| ABSTRACT This study was conducted to evaluate the efficacy of joyweed (Alternanthera tenella) control and antagonistic or synergistic potentials of saflufenacil herbicide applied alone or tank mixed with paraquat, metribuzin and clomazone. The experiment was conducted in a greenhouse in a completely randomized design with four replications. Treatments consisted of saflufenacil herbicide doses (0, 0.4, 0.7, 1.4, 2.1 and 2.8 g ha-1) applied isolated or associated with paraquat (0, 1 and 3 g ha-1), metribuzin (0, 38.4 and 105.6 g ha-1) or clomazone (0, 288 and 504 g ha-1). Visual control was determined at 14 and 21 days after spraying the herbicides (DAA) and shoots dry matter at 21 DAA. Colby's method was used to calculate the response from herbicide... |

| ABSTRACT Tolerance, also referred to as natural resistance, is a feature that exists in the plant even before herbicide application in an area. I. grandifolia, I. indivisa and I. purpurea are among the tolerant species most commonly found over fields in southern Brazil. We hypothesized that the intensive use of glyphosate results in increasing levels of tolerance to glyphosate, and in pronounced response variability in populations of the same Ipomoea species. This study aimed at identifying tolerance variations to glyphosate among I. grandifolia, I.indivisa and I. purpurea morning glory species and among populations of these species. In crops over Paraná and Santa Catarina states (Brazil) 31 biotypes were collected (20I. grandifolia, 7I.indivisa and 4I.... |
