Imidacloprid is an insecticide. Many people are not very familiar with the extensive use of agriculture. So today, Xiaobian will explain to you what is the use of imidacloprid and imidacloprid.

First, the active ingredient of imidacloprid

1Commodity name: Imidacloprid, Aimeil, rehabilitation, great heroes, great harvest, clean, one-time net, sputum, high-tech, streak, Brin, drug lord, 蚜克西, 蚜虫灵,虱蚜灵, enemy, anti-King, etc.

2 main content and dosage form: 5% emulsifiable concentrate, 5% tablet, 10% wettable powder, 25% wettable powder, 50% wettable powder, 70% wettable powder, 70% water-dispersible granules, 200 g / Liter solution, 350 g / liter suspension, 600 g / liter suspension seed coating, 70% wet seed dressing, etc.

3 Physicochemical properties: pure imidacloprid is white crystal melting point 143.8 ° C (crystal I), 136.4 ° C (crystal II) slightly soluble in water, toluene, isopropanol soluble in dichloromethane pH 5 ~ 11 stable. The original drug is shallow Orange crystal. High stability in soil. Half-life is 150 days. It is a low-toxic insecticide. The acute oral LDso of rats is 1260 mg/kg. It is slightly irritating to rabbit eyes. Carcinogenic and mutagenic effects are low toxicity to higher animals, fish and birds.

4 Product Features: Imidacloprid is a pyridine insecticide with systemic, stomach, contact, antifeedant and repellent effects. It has a wide spectrum of insecticides, high efficacy, long duration, and low residue. Its insecticidal mechanism is a function. Insect nicotinic acid acetylcholinesterase receptor interferes with the insect motility nervous system. After the pest is exposed to the agent, the normal conduction of the central nervous system is blocked and paralyzed to death. The drug has good quick-acting effect and has high efficacy and drug 1 day after application. The effect and temperature are positively correlated with high temperature and good insecticidal effect.

5 imidacloprid often with insecticidal, insecticidal bis, buprofezin, triazolyl, triazophos, isoprocarb, anti-Sui Wei, Zhong Dingwei, butyl thiocarbamate, methomyl, dichlorvos, chlorpyrifos, Malathion, phoxim, beta-cypermethrin, cypermethrin, bifenthrin.

5. Insecticides such as fenvalerate, avermectin, chlorpyrifos, and chlorpyrifos are compounded to produce compound insecticides.

6 Applicable crops and control objects: Imidacloprid is widely used in melons and vegetables, grain and cotton oil crops, beets, tea trees, potatoes, deciduous fruit trees, evergreen fruit trees and ornamental plants. It has good control effects on sucking mouthparts pests such as aphids. Classes, leaf mites, white mites, planthoppers, hummers, hibiscus, scorpion, etc., and also have good insects such as the coleoptera, the genus Diptera, and the Lepidoptera. It can also be used as a sanitary insecticide and termiticide.

Second, the main application of imidacloprid

Imidacloprid is mainly used to control sucking mouthparts pests such as aphids, planthoppers, whiteflies, spider mites and thrips; some pests of coleoptera, diptera and lepidoptera, such as rice weevil, rice negative worm, Rice borers, leaf miners, etc. are also effective. But they are not effective against nematodes and red spiders. They can be used in rice, wheat, corn, cotton, potato, vegetables, beets, fruit trees and other crops.

Third, imidacloprid for crops

1 Cruciferous vegetable aphids, leafhoppers, whiteflies, etc., from the beginning of pests or when the amount of insects begins to rise rapidly, spray spraying for about 15 days, once every two times. Use 5% emulsifiable concentrate for every 667 square meters 30-40 ML or 5% tablet 30-40 g or 10% wettable powder 15-20 g or 25% wettable powder 6-8 g or 50% wettable powder 3-4 g or 70% wettable powder or 70% water Dispersible granules 2 ~ 3 grams or 200 grams / liter solution 8 ~ 10 ml or 350 g / liter of suspending agent 4 ~ 6 ml water 30 ~ 45 kg even spray.

2 Tomatoes, eggplants, cucumbers, watermelons and other melons and aphids, whiteflies, thrips, and larvae are sprayed from the early stage of pests or when the number of insects begins to increase rapidly. Generally, every 6 67 square meters use 5% emulsifiable concentrate 60-80 ml or 5% tablet 60-80 g or 10% wettable powder 30-40 g or 2 5% wettable powder 12-16 g or 50% wettability Powder 6-8 grams or 70% wettable powder or 70% water-dispersible granules 4-6 grams or 200 grams/liter solution 15-20 ml or 3 50 g/liter suspension 8-12 ml water 45~ 60 kg uniform spray.

3 Protected vegetables, whitefly, and spotted fly, spray from the initial stage of pests for 10 to 15 days, and spray 2 to 3 times. Generally, use 5% EC 80-100 ml or 5% for every 6 6 7 square meters. 80-100 g or 10% wettable powder 40-60 g or 25% wettable powder 20-25 g or 50% wettable powder 100-12 g or 70% wettable powder or 70% water dispersible granule 6 -8 grams or 200 grams / liter of solution can be 20 ~ 30 ml or 3 50 g / liter of suspending agent 12 ~ 15 ml with water 45 ~ 60 kg even spray.

4 wheat aphids before seeding, seed dressing or coating every 10 kg of seeds using 600 g / liter of suspension seed coating 60 ~ 70 grams or 70% wet seed dressing 50 ~ 60 grams of uniform seed dressing or coating drying and sowing During the growing season, spray 1 to 2 times from the heading stage of wheat to the beginning of filling. Generally, use 5% emulsifiable concentrate of 60-100 ml or 5% of tablets 60-100 g or 10% wettable powder for every 66 7 square meters. 50 g or 25% wettable powder 12-10 g or 50% wettable powder 6-10 g or 70% wettable powder or 70% water dispersible granule 4-7 g or 200 g/L solution 15-25 ML or 350 g / liter of suspending agent 8 ~ 15 ml with water 30 ~ 45 kg evenly sprayed.

5 rice planthoppers and spider mites in the nymphal hatching period until the 3rd instar spraying or tillering stage to the jointing stage average 0.5 to 1 worm per cluster, from the booting to the heading period, the average number of worms per plexus 10, grouting During the milk ripening period, there are insects io~is heads per plexus, and the wax maturity period is 15-20 shots per plexus. Spraying is generally used for 667 square meters of 5% EC 60-80 ml or 5% tablets 60. ～80g or 10% wettable powder 30---.40g or 25% wettable powder 12～16g or 50% wettable powder 6-8g or 70% wettable powder or 70% water-dispersible granule 4 ~ 6 grams or 200 grams / liter of solution 15 ~ 20 ml or 350 grams / liter of suspending agent 8 ~ 12 ml water 30 ~ 45 kg even spray. Spray the drug to the middle and lower parts of the plant.

Use of imidacloprid: Imidacloprid is especially suitable for seed treatment and granule application because of its excellent systemic properties. Generally, the active ingredient is sprayed with 3~10g of water or mixed with water. The safety interval is 20 days. When taking medicine, pay attention to prevent contact with skin and inhaled powder. After using the medicine, it is necessary to wash the exposed parts with water in time. Do not mix with alkaline pesticides . Do not spray under strong sunlight to avoid reducing the effect.
