Imidacloprid, an insecticide belonging to the neonicotinoid class. Imidacloprid is a very effective insecticide with a new structure. The selection of imidacloprid will have the following characteristics. The Chinese pesticide net Xiaobian will introduce you specifically:
In metal cutting, hole processing is the most common process. In hole processing, drill drilling is the basic process.
When drilling, if the hole on the workpiece is very deep, carbide deep hole drills should be used at this time.
Specially used for processing deep hole drills, deep hole drills. In processing, holes with an aperture ratio greater than 6 are usually called deep holes. Due to the poor rigidity of the drill rod, it is difficult to remove heat and debris during deep hole drilling, and it is easy to bend and vibrate. Cooling and cooling systems are usually used to solve cooling and chip removal problems. In the automotive, mold and aerospace industries, deep hole drill bits are very popular.

First, the insecticidal ability mechanism of imidacloprid is relatively unique. It is a neurotoxic agent. The efficacy of imidacloprid is directed to the nicotinic acetylcholine receptor of the post-synaptic membrane of the nervous system in the body of the pest. It can block the active nervous system of the pest without abnormal stimulating conduction, so the main performance is pest. The paralysis is lethal. Imidacloprid is different from conventional insecticides, so it is very effective for the insects that are resistant to insecticides such as carbamate and organophosphate. If they are applied to imidacloprid, they can still have a very effective effect. When imidacloprid is mixed with the above types of insecticides or mixed, the effect will be more significant.
Second, it is relatively easy to cause pest resistance. Because the functional sites of imidacloprid are relatively simple, pests can easily become resistant to imidacloprid. When we use it, we need to control the number of times of drug use. It is forbidden to use imidacloprid twice in the same kind of crops. If we It is observed that when the effect of healing in the field is reduced, it is necessary to immediately replace the organic phosphorus or other kinds of insecticides .
Third, imidacloprid has broad-spectrum, high-efficiency and long-lasting performance. The use of imidacloprid has been distributed to more than 60 types of crops in more than 80 countries around the world, and it is listed as the highest-selling insecticide in the world along with chlorpyrifos. Imidacloprid has a good effect on pests such as aphids and sucking mouthparts, as well as coleoptera-type pests. Usually, about 1 to 2 grams of active ingredient per acre can be used to obtain good control. The effect, and its efficacy period will reach several weeks, if the pesticide is used once, some crops can be protected from pests throughout the process.
Fourth, imidacloprid is also very suitable for the treatment of soil and seeds, it has stomach poisoning and contact killing effect on pests. After spraying the leaf surface, although the effect of the drug is relatively good, the effective period is also very long, but the agent remaining in the stems and leaves of the crop is always the original structure of imidacloprid. However, we chose to apply imidacloprid to soil and seed treatment because it has better systemic properties. After being absorbed by the roots of plants and entering the body of the crop, the metabolites will have higher insecticidal activity, which is based on imidacloprid. The original body and the metabolites of the crop together achieve the insecticidal effect, so its control effect will be better. At the time of seed treatment, we were also able to apply a mixture of imidacloprid and a bactericide together.
