| ABSTRACT Biological control as part of integrated weed management represents an emerging and promising method to minimize the use and impact of herbicides on the environment. The objective of this research was to determine the ecological, phytosanitary, and agronomic status of weeds associated with crops in Antioquia, Colombia, and their potential to be chosen as candidates for biological control studies using pathogenic fungi. The research was carried out through a sampling of weeds in 35 agricultural farms, distributed in 11 municipalities and 10 different crops, on which population ecological variables such as frequency and dominance were evaluated; phytosanitary variables such as incidence and severity of foliar fungal symptoms; as well as some... |

| ABSTRACT E. indica is one of the most problematic weeds in the world because it is present in almost every continent, and there are reports of multiple resistance to herbicides by some biotypes. The objective of this paper was to analyze the growth, the development and the production of this plant's seeds, in order to generate information about its biology that can be useful for management. The experiment was carried out in a greenhouse from May to September 2015. Sixteen samples were taken during the development cycle of the plant: 3, 10, 17, 24, 31, 38, 45, 52, 59, 66, 73, 80, 87, 94, 101 and 108 days after emergence (DAE). The response variables were based on a leaf area and dry matter of each one of the parts of the plant and the number of seeds... |
