Weed Control Questions Peanut Notes No. 52 2019

— Written By

Question:

A grower missed a field of peanuts at preemergence with Valor and Warrant and Gramoxone. What do you think would be the best combination to use right now? .They were planted about 9 days ago and they are just starting to emerge. He doesn’t mind burning them. I was thinking maybe 1 pt of Gramoxone and his Warrant. They are pretty weedy and grassy but not horrible.

Answer:

Go with 11 oz Gramoxone plus 0.5 pint of Basagran plus any of the residuals (Dual Magnum, Warrant, Outlook or Zidua). If grass is big you might have to come back with clethodim. Just be ready to do something else in about 10-14 days as a follow up.

Question:

Is Liberty a good burndown option for marestail.

Answer:

Yes, it is a good option for this weed. Try to control it as well as possible before the peanuts come up. Options in peanuts are very limited and only marginally effective.
