Unsymmetrical O-alkyl S'-butyl S-alkylthioalkyl dithiophosphates and oxidized derivatives thereof
Dithiophosphates of the general formula: ##STR1## wherein R' is methyl or ethyl; R" is primary or secondary C.sub.3 -C.sub.4 alkyl; Q is a C.sub.1 -C.sub.4 alkylene; y is 0-2; R.sub.1 is C.sub.1 -C.sub.4 alkyl and aryl are novel compounds having excellent pesticidal properties against insects, mites and nematodes. O-Ethyl S'-n-propyl S-alkylthioalkyl dithiophosphates in which each alkyl group has from 1 to 3 carbon atoms, are especially outstanding as pesticides of reduced mammalian toxicity and are useful in the control of the highly pesticide resistant insects of the Order of Lepidoptera.
