Abstract
The agricultural production systems employ large numbers of compounds for applications in agriculture in order to increase the quantity and quality of products. Brazil has become one of the largest consumers of these compounds in the world and, although they have an important role in agricultural productivity, these compounds are present in alarming amounts in surface water bodies and groundwater. Although they have an important role in agricultural productivity through minimizing pest activity and stimulate the growth of plants, they can create serious environmental impacts. In this context, different mechanisms are being studied in order to minimize these problems, for example, the development of sustained release systems using nanoparticles, which allows an increase in performance/efficiency of bioactive compounds. Therefore, this project aims at the development of new delivery systems for herbicides, fungicides and growth hormones used globally, so as to minimize the impacts of these on the environment, increase efficiency herbicide/antifungal and increased plant growth and fruits in order to reduce degradation processes in physico-chemical environment and improve the effect on target organisms. In this context, besides the development of new formulations for sustained release of herbicide/fungicide/growth hormones, also intend to study the stability of formulations, the nanotoxicological aspects and interaction with humic substances and soils matrix in order to find formulations that minimize impacts in the environment and humans. The importance of this project lies in the dimension of market bioactive compounds used in agriculture in the Brazilian economy and the world. Thus, the area of nanotechnology has potential in research and development of new technologies producing low impact on the environment and therefore to society. (AU)
