Manejo de herbicidas no consórcio de capins com culturas anuais

Abstract

With the various problems that have occurred in different sectors of production systems, it is necessary a rapid adaptation of Brazilian agriculture with new practices, mainly in regions with a tropical climate. So, annual intercropping systems with grasses have become a viable, profitable and sustainable alternative of production, with medium and long term benefits for the producer, promoting versatility and greater forage production for soil protection. Nevertheless, more studies are necessary for a better implantation and management of the crops to be used. In this aspect, the use of herbicides in these systems are an important alternative for the control of weeds that can compete and drastically reduce the productive. However, there is a difference in the forms of use and in the products used for each crop, although maize crop is quite flexible regarding the use of herbicides due to the large number of tolerant and resistant varieties to them, this does not apply to sorghum and millet that have higher sensitivity to the vast majority of herbicides, considerably reducing the chemical management alternatives of weeds, thus requiring different forms of management and cultural treatment.
