Application of imidacloprid in field crops

Imidacloprid is a very commonly used insecticide . It can be used on a variety of field crops such as rice, wheat, corn, cotton, etc., but it has already produced strong resistance on rice. It has been banned in the country. Usually, imidacloprid The safe interval of use is 20 days. This point must be paid attention to by the majority of farmers. Let us know the use of imidacloprid.

The characteristics of imidacloprid

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.

Method of using imidacloprid

First, large crops

1. Peanut: 40 ml of water with 100-150 ml of coated 30-40 kg of seeds (1 mu of seed)...

2. Corn: 40 ml of water with 100-150 ml of coated 10-16 kg seeds (2-3 mu of ground seeds).

3. Wheat: 40 ml of water with 300-400 ml of coated 30-40 kg of seeds (1 mu of ground seeds).

4. Soy: 40 ml of water with 20-30 ml of coated 8-12 kg of seeds (1 mu of ground seeds).

5. Cotton: 10 ml of water, 50 ml of coating, 3 kg of seeds (1 mu of seed)

6. Other beans: peas, cowpeas, kidney beans, green beans, etc. 40 ml of water 20-50 ml coated with one acre of seeds.

7. Rice: Soak seeds in 10 ml per mu, seed after whitening, and try to control the amount of water.

Second, small crops

Rape, sesame, rapeseed, etc., coated with 2-3 kg of seeds with 40 ml of water 10-20 ml.

Third, underground results, tuber crops

Potatoes, ginger, garlic, yam, etc. generally use 40 ml of water to 3-4 kg of water to coat 1 mu of seeds.

Fourth, transplanted crops

Sweet potato, tobacco and celery, onion, cucumber, tomato, pepper and other vegetable crops.

Instructions:

40 ml of water is passed over the roots of the crop. After soaking for 2-4 hours before transplanting, stir the remaining water with the crushed soil to form a thin mud, and then transplant the roots.

Reaction Frame

The function of the reaction frame is to transmit force. Go to the floor and use it to test samples with hydraulic actuators. The size of the reaction frame or part of this frame will be used for most major experiments in the laboratory. Because the geometry of future experiments is unknown, the reaction frame has been designed as a reconfigurable frame that can apply forces at different height levels or vertically from above.
