New thiophosphoric acid esters of the formula ##STR1## and their manufacture are disclosed; in this formula R.sub.1 is methyl, yl, n-propyl or isopropyl and R.sub.2 is n-propyl or isopropyl. Such compounds are suitable as active ingredients for combating nematodes.

Nematocidal unsubstituted phenyl esters of

The present invention relates to new dithiocarbamic acid esters having the formula ##STR1## wherein R.sub.1 represents a phenyloxyphenyl or phenylaminophenyl radical which is unsubstituted or substituted by lower alkyl, halogen, trifluoromethyl, nitro or cyano, R.sub.2 represents hydrogen or lower alkyl, and alk represents lower alkylidene or lower alkylene, and also to salts of compounds of the formula (I), wherein R.sub.2 represents hydrogen, with pharmaceutically acceptable bases. These new compounds possess a strong anthelminthic activity and are useful for the treatment of warm-blooded animals infected with parasitic helminths. A specific embodiment is the N-[4-(4-nitroanilino)-phenyl]-dithiocarbamic acid-(2-carboxyethyl)-ester.

Dithiocarbamic acid esters

Organic phosphoric acid derivatives of the formula ##STR1## wherein R.sub.1 is C.sub.3 - C.sub.5 alkyl, optionally interrupted by oxygen or sulphur,

Insecticidal and acaricidal substituted phenyl thiophosphoric acid esters

Thiophosphoric acid amides of the formula ##EQU1## wherein R represents the n-propyl or n-butyl radical, and A represents the ethylene, 1-methylethylene, 1,1-dimethylethylene, 2-butenylene or 2-pentenylene radical are very effective agents for combating nematodes, insects and members of the order acarina.

Thiophosphoric acid amides as nematocides, insecticides and acaricides

Methanesulphonic acid-2-bromoethyl ester has been found to possess nematocidal properties. It may be used in the form of suitable compositions.

Methanesulfonic acid-2-bromoethyl ester nematocide

Insecticidal and acaricidal compositions and methods for combating insects and acaricides are provided wherein the active insecticidal ingredients are phosphoric acid phenylsulphonamide esters of the formula ##SPC1## Wherein Y represents oxygen or sulphur, R represents alkyl with 1 to 5 carbon atoms, R.sub.1 represents alkyl with 1 to 5 carbon atoms, alkenyl and alkinyl each with 3 to 5 carbon atoms, alkoxyalkyl with 1 to 5 carbon atoms in each of the moieties, alkylthioalkyl with 1 to 5 carbon atoms in each of the moieties, or haloalkyl with 1 to 5 carbon atoms, R.sub.2 represents hydrogen, alkyl with 1 to 5 carbon atoms or alkenyl with 3 to 5 carbon atoms, R.sub.3 represents hydrogen and X and X.sub.1 each represents halogen or alkyl with 1 to 5 carbon atoms, or R.sub.3 represents alkyl with 1 to 5 carbon atoms and X and X.sub.1 each represents hydrogen, halogen or alkyl with 1 to 5 carbon atoms.
