Embodiment 1

[0060] Example 1: Indoor combined toxicity study of dihydrosanginarine and tripterygium alkaloids on hawthorn Tetranychus

[0061] 1.1 Test materials

[0062] Test insect: Hawthorn spider mite (Tetranychus viennensis Zacher): the test insect is a female adult mite with the same size and development, collected from an apple tree in the yard of the Pollution-free Pesticide Research Service Center of Northwest A&F University;

[0063] Test agents: Dihydrosanginarine, provided by the Northwest A&F University Pollution-Free Pesticide Research Service Center, with a content of >90%; 30%.

[0064] 1.2 Determination method

[0065]The poisoning effect on the hawthorn spider mite adopts the dipping method recommended by FAO. Stick a 2.5cm wide double-sided adhesive tape horizontally on one end of the glass slide (length equal to the width of the slide). Use a No. 0 brush to pick up strong female adult mites (healthy and lively, with basically the same individual size and color), an...

Embodiment 2

[0099] Example 2: Preparation of 1.5% dihydrosanginarine·tripterygium alkaloid environment-friendly emulsifiable concentrate (1)

[0100] At 20-25°C, take 1 part of dihydrosanguinarine and 0.5 part of tripterygium alkaloids, add 20 parts of engine oil, 20 parts of diesel oil, 1 part of ten Sodium dialkylbenzene sulfonate, 6 parts of octylphenol polyoxyethylene ether, 6 parts of nonylphenol polyoxyethylene ether formaldehyde condensate and 2 parts of agricultural anion-phosphate, and then 43.5 parts of ethyl acetate as a solvent 1.5% dihydrosanginarine·tripterygium alkaloid emulsifiable concentrate can be prepared by stirring at a stirring speed of 800-1000 rpm for 10-30 minutes.

Embodiment 3

[0101] Example 3: Preparation of 1.5% dihydrosanginarine·tripterygium alkaloid environment-friendly emulsifiable concentrate (2)

[0102] At 20-25°C, take 1.5 parts of dihydrosanginarine·tripterygium alkaloids (the compounding ratio of dihydrosanginarine and tripterygium alkaloids is 2:1), and add 10 parts of organic Silicon, 78.5 parts of diesel oil, 6 parts of sodium dodecylbenzene sulfonate, 2 parts of octylphenol polyoxyethylene ether and 2 parts of styrene ethylphenol polyoxyethylene polyoxypropylene ether, at a stirring speed of 800-1000 rpm Stir for 10-30 minutes to prepare 1.5% dihydrosanginarine·tripterygium alkaloid emulsifiable concentrate.

Abstract

The invention discloses a plant source synergistic mixture acaricide comprising dihydrosanguinarine and a preparation method thereof. The preparation is emulsifiable concentrate, microemulsion or water emulsion, and the preparation is mianly used for preventing tetranychus viennensis and tetranychus cinnabarinus. The preparation comprises 0.1%-20% of the dihydrosanguinarine, 0.1%-20% of tripterygium alkaloid, and some additive. The plant source synergistic mixture acaricide does not have any chemical pesticide components, has low-toxic property for people and livestock, has performance of environment-friendly, prevents the mite disasters of fruit trees, vegetables and flowers and has great application and popularization values, so it is new non-pollution insecticide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a plant-derived synergistic compound acaricide and its preparation, specifically an acaricide with two plant-source substances, dihydrosanginarine and tripterygium alkaloids, as active ingredients and its preparation method. Background technique [0002] Plant pesticides are abundant on the earth. It is estimated that there are 10,000 species of plants on the earth, among which poisonous plant species account for about 4% of the total number of plant species. The United States has successfully developed a method for identifying the toxicity of plant extracts, and has tested 739 kinds of higher plants. The results are compiled into a table and input into the computer. Through a special program, the most effective plant extract for preventing and controlling a specific pest can be obtained at any time. Materials; 886 kinds of insecticidal plants, 150 kinds of nematodecidal plant...
