Title: Parasiticidal compositions
IPC: A01N47/14
Filed: 1959-10-08
Abstract: A parasiticidal, fungicidal, nematocidal or bactericidal composition comprises a salt of a dithiocarbamate having the general formula <FORM:0929203/VI/1> in which X is oxygen or sulphur, R is an aliphatic group having not more than nine carbon atoms, the chain of which may be interrupted by an oxygen atom and which may contain halogen or nitro substituents, R1 is an alkylene group containing two to six carbon atoms, M is a metal, a primary or secondary amine or an ammonium or substituted ammonium group, and n is the valency of M, together with a liquid diluent, a finely divided solid diluent or a surface-active agent.  When M is a metal it may be an alkali metal, such as sodium potassium or lithium, an alkaline earth metal, such as calcium, barium, strontium or magnesium, or a heavy metal, such as zinc, cadmium, copper, lead, mercury, iron, cobalt, nickel, chromium or manganese.  When M is a substituted ammonium group it may be a trialkylammonium group, such as trimethylammonium, methyldiethylammonium or triethylammonium or a trialkylolammonium group such as tri-ethanolammonium.  The group R may be an alkyl group such as methyl, ethyl, isopropyl, tertiary butyl, n-heptyl, 2-ethylhexyl or n-nonyl, or halogen or nitro-substituted alkyl group, such as chloromethyl, 2-chloroethyl, 2,3-dichloropropyl, 2-bromoethyl, 2-iodoethyl, 3-fluoropropyl, 2-nitroethyl or 4-nitrobutyl; it may also be an alkenyl group such as allyl, butenyl or octenyl, or a halogen or nitro-substituted alkenyl group such as 2-chloroallyl, 2,3-dichloroallyl, 4-bromobutenyl, 3-nitroallyl or 4-nitrobutenyl; R may also be an alkynyl group such as propargyl, 3-butynyl or 2-heptynyl or a halogen or nitro-substituted alkynyl group such as 2-chloropropargyl, 3-bromopropargyl or 4-chloromethylpropargyl.  R may also be an alkoxyalkyl group such as methoxyethyl, ethoxypropyl, ethoxymethyl, propoxypropyl, ethoxyamyl, methoxy-2-ethylhexyl, ethoxyheptyl, vinyloxyethyl, isopropenoxyethyl, allyloxyethyl or 2-butenyloxybutyl. Specified active ingredients are sodium N-methoxyethyl-dithiocarbamate, potassium N-ethoxypropyldithiocarbamate, barium N-butoxypropyldithiocarbamate, zinc N-ethoxypropyldithiocarbamate, cupric N-methoxyethyldithiocarbamate, ammonium N-methoxyethyldithiocarbamate, ammonium N-methylthioethyldithiocarbamate, triethanolammonium N-methoxyethyldithiocarbamate, triethylammonium N-methoxyethyldithiocarbamate, methyldiethylammonium N-methylthiopropyldithiocarbamate, sodium N-methoxyhexyldithiocarbamate, sodium N-2-ethylhexoxyethyldithiocarbamate, sodium N-n-nonoxyethyldithiocarbamate, manganous N-methoxyethylthioethyldithiocarbamate, sodium N-propoxypropyloxypropyldithiocarbamate, sodium N-ethoxymethylthioethyldithiocarbamate, potassium N-isopropoxy-n-hexylthioethyldithiocarbamate, sodium N-2,2-dimethyl - 3 - butyloxyethyldithiocarbamate, sodium N-isoamylthiopropyldithiocarbamate, sodium N-isobutyloxyethyldithiocarbamate, sodium N - n - butylthiopropyldithiocarbamate, sodium N - ethylthio - n - amyldithiocarbamate, sodium N-allylthioethylpropyldithiocarbamate, ammonium N - allyloxyethyldithiocarbamate, ammonium N-2-butenyloxyethyldithiocarbamate, ammonium N - propargyloxypropyldithiocarbamate, sodium N - 2 - chloroallyloxyethyldithiocarbamate, sodium N - 3 - bromoethyldithiocarbamate, cadmium N-3-chloropropargylthioethyldithiocarbamate and nickel N-methylthioethyldithiocarbamate.  The composition may be used in the forms of solutions or dispersions in water or organic solvents with or without surface-active agents or as solid formulations, e.g. wettable powders and dust, or emulsifiable concentrates.
