Well firstly, if you read what I wrote above about Flame in Clearfield canola, the same principle applies to Clearfield wheat. Flame is a lot cheaper than Midas and OnDuty, so if you are allowed to use it, use Flame. That makes Clearfield wheat a bit more attractive in terms of profit potential. I would not be growing any of the current Clearfield wheat varieties unless I could use Flame. I would be growing these wheats on paddocks whe...
