Compound acaricide for greening plants and preparation method of compound acaricide

Abstract

The invention relates to the technical field of acaricide compounding and discloses a compound acaricide for greening plants and a preparation method of the compound acaricide. The acaricide is mainly prepared from active ingredients as follows: aconite, radix salviae miltiorrhizae, artemisia argyi, flos lonicerae, rhizoma chuanxiong, bauhinia variegate, radix stellerae chamaejasmes, photinia serratifolia, rhizoma dryopteridis crassirhizomatis, an organic solvent, a penetrant, a lubricant and and water. The preparation method of the compound acaricide comprises main steps of cleaning, decoction, concentration and the like. Compared with a traditional compound acaricide, the acaricide has the following characteristics: 1, common green plant Chinese herbal medicines are taken as main raw materials and are not prone to accumulating on plants and are safe and friendly to the ecological environment; 2, the preparation method is simple and feasible, low in cost and suitable for large-scale popularization in urban greening projects; 3, the raw materials are unique in mixing action mechanism and can play a synergistic efficiency to improve the control rate of pest mites, in particular to tetranychus cinnabarinus, tetranychus urticae, tetranychus viennensis zacher and other common pest mites of green plants.

Description

technical field [0001] The invention relates to the technical field of acaricide compounding, and discloses a compound acaricide for greening plants and a preparation method thereof. Background technique [0002] In recent years, with people's gradual and clear understanding of a series of environmental, ecological and human health problems brought about by chemical pesticides, the development of low-toxic, high-efficiency biopesticides that are safe for the environment and non-target organisms has become an urgent need. Among them, finding substances with insecticidal and antibacterial activities from plants has become an important way to create new acaricides. In addition, Chinese herbal medicines in various parts of the country today are idle or have limited uses, or have not been used correctly, which has brought adverse effects on human beings. market application prospects. [0003] At present, the development of new botanical pesticides is generally based on the rati...

Problems solved by technology

For example, Chinese patent CN 201410090210.4 is a compound pesticide synergist and its application in pesticide preparations. The castor oil polyoxyethylene ether, alkylphenol polyoxyethylene ether, sorbitan fat mentioned in the composition of the invention Ester is still compounded with chemical substances. Although the synergistic effect is increased to a certain extent and the dosage is reduced, the chemical substances are easy to accumulate on green plants, thereby causing pollution to the ecological environment. In urban park scenic spots, it may even cause harm to tourists. Therefore, the existing compounding technology needs to be further improved, and compound pesticides that are more friendly to humans and the environment should be used.

[0004] To sum up, for the above problems of urban greening pests and the use of chemical acaricides, people have realized that it has become a trend to develop a safe and non-residue plant Chinese herbal compound acaricide, and there will be a broad market. Market development prospects, but due to various reasons such as benefits and control effects, compound acaricides containing plant Chinese herbal medicines are not ideal in the process of promotion and use
