O Laboratório de Fitossanidade do Centro de Pesquisa para Agricultura Familiar (Cepaf) da Epagri presta serviço de diagnose de problemas fitossanitários para agricultores e técnicos. Nos anos de 2018 e 2019, foram encaminhadas ao laboratório 166 amostras para diagnóstico de doenças. Dentre essas amostras, aproximadamente 31% eram de soja, 21% de milho, 13% de videira, 7% de feijão, 5% de tomate e 5% de citros. Os agentes causais mais comuns eram fungos, seguidos de bactérias, detectados em 79% e 16% das amostras, respectivamente. Os diagnósticos orientam os agricultores na tomada de decisão quanto à implementação de medidas de manejo adequadas, buscando sustentabilidade ambiental, econômica e social. |

This work aimed to evaluate the following hypotheses: 1) the daily grazing time (GT) and 2) forage searching are more associated with the sward structure than with the levels of daily forage allowance (FA). To this end we proposed a model that was tested through an analysis of the sward structure, grazing time, and displacement in grazing by heifers on the natural grassland of the Pampa Biome (southern Brazil), which has been managed by FA levels since 1986. For three seasons, between January 2009 and February 2010, we evaluated the effect of FA on the main descriptors of the sward structure (herbage mass, sward height, and tussocks frequency) and the effect of these on the GT, displacement rate (DR), and daily displacement (D) in grazing. The data were analyzed with the use of regression and descriptive analyses from three-dimensional contour graphs with the data of the sward structure and GT. The DR was not associated with the FA levels or sward structure; however, the DR presented a positive linear relationship with the D and GT. The incremental change in the GT was accompanied by an increase in the D. Lastly, independently of the level of the FA and season evaluated, the lower values of GT were always associated with the following structural configuration: forage mass between 1 400 and 2 200 kg DM ha1, sward height between 9 and 13 cm, and tussock levels not exceeding 35%. Outside these limits, a penalty occurred in the GT and displacement patterns of the heifers. We found evidence that a better understanding of the cause?effect relationships between the sward structure and the ingestive behavior of the animals demonstrates the possibility of increasing the performance of domestic herbivores with important economic and ecological consequences.
