Canola label change notice

The labels on haloxyfop products used for post-emergent grass control in canola crops are to be amended to overcome concerns that the ‘Directions for Use’ have the potential to be misinterpreted.

In particular there is concern that the directions with respect to the correct application window and appropriate withholding period have not been clear enough to ensure users fully comply with domestic and international residue limits.

To clarify the situation, following discussions with registrants, it has been proposed that haloxyfop labels be amended to more clearly define the timing of use in relation to the crop growth stage. The aim is to avoid mistimings that might result in unwanted residues.

Consequently, it has been proposed that haloxyfop product labels are to be changed to read as follows:

Apply from two-leaf to eight-leaf stage of crop growth. DO NOT apply after the commencement of stem elongation. This means that application must not occur after the eight-leaf stage or if stem elongation commences before the eight-leaf stage application must not occur after stem elongation has commenced.

Application later in the crop cycle – after stem elongation – can result in the crop retaining haloxyfop residues in the canola seed and seed products. This could breach standards established both in Australia and overseas and jeopardise trade.

The new label makes this clear and should assist in both crop management and in avoiding potentially damaging residue issues.

Successful grass control can be critical for canola growers to achieve maximum return for effort, with a significant proportion of post-emergent grass control in canola crops being undertaken with herbicides containing the active ingredient haloxyfop, for example, Verdict 520®, Asset® or Inquest® and others.
