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.
新的除草化学物质的化学式为:##STR1## 其中X为三氟甲基;Y为氢、卤素、硝基和氰基中的一种,R为硝基、烷基硫、卤素和氰基中的一种;包括其除草剂组合物和控制杂草的方法。该化合物,3-四氢呋喃基2-硝基-5-(2-氯-4-三氟甲基苯氧基)苯甲酸酯,特别适用于控制杂草——大花蓟,并对玉米和大豆安全。大花蓟生长在玉米和大豆作物中,其存在会降低这些作物的产量。
