Arrowhead Spraying Program
At a meeting of the Pesticides Review Committee on 4 September, approval was given to a proposal by the Commission to spray arrowhead in the Broken and Nine Mile Creeks with 2,4,-D during 1981-82. Although not stated in the resolution, I am confident it was intended that approval be subject to agreement between the Commission and Environment Protection Authority on a water sampling program to detect any residues of 2,4-D.
*** recently informed me that spraying has started but plans for analysing water samples, or in other ways estimating residue levels, are not complete. The Commission could therefore be criticized on the grounds that it is spraying in an unacceptable way. However, it is pointed out that this program has been undertaken each year since the late sixties and was approved by the Pesticides Review Committee on a number of occasions during the early part of this period.
If spraying is to continue, it is my view that agreement should be reached immediately between the Commission and Environment Protection Authority on a program for measuring herbicide residues in water; otherwise the spraying should be suspended until such a time as agreement is reached.
