摘要

Pesticidal compositions comprise an organic compound of tetravalent tin of the formula FORM:0835546/VI/1 in which at least one of R1-R4 represent one of the following radicals: (i) diethyl-dithio carbaminato- (ii) -ethylene-bis-dithiocarbaminato- (iii) -pentachlorophenolato- (iv) -2 : 4 : 6-trichloro phenoxy-aceto- (v) -mercapto-benzthiazolato- (vi) -(trichloromethyl-mercapto-dicarbethoxy)- methyl- (vii) -para-toluene-sulphamido and the other radicals represent alkyl groups in the form of an aqueous emulsion or dispersion or in powder form in admixture with a solid carrier. Specified compounds are di-n-butyl - bis - (diethyl - dithiocarbaminato) stannane, ethylene - bis - dithiocarbaminatobis - (triphenyl) stannane, tri - n - butyl - mono-pentachlorophenolate stannane, tri-n-butyl-(2 : 4 : 6 - trichlorophenoxyaceto) stannane, di - n-propyl - di - mercaptobenzthiazolato stannane, tri - n - butyl - (trichloromethyl - mercapto - dicarbethoxy) - methyl stannane, tri - n - butyl-(para-toluene-sulphamido) stannane.
