The role of imidacloprid:
Imidacloprid is a nitromethylene systemic insecticide and acts on the nicotinic acetylcholine receptor. It interferes with the motor nervous system of pests and causes chemical signal transmission to fail. There is no cross-resistance problem. For the control of piercing-sucking pests and their resistant strains. Imidacloprid is a new generation of chlorinated nicotine insecticides with broad-spectrum, high efficiency, low toxicity, and low residues. It is not easy for pests to develop resistance, and has multiple effects of contact killing, stomach toxicity and systemic inhalation [1]. When pests come into contact with pesticides, the normal conduction of the central nervous system is blocked, causing them to paralyze and die. The quick-acting effect is good, and the control effect is high one day after the drug, and the residual period is about 25 days. There is a positive correlation between the efficacy and temperature, the higher the temperature, the better the insecticidal effect. Mainly used to control piercing-sucking pests.
How to use Imidacloprid:
Mainly used to control piercing-sucking mouthpart pests (can be used alternately with acetamiprid at low and high temperature -- imidacloprid for high temperature, acetamiprid for low temperature), such as aphids, planthoppers, whiteflies, leafhoppers, thrips ; It is also effective for some pests of Coleoptera, Diptera and Lepidoptera, such as rice weevil, rice worm, leaf miner, etc. But it is not effective against nematodes and red spiders.
It can be used for crops such as rice, wheat, corn, cotton, potatoes, vegetables, sugar beets, and fruit trees. Due to its excellent systemic properties, it is especially suitable for seed treatment and granule application. Generally, 3 to 10 grams of active ingredients are used for mu, sprayed with water or seed dressing. The safety interval is 20 days. Pay attention to protection when applying the medicine, prevent contact with the skin and inhalation of the powder and liquid medicine, and wash the exposed parts with clean water in time after the application. Do not mix with alkaline pesticides. It is not advisable to spray in strong sunlight, so as not to reduce the efficacy.
To prevent and control Meadowsweet aphid, apple scab aphid, green peach aphid, pear psyllid, leaf roller moth, whitefly, leafminer and other pests, it can be sprayed with 10% imidacloprid 4,000-6,000 times, or 5% imidacloprid EC at 2,000-3,000 times. . Control cockroaches: You can choose Shennong 2.1% cockroach bait.
Seed treatment usage (take 600g/L/48% suspending agent/suspending seed coating as an example)
Can be combined with another sucking mouthpart insecticide (acetamiprid)
<1>: Large-grain crops
1. Peanuts: 40ml of water and 100-150ml of water to coat 30-40 catties of seeds (1 mu of land seeds). .
2. Corn: 40ml of water, 100-150ml of water to coat 10-16 catties of seeds (2-3 acres of seeds).
3. Wheat: 40 ml of water with 300-400 ml of coated 30-40 jin seeds (1 mu of land seeds).
4. Soybeans: 40ml of water and 20-30ml of water to coat 8-12 jins of seeds (1 mu of land seeds).
5. Cotton: 10 ml of water and 50 ml of coated 3 catties of seeds (1 mu of land seeds)
6. Other beans: 40 ml of peas, cowpeas, kidney beans, green beans, etc., and 20-50 ml of water to coat the seeds of one mu of land.
7. Rice: Soak the seeds with 10 ml per acre, and sow after the whitening, and try to control the amount of water.
<2>: Small-grain crops
Coat 2-3 catties of rapeseed, sesame, rapeseed, etc. with 40 ml of water and 10-20 ml of water.
<3>: Underground fruit, tuber crops
Potatoes, ginger, garlic, yam, etc. are generally coated with 40 ml of water and 3-4 catties of water to coat 1 mu of seeds.
<4>: Transplanted crops
Sweet potato, tobacco and celery, onion, cucumber, tomato, pepper and other vegetable crops
Instructions:
1. Transplanted with nutrient soil
40ml, mix 30kg of crushed soil and mix well with nutrient soil.
2. Transplanted without nutrient soil
40 ml of water is the standard to overflow the roots of the crops. Soak for 2-4 hours before transplanting, then mix with the remaining water and crushed soil to form a thin mud, and then dip the roots for transplanting.
