Late-Season Florida Beggarweed in Peanut (Prostko)<\/a><\/h3>\n\n\n\n

I have been getting a few calls\/texts\/e-mails about late-emerging Florida beggarweed in peanut fields, especially in fields that did not get a PRE application of Valor.<\/p>\n\n\n\n

Peanut growers have 2 options for the control of Florida beggarweed at this time of year.  The first is a POST application of Classic 25DG @ 0.5 oz\/A + NIS @ 0.25% v\/v.  Classic can be applied POST in peanut from 60 days after emergence (DAE) until 45 days before harvest.  The latest update that I have in regards to variety tolerance to Classic is as follows:  Classic should NOT<\/u><\/em><\/strong> be used on GA-06G<\/strong> and Tifguard<\/strong> due to potential yield losses (7-11%).  The following peanut varieties have demonstrated adequate tolerance to Classic in UGA replicated\/weed-free field trials: Florida-07; GA-Greener; GA-07W; GA-18RU; AUNPL-17; TIFNV High O\/L; GA-20VHO; and FloRun\u2122 331<\/strong>. For GA-09B<\/strong>, peanut yields were reduced by 5% when applied 75 DAE but no yield loss occurred when applied 60, 90, or 105 DAE.  For GA-16HO<\/strong>, peanut yields were reduced by 13% when Classic was applied at 70 DAE, but no yield loss occurred when applied at 60 DAE or 85 DAE.  For GA-12Y<\/strong>, peanut yields were reduced 8% when Classic was applied 60 DAE but not at 70 DAE or 85 DAE.  For TifNV-HG<\/strong>, Classic had no effect on peanut yield when applied 64 DAE or 74 DAE (only 1 year of data but repeating in 2026<\/em>). <\/p>\n\n\n\n

The second option that peanut growers have for later emerging Florida beggarweed in peanut is to use a 33% solution of Gramoxone 3SL (paraquat) in a non-selective applicator (NSA). Based upon field trials conducted many moons ago in Georgia, the following NSA’s were more effective:<\/p>\n\n\n\n
