Weed control options: Mulches are one of the better options, but they don't control perennial weeds

摘要

There are no easy solutions to controlling weeds in an organic orchard or vineyard. While there are several options available for organic growers, most have pros and cons to their use, says a University of California weed ecologist. Effective and economical weed control is one of most often cited problems by organic growers. The more common organic weed control methods include cultivation, mulch, flamers or burners, biological control, and organic herbicides. Some work well on annual weeds, but not perennials, said Dr. Tom Lanini, weed ecologist at UC-Davis, who shared his thoughts on weed control options during a telephone interview.
