07/12/07 Consider Imi-wheat following Pursuit use in pulses

Farm and Ranch July 12, 2007 It is yet to be seen if yields are impacted, but AgriPro wheat breeder John Moffatt says he has seen some fields the last two years where Pursuit had been used on peas, lentils, or chickpeas, and where the herbicide residual negatively impacted the subsequent wheat crop. Moffatt says growers might want to consider planting an imadazolinone resistant, or Clearfield wheat, in those circumstances. Moffatt: "This year I think the yield lag in those varieties that didn't have imi-resistance is going to be significant. It is just a visual estimation right now and kind of a gut feeling, but boy the symptoms were dramatic. And the setback was dramatic. I mean it put non-imi wheats into kind of suspended animation for two or three weeks before they decided to start growing again and the imi wheats were just clicking along like nothing happened. So, something significant is happening there. We will have to wait and see if it comes out in the combine but I tell you it wasn't very pretty. Wasn't very pretty. So I think it is something guys should consider as an option when they are thinking about some of their pea, lentil ground. Maybe they ought to think about something where they don't have to worry about that kind of interaction." AgriPro does have a Clearfield wheat coming, AP700.
