2. Organic Phosphorus Series

(1) Dimethoate

Mechanism and characteristics

Dimethoate is a broad-spectrum, systemic insecticide and acaricide. Oxidized in insects to highly toxic omethoate, which is an acetylcholinesterase inhibitor, hinders nerve conduction and causes insect death. It is suitable for the prevention and control of piercing and sucking mouthparts pests on a variety of crops, such as aphids, leafhoppers, whiteflies, leaf miners and certain scales and mites.

3. Others

(1) Imidacloprid

Mechanism and characteristics

Nitromethylene systemic insecticides are agents of nicotinic acid acetylcholinesterase receptors. They interfere with the motor nervous system of pests and cause chemical signal transmission to fail without cross-resistance problems. Used to control piercing and sucking mouthparts pests and their resistant strains.

Control object

Mainly used to control piercing and sucking mouthparts pests on rice, cotton and other crops, such as aphids, leafhoppers, thrips, whitefly, potato beetles and wheat stalk flies, and also used to control fruit tree pests such as spiraea aphid, Pests such as apple tumor aphid, myzus persicae, pear psyllid, leaf roller, whitefly, and Liriomyza.

The drug is a new type of high-efficiency, low-toxic and broad-spectrum insecticide. It is a second-generation neonicotinoid insecticide. Its mechanism of action is similar to that of the first-generation neonicotinoid insecticide such as imidacloprid, but it has higher activity. It has stomach poisoning, contact killing, systemic effects on pests, fast action speed and long lasting effect. It has better control effect on piercing and sucking pests such as aphids, planthoppers, leafhoppers and whiteflies.

Control object

It can effectively control Lepidoptera, Coleoptera, Thysanoptera and Homoptera pests, such as: aphids, leafhoppers, whiteflies, planthoppers, mealybugs, scarab larvae, potato beetles, thrips, jumping beetles, ground beetles, Leaf miner and so on.

(3) Fipronil

Mechanism and characteristics

Also known as fipronil, a phenylpyrazole insecticide. It has a wide insecticidal spectrum, which mainly hinders the fluoride metabolism controlled by γ-aminobutyric acid in insects, and has high insecticidal activity against a series of important pests such as lepidoptera, flies and coleoptera. Contact, stomach poison, internal aspiration

Control object

Fipronil is a broad-spectrum insecticide with outstanding control effect against many kinds of pests. It is against Hemiptera, Lepidoptera, Thysanoptera, Coleoptera and other pests, as well as against cyclopentadiene, chrysanthemum Pests to which esters and carbamate insecticides have developed resistance are extremely sensitive.

It is also effective for preventing and controlling mites that are resistant to other acaricides. After medicine, it can control the number of harmful mites for a long time.

Control object

Mites, aphids, scale insects, cotton bollworms, red bollworms, psyllid psyllid, orange whitefly and acarids outside of livestock.

The properties of pesticides are different, and the methods of application are also different. In addition to general application methods, systemic conductive pesticides also have unique application methods. Research on the use of systemic pesticides and make full use of their systemic conductivity is of great benefit to agriculture and forestry production.
