New herbicidal chemical compounds of the formula: ##STR1## wherein X is trifluoromethyl; Y is selected from the group consisting of hydrogen, halogen, nitro and cyano and R is selected from the group consisting of nitro, alkylthio, halogen and cyano; herbicidal compositions thereof and methods of controlling weeds therewith. The compound, 3-tetrahydrofuryl 2-nitro-5-(2-chloro-4-trifluoromethylphenoxy) benzoate, is particularly useful for the control of the weed, velvetleaf, and safe to corn and soybean. Velvetleaf is found in corn and soybean crops and its presence will lower the yield of these crops.
