The invention belongs to the technical field of traditional Chinese medicines, and discloses a traditional Chinese medicine composition for treating acne and an external gel thereof. The traditional Chinese medicine composition is prepared from rheum officinale, cortex phellodendri and radix angelicae according to a specific ratio, specifically, 4 parts of rheum officinale, 1 part of cortex phellodendri and 1 part of radix angelicae (F1) are used for staphylococcus aureus, and 3 parts of rheum officinale, 12 parts of cortex phellodendri and 8 parts of radix angelicae (F2) are used for propionibacterium acnes; the external gel is prepared by taking carbomer 940 as a matrix, adding glycerol, propylene glycol, triethanolamine, Tween-80, potassium sorbate and the like as auxiliary materials and adding the traditional Chinese medicine extract. The composition can be used for treating acne and improving skin inflammation and hyperpigmentation, the gel is convenient to use and stable in property, skin irritation can be reduced, medication safety and patient compliance can be improved, and meanwhile the anti-inflammatory and antibacterial effects are enhanced.

The present application relates to the field of pesticide composition, especially to a stable and efficient pyrethrum insecticide composition and its preparation method. The composition comprises at least 1-10wt% of pyrethrum, 1-25wt% of the second active substance, 5-25wt% of functional adjuvant and the rest of solvent. The composition provided in the present application is different from the existing water dispersible granules, emulsifiable concentrate and suspension concentrate of pyrethrum and acetamiprid combination, which is a soluble concentrate composition with extremely high active ingredient content. The composition has obvious advantages in drug efficacy compared with solid preparations, and is more environmentally friendly than the existing emulsifiable concentrate type, and has excellent market prospect in the field of pesticides.

The invention discloses an insecticide composition based on fenoxycarb application. The insecticide composition is formed by compounding fenoxycarb, a biological source synergistic component and an agriculturally acceptable auxiliary agent, the biological source synergistic component comprises at least one of pyrethroids, neonicotinoids, bisamides or insect growth regulators; the mass ratio of the fenoxycarb to the biological source synergistic component is (1-20): (20-1). Compared with the prior art, the pesticide composition based on fenoxycarb application has the advantages that fenoxycarb and a specific type of biological source synergistic component are scientifically compounded, the limitation of a single component is overcome, and the control effect on various agricultural pests is remarkably improved.

The application discloses an environmentally-friendly insect-repelling microcapsule, an environmentally-friendly insect-repelling asphalt additive and a preparation method thereof. The shell material of the environmentally-friendly insect-repelling microcapsule is a composite shell material comprising silicon dioxide / nano-electric jade, and the core material comprises one or more of a pyrethrum compound, a carboxylic acid ester compound, an amide compound and a plant extract; the shell material is loaded with a metal chelate on the surface. The environmentally-friendly insect-repelling microcapsule can not only efficiently and durably repel insects around roads, but also effectively inhibit the amount of pollutants generated by high-temperature action of asphalt in the production, construction and pavement process, thereby providing a new idea for functional utilization of asphalt materials.
