The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Planting date influences critical period of weed control in sweet corn (2006, background): “Determining the appropriate timing of weed control tactics is valuable in developing integrated weed managements systems (Knezevic et al. 2002; Rajcan and Swanton 2001) and has been the subject of extensive research in agronomic crops (Zimdahl 2004).”
Late-Season Seed Production in Arable Weed Communities: Management Implications (2012, background): “Late-season weed escapes are prevalent in several crop production systems (e.g., Leeson et al. 2005), but they exert limited influence on crop yield (Zimdahl 2004).”
Plant biodiversity enhances bees and other insect pollinators in agroecosystems. A review (2012, unknown): “Naturally, careful manipulation strategies need to be defined in order to avoid weed competition with crops and interference with certain cultural practices (Zimdahl 1980).”

Weed seedbank and community shifts in a long-term cropping systems experiment (2005, background): “The negative relationship between crop yield and weed biomass is well known (Zimdahl 2004), but the effect of weed community diversity on crop yield is not well characterized.”
