Under a chemically based weed control strategy, problem weeds may develop chemical resistance, requiring more chemicals of higher toxicity.
As the above is intended to illustrate, in weed management, the assumption is often that it is the weed that is having the financial impact rather than the context in which the weed issue arises and is then managed.

Four Corners reveals the full extent of the problems caused by the chemicals.
It is now widely accepted by experts that dioxin is the common factor that causes health problems in people who were exposed to herbicides.
Four Corners has found evidence that herbicides containing 24D, currently being sold, do have levels of dioxin which could pose a potential health risk.
To add to the problem posed by the lack of regulation enforcement, there is also evidence that farmers are spraying forms of 24D that drift across large tracts of neighbouring land creating a potential danger to other farm crops.
