Imox residual

[SD51555]

If a guy sprays Imox in late May, can he still expect winter cereals to grow planted mid august without suffering any loss to residual herbicide? Thinking the 2 oz/ac rate to try to save my chicory.

And is there a non-legume annual you can plant right after Imox to use up summer nitrogen from the clovers?

The strict and literal read of any label for any of the herbicides in the family of imidazolinones would indicate the answer to your first question is no and to the second, none. But if you can live on the edges you could probably do fall planted wheat after a spring application of Imox. The published half-life of the herbicide ranges from 14 days to nearly 200. It depends on soil caracteristics, pH, soil organic matter, seasonal rainfall. Is wheat doable? I would have a hard time betting the farm in production ag, but for habitat? Depends on your risk tolerance. To your second question, when you say “right after” I take it to mean days after the herbicide application and I would say I don’t know. It seems doubtful.

I was afraid of that. I'll probably still go for it, just knowing I may not get a winter cereal crop. I can always come back and try forage barley in the following spring at at heavy rate. And if that still doesn't work, there's always japanese millet in June.

If it doesn't work, I'm out maybe $35 in winter trit. I'm not gonna chance not-succeeding for $35. That seed is getting planted.
