Productivity and forage quality of elephantgrass (Pennisetum purpureum) are directly affected by weed interference. The difficulty of control of these species is one of the main barriers to production and use of the forage as feedstock, as well as to the production of biomass for energy use. Despite the great progress in agro-ecological weed control techniques, herbicides are still indispensable. Thus, the rational use practices of these products should be improved in order to produce quality fo

Concern about the environmental impacts of agricultural activities has taken on a large dimension, especially in the last decade. These impacts are expressed, for example, in reduction of biological diversity, erosion and contamination of soils, silting and contamination of water springs, increase of agrochemical residues in food, among others. However, the incorporation of the concept of sustainability has led agricultural research in the growing search for alternative and sustainable models of

Pastures of Cynodon spp. and elephantgrass ( Pennisetum purpureum Schum.) have their productivity and forage quality directly affected by weed interference. The difficulty of controlling weeds is one of the main obstacles to growing and using these forage crops as an input in animal feeding, as well as in the production of elephantgrass biomass for energy use. Despite the progress in agroecological weed control techniques, herbicides are still indispensable, especially in crops on ...
