The invention provides a biologically active composition comprising an oil, preferably a solid paraffin wax, having dispersed therein a number of inclusions which contain a toxicant, advantageously a systemic pesticide, and a dispersing agent, the average diameter of said inclusions being between 10<-><8> and 10<-><5> m, their preparation, and, when the toxicant is a pesticide, their use in combating pests. The composition may also include additives for release rate optimisation and/or improvement of mechanical strength, in the case of a solid composition. |
