Embodiment 1

[0048] Example 1: Indoor combined toxicity study of matrine and lemongrass oil on peach aphid

[0049] 1.1 Materials and methods

[0050] test insect

[0051] The green peach aphid (Myzus persicae) was bred at the Plant Source Pesticide Engineering Technology Research Center of Fuji Biotechnology Development Shanghai Co., Ltd.

[0052] Test drug

[0053] A. Matrine, provided by Shaanxi Angsheng Biomedical Technology Co., Ltd.

[0054] B. Lemongrass oil, provided by Guangxi Hengxin Spice Company, with a citral content of >78%.

[0055] 1.2 Determination method

[0056] Determination of biological activity of aphids indoors: use the leaf-soaking method recommended by FAO to remove winged aphids, select healthy adult aphids without wings of the same size for the test, and set up a clean water control. If the control mortality rate is higher than 20% in the test, the This test is void.

Embodiment 2

[0089] Example 2: Preparation of 50% Matrine Lemongrass Oil Environment-friendly EC (1)

[0090] At 20-25°C, take 50 parts of matrine and lemongrass oil, the compounding ratio is 1:3, add 10 parts of organic silicon, 20 parts of soybean oil and 3 parts of dodecylbenzene on the basis of the above mixture Sodium sulfonate and 7 parts of octylphenol polyoxyethylene ether are stirred at a stirring speed of 800-1000 rpm for 10-30 minutes to prepare 50% matrine·lemongrass oil emulsifiable concentrate.

Embodiment 3

[0091] Embodiment 3: 30% matrine·lemongrass oil-in-water emulsion preparation

[0092] At 20-25°C, take 30 parts of matrine and lemongrass oil, the compounding ratio is 1:3, add 2 parts of organic silicon, 6 parts of nonylphenol polyoxyethylene ether, nonylphenol 3 parts of polyoxyethylene ether phosphate, 5 parts of glycerin, after mixing evenly, add 100 parts of aqueous solution containing 0.05% xanthan gum to make up 100 parts, and stir for 20 minutes at the speed of high-speed shearing machine at 10,000 rpm to obtain 30 % Matrine Lemongrass Oil-Water Emulsion.

Abstract

The invention relates to an aphid biocide, and particularly relates to a hicide caphidicide containing sophocarpidine and a preparation method of the hicide caphidicide. According to a compound preparation containing sophocarpidine and lemongrass oil, the form of the preparation can be environment-friendly missible oil, a microemulsion and a water emission; the compound preparation contains the following raw materials: 1.0%-50.0% of sophocarpidine, 1.0%-40.0% of lemongrass oil, 0-20% of an environment-friendly solvent and 5%-20% of a surfactant; other assistants comprise a synergist, a penetrating agent and a thickening agent; and the composition of the microemulsion and the water emission is supplemented with water to 100% besides of containing the raw materials. The synergistic compound hicide caphidicide containing the sophocarpidine does not contain any chemical pesticide component, so that the synergistic compound hicide caphidicide is low in toxicity on people and animals, and friendly to environment, has great application and promotion value in planting of organic crops and green crops, and is a novel harmless insecticide; and various aphids on fruit trees, vegetables, traditional Chinese medicinal materials and flowers can be prevented and treated.

Description

technical field [0001] The invention relates to an aphid killing agent, in particular to a matrine-containing aphid killing agent and a preparation method thereof. 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 in the prevention and control of aphids in traditional agriculture, which has caused problems such as drug resistance, environmental pollution, and harm to human health. However, the demand for botanical pesticides in organic agriculture is becoming increasingly urgent. Therefore, searching for aphidicidal active substances from the treasure house of natural resources is becoming an important way and research hotspot for the creation of new aphidicides. Especially through the scientific compounding of multiple ingredients, the effect of plant-derived...
