Claims
- 1. A process for protecting crop plants from attack by mites, which comprises treating the crop plants with an effective amount of at least one compound of the formula ##STR21## in which at least two of X.sub.1, X.sub.2, X.sub.3 and X.sub.4 are fluorine and any of X.sub.1, X.sub.2, X.sub.3 and X.sub.4 which is not fluorine, is chlorine, and A is a group ##STR22## wherein R.sub.1 is hydrogen or a halogen atom,
- Z is CH or a nitrogen atom,
- n is 0 or 1, and
- R is alkyl having 1 to 6 carbon atoms or a halogen atom;
- or A is a group ##STR23## in which Z, n and R have the above-stated meanings.
- 2. The method of claim 1 wherein the compound of Formula I is N-(2,2-difluoro-1,1,2-trichloroethylthio)-N-phenyl methane sulfonamide having the formula ##STR24##
- 3. The method of claim 1 wherein the substituent A in Formula I is the group ##STR25## wherein R.sub.1, Z, n and R are as defined in claim 1.
- 4. The method of claim 3 wherein Z is CH.
- 5. The method of claim 3 wherein R.sub.1 is chlorine.
- 6. The method of claim 1 wherein two of the substituents X.sub.1, X.sub.2, X.sub.3 and X.sub.4 in formula I are fluorine and the other two are chlorine.
- 7. The method of claim 1 wherein the compound of Formula I is N-(1,2,2-trifluoro-1,2-dichloroethylthio)-N-phenyl methane sulfonamide.
- 8. The method of claim 1 wherein the compound of Formula I is N-(2,2-difluoro-1,1,2-trichloroethylthio)-N-(4-chlorophenyl) methane sulfonamide.
- 9. The method of claim 1 wherein the compound of Formula I is N-(2,2-difluoro-1,1,2-trichloroethylthio)-N-(3-chlorophenyl) methane sulfonamide.
- 10. The method of claim 1 wherein the compound of Formula I is N-(2,2-difluoro-1,1,2-trichloroethylthio)-N-(3-pyridyl) methane sulfonamide.
- 11. The method of claim 1 wherein the compound of Formula I is N-(2,2-difluoro-1,1,2-trichloroethylthio)-N-phenyl chloromethane sulfonamide.
- 12. The method of claim 1 wherein the compound of Formula I is N-(2,2-difluoro-1,1,2-trichloroethylthio)-N-(2-methyl phenyl) chloromethane sulfonamide.
