Embodiment 1

[0059] Example 1: Indoor joint toxicity study on Tetranychus cinnabarinus complexed with Chuanxiong oil and wintergreen oil

[0060] 1.1 Test materials

[0061] Test insects: Tetranychus cinnabarinus ( Tetranychus cinnabarinus Boisduval), Northwest Agriculture and Forestry University, Greenhouse Farming of Pollution-free Pesticide Research Service Center.

[0062] Test agents: Ligusticum chuanxiong oil, provided by Guangxi Hengxin Perfume Company, with a ligustilide content of >35%; wintergreen oil, provided by Guangxi Hengxin Perfume Company, with a methyl salicylate content of >90%.

[0063] 1.2 Determination method

[0064] Indoor bioassay of mite infestation was carried out by dipping slide method. Cut the double-sided tape into two centimeters long and paste it on one end of the microscope slide, and then tear off the paper on the glue. Select a healthy adult mite, pick it up with a small brush, stick its back on the glue, and pay attention not to stick the mit...

Abstract

The invention discloses a plant source synergistic complex acaricide. The prepared plant source synergistic complex acaricide is formed by compounding cnidium oil and wintergreen oil serving as principle components and adding auxiliary agents, wherein the form of the preparation is of missible oil, microemulsion or aqueous emulsion and is mainly used for preventing and controlling tetranychus viennensis, tetranychus cinnabarinus, petrbia harti ewing and tetranychus urticae. The acaricide comprises the following raw materials in percentage by weight: 1.0 to 50.0 percent of cnidium oil, 1.0 to 50.0 percent of wintergreen oil and the balance of various auxiliary agents. The plant source synergistic complex acaricide has the characteristics of no chemical pesticide component, low toxicity to human beings and animals and environmentally friendly, capability of preventing and controlling various mites on fruit trees, vegetables and flowers, and extremely high application and popularization values on organic crops, so the plant source synergistic complex acaricide is a novel non-pollution acaricide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to an acaricide with two plant-derived substances, chuanxiong oil and wintergreen oil, as active components and a preparation method thereof. Background technique [0002] Acarids (mites) belong to Arthropoda (Arachinida), Arachnida (Arachnida), Acari subclass (Acari). According to its economic significance, it can be divided into two categories: medical and animal husbandry acarids and agricultural acarids. Among them, the important agricultural mite pests are concentrated in 6 families of Acariformes, among which the most important mite damage is Tetranychus mites, followed by Hypophyllid mites, Eriodous mites, Nematode mites and Acarid mites. Among them, spider mites are the largest group of agricultural mite damage. There are more than 200 species in 16 genera known in my country; there are more than 180 species of gall mites recorded in my country; the serious da...
