 Although herbicides are the most common control measure for weeds, there are other methods available.

“Depending on the circumstances, cropping systems or crop types (row crops), cultivation is still a valid way to kill weeds,” says Brook. “Biological controls are being developed and registered that can target specific problem weeds. A crop rotation with a mix of spring and fall seeded crops can also be effective in managing problem weed populations. Heavy crop plant populations, seeding early, silaging the crop and patch control are all options available for weed control. Weeds must be immature enough to be controlled by the method you choose. Once weeds have gone to seed, the damage to crop yield has been done and you end up with a bigger weed seed bank in the soil.”

Brook says it is important that weeds are dealt with as soon as possible. “There are many methods that help to reduce the effects of weeds on crop yield. Use all of them and don’t restrict yourself to using only herbicides. Most important, however, is no matter the method you choose, deal with weeds while they are small and easy to control to best preserve your crop yield.”
