Provided are preparation of ethofenprox film-spreading oil solution and application of the ethofenprox film-spreading oil solution on control of rice plant hopper. A preparation method of the ethofenprox film-spreading oil solution and the control effects of the ethofenprox film-spreading oil solution on the rice plant hopper are disclosed. The optimal formula is that the film-spreading oil solution comprises the following components, by mass: 1-20% of ethofenprox, 5-25% of solvents, 1-20% of surfactants, 1-10% of film-forming additives, and the balance soybean oil. The preparation method comprises evenly mixing the solvents and the diffusion additives which form the ethofenprox film-spreading oil solution, then adding ethofenprox raw pesticide, carrying out stirring and dissolving, and adding the surfactants, and evenly stirring to obtain the ethofenprox film-spreading oil solution. The ethofenprox film-spreading oil solution is used on the water surface, namely active ingredients can spread and diffuse on the water surface rapidly after the ethofenprox film-spreading oil solution is scattered or dripped to the water surface, and pests moving on the water surface or pests inhabiting or harming the portions of plants close to the water surface can be killed. The ethofenprox film-spreading oil solution has the advantages of rapidly spreading to form a film and being capable of effectively forming the film or spreading at the portions of the plants close to the water surface by adsorption or capillarity.

The invention discloses etofenprox emulsified powder and a manufacture method thereof, relating to an agricultural insecticide and a manufacture method thereof. The etofenprox emulsified powder is prepared from the following raw materials by weight percent: 1-50% of etofenprox, 5-30% of wetting and dispersing agent, 0-10% of solvent and the balance of carrier. The process has the steps that: (1) weighting and taking the raw materials based on the above weight percent; (2) evenly mixing the etofenprox and solvent, enabling the evenly-mixed liquid to be absorbed on carriers, then evenly mixing with the wetting and dispersing agent; and (3) crushing the mixed raw materials by a jet mill, and enabling the particle diameter thereof to satisfy the condition that 98% of particles can pass through sieve pores of 45mu m. Another manufacture method is to evenly mix the etofenprox, the solvent and the wetting and dispersing agent and lead the mixed liquid to be absorbed on the carriers. The etofenprox emulsified powder provided by the invention has the advantages of safety, environment protection, stable storage and good disinfestation effect, can be used for preventing and curing rice planthoppers, rice water weevil and Cruciferae vegetable vegetables cabbage caterpillars.
