ABSTRACT:
The invention provides broad spectrum fungicidal diacylimide compositions which include compounds having the formula: ##STR1## where R and R' are selected from alkyl, alkenyl, haloalkyl and haloalkenyl having from 1-5 carbon atoms, being the same or different groups.
The compositions of this invention show excellent agricultural fungicidal activity, particularly against bean rust, rice spot, tomato blight and other agricultural pathogens.
The diacylimide compounds generally are prepared by reacting a suitable amide with an acyl halide. The acyl halide precursor may be prepared, if necessary, from the corresponding acid by reaction with a suitable halogenating agent, such as thionyl chloride. Similarly, a given amide may be readily prepared, for example, from the corresponding acyl halide by reaction with ammonia.
