Onions is a challenging crop in which to achieve good weed control. They are planted in high density configurations that preclude the effective use of cultivation. Cultural practices such as locating plantings in fields have low weed populations, as well as preirrigating up a flush of weeds followed by killing them with shallow cultivation can be effective in minimizing the population of weeds that emerge during the crop cycle. In general, excellent weed control for many of the common cool and warm season vegetables can be accomplished by a combination of the registered pre and post emergence herbicides. The weed control challenges in onions occurs with weeds that are not well controlled by currently registered herbicides. It is...

You just KNOW that some plants are considered weeds. Their common names give them away. They sound awful. Giant hogweed (Heracleum mantegazzianum). Ripgut brome (Bromus diandrus). Devil's claw (Proboscidea lutea). Smellmelon (Cucumis melo). Itchgrass (Rottboellia cochinchinensis). Dog-strangling vine (Cyanthum rossicum).
Others...well, others seem more benign. Even sweet. For Valentine's day I present to you nine weedy plants with lovely names. Enjoy...
