Mentioning acetamiprid and imidacloprid is unheard of than many farmers' friends. Both acetamiprid and imidacloprid are spectral insecticides , and their functions are very similar. So what is the difference between them? Let's follow the Xiaobian to understand it.
I. acetamiprid
Basic Information:
Acetamiprid is a new broad-spectrum insecticide with a certain acaricidal activity, which acts as a systemic insecticide for soil and foliage. It is widely used in the control of rice, especially vegetables, fruit trees, tea aphids, planthoppers, thrips, and some lepidopteran pests.
Application method:
At a concentration of 50-100mg/L, it can effectively control cotton aphid, rapeseed meal, peach heartworm, etc., and can be used to control light moth, orange moth, and pear small heartworm at a concentration of 500mg/L, and can kill eggs. .
The acetamiprid is mainly used to control pests by spraying, and the specific use amount or the amount of the drug varies depending on the content of the preparation. On fruit trees and high-stalk crops, 3% to 2,000 times of preparations are used, or 5% of preparations are 2,500 to 3,000 times, or 10% of preparations are 5,000 to 6,000 times, or 20%. Preparation of 10000 ~ 12000 times liquid or 40% water dispersible granules 20,000 ~ 25,000 times liquid, or 50% water dispersible granules 25000 ~ 30,000 times liquid, or 70% water dispersible granules 35 000 ~ 40 000 times liquid , even spray; in dwarf crops such as grain, cotton, oil and vegetables, generally use 1.5 to 2 grams of active ingredient per 667 square meters, spray 30 to 60 liters of water. Uniform and thoughtful spraying can improve the control effect of the drug. Author: items acres
The main purpose
1. Chlorinated nicotine insecticides. The medicament has the characteristics of wide insecticidal spectrum, high activity, small dosage, long-lasting effect and quick effect, and has the functions of contact and stomach toxicity, and has excellent systemic activity. Hemiptera (Aphids, leafhoppers, whiteflies, aphids, scale insects, etc.), Lepidoptera (Plutella xylostella, L. moth, P. sylvestris, P. sylvestris), Coleoptera (Echinochloa, Corydalis) And the total wingworm pests (thuma) are effective. Since the mechanism of action of acetamiprid is different from that of currently used insecticides, it has special effects on pests resistant to organophosphorus, carbamates and pyrethroids.
2. It is efficient for Hemiptera and Lepidoptera pests.
3. It is the same series as imidacloprid, but its insecticidal spectrum is wider than that of imidacloprid, and it has good control effect on aphids on cucumber, apple, citrus and tobacco. Due to the unique mechanism of action of acetamiprid, it has a good effect on pests that are resistant to pesticides such as organophosphorus, carbamate, and pyrethroids.
2. Imidacloprid
1. Basic introduction
Imidacloprid is a high-efficiency insecticide of nicotine. It has broad-spectrum, high-efficiency, low toxicity, low residue, pests are not easy to produce resistance, and it is safe for humans, animals, plants and natural enemies. It has contact, stomach poison and systemic absorption. Wait for multiple effects. After the pests are exposed to the agent, the normal conduction of the central nervous system is blocked, causing paralysis to die. The product has good quick-acting effect, and has high control effect 1 day after the medicine, and the residual period is as long as about 25 days. The drug effect and temperature are positively correlated, the temperature is high, and the insecticidal effect is good. Mainly used to control sucking mouthparts pests.
1. Characteristics of action
Imidacloprid is a nitromethylene-based systemic insecticide and acts as a acetylcholinesterase receptor for nicotinic acid. It interferes with the insect's motor nervous system and causes chemical signal transmission to fail, without cross-resistance. It is used to control sucking mouthparts pests and their resistant strains. Imidacloprid is a new generation of chlorinated nicotine insecticide with broad spectrum, high efficiency, low toxicity, low residue, pests are not easy to produce resistance, safe for humans, animals, plants and natural enemies, and has contact, stomach poison and systemic absorption. Multiple pharmacological effects. After the pests are exposed to the agent, the normal conduction of the central nervous system is blocked, causing paralysis to die. It has good quick-acting effect, and it has high control effect 1 day after the drug, and the residual period is up to 25 days. The drug effect and temperature are positively correlated, the temperature is high, and the insecticidal effect is good. Mainly used to control sucking mouthparts pests.
2. How to use
It is mainly used for the prevention and control of sucking mouthparts pests (can be used with low-temperature rotation of acetamiprid - low temperature with imidacloprid, high temperature with acetamiprid), prevention and control such as mites, locusts, whiteflies, leafhoppers, hummers Certain pests of Coleoptera, Diptera and Lepidoptera, such as rice weevil, rice negative worm, and leaf miner are also effective. But not effective against nematodes and red spiders. Can be used in rice, wheat, corn, cotton, potatoes, vegetables, beets, fruit trees and other crops. Due to its excellent systemic properties, it is particularly suitable for application by seed treatment and granulation. Generally, the active ingredient is 3~10 grams, sprayed with water or seeded. The safety interval is 20 days. Pay attention to the protection when applying the medicine, prevent contact with the skin and inhaled powder, liquid medicine, and wash the exposed parts with water in time. Do not mix with alkaline pesticides. It is not advisable to spray under strong sunlight to avoid reducing the efficacy.
Control pests such as Spiraea japonica, apple mites, peach aphid, pear hibiscus, leaf roller moth, whitefly, and leafminer, spray with 10% imidacloprid 4000-6000 times, or spray with 5% imidacloprid EC 2000-3000 times . Prevention and control: You can choose Shennong 2.1% cockroach gel bait.
The continuous use in recent years has caused high resistance and has been banned in countries on rice.
