Abstract

The development of nanopesticides has gained prominence among the applications of nanotechnology in agriculture. In particular, gains in efficiency, active ingredient protection, and targeted delivery of pesticides are the main highlights and recent discoveries in this area. Investigations of environmental behavior and regulatory issues, including effects on non-target organisms, cultures, and the environment are raised as frontiers of knowledge for nanoformulations. In addition to laboratory studies, which are already being carried out, studies that simulate the application environment to guide management decisions and environmental risk should be the focus of future research. Mesocosm studies can be intermediary environments for such investigations. In this sense, the aim of this project is to study the effects of metribuzin nanoformulation in the quality of soil and plants when applied in an agricultural ecosystem (soil-plant mesocosm experiments). In addition, the present project will promote a better understanding of the behavior of polymeric nanoparticles as herbicide carrier in the crop species, weed plants, soil community, and environmental conditions. These aspects are very important to regulatory and future uses of nanopesticides in agriculture and will help us to understand changes and particularities of the behavior of nanoformulation. (AU)
