Materials and methods
- Principles of method if other than guideline:
- The influence of some environmental variables on the herbicidal activity of acrolein on submerged foliage of Potamogeton pectinatus and on the dissipation of acrolein in the CORFO irrigation channels was investigated. For the dissipation studies, data were collected from 146 acrolein treatments acrolein application as herbicide for weed control) in irrigation channels during three sucessive years under different conditions. The downstream concentration of acrolein was measured as a function of time at several sites along the first 5 km from the application point.

Results and discussion
Any other information on results incl. tables
The constant rate of dissipation K was determined to be 0.235 L/h implying that the chemical will disappear in <24 h. The dissipation average per kilometer was 1.607 mg/L. This indicates that within <10 kilometres, all acrolein will be dissipated. The results showed a high correlation with water flow and the acrolein concentration, accounting for 68% of the herbicidal losses from the water system. Velocity of the water, conductivity, pH and duration of treatment had a lesser effect on the dissipation while the volume of the product applied, temperature, turbidity and level of weed infestation were unimportant.
