The integrated utilization of the various weed management options should focus on the most economical and effective control of noxious weeds. Anything that weakens the weed, prevents spreading, or prevents seed production can be a valuable tool. The options or tools that are integrated into an effective weed management plan may be biological, cultural, or chemical. However it may take a few years for the insect population to multiply to a sufficient level for effective weed control. Therefore the perimeter of infestations should be chemically controlled to prevent the spread of the weed while the insects are multiplying.
Pathogens are disease causing organisms including fungi, bacteria, viruses, etc.
This area of weed control warrants more exploration. Grazing animals are being used successfully to help suppress weed growth and seed development. Replanting also helps reduce soil erosion. Grazing management is a valuable tool for controlling weed establishment and growth. Overgrazing will favor the growth of weeds while taller grasses shade the soil and provide competition against weeds.
