Treatments - Integrative Pest Management

Physical Strategies

  • Tillage - enables the farmer to attack many weed survival mechanisms, preventing seed production in annual plants and destroying the underground parts of perennial plants.
  • Hand Weeding - destroys annual, biennial, and non-creeping perennials.
  • Mowing - cutting as close to the ground as possible can destroy weeds in areas where cultivation or hand weeding are impractical or impossible.
  • Grazing - repeated removal of top growth prevents seed formation and gradually weakens underground parts, if grazing is properly managed.
Cultural Strategies
  • Crop Rotations - certain groups of weeds are associated with specific crop rotations and changing the crops can reduce or eliminate repeat, persistent weeds associated with those specific crops.
  • Plant Competition - one of the cheapest and most useful general weed control available to all farmers.  "Survival of the fittest."
  • Crop Establishment - generally the first plants to germinate and emerge in an area tend to exclude all others, so work toward a vigorous dense crop.
Biological Strategies
  • Use of natural agents such as insects, nematodes, fungi, viruses or fish for the control of weeds.
  • In some instances, grazing animals can be used to harvest and stress noxious weeds.
Chemical Strategies
  • The success of 2,4-D when introduced commercially in 1946 launched the present era of herbicides.  It is important to understand the basics of herbicides to determine the most effective treatment.
  • Read and understand all chemical labels when using.
