1. Insecticidal compositions based on phosalone, characterised in that they consist of an aqueous suspension of phosalone, containing a thickener and a surface-active adjuvant wherein the surface-active adjuvant is such that : a) when 100 cc of an aqueous emulsion containing 50 g of phosalone and 5 g of the adjuvant have been agitated and then left to stand for 30 minutes at 50 degrees C, this emulsion does not give rise to the separation of an oily phase having a volume of more than 20 cc, and b) when 100 cc of an aqueous suspension containing 50 g of phosalone, in the form of solid particles having a diameter of between 1 and 10 mu and 5 g of surface-active adjuvant have been left to stand for 30 minutes at 20 degrees C, and 9/10ths of the volume has been removed, without agitation, from the upper part, the remaining 1/10th has a solids content which is less than 12% by weight of the initial solids content of the total suspension. |
