1. Insecticides and acaricides?
(1) Nicotine-based insecticides?
First generation: chlorinated nicotine type: the earliest It was imidacloprid produced by Germany's Bayer, followed by imidacloprid (mobiran, acetamiprid) produced by Japan's Soda Company. In 2001, Bayer Company launched thiacloprid. Nantong produces 10 and 40 chlorothioline wettable powders.
Second generation: thionicotine: 25 Acta (Thiamethoxam) produced by Swiss Syngenta Company, with a usage ratio of 8000-10,000 times. The knockdown effect of this drug is not as good as imidacloprid, but it has good systemic effect and long residual effect period, and can be used for dry treatment. On fruit trees, it can replace omethoate and methamidophos, with a concentration of 150 times.
In 2002, Japan's Takeda Company produced clothianidin. ?
The third generation: furan-type nicotine: 20 dinotefuran water dispersant, produced by Mitsui Company of Japan, has broad spectrum and good systemic effect. It can not only be used to control aphids, scales and other pests, but also leaf-mining pests. ?

1. Indoxacarb: 15 hits (suspension) 3000 times liquid, 30 hits (suspension 6000 times liquid). This drug is an antifeedant for insects. , insects immediately stop moving after contact, fall to the ground, and die after about 5-7 days. It is mainly used to control moth pests, especially resistant pests. It is a very effective pesticide produced by DuPont Company in the United States.
2. 20m Man (suspension agent) (fenfenozide, fenfenozide) 1500, produced by Dow Company of the United States. It is a peeling accelerator for arthropods. It is mainly used as a stomach poison to control moth pests and is used during the flowering period. To control small leaf rollers after flowering.
3. Domestic: 10-fold furenazide (Fuxian) suspension, 500-600 times the same effect as Miman?
4. , Methoxyfenozide, produced by Bayer Company, is more effective than Miman?
(4) Nereitoxin?
90 insecticidal wettable powder, 1500. 50 times liquid, 1500 times liquid, 20 times liquid insecticide, 600 times liquid. The effect decreases in sequence, but the safety is improved. This type of pesticide is a contact insecticide, but has strong penetration. , can be used to control leafminers and leafminers, and can be used on fruit trees as an alternative to 1605 in the early stages of fruit borer damage.
(5) Acaricides?
1. 24 fenaceb (fenacetate, spirodifenacet, fenacetate) suspension agent, the dosage is 5000-6000 times, produced by Bayer. It has poor knockdown effect on adults and takes effect after 5 days, but it is effective on eggs and nymphs. It is highly effective. It has a long lasting effect of up to 60 days. Compared with Nisolan, the effect of 6000 times solution after 30 days is 82.2. Although the drug has poor knockdown effect on adult worms, it has an anti-feeding effect.
2. 30-day Danon (pyrimidin) suspension, using 4000 times solution, is produced by Japan's Soda. p>
3. 20 Flufentrazine suspension, use 3000 times solution, produced in Hungary. The quick-acting effect is better than that of Trifenac, but the lasting effect is worse, but it is higher than that of Nisolan. The effect after 3 days can reach 99%, but The effect is poor at low temperatures. ?
4. 10-fold aphrodisiac suspension agent, 3000 times liquid. The mechanism of action is the same as that of the American Dow Company.
?
In addition, there are: 10% dichloride (bromiphenil), 3000 times liquid, produced by Bayer. Pesticides that treat both insects and mites are not as effective as abamectin. 2 Russell's method (flumethrin), 1500 times liquid, is used to replace scavengers and treat both insects and mites.
2. Fungicides?
(1) Triazoles?
New triazole pesticides have an expanded bactericidal spectrum and can be used to prevent and treat a variety of diseases , at the same time, its inhibitory effect on plants is greatly reduced, and phytotoxicity is reduced. This type of pesticide can be used to control powdery mildew and rust. In addition, it can also be used to control the following diseases.
1. 40 Fuxing (fluorosilicone) emulsifiable concentrate, produced by DuPont in the United States, use 8000-10,000 times of solution. It can be used to prevent and control pear scab, apple spotted leaf disease, and tomato leaf mold. ?
2. Syngent, Switzerland, has reached production capacity of 10th Shigao (Oxafenazole) wettable powder and is currently producing it locally. Use 3000x solution. Used to prevent and control grape white rot, vegetable blight and round spot root rot of fruit trees. ?
3. 30% Teflon (trifluconazole) wettable powder, use 2000 times of solution, produced by Soda, Japan. It is highly effective against powdery mildew and can be used to control strawberry powdery mildew. ?

5. 43 Horlicks (tebuconazole) EC is produced by Bayer and has been domestically produced. Use 3000x solution. It can be used to prevent and control pear scab, grape white rot, anthracnose, apple ring disease, etc. Compared with fentanyl, its effectiveness in controlling apple ring spot and anthracnose is equivalent, and its prevention and control of grape white rot is 4 times higher. However, its effectiveness in controlling apple spot defoliation is worse than fentanyl.
(2) Methoxyacrylate fungicides?
1. 25 Amicida (imistrobin) emulsifiable concentrate, Syngent reaches production, use 1500 times of solution. ?
2. 50% Tribet (azoxystrobin) wettable powder, produced by BASF. Use 3000x solution. Its effectiveness in preventing and controlling various diseases is compared with that of fentanyl: ?
The effectiveness of apple ring disease is 3.4 times higher, that of apple anthracnose is 1.5 times higher, and that of grape white rot is 2.3 times higher. Apple speckled leaf disease is worse than hyacinth. ?
3. 30% azoxystrobin wettable powder, domestically produced, use 1500 times of solution. ?
The three chemicals are basically one ingredient. This type of medicine has a very broad bactericidal spectrum and can also be used to prevent and treat diseases caused by lower fungi, which often require specialized chemicals. The problem with this type of medicine is that it is expensive and prone to drug resistance.
(3) Bactericidal agents?

The drug contains 3.8 inorganic copper, which can play a protective role; it also contains a thiazole group, which has a systemic therapeutic effect. Therefore, it is a pesticide that has both a protective effect and a systemic therapeutic effect. Because it contains inorganic copper, it also has a protective effect against some fungal diseases. This medicine is safe to use. It is the first choice agent for preventing and treating bacterial perforation diseases of stone fruits.
3. 20% thiazole zinc wettable powder, use 500-600 times of solution, which has protective and systemic treatment effects. ?
