Diphenylether phosphates as pesticides - from hydroxy diphenyl ethers and substd. phosphoric acid chlorides

摘要

Diphenylether phosphates of formula (I): (where R1= 1-7C alkyl, R2 = Me or Et, R3 to R11 = H or Hal, X and Y = O or S), are used to control various animal and plant pests esp. all stages of insect life, representatives of the acarina class and plant parasitic nematodes. They also have fungicidal props, and can be used against phytopathogenic fungi in e.g. cereals, vegetables, fruit trees and also to treat seed grain, fruits, tubers etc. to protect them from fungal infection. (I) may be used alone or in conventional prepns., contg. 0.1-95% of (I) and suitable carriers and/or other additional substances, (including other pesticides). (I) are prepd. from hydroxy diphenyl ethers and substd. phosphoric acid chlorides.
