Abamectin, beta-cypermethrin, and emamectin are the most commonly used pesticides in our cultivation, but do you really understand their real properties?
Abamectin is an old pesticide. It has been on the market for more than 30 years. Why is it still prosperous now?
1. Insecticide principle:
Abamectin has strong penetrability and mainly plays the role of contact killing and stomach killing of pests. When we spray the crops, the pesticides will quickly penetrate into the plant mesophyll, and then form poison sacs. The pests will have poisoning reactions when they suck the leaves or come into contact with abamectin during activities, and they will not die immediately after being poisoned. , there will be paralysis, decreased mobility, unable to eat, and usually die within 2 days. Abamectin has no ovicidal effect.
2. Main pest control:
Application of abamectin on fruits and vegetables: can kill mites, red spiders, rust spiders, spider mites, gall mites, leaf rollers, diploid borers, diamondback moth, cotton bollworm, green worm, beet armyworm, aphids, leaf miners , Psyllids and other pests have a very good effect. At present, it is mainly used for rice, fruit trees, vegetables, peanuts, cotton and other crops.
1. Insecticide principle:
Non-systemic insecticides, but insecticides with contact and stomach poisoning effects, destroy the function of the nervous system of insects by interacting with sodium channels.
2. Main pest control:
Beta-cypermethrin is a broad-spectrum insecticide with high insecticidal activity against many kinds of pests. There are: tobacco caterpillars, cotton bollworms, red bollworms, aphids, leafminers, beetles, stink bugs, psyllids, carnivores, leaf rollers, caterpillars, and many other pests have good effects.
1. Insecticide principle:
Compared with abamectin, emamectin has higher insecticidal activity. Acitretin can enhance the effect of nerves such as amino acid and γ-aminobutyric acid, so that a large amount of chloride ions enter nerve cells, causing loss of cell function, disrupting nerve conduction, and larvae stop eating immediately upon contact, resulting in irreversible paralysis. Died within 4 days. The insecticide is too slow. For crops with a large number of pests, it is recommended to speed up and use them together.
2. Main pest control:
It is widely used in vegetables, fruit trees, cotton and other crops, and has the highest activity against mites, Lepidoptera, Coleoptera and pests. It has the unparalleled activity of other pesticides, especially for the red-banded leaf roller, tobacco budworm, tobacco hawkmoth, diamondback moth, dryland armyworm, cotton bollworm, potato beetle, cabbage meal borer and other pests.
When choosing products, you must know more and then choose according to your own situation, so as to achieve a more efficient way of killing insects.
