Embodiment 1

[0059] Example 1: Indoor combined toxicity study of nicotine and turpentine on apple yellow aphid

[0060] 1.1 Materials and methods

[0061] 1.1.1 Test insects

[0062] Apple yellow aphid ( Aphis citricola van der Goot ), collected from an apple orchard in Dazhai Township, Yangling, Shaanxi.

[0063] 1.1.2 Drugs to be tested

[0064] A. Nicotine, provided by the Pollution-free Pesticide Research Service Center of Northwest A&F University;

[0065] B. Turpentine was provided by Shiwanshan Forest Chemical Plant, Shangsi County, Guangxi Province.

[0066] 1.2 Determination method

[0067] Indoor bioassay of aphids was carried out by dipping insects and leaves. Dilute the test agent with water into the mother solution first, and then dilute it into 6~7 concentration gradients, then soak the selected test insects and leaves in the drug solution for 5 seconds, take out the drug solution with absorbent paper, and put it in the pre-moisturizing solution. In a 9cm ...

Embodiment 2

[0101] Embodiment 2: 10% nicotine · turpentine emulsifiable concentrate preparation

[0102] At 20~25°C, take 10 parts of nicotine and turpentine (the compounding ratio of nicotine and turpentine is 1:3), add 6 parts of silicone, 12 parts of diesel oil, and 4 parts of dodecane on the basis of the above mixture. Sodium phenyl sulfonate and 1 part of octylphenol polyoxyethylene ether and 1 part of phenylethylphenol polyoxyethylene polyoxypropylene ether, make up to 100 parts with ethanol + ethyl acetate (3.5:6.5), and stir at a speed of 800 Stir at ~1000 rpm for 10-30 minutes to prepare 10% nicotine-turpentine emulsifiable concentrate.

Embodiment 3

[0103] Embodiment 3: 20% nicotine · turpentine emulsifiable concentrate preparation

[0104]At 20~25°C, take 20 parts of nicotine·turpentine (the compounding ratio of nicotine and turpentine is 1:3), add 8 parts of silicone, 16 parts of diesel oil, and 5 parts of dodecane on the basis of the above mixture. Sodium phenyl sulfonate and 1 part of octylphenol polyoxyethylene ether and 2 parts of phenethylphenol polyoxyethylene polyoxypropylene ether, make up to 100 parts with ethanol + ethyl acetate (3.5:6.5), and stir at a speed of 800 Stir at ~1000 rpm for 10-30 minutes to prepare 20% nicotine-turpentine emulsifiable concentrate.

Abstract

The invention discloses a nicotine-containing botanical synergist compound insecticide which is prepared by using nicotine and turpentine as main components and adding an assistant through compounding. The forms of the nicotine-containing botanical synergist compound insecticide comprise environment-friendly missible oil, microemulsion or emulsion in water; and the nicotine-containing botanical synergist compound insecticide comprises the following components: 1.0-50.0% of nicotine, 5.0-40.0% of turpentine and the balance of the assistant. The nicotine-containing botanical synergist compound insecticide does not contain any chemical pesticide component, has low toxicity to people and livestock, is environment-friendly, and is mainly applied to control of aphids such as Aphis citricola vonder Goot, brevicoryne brassicae, macrosiphoniella sanborni, Aphis gossypii Glover and the like on fruit trees, vegetables and flowers and empoasca flavescens on commercial crops such as mulberry, teaplants, peach trees, pear trees, cotton, tobacco, hemps and the like. The nicotine-containing botanical synergist compound insecticide has great application and popularization values of organic agricultural products in the production, and is a novel ideal pollution-free insecticide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to an insecticide with two plant-derived substances, nicotine and turpentine, as active components and a preparation method thereof, and is mainly used in the prevention and treatment of apple yellow aphids on fruit trees, vegetables and flowers, Aphids such as cabbage aphid, chrysanthemum aphid and wolfberry aphid, and small green leafhoppers of economic crops such as mulberry, tea, peach, pear, cotton, tobacco, and hemp. Background technique [0002] Aphids are important agricultural pests and have the characteristics of fast reproduction, large numbers, many types, severe damage and wide range of damage, so it is difficult to control them. At present, chemical agents are mostly used for the prevention and control of aphids. However, a large number of chemical drugs for a long time have led to the emergence of problems such as drug resistance, environmental pollution...
