1-(1,2-DIPHENYL-ETHYL)-3-(2-HYDROXYETHYL)-THIOUREA COMPOUNDS FOR COMBATING ANIMAL PESTS

摘要

The present invention relates to a method of combating animal pests which comprises contacting the animal pest, their habit, breeding ground, food supply, plant, seed, soil, area, material or environment in which the animal pests are growing or may grow, or the materials, plants, seeds, soils, surfaces or spaces to be protected from animal at- tack or infestation, with a pesticidally effective amount of at least one 1-(1 ,2-diphenyl- ethyl)-3-(2-hydroxyethyl)-thiourea compound I or an agriculturally acceptable salt thereof, wherein m is 0 to 5, n is 0 to 5, R³ and R⁴ are H or optionally substituted alkyl, haloalkyl, cycloalkyl, phenyl or benzyl, R⁷, R⁸, R⁹ and R¹⁰ are H or optionally substituted C₁-C₆-alkyl, C₁-C₆-haloalkyl, C₁-C₆- alkylamino, C₁-C₆-alkoxy, C₃-C₆-cycloalkyl, phenyl or benzyl and the variables R¹, R², R⁵ and R⁶ are as defined in the claims. The invention relates also to a method for protecting crops from attack or infestation by animal pests, a method for protecting non-living materials from attack or infestation by animal pests, novel 1-(1 ,2-diphenyl-ethyl)-3-(2-hydroxyethyl)-thiourea compounds I and their agriculturally acceptable salts as well as to an agricultural composition comprising a 1-(1 ,2-diphenyl-ethyl)-3-(2-hydroxyethyl)-thiourea compound I or a salt thereof.
