<p>Certain haloalkylcarbonylamino-1,3-dioxane herbicide antidotes corresponding to the following general formula: <CHEM> wherein R represents chloro-, bromo- or iodo- C1-C4 alkyl; R1 represents hydrogen, C1-C4 alkyl, C2-C4 alkenyl or phenyl; R2 represents hydrogen or C1-C4 alkyl; R3 represents hydrogen or C1-C4 alkyl; and R4 represents hydrogen or nitrophenyl; provided that one of R3 and R4 represents hydrogen; are disclosed, as is the production thereof. Such compounds may be formulated with inert diluents or carriers and or adjuvants or with herbicides, in particular thiocarbamates or acetanilides. The use of such compounds counteracts crop damage caused by herbicides and hence provides a method of establishing herbicidal selectivity.</p> |
