Avermectin set sterilization, insecticide, mite killing, nematode in one, in many types of pesticides, is definitely a star-like existence, the common content is mainly 1.8%, 2%, 3%, 5%, 10%, dosage forms are emulsion, suspension, microcapsule suspension, microemulsion, as well as 0.5% and 1% granules.
It is only with the continuous emergence of new pesticides that avermectin, which is known as the "shoulder handle" of the pesticide industry, is now gradually fading in people's vision, which is caused by the new and tired of the old by agricultural people, or is the distribution of avermectin without profit? Is it that crops develop resistance, or do farmers not know how to use avermectin scientifically?
The reason why avermectin has lost its ability to dominate the market, but it still plays a pivotal role in the control of pesticide pests, and has an extremely superior control effect in the control of phylloxera, mite control (red spider, tea mite), lepidoptera pest control (cotton bollworm, cabbage moth, beet noctus, twill moth, etc.), hemiptera pest control (whitefly, tea leafhopper, aphid), dipteran pest control (spotted fly), tamarind pest control (thrips) and root-knot nematodes.
In the pesticide industry, how many similar products can there be such a wide spectrum of avermectin to control pests, and the effect is still quite superior?
The insecticidal mechanism of avermectin is to interfere with the neurophysiological activities of pests, stimulate the release of y-aminobutyric acid, and this component has an inhibitory effect on the nerve conduction of pests, and plays a role in stomach poisoning and contact killing of pests, after administration, pests appear paralyzing symptoms, inactivity does not eat, about 3 days before gradually dying, so the insecticidal speed of avermectin is slower, and does not have the effect of killing eggs.
In order to solve this problem, compounding avermectin with insecticides with fast-acting insecticides and insecticides with egg killing function is the best way to solve the shortcomings of avermectin.
Since the advent of avermectin in China in the 80s, the end of the 90s has become the "shoulder handle" of the pesticide industry, and firmly occupies half of the pesticide market, and it is precisely because of the wide application of avermectin, as well as uncontrolled use, avermectin resistance has also been strengthened, as an old product, profits have become transparent, agricultural management department has also lost the motivation to continue to promote, therefore, avermectin has been gradually surpassed by the new forces, and eventually reduced to chicken ribs.
But we should not ignore the power of avermectin, once farmers and friends master the use of skills, learn to mix scientifically, avermectin is still full of lethality.
Share some insecticidal formulas mixed with avermectin that have a significant synergy:
First, the common formula for the control of small insects - aphids, whiteflies, thrips, tea small green leafhoppers, rice planthoppers, etc
Avermectin + acetamiprid, avermectin + imidacloprid, avermectin + furazine, avermectin + thiamethoxine and so on.
Taking the control of aphids as an example, the single-dose control effect of avermectin is not ideal, but after mixing with nicotinic insecticides, the insecticidal effect can be infinitely improved, and farmers can buy pesticide production enterprises mixed products in agricultural material stores, or they can buy two pesticide single products for mixing.
In general, the price of their own mixing is low, because whether it is avermectin or acetamidine, imidacloprid and other nicotinic insecticide single agent, the price tends to be transparent, for agricultural material stores, are small profit products, once the farmers have mastered the mixing skills, they can achieve the ultimate goal of costing less and efficient pest control.
Second, the common formula for the control of Lepidoptera pests - cotton bollworm, small cabbage moth, beet nocturnal moth, twill nocturnal moth, corn borer, etc
Avermectin + cypermethrin, avermectin + chlorhexenamide, avermectin + chlorpyrifos, avermectin + indinalevir, avermectin + fluolamide, avermectin + insecticidal list, etc.
Third, the common formula for the control of mite pests - red spider, tea yellow mite, etc
Avermectin + pyridoxine (this formula has a "long history", similar to avermectin itself, now more resistant, but the price is also cheaper, it is recommended to use in the early stage of the occurrence of pest mites), avermectin + bifenumerate, avermectin + tetramethazine, avermectin + spironate (killing mites and eggs, the duration of validity is more than 30 days), avermectin + ethanazole (the duration of validity is more than 30 days).
Fourth, the control of leafminer fly synergistic formula
Avermectin + fly-killing amine
Fifth, the control of root-knot nematode synergistic formula
Prevention of 0.5% or 1% avermectin granules field application or ditch application, treatment with avermectin + thiazoliphos for mixing, the effect is more significant, crop growth period nematode harm, you can take a high content of avermectin dilution after irrigation roots.
