- 3. The composition of claim 2, wherein in said compound, R.sub.1 represents 3-methyl-4-methylthiophenyl; and R.sub.4 and R.sub.5 represent methyl or ethyl.
- 4. The composition of claim 3, wherein said compound is N,N-diethyl-N'-[ O-(3-methyl-4-methylthiophenyl)-ethylthionophosphonyl]-formamidine.
- 5. The composition of claim 2, wherein said compound is N,N-diethyl-N'-[ O-(4-methylthiophenyl)-ethyl-thionophosphonyl]-formamidine.
- 6. A method for combatting insects, acaricides and nematodes which comprises applying to the loci thereof an insecticidally, acaricidally and nematocidally effective amount of a compound of the formula ##EQU6## wherein R.sub.1 represents phenyl, or phenyl mono- to trisubstituted by halogen, mono- or disubstituted by C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkylthio, nitro, cyano or trifluoromethyl, or monosubstituted by C.sub.1 -C.sub.4 -carbalkoxy,
- R.sub.2 represents methyl, methoxy, ethyl, ethoxy or phenyl,
- R.sub.3 represents hydrogen or methyl,
- R.sub.4 and R.sub.5 represent methyl, ethyl, n-propyl, isopropyl or allyl,
- X and Y represent oxygen or sulphur, or
- R.sub.4 and R.sub.5 with the nitrogen atom to which they are bound form the morpholino, piperidino or pyrrolidino ring, or
- R.sub.3 with R.sub.4 or R.sub.5 form a pyrrolidino or piperidino ring, whereby then the group R.sub.4 or R.sub.5 not participating in the ring formation represents methyl or ethyl.
- 7. The method of claim 6, wherein in said compound, R.sub.1 represents 3-methyl-4-methylthiophenyl, 4-nitrophenyl, 3-methyl-4-nitrophenyl, 2,5-dichloro-4-bromophenyl, 2,5-dichloro-4-iodophenyl, 4-methylphenyl, 2,4-dibromo-5-chlorophenyl, 2,4,5-trichlorophenyl, 3-chlorophenyl, 3-trifluoromethylphenyl, 4-methylthiophenyl, 4-chlorophenyl or 4-cyanophenyl; R.sub.2 represents methyl, methoxy, ethyl or ethoxy; R.sub.3 represents hydrogen; R.sub.4 and R.sub.5 represent methyl or ethyl, or R.sub.4 and R.sub.5 together with the nitrogen atom to which they are bound form the morpholino, piperidino or pyrrolidino ring; X represents sulphur; and Y represents oxygen.
- 8. The method of claim 7, wherein in said compound, R.sub.1 represents 3-methyl-4-methylthiophenyl; and R.sub.4 and R.sub.5 represent methyl or ethyl.
- 9. The method of claim 8, wherein said compound is N,N-diethyl-N'-[ O-(3-methyl-4-methylthiophenyl)-ethyl-thionophosphonyl]-formamidine.
- 10. The method of claim 7, wherein said compound is N,N-diethyl-N'-[ O(4-methylthiophenyl)-ethyl-thionophosphonyl]-formamidine.
- 11. The method of claim 6 for combatting phyto-pathogenic nematodes.
