] 0.05. Additionally, 15 non-orthogonal contrasts were performed. The neonicotinoid active ingredient in the industrial treatment increased the number of tillers, 1000-grain weight, and grain yield. The carboxamide fungicide, alone or in combination, positively affected the plant stand. Treatment with fungicides or insecticides increases the grain yield of the evaluated cultivars. The agronomic and morphological traits were influenced by the sowing dates, with the second date showing the bestgrain yield. The TBIO Sossego cultivar showed higher values for plant stand, thousand-grain weight, and grain yield than ORS 1401 under the field conditions evaluated. Key words: Triticum aestivum L., fungicide, insecticides, stand, grain yield O tratamento industrial de sementes e uma pratica agricola moderna que visa fornecer protecao de sementes e mudas contra pragas, doencas e patogenos nos estagios iniciais das culturas. A pesquisa com cultivares de trigo visa avaliar os efeitos dos tratamentos industriais de sementes e sua influencia em caracteristicas agronomicas e morfologicas. Foi utilizado o delineamento em blocos casualizados, arranjados em esquema fatorial (10 * 2 * 2), com 10 tratamentos Imidacloprido; Tiodicarbe; Imidacloprido + Tiodicarbe; Piraclostrobina (Tiofanato-metil + Fipronil); Fluxapiroxade; Fluxapiroxade + Imidacloprido; Fluxapiroxade + Tiodicarbe; Fluxapiroxade + Imidacloprido + Tiodicarbe; Fluxapiroxade + Piraclostrobina (Tiofanato-metil + Fipronil); controle (sem aplicacao de produto), duas cultivares (TBIO Sossego e ORS 1401), duas epocas de semeadura (junho e julho) e quatro repeticoes. Foram avaliadas as seguintes variaveis: estande de plantas, niimero de perfilhos, peso hectolitro, massa de 1000 graos e produtividade de graos. As medias das variaveis foram submetidas a analise de variancia individual e agrupadas pelo teste de Scott-Knott com p [less than or equal to] 0,05. Adicionalmente, foram realizados 15 contrastes nao ortogonais. O ingrediente ativo neonicotinoide no tratamento industrial aumentou o niimero de perfilhos, a massa de 1000 graos e a produtividade de graos. O fungicida carboxamida, sozinho ou em combinacao, afetou positivamente o estande de plantas. 0 tratamento com fungicidas ou inseticidas aumenta a produtividade de graos das cultivares avaliadas. As caracteristicas agronomicas e morfologicas foram influenciadas pelas epocas de semeadura, sendo a segunda epoca a que apresentou melhor produtividade de graos. A cultivar TBIO Sossego apresentou maiores valores de estande de plantas, massa de mil graos e produtividade de graos do que a ORS 1401 nas condicoes de campo avaliadas.
