Agricultural chemical residues in prairie sloughs / G. Shaw and A. Gunn.

By: Contributor(s): Material type: TextTextPublication details: AB : 1979.Description: 21 p. : maps ; 28 cmOnline resources: Abstract: Phenoxy herbicides, primarily 2,4-D and MCPA, have been the major agricultural pest control chemicals in the prairies for several years (Daciw 1972, '73- '77 NRCC, 1978). According to this latter review Drift and runoff can introduce detectable quantities of herbicides into non-target aquatic ecosystems adjacent to the application site. Studies on the long-term impact of phenoxy herbicide residues have generally not been carried out under conditions relevant to those found in many of the colder parts of Canada.
