The magic of deltamethrin insecticide
As a well-established pyrethroid deltamethrin insecticide. When promoting deltamethrin, agricultural technicians often take out a lighter and put a drop of deltamethrin solution on it. Then, you can hear the sound of lighter gas leaking out.
Both terminal agricultural supplies stores and farmers, the end users of agricultural supplies, have developed a strong interest in such “magic”.
According to agricultural technicians, when the chemical liquid dripped on the surface of the lighter. The faster the gas leaks out, the better the quality of the deltamethrin. As a synergist, the insecticidal effect will be more ideal.
The reason why agricultural technicians go to great lengths to do “magic” for customers. Its purpose is to prove to customers the super penetration ability of its own deltamethrin.
Especially for resistant noctuid pests. When the control effect of emamectin and indoxacarb is not satisfactory, add a 4 ml bottle of deltamethrin. It often plays the role of penetrating the waxy cortex of pests, thereby fully exerting its role as a pesticide synergist.
It can be seen that deltamethrin’s good penetration ability and its own insecticidal effect are characteristics that other insecticide synergists do not have.
The insecticidal effect of deltamethrin insecticide
Deltamethrin is one of many pyrethroid products. It is a pesticide that emerged in the 1980s. It has contact and stomach poisoning effects and has strong penetrating ability.
Its site of action is the insect nervous system and it is a nerve agent. After pesticide application, the pests may become over-excited and eventually become paralyzed and die. It also has certain repelling and hunger-eating effects on pests. It is not only effective on adult insects, but also has a certain killing effect on eggs. Therefore, choosing to apply pesticides during the egg hatching period or the young instar stage will achieve the ideal effect of long-lasting insect control.
Two major drawbacks of deltamethrin
Deltamethrin insecticide performs better at low temperatures. Exceeding 30℃ will not only reduce the insecticidal effect, but also increase the toxicity. This increases the risk of crops being harmed by pesticides, which is why although deltamethrin has ideal insecticidal effects and is relatively cheap. With the continuous emergence of new pesticides, the main reason why farmers are reluctant to continue using deltamethrin.
Not only does deltamethrin not have the effect of killing mites, but it can also induce the proliferation of harmful mites. It should be used with caution, especially on crops prone to mites.
①Deltamethrin is used as a pesticide synergist. Only 4 ml per barrel of water (30 catties) can achieve ideal control effects. At this dose, the pesticide can be even in high-temperature weather exceeding 30°C. , and will not increase the risk of drug injury.
②Nowadays, in the mainstream sales market of deltamethrin, in addition to insecticide synergists, the target consumer group is mainly for farmers who grow sporadic vegetables, flowers or fruit trees. 4 ml of deltamethrin + 10 grams of imidacloprid or thiamethoxam, mixed with water Dilute with 10-30 pounds of water and spray to control common pests such as cabbage caterpillars, aphids, whiteflies, ants, crickets, cutworms and underground pests.
③2.5% deltamethrin suspension is to prevent and control sanitary pests. On the ground or wall at a dosage of 1 ml/square meter. It has a good control effect on mosquitoes, flies, ants and cockroaches.
④ Use 0.006% deltamethrin powder to control stored grain pests. The pesticide can be according to the ratio of 0.3-0.5 grams of preparation/1000 grams of raw grain.
