Abstract Background although efficient, there are still few options for selective treatments with herbicides applied in the pre-emergence of cotton, and treatments that result in injuries to the crop are often carried out. Objective to evaluate the influence of the amount of bean or oat straw on the selectivity of the fomesafen herbicide applied in pre-emergence of cotton. Method two experiments were carried out simultaneously in a greenhouse in a completely randomized design, with four replications. The experimental units were […]

The introduction of new cultivation technologies for soybean, corn and cotton contributed to a significant increase in the productivity of these crops. A highlight among these technological advances is the resistance of these crops to glyphosate, which initially provided for better weed control, especially in areas with a great diversity of species. Additionally, from a practical point of view it can also be highlighted that the increased time span for weed control, looking at the possibility of applying glyphosate at […]
