摘要

The compsns. comprise a mixt. of components chosen from 10 different types of cpds. including (a) R1R2R3RSn (where R is e.g. OH; O-P(S)-S-CH(i-Pr)2 or -O-Sn(CH2C Me2Ph)3; and R1.R2 and R3 are cyclohexyl or CH2CMe2Ph) (b)Xn-C6H4-N=CHNR1R or its hydrochloride (where X is halo, alkyl, haloalkyl, alkoxyalkyl or trihalomethyl; n is 1-3; R is H or 1-4C alkyl, alkenyl or alkynyl; R1 is 1-4C alkyl -S(O)-alkyl or CH2YR2 (where Y is O or S and R2 is e.g. 1-4C alkyl); (c) a cpd. (III) (where X and Y are Cl and Z is Cl or X and Y are H and Z is Cl or Br); (d) CH2-SO2C(CH3)2-CH=N-O-CONHCH3 etc. The compsns. are used in treatment of Tetranychidae, Eryophidae, Tarsonemidae etc. on fruit trees, vines, ornamental trees, shrubs etc.
