“…Similar results were reported by Haerr et al (2016), who, when assessing the effect of fungicide application (pyraclostrobin + metconazole) on the chemical composition of maize hybrids for the production of silage in the USA, observed a linear drop in the contents of ADF with the foliar fungicide application. With two application (V5+R1), they observed a decrease of 1.13% in ADF content, and with three applications (V5+R1+R3), they still observed a decrease of 1.91% in ADF content.…”

“…NDF values of forage or silage are basically influenced by sowing density, differences between genotypes, stresses caused by the environmental conditions dependent on the sowing seasons, agricultural harvest and possibly the occurrence of diseases Mendes, Gabriel, Faria, Rossi and Possatto (2015a); Venancio et al (2009). Regarding the occurrence of diseases, Haerr et al (2016) state that foliar diseases tend to modify the chemical characteristics of the plant, due to the increase in the lignin production as a defense mechanism to prevent the entrance of pathogens inside the cells, increasing the contents of NDF and ADF of silage. Means followed by similar lowercase letters, in the same column, for the hybrids, and uppercase letters, in the same row, for the foliar fungicide application do not statistically differ from each other by Tukey's test at 5% probability.…”

“…According to Venancio, Rodrigues, Begliomini and Souza (2009), fungicide application tends to cause changes in plant physiology that may improve the nutritional value of the forage. As for Haerr et al (2016), the application of foliar fungicide linearly reduces the contents of fiber present in the forage.…”

The objective of this study was to evaluate the effect of foliar fungicide application on the chemical characteristics and in situ digestibility of forage and silage in forage maize hybrids with different grain textures in two sowing seasons. A randomized complete block design was used with four replications, in a 4 x 2 factorial arrangement, 4 hybrids, with and without foliar fungicide application, in two sowing seasons. The hybrids used were DKB240PRO, AS1572PRO, 32R48YH and AG8690PRO3. Data were tested by analysis of variance; the means were compared by Tukey’s test at 5% probability and two non-orthogonal contrasts were performed. The application of fungicide on forage maize hybrids reduced the content of neutral detergent fiber (NDF), acid detergent fiber (ADF), soft dough stage and in the silage produced. The sowing season in December negatively influenced the chemical parameters of forage maize hybrids, compared to sowing in October. Hybrids with highly vitreous endosperm presented the highest contents of NDF and ADF, soft dough stage and in the silage produced. The application of fungicide (trifloxystrobin + prothioconazole) at the V8 and R1 stages positively influenced in situ digestibility soft dough stage and in the silage produced, depending of the sowing season.

“…Pesquisas recentes demonstram que a aplicação de fungicida em lavouras destinadas a produção de silagem pode ser uma estratégia para aumentar a produção e a qualidade química do alimento e Haerr et al (2016) afirmam que alterações fisiológicas provocadas por aplicações de fungicidas tendem a aumentar a produção de matéria seca comparado à plantas que não foram infectadas com doenças, o que pode causar um aumento na digestibilidade e no conteúdo nutritivo da planta.…”

NEIVERTH, J. Características bromatológicas de trigo duplo propósito associado à aplicação foliar de fungicida. ResumoO objetivo desta pesquisa foi avaliar a eficiência de fungicidas, isolados ou em associação, e seu efeito sobre as características bromatológicas de trigo duplo propósito, cultivar BRS Umbu. O experimento foi desenvolvido no campo experimental da Universidade Estadual do Centro Oeste -UNICENTRO, campus CEDETEG, no município de Guarapuava, PR. O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 4 x 3, sendo quatro fungicidas em três fases da cultura, estes em três repetições, totalizando 36 parcelas. Os tratamentos foram: 1-testemunha (sem aplicação); 2-triazol; 3-estrobilurina e 4-triazol + estrobilurina, e as fases de aplicação dos fungicidas foram: 1-vegetativa (perfilhamento); 2-reprodutiva (florescimento) e 3-vegetativa + reprodutiva. Foi utilizada a cultivar BRS Umbu e para os tratamentos os fungicidas: triazol (ciproconazol -200 mL ha -1 ); estrobilurina (trifloxistrobina -300 mL ha -1 ); triazol + estrobilurina (ciproconazol + trifloxistrobina -200 mL ha -1 ). Foram avaliadas as características bromatológicas: nutrientes digestíveis totais (NDT), teores de fibra em detergente neutro (FDN), teores de fibra em detergente ácido (FDA) e hemicelulose (HEM). As médias foram comparadas pelo teste de Tukey, a 5% de probabilidade. A aplicação de fungicida do grupo químico do triazol reduz os teores de fibra em detergente neutro e fibra em detergente ácido, sendo estes dependentes da fase de aplicação. A aplicação de fungicida em fase reprodutiva e vegetativa + reprodutiva demonstrou efeito positivo sobre os parâmetros bromatológicos da forragem de trigo duplo propósito.Palavras chave: Triticum aestivum; forragem; qualidade de fibra; controle de doenças.
