The invention provides a non-polluted pesticide with pure traditional Chinese medicinal components. The pesticide is prepared from the following raw materials: raw radix stemonae, radix sophorae flavescentis, asparagus fern, smoked plum and asarum, wherein the raw materials are dried materials. The non-polluted pesticide with pure traditional Chinese medicinal components is prepared from human available traditional Chinese medicinal herbs serving as raw materials, is simple in components, good in compatible action, simple in preparation method, does not have toxic or harmful effect, pollution or residues on crops, does not pollute the environment, and has the advantages of high efficiency, quick response, long drug effect duration and wide pesticide range; effective components of the non-polluted pesticide have a killing effect to insect pests, are not toxic to human bodies, and have the effect of preventing diseases for crops; components in soil can kill insect pests in the soil, and can be used as fertility of crop growth. By adopting the non-polluted pesticide, the insect pests killed by the pesticide cannot cause secondary hazard to natural enemies of the insect pests, and components flowing into water cannot pollute the water source or poison aquatic lives, so that the natural environment and ecological balance can be facilitated. The invention also provides a method for preparing the pesticide and a method applied to crops.

The invention discloses an insecticidal composition containing flupyradifurone and bensultap. The composition includes active ingredients, namely flupyradifurone and bensultap, wherein the mass ratio of flupyradifurone to bensultap is1:(1-60). The insecticidal composition has the synergistic effect on the basis of maintaining the original control effect, expands the insecticidal spectrum and meanwhile delays the generation of resistance of pests to the pesticide. The price of flupirfurone is much higher than that of bensultap, bensultap is made to be compounded with a small amount of flupyradifurone, the insecticidal effect of the insecticidal composition containing flupyradifurone and bensultap is much higher than that of single use of flupirfurone or bensultap, the production cost is also reduced and the economic burden of farmers is relieved.

The invention provides application of fluorescence arborization nanometer macromolecule in preparing a drug carrier, application of the fluorescence arborization nanometer macromolecule in preparing a compound drug and the compound drug made of the drug carrier and a hydrophobic drug in a mixing mode, and further provides application of the compound drug in pest control. Pests are fed with the compound drug in a feeding or injecting mode, the arborization compound can serve as the drug carrier to package the drug to enter the cells of the pests quickly, the drug can play a role in the pests, the pesticide effect is enhanced, and non-target pests are effectively killed. The new strategy that the fluorescence arborization nanometer macromolecule serves as the pesticide carrier to be applied in the field of pest control is achieved successfully. The pesticide effect of the pesticide is enhanced through the application, the pest killing range is enlarged, and a new approach for avoiding overusing of chemical pesticide is provided. The fluorescence arborization nanometer macromolecule has very high application value in the fields of agricultural pest control and biology scientific research.
