Emamectin benzoate-indoxacarb suspoemulsion and preparation method thereof

The invention relates to the technical field of pesticide preparations. The invention relates to an emamectin benzoate-indoxacarb suspoemulsion and a preparation method thereof. The suspoemulsion is prepared from the following raw materials in percentage by weight: 2-7% of emamectin benzoate, 10-20% of indoxacarb, 3-10% of a carrier, 1-3% of a surfactant, 5-10% of an organic solvent and the balance of water, wherein the carrier is a white carbon black/titanium dioxide composite material. According to the emamectin benzoate-indoxacarb suspoemulsion, the active ingredients can be adsorbed in thecarrier, the stability of the suspending agent is improved, and local agglomeration or sedimentation of the active ingredients is avoided, so that the pesticide effect of the suspending agent is improved, the maximum suspension rate of the emamectin benzoate reaches 99.90%, and the maximum suspension rate of indoxacarb reaches 99.30%. After the suspoemulsion is applied for 14 days, the preventionand treatment effect on r
