The species Urochloa decumbens is an important weed of agricultural crops due to the high adaptive capacity and difficulty of management. The presence of these plants into agricultural production areas can cause serious problems when it competes for water, light and nutrients, besides acting as host of pests and common pathogens to the crop and interfering in harvesting. The study aimed to evaluate doses of control of U. decumbens plants by glyphosate application. Three experiments were conducted, in greenhouse in […]

The research goal was to evaluate the effects of silicone surfactant and simulated rainfall in glyphosate efficiency in controlling Brachiaria decumbens. The experiments were carried out at (a unit of the University of São Paulo) Escola Superior de Agricultura Luiz de Queiroz (ESALQ – Luiz de Queiroz College of Agriculture) in greenhouse conditions, in a randomized block design with four replications. In one experiment, a simulated rainfall of 10 mm was carried out, 30 minutes after treatments application, and in […]
