Peanut Weed Management

  Effective weed management is essential for profitable peanut production. Peanuts are not very competitive with weeds and thus require higher levels of weed control than most other agronomic crops to avoid yield losses. Weeds may also decrease digging efficiency, so effective late-season weed...

Are You Weeding Frequently Enough to Prevent Weeds From Spreading?

  Many of the most common weeds of container nurseries flower and produce seeds within 30 days. Our research suggests that you should be removing emerged weeds every 2 to 3 weeks. This prevents rapid population growth and spread, and can reduce hand weeding labor labor costs by around 40%. For...
