Abstract

Difluoromethoxyphenyl thiophosphates of the formula I ##STR1## where R¹ is alkyl of not more than 3 carbon atoms, R² is unsubstituted or substituted alkyl of not more than 5 carbon atoms, Y is hydrogen or chlorine, X is oxygen or sulfur and R³, R⁴ and R⁵ are each hydrogen, halogen, nitrile, alkoxy or alkylthio, each of not more than 4 carbon atoms, or unsubstituted or substituted alkyl of not more than 4 carbon atoms, their preparation and their use as agents for controlling pests, in particular insects and other arthropods.

Claims

1. A difluoromethoxyphenyl thiophosphate of the formula ##STR112## where R¹ is alkyl of not more than 3 carbon atoms, R² is unsubstituted alkyl of not more than 5 carbon atoms or said alkyl substituted by methoxy, ethoxy, isopropoxy, ethylthio or chlorine, Y is hydrogen or chlorine, X is oxygen or sulfur and R³, R⁴ and R⁵ are each hydrogen or halogen.

2. A method of protecting crops from insects and other arthropods which comprises:

applying to said crops a composition containing a carrier and an effective amount of a compound as defined in claim 1.

3. A compound of the formula I as defined in claim 1, wherein R¹ is ethyl.

4. A compound of the formula I as defined in claim 1, wherein R² is propyl, butyl, ethoxyethyl or ethoxypropyl.

5. A compound of the formula I as defined in claim 1, wherein R¹ is ethyl and R² is propyl, isobutyl, sec.butyl, ethoxyethyl or 2-ethoxypropyl.

6. A method of protecting crops from insects and other arthropods which comprises:

applying to said crops a composition containing a carrier and an effective amount of a compound as defined in claim 5.

7. A composition for protecting crops against insects and other arthropods which comprises:

a carrier and an effective amount of a compound as defined in claim 1.
