Embodiment 1

[0058] Example 1: Indoor combined toxicity study of Chuanxiong oil and lemongrass on apple yellow aphid

[0059] 1.1 Materials and methods

[0060] 1.1.1 Test insects

[0061] Apple yellow aphid ( Aphiscitric lavander Goot ), and the Pollution-Free Pesticide Research Service Center of Northwest Agriculture and Forestry University.

[0062] 1.1.2 Drugs to be tested

[0063] A. Ligusticum chuanxiong oil, provided by Guangxi Hengxin Spice Company, with a ligustilide content of >35%.

[0064] B. Lemongrass oil, provided by Guangxi Hengxin Fragrance Company, with a citral content of >75%.

[0065] 1.2 Determination method

[0066] 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 it out, absorb the drug solution with absorbent paper, and ...

Abstract

The invention discloses botanical synergistic compound aphicide. The prepared botanical synergistic compound aphicide is compounded by Szechuan lovage rhizome oil and lemongrass oil serving as main components and an added aid; the form of the preparation is creaming agent, microemulsion or aqueous emulsion; and the preparation contains 5.0 to 50.0 percent of Szechuan lovage rhizome oil, 1.0 to 50.0 percent of lemongrass oil and the balance of aid. The aphicide is mainly used for preventing and controlling aphids such as apple yellow aphid, cabbage aphid, macrosiphoniella sanborni, Chinese wolfberry and the like on fruit trees, vegetables and flowers. The botanical synergistic compound aphicide does not contain any chemical pesticide components, has low toxicity to people and animal, is environment-friendly, can prevent and control various aphids on the fruit trees, vegetables and flowers, has great application and popularization values on production of organic agricultural products, and is ideal novel harmless aphicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to an aphidicide with two plant-derived substances, chuanxiong oil and lemongrass oil, as active components and a preparation method thereof, which is mainly used for preventing and treating apple yellow on fruit trees, vegetables and flowers. Aphids, cabbage aphids, chrysanthemum aphids and wolfberry aphids. 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, and harm to human health. Searching for aphidicidal active substances from the treasure house of natural resource...
