Haloxyfop warning for canola growers
9 August 2018
Agriculture Victoria is urging canola growers to limit their use of herbicides containing haloxyfop to before the 8 leaf growth stage or commencement of stem elongation.
Post emergent grass control is important for growers and herbicides that contain the active constituent haloxyfop are commonly used for this purpose. In 2016 labels for haloxyfop products were changed to provide clear instructions to users on when to apply the chemical.
Labels now state;
- ‘DO NOT apply after the 8 leaf stage of the crop’
- ‘DO NOT apply after the commencement of stem elongation’
In Victoria prohibitive label statements such as ‘DO NOT’ statements are legally enforceable under Agricultural and Veterinary Chemicals (Control of Use) Act 1992.
“Based on residue testing conducted by the National Residue Survey (NRS) there have been detections of haloxyfop residues above the relevant Maximum Residue Limit (MRL) for canola, which is of concern,” Statewide Chemicals Specialist Steven Field said.
Agriculture Victoria is informed of any residues detected above MRLs by the NRS and investigations are conducted to determine the cause of the residues.
“This includes a thorough audit of a grower’s agricultural chemical use, so using a chemical in strict accordance with the label is always the best way to manage the risk of unacceptable residues,” Mr Field said.
“Growers are also reminded that they should treat on-farm stored grain with registered chemicals in accordance with the labels. The correct declaration of on-farm treatments at the point of delivery are required to be made.
“All farmers should have an appreciation of the importance of maintaining our clean and green image with our export markets.
“The use of agricultural chemicals that results in residues exceeding MRLs - domestically or internationally - can severely jeopardise market access for all growers. People that misuse chemicals put at risk not only their own livelihood but that of their family, friends and local community.”
Agriculture Victoria is working closely with grain handlers and other industry bodies to address this issue and will provide more information once current investigations have concluded.
