Problems solved by technology

As a kind of medicament we use daily, perilla leaf is commonly found in various traditional Chinese medicine preparations such as Huoxiang Zhengqi Oral Liquid, Children Qingfei Tablet, etc. However, the deworming and sterilization effects of perilla leaf are often ignored by people, but Currently less research
Lemongrass is currently widely used as an enhancer of pyrethrins to improve the insecticidal effect of pyrethrins, but its repellent effect on insects such as weevil, corn weevil, American cockroach, and Aedes aegypti is often used by people. neglected

[0047] A kind of plant-derived essential oil composition for controlling wheat aphid

[0048] The source of insects: Aphis spp. and Aphis vulgaris were collected from a wheat field, an experimental field of Henan University, Kaifeng City, Henan Province, China (114°30′N, 34°81′E). Insect sources were collected by collecting leaves with aphids and reared in artificial climate boxes. The setting parameters of the climate box are: the day-night time ratio is 71% light, the temperature is 21°C, 14h:10h, and the humidity is 86%. Fresh wheat seedlings are used for cultivation.

[0049] Extraction of essential oils: Place 500g of the stems, leaves of perilla leaves and necks of lemongrass purchased from Anguo Chinese Herbal Medicine Market (Anguo, 071200, Hebei Province, China) into a 3000ml round-bottom distillation bottle, and add 2000ml of distilled water , carry out heating distillation, until there is no distillate dripping out of the condensation tube, replace with a new disti...

Abstract

The invention discloses a plant-derived essential oil composition for controlling wheat aphid. The plant-derived essential oil composition is prepared from the above-ground tissues of perilla leaves, lemongrass and Nepeta according to the method of mixing 2 parts, 1 part and 2 parts, and then transferring water vapor fractionation. Take the mixed essential oil to obtain a plant-derived essential oil composition. The main control objects of the plant-derived essential oil composition provided by the invention are common aphids in wheat. The plant-derived essential oil composition is derived from plant essential oils, has high efficiency and environmental protection, has no toxic and side effects on plants and application groups, has high safety, and has low preparation cost. When the concentration of spraying on plants is not less than 300ppm, the mixed preparation has the greatest control effect on common aphids in wheat fields, reaching 86-92%, and the control effect on wheat aphids increases with time.

Description

technical field [0001] The invention belongs to the technical field of agricultural pest prevention and control, and discloses a plant-derived essential oil composition for controlling wheat aphid. Background technique [0002] The wheat aphid is a worldwide pest of wheat (Triticum aestivum). They not only cause direct feeding hazards to plants, but also transmit plant viruses during the feeding process, thereby causing disease hazards to the host. In order to protect the normal growth of wheat, it is necessary to apply a large amount of chemical pesticides to ensure crop yields. However, the use of a large number of chemical agents not only increases the cost of crop production, but also increases pesticide residues in wheat, destroying the balance of the natural ecosystem. Therefore, more and more plant protection experts try to develop safer and more reliable new pesticides to replace traditional pesticides through various means. Botanical insecticides, as currently re...
