Listed below is some information obtained from Dr. Prostko (UGA Weed Scientist) on Cadre (imazapic) carryover and oats.\u00a0<\/strong><\/p>\n

Cadre is used on a large percentage of peanut acres in Georgia.<\/p>\n

“The official labeled rotation restriction for oats after an application of Cadre is 18 months!”<\/span><\/u><\/b><\/p>\n

” Field research conducted in Georgia indicated that the rotation for oats could potentially be reduced to 4 months<\/u><\/i><\/b>\u00a0(like other small grains<\/i><\/strong>) but the label was never changed (and will not be changed<\/strong><\/em>) due to the limited amount of oat acres planted.\u00a0 Oats were planted on 70,000 acres in Georgia in 2019. U.S. total planted oat acres were 2,810,000 in 2019.”<\/p>\n

“Oats planted less than 4 months after a Cadre application could very likely be injured (Figure 1)<\/strong>.\u00a0 Note that Cadre injury to oats also looks very much like phosphorus deficiency and\/or cold injury so these potential problems would need to be investigated as well.\u00a0 There has been at least 1 freeze event in Tifton around November 13.”<\/p>\n

“When Cadre was applied to bare-ground (a worse case scenario, i.e. 100% of Cadre reaching the soil surface and no peanut uptake\/metabolism<\/i>) either 5, 4, 3, 2, or 1 month(s) before oat planting, total forage yield was only significantly reduced by the 1 and 2 month timings (61.6% and 22.4% forage yield losses, respectively).\u00a0 Interestingly, oat grain yields were not reduced by any pre-plant application of Cadre.”<\/p>\n

“I do not have any hard data to back this statement up but it makes sense that oat injury could be worse in short-planted fields where Cadre-treated dryland<\/u><\/i><\/b> peanuts were grown.\u00a0 ”<\/p>\n
