How to use imidacloprid? Keep this usage guide handy
Imidacloprid is a nitromethylene systemic insecticide and an agonist at the nicotinic acetylcholine receptor; it disrupts the insect's motor nervous system so that chemical signal transmission fails, and there is no cross-resistance problem.
It is mainly used to control piercing-sucking mouthpart pests such as aphids, thrips and whiteflies, and it also gives good control of some pests in the Lepidoptera and Diptera, such as leafminer flies, leaf-mining moths, striped flea beetles and seed maggots.
It is suitable for crops such as vegetables, tobacco and fruit trees.
The pre-harvest interval is 20 days.
Imidacloprid has the characteristics of a broad spectrum, high efficiency, low toxicity and low residue; pests do not easily develop resistance to it, and it is safe to humans, livestock, plants and natural enemies. It also has multiple modes of action - contact, stomach and systemic - with a long residual effect, no resistance problems, low toxicity to beneficial insects and safety to the environment, making it the first choice for pollution-free production.
After pests come into contact with the chemical, normal conduction in the central nervous system is blocked, causing paralysis and death.
It has good quick-acting performance: one day after application there is already relatively high control efficacy, and the residual period lasts about 25 days.
Its efficacy is positively correlated with temperature; the higher the temperature, the better the insecticidal effect.
It is mainly used to control piercing-sucking mouthpart pests, such as aphids.
How to use:
Main contents and formulations: 5% emulsifiable concentrate, 5% tablets, 10% wettable powder, 25% wettable powder, 50% wettable powder, 70% wettable powder, 70% water-dispersible granules, 200 g/L soluble concentrate, 350 g/L suspension concentrate, 600 g/L suspension concentrate for seed coating, 70% slurry seed treatment, etc.
Imidacloprid is mainly used to control piercing-sucking mouthpart pests, such as aphids, planthoppers, whiteflies, leafhoppers and thrips; it is also effective against certain pests of the Coleoptera, Diptera and Lepidoptera, such as rice weevils, rice leaf beetles, rice stem borers and leaf-mining moths. However, it is ineffective against nematodes and red spider mites.
Imidacloprid can be used on crops such as rice, wheat, corn, cotton, potato, vegetables, sugar beet and fruit trees. Because of its excellent systemic property, it is particularly suitable for application as seed treatment and by broadcasting granules. Generally, 3-10 grams of active ingredient is used per mu, diluted with water for spraying or for seed dressing. The pre-harvest interval is 20 days.
Take protective measures when applying: prevent contact with the skin and inhalation of the powder or liquid, and after application promptly wash exposed areas with clean water. Do not mix with alkaline pesticides. Do not spray under strong sunlight, so as not to reduce efficacy.
To control pests such as spirea aphid, apple aphid, green peach aphid, pear psylla, leaf-rolling moths, whiteflies and serpentine leafminers, spray with a 10% imidacloprid solution diluted 4000-6000 times, or with a 5% imidacloprid emulsifiable concentrate diluted 2000-3000 times. To control cockroaches, Shennong 2.1% cockroach gel bait can be chosen.
Because imidacloprid has been used continuously in recent years, it has caused very high resistance, and its use on rice has already been banned by the state.
Precautions:
1. This product must not be mixed with alkaline pesticides or substances.
2. During use, do not contaminate beekeeping or silkworm-rearing sites or related water sources.
3. Apply at the appropriate time; do not apply within one week before harvest.
4. If accidentally ingested, induce vomiting immediately and send the person to hospital for treatment promptly.
5. Take protective measures when applying: prevent contact with the skin and inhalation of the powder or liquid, and after application promptly wash exposed areas with clean water. Do not spray under strong sunlight, so as not to reduce efficacy.
