Thiamethazide is a new kind of second-generation nicotinic insecticide with high efficiency and low toxicity, which has gastric toxicity, palpation and internal absorption activity against insect pests. It is quickly absorbed and transmitted to all parts of the plant, and has a good control effect on spiny and sucking pests such as aphids, planthoppers, leafhoppers and mealworms.
Mechanism of action:
Similar to imidacloprid, it can selectively inhibit nicotinic acid acetylcholinesterase receptors in the insect central nervous system, thereby blocking the normal conduction of the insect central nervous system, resulting in the death of the insect when it is paralyzed. It is a better variety of organophosphorus, carbamate and organochlorine insecticides which are highly toxic to mammals and have residues and environmental problems.
It is highly active in coleoptera, diptera, lepidoptera, especially homoptera pests, and can effectively prevent and control aphids, leafhoppers, planthoppers, whiteflies, beetle larvae, potato beetles, nematode worms, ground beetles, cryptoptera and other pests that are resistant to a variety of chemical pesticides.
There was no interaction resistance with imidacloprid, amidine and alenolamide. It can be used for stem and leaf treatment, seed treatment and soil treatment. The suitable crops are rice crop, beet, rape, potato, cotton, bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus. The recommended dose is safe and harmless to crops.
Do not mix with alkaline agents. Don't below minus 10 ℃ and 35 ℃ higher than the storage environment. Bees are poisonous, so you should pay special attention to them. The insecticidal activity of this medicine is very high, do not blindly increase the dosage of medicine.
Acrylone is a stem and leaf herbicide, and is a highly effective, safe and selective ACase inhibitor. It is especially effective for most annual and perennial grasses and safe for dicotyledon crops.
Crops such as soybean, peanut, rape, cotton, flax, tobacco, a variety of broad-leaved vegetables, grapes, citrus, apples and other plantations.
1. It is best to make mother liquor for preservation. 2. Oenoxanone is easy to decompose in the presence of water, so it should be strictly controlled. 3. Enthalone is easily decomposed by polar solvents 4. Oenoxanone is easily decomposed by light, so it should be kept away from light when stored. 5. Enthalone is easily decomposed by alkaline solvents. The original drug was acidic PH=4-6| 6. The decomposition of enoxanone was obviously accelerated when the temperature was higher than 20 degrees Celsius, and the storage temperature was 3-8 degrees Celsius. 7. Oleacetone preparations prepared by long-term stored crude drugs are prone to flocculent impurities, and fresh crude drugs will not appear. Therefore, it is suggested that the crude drugs should not be processed into preparations for more than 15 days after production. 8. Ketenone preparations may precipitate at temperatures below zero degrees Celsius, and the precipitation will disappear when the temperature rises. 9. Brassica napus is sensitive to enoxanone at bolting and comer-setting stages. The application of enoxanone after rapeseed enters the reproductive growth stage will cause albinism of the rapeseed, leading to no seed-setting of the rapeseed.
