Prevention

Preventing the entry of new weed populations is an integral component of Integrated Weed Management. Particularly for herbicide resistant weeds, entry of these new species may cause abrupt, significant, and costly changes to management programs. Therefore, prevention measures that target the potential entry of new weeds to the field are often the most cost-effective way to keep weed pressure down. Even though some weeds are spread by natural means, some primary means of weed introduction are human-caused and preventable: farm equipment, crop seed, livestock feed, and manure.

Careful monitoring of potential weed-containing products can go a long way toward preventing new weeds. Click the sections below to learn how to prevent weed introduction via equipment, seed and commodities, and livestock:
