Embodiment 1
[0009] The active ingredients are as follows by weight ratio: 10 parts by mass of nicotine, 1 part by mass of picroderm, 10 parts by mass of emulsifier (2201), 2 parts by mass of synergist (azone), 77 parts by mass of solvent (xylene) . First add most of the solvent to the preparation tank, and then add nicotine, picroderm, emulsifier, synergist and the rest of the solvent in sequence according to the conventional usage amount while stirring. Then add 0.2-0.3 parts by mass of 60-80 mesh diatomite (filter aid) and filter to obtain the synergist insecticide.
Embodiment 2
[0011] Wherein the active ingredients are by weight: 20 parts by mass of nicotine, 0.6 parts by mass of picroderm, 10 parts by mass of emulsifier (2201), 2 parts by mass of synergist (azone), 67.4 parts by mass of solvent (xylene) . First add most of the solvents to the preparation tank, then add nicotine, picroderm, emulsifier, synergist and the remaining solvent in sequence according to the conventional usage amount under stirring, then add 0.2- The insecticide is obtained by filtering 0.3 parts by mass of 60-80 mesh diatomite (filter aid).
Embodiment 3
[0013] The active ingredients are as follows by weight: 30 parts by mass of nicotine, 0.2 parts by mass of picrodine, 10 parts by mass of emulsifier (2201), 2 parts by mass of synergist (azone), 57.8 parts by mass of solvent (xylene) . First add most of the solvent into the preparation tank, and then add the nicotine, picroderine, emulsifier, synergist and the remaining solvent in sequence according to the above-mentioned amount under the condition of stirring. Finally, 0.2-0.3 parts by mass of 60-80 mesh diatomite (filter aid) is added for filtration to obtain the insecticide.
