Abstract
A pyrazoline having the formula: ##STR1## wherein: R.sup.1 and R.sup.2 are selected independently from a group consisting of hydrogen with the proviso that only one of R.sup.1 and R.sup.2 can be hydrogen, substituted or unsubstituted alkyl of from 1-20 carbon atoms and substituted or unsubstituted aryl of 6 to 20 carbons, or R.sup.1 and R.sup.2 can together comprise the atoms necessary to complete a heterocyclic group of 5 to 6 nuclear carbon and hetero atoms; PA1 R.sup.3 and R.sup.4 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 to 6 nuclear carbon and hetero atoms, or R.sup.3 and R.sup.4 together are an alkylene group of 4 to 5 carbon atoms. R.sup.5 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 to 6 nuclear carbon atoms. Compounds of the above formula are useful as aphicides and fungicides.
