Stupid and unclear pesticides

Recently, I received feedback from many farmers: Many names are similar, and pesticides with similar pronunciations are often confused, leading to the use of wrong medicines! Damaged ladies (tickets) and discounted soldiers (crops), so today Xiaobian is here for everyone. Classification and introduction of several pesticides with very similar names:

01. Thiobacillus copper

Copper thiabium, chemical name: "2-amino-5-mercapto- 1,3,4-thiadiazole copper", the trade name is "Dragonella". It is a low-toxic thiazole organic copper fungicide .

Can prevent diseases:

(1) Bacterial diseases: rice bacterial leaf spot, rice bacterial blight, rice-based rot, citrus canker, grapefruit canker, cucumber bacterial angular leaf spot, cotton leaf spot, garlic leaf blight , Melon keratosis, cabbage soft rot, peanut bacterial wilt, tobacco wildfire, tobacco bacterial wilt, konjac soft rot, ginger ginger rot, pepper bacterial wilt, bacterial seedling bacterial disease, peach tree bacterial perforation Sick and so on.

(2) fungal diseases: citrus scab, grapefruit scab, banana leaf spot, watermelon blight, longan leaf spot, peanut blight, grape black pox, apple ring disease, pear anthracnose, tomato Fusarium wilt, sesame wilt disease, etc.

Characteristics: In the bactericidal mechanism of thiabium copper, both thiazolyl groups have unique control effects against bacteria (thiazole groups are highly effective therapeutic agents in plants), and copper ions have excellent control effects on fungi and bacteria, while internal absorption Good performance, with good dual treatment and protection. According to the efficacy of the drug, the 20% thiabend copper suspension can be used for 10 to 14 days under normal dosage. At the same time, since the effective copper content of thiabium copper is 3.9%, phytotoxicity is rarely produced. At the same time, in the actual use of Daejeon, the residual amount of copper does not exceed the residual allowable standard.

02. Thiacinone

Thiacinone, chemical name "5-(4-chlorophenyl)-3-(N-cyclohexylcarbamoyl)-4-methylampythiazolidine-2-one", also known as "Nisolang" , dosage form: 5% emulsifiable concentrate, 10% wettable powder

Control objects: Thiacinone can control leafhoppers (red spiders) on a variety of crops such as fruits, forests, tea, cotton, vegetables, beans, flowers, etc., but has poor control effect against rust and cockroaches.

Characteristics: It has strong contact and stomach toxicity to the mites; it has strong osmotic effect on the epidermis of the crop, but has no systemic effect; it is effective against cockroaches, nymphs and young pupa, and has little virulence to cockroaches. The hatching rate of the eggs that are exposed to the drug is low; the drug effect is slow, and the drug effect peak is generally reached 7 to 10 days after the application, and the effect period is 40 to 50 days; but at high temperature and high humidity. Under the conditions, the high concentration of spraying has slight phytotoxicity to the young shoots of some crops. It can be mixed with a variety of pesticides such as Bordeaux liquid and stone sulfur mixture.

03. Tamidone

Thiazolone is an organic heterocyclic fungicide with the chemical name "12 Benzoisothiazolin-3-one". The related products are fine 3% thiazolone dry suspension and easy to remove 1.6% thiazolone spreader. .

Targets for prevention and treatment: thiazolone has a broad spectrum of sterilization, and can effectively prevent rice sheath blight, bacterial stripe disease, rice smut, bacterial blight, flax leaf spot, wheat powdery mildew, scab, rust, vegetable bacteria Sexual plaque, anthracnose, rust, powdery mildew, leaf spot, etc.

Features: It has the dual functions of protection and treatment. It can protect the healthy plants from infection by pathogens before the onset of the disease. Increasing the dosage can increase the spread of the disease after the onset of disease. It has multi-directional sterilization sites, and the bacteria are not easy to produce drug resistance; the active ingredients can be Slow release, combined with quick-acting and long-lasting effect; while controlling diseases, it can effectively promote crop growth, increase fruit set rate, and increase yield and quality. At the same time, the mixture of thiamethane is good, and it can be mixed with most pesticides except strong acid and alkali. It also has synergistic effect with the same type of medicine, which can significantly improve the activity of the drug and achieve twice the result with half the effort.

04. Buprofezin

Buprofezin chemical name "2-tert-DING Ya-amino-3-isopropyl-5-phenyl-tetrahydro -2H-135- -3456- thiadiazine-4-one", is an insect growth regulator agents kill Insecticides , the preparation types are: 5%, 20%, 25%, 65% wettable powder, 25% suspension, 5% emulsifiable concentrate, 8% film-forming oil.

Targets for prevention and control: It can effectively control the large leaf family of the genus Euphorbiaceae, the genus Euphorbiaceae on the rice; the genus Polygonaceae on the citrus, cotton and vegetables; the genus Polygonaceae, the genus Diptera and the whitefly on the citrus Branch and so on.

Features: 1. It has strong selectivity to pests, and it is effective only for the genus Heliconia, spider mites, whiteflies and scale insects of Hemiptera, but for rice blast, rice leaf roller, cabbage caterpillar and side dish Pests and other pests are ineffective and safe for natural enemies. It is an ideal pesticide variety in the current integrated pest control.

2. It has a strong contact effect on pests and a strong stomach toxicity. It has certain permeability to crops and can be absorbed by rice leaves or sheaths, but it can not be absorbed by roots. It has strong ability to kill younger nymphs, and has a significantly reduced ability to kill nymphs above 3rd instar. It has no direct poisoning effect on adults. . However, the lifespan of the adult can be shortened, the amount of eggs laid can be reduced, the hatching rate of the eggs produced is lowered, and the hatched larvae are quickly killed, thereby reducing the number of occurrences of the next generation.

3, the drug effect is slow, generally 3 to 5 days after application. The nymphs begin to die when they are minked, and the number of deaths reaches the highest peak 7 to 10 days after application. Therefore, the efficacy period is long. Generally, the insect control period is about 15 days. In addition, the natural enemies are protected and the natural enemies control the pests. , so the total validity period can be up to 1 month.

05. Thiabendazole

Thiabendazole is a benzimidazole fungicide with the chemical name "2-(4-thiazolyl)-1H-benzimidazole". Dosage form: 45% suspension, 60%, 90% wettable powder, 42% suspension.

Control object: thiabendazole is mainly used for scutellaria and citrus blue mold, green mold, flower rot, and has good anti-aging effect on fruit rot; it can also be applied to mushrooms, strawberries, celery, cabbage, apples, Duguo, pear, etc., used to treat brown rot, powdery mildew, gray mold, sclerotinia, spot blight, anthracnose, ring disease, green disease, black spot disease and other diseases.

Features: High-efficiency, broad-spectrum, systemic fungicide, both protective and therapeutic. It can conduct to the top but not to the base. It has a long-lasting effect and is resistant to cross-linking with benzimidazole fungicides.

06. Thiabendazole

Thiabendazole, chemical name "2-benzoyl hydrazone-13-dithiane", common dosage forms: 20%, 25%, 40% wettable powder.

Control object: Thiabendazole can control bacterial diseases such as tobacco bacterial wilt, wildfire disease and angular spot disease.

Characteristics: Thiabaptoin is a broad-spectrum, systemic organic sulfur fungicide that has a control effect on bacterial diseases of various crops. It has both preventive and therapeutic effects, high efficacy, long-lasting effect, low residue, resistance to rain erosion, stable drug effect, and less susceptible to phytotoxicity.

(The current academic research on thiabendazole and related materials is rare)

07. Thiessen Copper

Thienson copper, chemical name "N, N'-methylene-bis-copper", is a thiazole-based organic copper bactericide, common dosage form: 20%, 30% suspension.

Control objects:

(1) Rice: bacterial blight, bacterial stripe disease, stem-based rot, rotten rot disease, bacterial brown spot disease, and the like.
