| Resumo: |
Corn (Zea mays) is the main cereal grown, demanding more and more technologies and manufacturing to increase productivity and profitability. The frequent use of herbicides to control weeds, which can be cultivated with the same nature, is a biodiversity of the soil, which can lead to the degradation of the same. The effects that are not possible to the determination of the applications of post-emergent herbicides made in the culture of the organics of the fauna of epiedáfica. The experiment was conducted in the experimental area of the Federal Technological University of Paraná, Câmpus Dois Vizinhos, in the period of February 2018. The experiment was evaluated by a completely randomized design, with 3 plots divided into 4 blocks of 40 m 2, in which was cultivated corn and the fauna epiedografia evaluated by the trap trap method, with 3 traps per block, as were collected weekly, during 5 weeks. The results were constituted by three herbicides, the post-emergence measures in the maize crop and a control treatment. Eleven taxonomic groups were identified, varying their density as a function of the time period and the week studied, being the Hymenoptera group more representative throughout the study. It was not able to do a large number of treatments every week. The effect of the herbicides to the length of weeks mean significance, such as total organic density of edfcientential in theeffects of the fat extents of the week of weeks. |
