Grain growers have been warned to examine their crop rotations this year to ensure this year's cropping program is not constrained by herbicide residues. Last year's short, dry season has the potential to make some of this year's crops vulnerable to herbicide carryover. Dr Terry Piper said some chemicals might not have broken down sufficiently, which might cause problems for this year's crops. Any paddock where these products were applied in June or later last season should be regarded as having potentially damaging levels of residues, as should areas where they were applied even earlier in the season where it has been dry. Cereals grown after triazine tolerant canola are most at risk.
