Anredera cordifolia (Ten.) Stennis, commonly known as the madeira vine, is a succulent vine that produces vegetative structures on stems and invades agricultural areas in Brazil. This plant has become a possible invader in Brazilian agriculture with records of losses in coffee crops. The objective of this study was to study the influence of dimensional variation and different depths of planting aerial bulbils on the growth and development of A. cordifolia plants, as well as to study the influence of the effect of herbicides on postemergence control. All experiments were carried out in a greenhouse. In the propagation experiment, a completely randomized design with six replications was used. Aerial tubers of four weight categories (C) (C1, 0–0.59 g; C2, 0.60–1.49 g; C3, 1.50–2.99 g; C4, 3.0–12.0 g) were evaluated regarding the percentage of viable tubers, number of stems per tuber (ST), average stem length, shoot dry matter, and emergence speed index (ESI). ST and ESI were evaluated at seven soil depths (0, 3, 6, 10, 15, 20, and 30 cm). For experiments with herbicides, a completely randomized design with four replications was used. Six herbicides (chlorimuron-ethyl, flumioxazin, glyphosate, metsulfuron-methyl, saflufenacil, and glyphosate + saflufenacil) at the recommended doses and a control (without herbicide) were used to evaluate the postemergence control. Plants from larger tubers had a higher sprouting rate and faster growth and establishment, and tubers grown on the soil surface produced plants with faster development. Glyphosate + saflufenacil was more effective in controlling this plant species, with 79.50% control. All other herbicide treatments caused only chlorosis and poor control.
