The present invention provides a compound preparation for preventing and controlling aquatic animal parasites, the compound preparation comprises a) at least one synthetic chemical insecticide and b) at least two plant essential oils; wherein, a mixing method of at least two plant essential oils The steps are as follows: adding the plant essential oil to liquid n-butane at ‑4 to ‑0.5 ℃ and stirring thoroughly, then adding tert-butanol peroxy, and stirring thoroughly; passing the obtained product into ultrasonic waves at ‑4 to ‑1 ℃, and Adjust the power of the ultrasonic wave until the solution is half-boiling, keep it for 0.5-1 hour, stop the ultrasonic wave and add n-butane at -4°C and keep this temperature for 0.1-0.5 hours; repeat the previous steps 2-3 times; Filter, stand, and extract to obtain mixed plant essential oils. The compound preparation of the invention is non-toxic, does not pollute the environment, is not easy to produce resistance, and has the ability to destroy the structure of cell membranes or destroy intracellular Ca 2+ Balance, achieve the effect of eliminating harmful microorganisms and parasites.

The invention relates to an insecticidal composite containing pleocidin. Effective components such as Imicyafos and pleocidin are mixed, the weight-part ratio of the two effective components is (1-40):(0.1-20), the preferred weight-part ratio of the two effective components is (5-25):(0.1-5); the total weight-part content of the effective components in the insecticidal composite is 1%-80%, the preferred weight-part content is 5%-30%, and the other components are auxiliary components which are allowed for use and can be accepted in pesticide; the known method is used for preparing wettable powder, a suspending agent, microemulsion, water emulsion and water dispersible granule. The insecticidal composite is wide in function field, high in insecticidal efficiency, less in use amount, high in control effect, less in residue, long in lasting period and beneficial to environmental protection.

The invention relates to an insecticidal composition containing chlorantraniliprole. The active ingredients are formed by mixing Imicyafos and chlorantraniliprole, wherein the ratio of weight parts of the two active ingredients is (1-50):(1-50), preferentially (5-25):(3-30); the content of total weight parts of the active ingredients in the insecticidal composition is 1-80 percent, preferentially 5-40 percent; the insecticidal composition comprises the balance of auxiliary components allowed to be used and can be accepted in pesticides. The insecticidal composition can be prepared into wettable powder, suspending agents, microemulsion, emulsion in water and water dispersible granules according to a known method. The composition has the advantages of wide application fields, high insecticidal efficiency, small amount, high control efficiency, little residues and long lasting period and contributes to environmental protection.

The invention discloses a controlled release fertilizer with a natural insecticide efficacy. The controlled release fertilizer takes chemical fertilizer as controlled release fertilizer core, and the controlled release fertilizer core is wrapped by coating material into micro capsules, the micro capsules are wrapped by natural plant decomposed materials and processed into granular controlled release fertilizer with the natural insecticide efficacy and the particle size of 1-4.75 mm or 3.35-5.60 mm after being dried; the natural plant decomposed materials comprise powder material after being crushed, decomposed and dried, wherein the powder material is tea seed residue after oil squeezing and / or tobacco waste after cigarette processing, and the amount of the natural plant decomposed material in weight percentage is 5-68.9%; according to the controlled release fertilizer with the natural insecticide efficacy, the active ingredients in the fertilizer are continuously and slowly released to the environment; and the purposes of fertilization and insecticide are realized through one-time application, the fertilizer not only has the property of controlled release, but also has insecticide material with natural efficacy, and the problem of resistance of chemical pesticide cannot be caused easily. The controlled release fertilizer is nontoxic for human and livestock and has no residue. Finally, the plant source waste can additionally provide organic nitrogen and potassium fertilizer for crops, waste is trolley converted into useful things, and the pollution to the environment is greatly reduced.

The invention relates to an insecticidal combination containing pymetrozine. Imicyafos and the pymetrozine which serve as effective components are mixed; the weight ratio of the two effective components is (1-50):(55-1), and preferably the weight ratio is (5-25):(35-5). The insecticidal combination comprises 1-80 percent of the effective components by weight, preferably 5-40 percent of the effective components, and the balance being pesticidally available and acceptable auxiliary components.
