A pyrazoline having the formula:
wherein:
R1 and R² are selected independently from a group consisting of hydrogen, substituted or unsubstituted alkyl of from 1-20 carbon atoms, and unsubstituted aryl of 6 to 20 carbons, or R¹ and R² can together comprise the atoms necessary to complete a heterocyclic group of 5 to 6 nuclear carbon and hetero atoms;
R³ and R⁴ are selected independently from a group consisting of hydrogen, substituted or unsubstituted alkyl of from 1-20 carbon atoms, substituted or unsubstituted aryl of 6-20 carbon atoms, alkoxy, alkylthio, cycloalkyl or heterocyclyl of 5 or 6 nuclear carbon and hetero atoms, or R³ and R⁴ together are an alkylene group of 4 to 5 carbon atoms.
R⁵ is selected from a group consisting of substituted or unsubstituted alkyl of 1-10 carbon atoms, alkenyl of 1-10 carbon atoms, substituted or unsubstituted aryl of 6-20 carbon atoms and cycloalkyl of 5 or 6 nuclear carbon atoms.
Compounds of the above formula are useful as aphicides and fungicides.
