A non-rheopectic aqueous concentrate of a pesticide comprising: (a) at least one symmetrical bis-carbamoyl sulfide compound of the general formula:
wherein: R is: Rz
R3 wherein:
R2 is alkyl, alkylthio, alkoxy, alkanoyl or alkoxycarbonyl, all of which may be unsubstituted or aliphatically-substituted in any combination with one or more cyano, nitro, alkylthio, alkylsulfinyl, alkylsulfonyl, alkoxy or R4R5-NCO-groups; or R2 is phenyl, R4RsNCO- or R6CON(R4); wherein
R4 and R5 are individually hydrogen or alkyl;
R6 is hydrogen, alkyl or alkoxy;
R3 is hydrogen, alkyl, alkylthio or cyano;
A is a four-or five-member divalent aliphatic chain which includes one or two divalent oxygen, sulfur, sulfenyl or sulfonyl groups and which may include not more than one divalent amino, alkylamino or carbonyl groups, in any combination; provided that the total number of carbon atoms in R may not exceed eight and provided further than when R2 is alkyl substituted with alkylthio, R3 is cyano alkyl or alkylthio; and wherein R' is alkyl containing from one to four carbon atoms; the said bis-carbamoyl compound being present in an amount of from about 35 to 50 weight percent, (b) a dispersant, in an amount of from about 0.5 to about 5 weight percent, (c) a thickener, in an amount of from about 0.02 to about 0.5 weight percent, and (d) a wetting agent, in an amount of from about 0.0 to 1 weight percent, the said weight percents being based on the total weight of the concentrate.
