Imidacloprid can control piercing-sucking pests such as aphids, thrips, leafhoppers, whiteflies, and planthoppers. It can also control some pests of the Coleoptera, Diptera, and Lepidoptera orders, but it cannot control nematodes and spider mites.
Effects: It interferes with the motor nervous system of pests, disrupting chemical signal transmission. After contact with the pesticide, the normal conduction of the central nervous system is blocked, ultimately leading to paralysis and death.
Applications
1. Imidacloprid can kill piercing-sucking pests such as aphids, planthoppers, whiteflies, leafhoppers, and thrips, as well as Coleoptera, Diptera, and Lepidoptera pests, such as leaf miners, rice weevils, and rice leaf beetles.
2. Imidacloprid is a new generation of chloronicotine insecticide with broad-spectrum, high-efficiency, low-toxicity, and low-residue characteristics. It also has multiple effects including contact, stomach poison, and systemic action, and pests are unlikely to develop resistance after use.
Effects
1. Imidacloprid is a nitromethylene systemic insecticide (acting on nicotinic acetylcholine receptors). It interferes with the motor nervous system of pests, disrupting chemical signal transmission, and does not cause cross-resistance.
2. After contact with the pesticide, the normal conduction of the central nervous system is blocked, ultimately leading to paralysis and death.
3. Imidacloprid is ineffective against nematodes and spider mites.
Speed of Action
1. It begins to take effect approximately 10 minutes after application (when mixed with pyrethroid insecticides, it can kill aphids within 3-5 minutes). High control efficacy is achieved after 24 hours.
2. Imidacloprid is more effective at temperatures above 23-26℃, and its effectiveness is slower below 10℃.
3. On sunny, windless days, application can be done around 10 AM or 3-4 PM, when there is no dew in the field, preventing dilution of the pesticide.
Application Methods of Imidacloprid
Wheat Aphids
1. Before sowing, treat seeds with 60-70 grams of imidacloprid suspension seed dressing agent (600 g/L) per 10 kg of seeds.
2. From the heading stage to the early grain-filling stage, apply 4-7 grams of 70% imidacloprid water-dispersible granules per mu (667 square meters) diluted in 30-45 kg of water for even spraying, repeating 1-2 times.
Fruit and Vegetable Pests
To control aphids, whiteflies, thrips, leaf miners, and other pests on cucumbers, eggplants, tomatoes, watermelons, and other fruit and vegetable crops, apply 12-16 grams of 25% imidacloprid wettable powder per mu diluted in 45-60 kg of water for even spraying at the initial stage of infestation, once every 15 days, repeating 2 times.
Cruciferous Vegetable Pests
To control aphids, leafhoppers, and whiteflies, apply 15-20 grams of 10% imidacloprid wettable powder per acre diluted in 30-45 kg of water as a uniform spray at the initial stage of infestation. Repeat every 15 days for two consecutive applications.
Protected Cultivation Pests
To control whiteflies and leaf miners on vegetables in protected cultivation, apply 6-8 grams of 70% imidacloprid water-dispersible granules per acre diluted in 45-60 kg of water as a uniform spray at the initial stage of infestation. Repeat every 10-15 days for 2-3 consecutive applications.
Tea tree green leafhopper
At the initial stage of infestation (or when the number of insects begins to increase rapidly), spray evenly with a 3000-4000 times dilution of 25% imidacloprid wettable powder, or a 600-800 times dilution of 5% imidacloprid emulsifiable concentrate, or a 1200-1500 times dilution of 10% imidacloprid wettable powder, or a 4000-6000 times dilution of 350 g/L imidacloprid suspension concentrate, or a 2500-3000 times dilution of 200 g/L imidacloprid soluble concentrate, or a 6000-8000 times dilution of 50% imidacloprid wettable powder. Spray once every 10-15 days, for 2-3 consecutive applications.
