Abstract

The invention belongs to the technical field of botanical pesticides and particularly relates to a pesticidal insecticide containing vetiver grass, and a preparation method and application of the pesticidal insecticide. The pesticidal insecticide is prepared from the following materials in parts by weight: 12 to 20 parts of vetiver grass herba extract, 5 to 10 parts of pyrethrum cinerariifolium, 3 to 5 parts of tuberostemonine, 60 to 100 parts of alcohol solution, 15 to 35 parts of glycerinum and 80 to 120 parts of water. The pesticidal insecticide has the advantages that the source of plant materials is wide, the toxic and side effects to a human body are less, insects cannot easily generate resistance to the insecticide, the cost is low, the environmental-friendly effect is achieved, the extraction of effective components in all plant materials is complete, the formula is reasonable and the preventing and controlling effects on insect damage are obvious.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a vetiver-containing pesticide and insecticide, a preparation method and application thereof. Background technique [0002] In recent years, there have been reports of cherry maggots (fruit fly larvae), causing panic among consumers, seriously affecting consumers' confidence and desire to buy, and causing great losses to the cherry industry. Fruit flies not only harm cherries, but also harm peaches, European plums, grapes, strawberries, raspberries, blueberries, persimmons, tomatoes and other fruits and vegetables. The female fruit fly's ovipositor is hard and serrated, and can lay eggs directly in fruits with soft skins such as cherries and peaches that are ripe or about to mature. The larvae feed on the fruits, causing serious losses to the orchard. In particular, myrica rubra has a more serious impact on late-maturing varieties and alpine bayberry, directly cau...
