Abstract: Background: The species Bidens pilosa, Euphorbia heterophylla, and Amaranthus hybridus have shown high interference in soybean cultivation, especially due to biotypes resistant to various herbicides. Objective: This study aimed to analyze the effectiveness of soil cover associated with pre-emergence herbicides in managing these species Methods: Separate experiments were conducted for each weed species in a completely randomized design with a 4 × 4 factorial scheme and three replications. The evaluated factors were chemical management (diclosulam, flumioxazin, sulfentrazone, and an […]
