These four insecticides, insecticidal effect of a more than a powerful, which you think is better

The development of pesticides with broad control spectrum, good quick-acting, long lasting effect and low toxicity is the most effective measure to improve the effectiveness of pesticide control and reduce the number of pesticide spraying.SWAN insect killer supplier Today I would like to introduce you to four newly developed pesticides which are the most effective pesticides at present. How do you choose between them?

1. Flufenacet

Flufenacet, also known as Cyanamid, is made by changing various polar groups on the benzene ring, and is more broad-spectrum than Chlorfenapyr, with higher efficiency and a wider range of applicable crops. It also controls pests by activating the fisetin receptor of the target pest. Activation of fisetin receptor releases calcium ions stored in rhabdomyosin and smooth muscle cells, leading to disruption of muscle movement regulation, paralysis, and eventual death of the pest. It is so safe for the environment that the U.S. Environmental Protection Agency has registered it as a "low risk" pesticide.SPRITEX insect killer manufacturer Deltamethrin is considered the perfect complement to chlorpyrifos.

Flufenacet can have strong permeability and systemic conductivity, mainly touch and stomach toxicity research, almost all of our lepidopteran pests have a very good activity, the adult and larval stages have their own excellent activity,Chinese RAMBO Insecticide spray the action of the analysis of the speed of fast, the pests 1-2 hours to stop the learning activities, about 3-5 days, to reach the peak of the dead bugs, the holding period of up to 20 days. The effect period is up to 20 days. Especially for rice stem borer and leaf roller effect is also very important and prominent. However, due to the fluorine contained in flufenacet, afraid of meeting the fate of fipronil, it has not been registered in rice, only used in vegetable registration system, the pricing risk is higher, which limits the promotion and use of flufenacet, although the company develops earlier, the problem of the use amount and area of promotion and application does not need to be particularly large.

2. Chlorfenapyr

Benzamide is based on fipronil, which activates fish nicotine (muscle) receptors in insects. It causes excessive release of calcium ions from the cells, which eventually paralyzes the insect and kills it.

Bromoxynil mainly has touch toxicity and gastric toxicity, with wide insecticidal spectrum, high activity, endosorption conduction, long persistence period, and not easy to produce resistance, especially to the larvae of lepidopteran pests. Generally, the pest stops its activity after feeding for 3-5 hours and reaches the peak of insect death in 5-7 days. According to the current test results, the activity of Chlorfenapyr on target pests is 10 ~ 100 times higher than other products, and it has good control effect on Lepidoptera, such as Noctuidae, Moths, Moths, Sticky Moths, Vegetable Moths, Lepidoptera, Lepidoptera, Moths, and many others. Many kinds of non-Lepidoptera pests, such as Diptera, Diptera and Diptera. Safe for crops, low toxicity to humans, animals, bees, fish, shrimp and other environmental insects. Because the patent period has expired, the price has been greatly reduced. It is the most widely used pesticide at present. However, some areas due to years of use of a single preparation, resistance has appeared, the prevention and control effect is gradually declining, but compared with other insecticides, the insecticidal effect is still very prominent.

3. Cyhalothrin

Bromocyanamide, also known as cyanamide, is made by changing various polar groups on the benzene ring. They have a wider spectrum and are more efficient than benzamide and are used on a wider range of crops. It also controls pests by activating fish nicotinic receptors in target insects. Activation of fish nicotinic receptors releases calcium ions stored in rhabdomyosin and smooth muscle cells, leading to disturbed muscle movement regulation, paralysis and death. It is so safe that it is considered a "low risk" pesticide by the U.S. Environmental Protection Agency. Bromoxynil is considered the perfect complement to chlorpyrifos.

Bromoxynil is also highly penetrating and systemically conductive, making it the first multi-spectrum insecticide to control both chewing and sucking mouthparts, as well as stinging, filing and sucking mouthparts. It is effective not only against lepidopteran pests such as heart-eaters, squash moths, cotton bollworms, beet nightshade moths and cabbage greenfly, but also against tobacco fly, whitefly, stem borer, thrips, aphids, American spotted fly, hemipteran and dipteran pests. It also provides excellent control. It knocks down pests in minutes and prevents them from spreading viruses.

Clothianidin products can be widely used in a wide range of cash crops such as fruits and vegetables, cucurbits, brassicas, leafy vegetables, bulb vegetables, potatoes, citrus, coffee trees, nuts, drupes, nuts, fruits of the tropics, cotton, soybeans, olives, tea trees, tobacco and rice.

4. Tetrachlorvinphos

Tetrachlorfenapyr is structurally modified by modifying the benzene ring substituent and pyrazole substituent in its structure. By combining with the fisetin receptor in the pest, it opens the calcium channel, so that the calcium ions stored in the cells are continuously released into the muscle plasma, and the calcium ions combine with the matrix protein in the plasma to cause continuous muscle contraction. Insect body symptoms manifested as convulsions, refusal to feed, and eventually death.

Tetrachloramid is a highly efficient and low toxicity pesticide with high activity against lepidopteran pests, low toxicity to mammals and safe for non-target organisms such as bees and birds. Tetrachloroamino benzamide is highly penetrating and its main effects are contact and stomach poisoning. It has ultra-high activity against Lepidoptera, good fast-acting and long persistence period. It is mainly used for the control of lepidopteran pests such as stem borer and leaf borer on rice, as well as cabbage moth and cabbage greenfly on vegetables, etc. The holding period is about 17 days. It is less active against beet moth and corn borer.

The above four insecticides are all diamine insecticides, and their mode of action is basically the same. They are characterized by wide insecticidal spectrum, long duration of efficacy and low toxicity. The focus of insecticidal activity is slightly different from each other, and it is not possible to determine which one is better; according to the object of control, choose the appropriate product in order to achieve the expected control effect.
