Problems solved by technology

However, scraping off the bark is both troublesome and harmful to the trees, while the dichlorvos used to kill noctuids is too toxic, which is harmful to operators and garden viewers
Although more drugs to kill noctuids have been developed in the follow-up, there are few drugs that are less toxic to humans and can effectively kill noctuids.

Embodiment 1

[0013] Add fresh tender leaves of Artemisia annua to 10 times the amount of water, homogenize and then filter to obtain the filtrate, put the filtrate on a D101 macroporous resin column, the weight of the macroporous resin filler is 30 times the weight of the dry paste of the filtrate, first use 70% ethanol Elution was performed for 10 times the column volume, followed by washing with 75% ethanol for 5 times the column volume, and the 75% ethanol eluent was combined, and the solvent was removed to obtain the Artemisia annua preparation. Take the preparation of Artemisia annua, dissolve it in 30 times the amount of methanol, filter it with a 0.22um filter membrane, take the filtrate, and put it into a semi-prepared high-performance liquid phase. The detection wavelength is 292nm and tracked by mass spectrometry. h, the mobile phase is changed from methanol to water 3:7 to methanol to water 9:1, collect the eluate with a molecular weight signal of 326.1366 in a period of 12-15 mi...

Abstract

The invention belongs to the technical field of pest control in gardens, and relates to a compound for preventing and controlling armyworms in gardens and its application. The fresh young leaves of Artemisia annua were extracted with water, the macroporous resin was separated, semi-preparative high performance liquid phase was tracked and prepared, and the compound was obtained by recrystallization, named as artemisinin acid, which was a new compound. The compound of the present invention for controlling noctuid moths in gardens comes from the natural medicine Artemisia annua. As a medicine, its extract has been used clinically for many times, has no obvious side effects on the human body, and has good safety. Artemisinic acid has a good killing effect on noctuid, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of pest control in gardens, and in particular relates to a compound for preventing and controlling armyworms in gardens and its application. Background technique [0002] Noctuid refers to a class of insects in the Noctuidae family, mostly herbivorous pests, and a few species prey on other insects. Some species have strong beaks, which can pierce the fruit skin and suck juice, and a few species can suck human and animal secretions. When many species of Noctuidae occur in large numbers, they will cause great damage to trees and crops. For example, the larvae of Spodoptera spp. will damage the leaves of plane tree, citrus, hibiscus, hibiscus, Pittosporum, mango, hibiscus, mallow and hibiscus, eating all the leaves, leaving only the veins, affecting the ornamental effect of flowers and trees . There are also leaf roller moths, which also harm fruit trees such as apples, shaguo, peaches, pears, and plums. Whe...
