Plant extract: Cnidium monnieri is a substance extracted from the fruit of Cnidium monnieri monnieri , an annual herb in the Apiaceae family, with a yellow-green to white crystalline powder in appearance, insoluble in water
。 Cnidium monnieri is a class of coumarin compounds first extracted and isolated from plants in the Apiaceae family, and the dried mature fruit Cnidium monnieri (Fructuscnidii) of the Apiaceae plant snakebed is relatively high, hence the name
.
Relevant studies have shown that Cnidium monnieri also exists in a variety of other plants, mainly including Apiaceae plants such as Dangdang, Gudang, and Cnidium monets, as well as rutaceae plants such as citrus, yellowbark, elephant tangerine, and rutae, and is also distributed
in a few species of Asteraceae and legumes.


Cnidium monnieri specifications: in terms of the effective content of Cnidium monnieri content, it can be divided into crude extract 10%-60%; Secondary fine extraction: 70%-98%
Cnidium monnieri is also known as methoxyparsmol or parsel methyl ether (osthole, Ost), its chemical name is 7-methoxy-8-isoprenyl coumarin, and the core structure is composed of
benzene ring and pyranone ring.
As a member of coumarin, Cnidium monnieri not only has the core structure of coumarin, but also has an isoprene structure, and isopentene structural compounds play an important role
in disease resistance as phytoprotectins.


Cnidium monnieri is a plant-derived insecticide, its mode of action is mainly contact killing effect, supplemented by gastric toxicity, the liquid is absorbed into the insect body through the body surface, acting on the nervous system of pests, resulting in non-functional contraction of pest muscles, and eventually failure and death
.
The indoor virulence measurement test showed that it had high activity against cabbage cyanobacteria (LD50 was 6.
2258mg/kg).

Field efficacy tests have shown that it has a good control effect
against cruciferous vegetable greenworm and tea tree tea inchworm.
The dosage of cruciferous vegetable greenworm is 4.
8~7.
2g/h㎡ (converted into 0.
4% Cnidium monnieri emulsion 80~120mL per mu of land); The amount of active ingredient for the prevention and control of tea tree beetle is 6~7.
2g/h㎡ (converted into 0.
4% Cnidium monnieri emulsion oil commodity amount of 100~120mL per mu of land).

Generally, the amount of liquid per mu is 50~75kg, uniform spray; The validity period is about
7d.
It is safe for crops within the dosage range, and no drug damage
has been found.
