New compounds which are herbicide antagonists that are useful for protection of plants from various herbicides are members of the group having the general structural formulas: <IMAGE> <IMAGE> <IMAGE> in which R is hydrogen or C1 to C4 alkyl, alkenyl or alkynyl, branched or straight chain, R1 is C1 to C3 alkyl, alkenyl or alkynyl, branched or straight chain, with the total number of carbon atoms in R and R1 being less than six, preferably less than four, on compounds with both R and R1 substituents. The novel plant protection agents may be applied both to seeds and to the soil.
