Herbicide Waiting Periods: What You Need to Know Before Planting Cover Crops

0:03 On the topic of being organic, on the flip side we get a lot of questions on what herbicides—well, twofold: what herbicides can I use on

0:19 This cover crop and then second if you know maybe sprayed roundup beforehand, how long do I have to wait before I can plant this? I know that's a kind of opening up a can.

0:28 of worms but what would your response be?

0:31 Dale, I'm gonna give you two minutes.

0:34 Okay, Roundup and Paraquad have no waiting period, you can plan.

0:41 Immediately.

0:43 Dale, how about liberty? Is that same?

0:45 Liberty is the same.

0:46 Yes, and a lot of people are using liberty more and more because.

0:50 It kills mare's tail very well and it kills roundup resistant pigweeds very well as long as they're small and has no residual.

1:01 It's safer to the applicator than paraquat. If you add 2,4-D or dicamba, then your waiting period can...

1:14 Be very long. I mean standard rule of thumb is basically a day per ounce of 2,4-D and 2 days per ounce of dicamba.

1:38 Mixed cover crop depends a lot on the season and the species. If you've got a particular weed issue that you're concerned about.

1:48 Just let us know and we'll see what we can come up with. It's a lot better to plan the mix around the need to use a certain size, say want to.

2:01 Control fall panicum or some grassy weed. We might be able to put together a mix that can all tolerate dual metallic. So just let us know up.

2:15 Front and we can work with you and kind of design around a mix that could all be tolerant to a certain type of herbicide. You're definitely going to give up a lot of diversity options if you want to use something with the residual. It's not impossible, but you're certainly going to be limited on what you can use.
