Weed Control Question

Question or Comment

You must be psychic. Well, I reckon you did have a clue. Yes Valor was the question. We accumulated enough info to steer away from Valor.

I have now had a chance to scout. All I see at cracking is pMG, MG and SP. (given your powers I assume you can interpret my shorthand) Generally with SP as a major player I like to go early with Gramoxone and follow with Cadre to take us home. Comments?

I see that ET is labeled. I have not tried it. I would envision it a late season cleanup of pMG as needed. I didn’t see it in the efficacy ratings. Would it give us anything on SP and how much peanut burn do we get?

Answer or Ramble: 

Not psychic just know many fields of peanuts were planted through last Thursday that did not get sprayed, and with the volume of rain, it was going to be difficult to be within the appropriate window of application of Valor SX (within 3 days of planting.) Application of paraquat, Basagran and more residual (metolachlor products, Outlook, and maybe Strongarm in some cases) would be a good approach. This program will handle a lot of small weeds including sicklepod, moringglories, grasses and pigweeds. ET would be great on morningglory but would not kill the sicklepod, grasses or pigweeds (with any size). The followup with Cadre is a good approach, especially if sicklepod is in the field. I suspect if Palmer amaranth is present some portion of the population is ALS resistant, so applying Cobra or Ultra Blazer at some point with Cadre might help clean up the field. Naturally it would be good to wait and see what is present and escapes the paraquat program.

ET is effective on morningglory but limited in most other cases. Paraquat is much broader when applied to small weeds. Hope this helps.

Peanut tolerance to ET is okay but it is just very narrow in what it offers.
