the boys across the water may have issues too ,taken from another forum
CTL can be detected on grain down to quite low levels as our wheat is tested for it and the contract we grow it under doesn't allow us to use CTL in our fungicide program. That said that only shows whether it is present or not, not the date it was applied. The test costs quite a lot of money as well I believe so I doubt they are going to start testing wheat in every grainstore this harvest. I would imagine the only problem that might arise is if you still have cans of CTL in the chem store when the Red Tractor inspector comes round.
