What herbicide with clearfield sunflowers?

**Aging Baby Boomer** · 03-08-2017, 02:15 PM

In your humble opinion, which herbicide works best for over-the-top weed control in sunflowers......Beyond, clethodim or Panoramic? Looking at the labels, Beyond and Panoramic seem to be the same thing.

Clethodim = grass only

Beyond is very similar to Cadre and a lot of pigweed is resistant to that class of herbicides. I believe Panoramic is a generic in that family.

Best bet is a strong pre program and hopefully you only need a shot clethodim to clean up some grass

Agree. Spartan and prowl sprayed after planting, incorporated by 1/2" of slow rain.

Nothing will hold that long and still let a sunflower grow. Either run some down and spray or hire some amigos

what would use you to spray that late?

our pigweed is certainly round up resistant. Didnt have good luck last year with cadre. not sure what is next other than gramoxone

I used cadre last year and it had zero affect on the pigweed in my field. Would like to try something different this year. Heard of some people using Ziduia, I think that it, over there flowers with good results. Just don't know if I want to take a gamble on a herbicide that might kill my flowers.

**Southernduck** · 03-09-2017, 10:23 PM

Hadn't heard that one yet but Zidua is in the same class as Dual and Warrant and both work well in sunflowers. Stuff is expensive though, same price range as Cadre.

Late sprays on pigweed, gramoxone or maybe Aim. Dicamba or 24d if it is not more than 6".

Spot spray or hood spray dicamba or gramoxone

I was referring to late sprays as after leaf drop. If you do that shit during the growing season, well the growing season just ended.

I will be spraying dual magnum and spartan charge for my preemergent and used it last year with great results. Spray within 3 days before a rain for best results.

What do you suggest spraying for pigweed if you put drops on your sprayer?

**Slaya** · 03-10-2017, 08:53 AM

Has anyone tried Warrant as a Pre-emergent? Had a friend telling me they were spraying it with good results.

Nothing really if you have ALS resistant pigweed (Cadre doesn't work). If you can put the drops really low, use low pressure and stay really straight in the furrow you could spray roundup or maybe aim but you are still gonna kill some sunflowers. a hooded sprayer would work much better.

All that said I am planting conventionals this year. With cadre being a weak herbicide and expensive, the juice isn't worth the squeeze.

Slaya I have used warrant in the past, it is good, same class as dual. might work a little better.

I have had good luck with Warrant, but, like with all of them, you have to get the right amount of rain after application.

I am torn with whether the pigweed is resistant, or if the chemical is just extremely moisture dependent. We have some great years and some terrible. Same pigweed seed bed.
