Rate Structure - The Flexstar GT present label specifies rates of 3 pt/A to 4.5 pt/A for use in glyphosate tolerant soybean. This rate structure provides 0.2 - 0.4 lb ai fomesafen and 1 - 1.5 lb ae glyphosat. Keep in mind that these rates are dependent on where you are in Indiana. If you are South of 1-70 you can use up to 4.5 pt/A, but if you are North of I-70 you are restricted to a maximum use rate of 3.75 pt/A.
A new supplemental label allows the reduced rate of 2.375 pt/A of Flexstar GT on non-glyphosate resistant weeds. This rate provides 0.19 lb ai fomesafen (0.8 pt/A of Flexstar) and 0.78 lb ae glyphosate. The supplimental label specifically mentions morningglory, velvetleaf, and black nightshade. Applications at this rate should be made on 2-4 inch weeds.
