Keys to successful weed management is sustained effort, reevaluation and the adoption of improved strategies. County weed supervisors and private consultants can assist you with IWM strategies. Preventing rangeland weed introduction is the most practical and cost-effective management method. Prevention should include limiting weed seed dispersal, minimizing soil disturbance and properly managing desirable vegetation. Weeds encroach in small infestations, which generally are spread from a large infestation.
Eradication usually is achievable on a small scale.
The program includes noting infestation boundaries on site and on maps, determining proper control procedures and the number and timing of follow-up applications. This generally requires aggressive annual applications of herbicides. Revegetation of infested areas may be required to eradicate weeds in areas without desirable species that can re-occupy the site after weeds are controlled. Eradication of small patches requires continual monitoring to ensure permanent removal of the weed. Most successful large-scale weed control programs are completed in steps.
