Timely info from UGA Extension Weed Specialist, Dr. Prostko below. Spiderwort or Bengal Dayflower is popping up in peanut fields. Post emergence control is most effective when the weed is less than 2″. When larger than 2″, Strongarm is going to be more effective than Cadre. Call if you have questions. Tucker Price 229-507-8862
Prostko – Growers who do not like Sonalan can use Prowl. Growers who do not like Dual Magnum can use one of the following: Anthem Flex, Enversa, Outlook, Warrant, Zidua. Growers who do not like Basagran can use Storm or make their own “Georgia Storm” (Ultra Blazer @ 16 oz/A + Basagran 5SL @ 6.4 oz/A). Growers who do not like Cobra can use Ultra Blazer. Growers who do not want to use Cadre are likely to see less control of sicklepod and nutsedge (sorry but that’s the truth!)
For growers who did not get their PRE herbicides applied, there is hope!
I have heard thru the grapevine that Ultra Blazer is short or non-existent in GA at this time. I have also heard that there was about 11,000 gallons of Cobra in a Valdosta warehouse last week. So growers who are told that there is no Cobra, need to think about shopping elsewhere!
Bengah Dayflower (AKA Spiderwort) in Peanuts – Prostko
I have been getting lots of questions about Benghal dayflower. It thrives in wet weather! Also, Benghal dayflower will be worse in peanut fields planted after May 15 and into June. The key to controlling this weed is moisture activated residual herbicides (Group 15’s). I have no preference but we do have more data with Dual Magnum simply because the other Group 15 herbicides (Anthem Flex, Enversa, Warrant, and Zidua) were not on the market way back then. Outlook has been around for awhile but was always the Group 15 red-headed step child for various reasons until recently (labeled for peanut in 1999)
