When it comes to acaricides , many farmers’ friends have heard about it. The acaricides are mainly used to prevent herbicides. At present, there are not too many acaricide products on the market. So which acaricides are better? Let's follow the Xiaobian to understand it.

Acaricide product types and characteristics:

1. Nisolon (thiazinone). The drug has good penetrability to the plant epidermis, but has no systemic conduction. It has strong bactericidal and juvenile characteristics for a variety of plant pests, and is ineffective for adult mites, but has an inhibitory effect on hatching of eggs produced by female adults exposed to the drug solution. The drug is a non-temperature sensitive acaricide, and the effect of using it at high temperature or low temperature is not significantly different, and the residual effect period is long. At present, the active ingredient content on the market is: 5%.

2 acetylene (Keite): It has the effects of contact and stomach toxicity. It is effective against Cheng and Ruo, and has poor egg-killing effect. When the temperature is above 20 °C, the efficacy can be improved. It has phytotoxicity to the young shoots of citrus, and also has phytotoxicity to the sweet orange young fruit. It is easy to cause sunburn at the high temperature, and it will also affect the greening near the umbilicus. Therefore, the concentration should not be increased arbitrarily. Acetylene is one of the varieties that are not easy to develop resistance and have relatively stable drug efficacy in current acaricides.

3, Ling Ling. The preparation is a spectrum, contact killing acaricide, and can be used for controlling various plant diseases. It has a good effect on the whole growth period of the cockroach, that is, the egg, the young cockroach, the ruthenium and the cockroach. The cockroach in the moving period also has obvious quick killing effect. The drug is not affected by temperature changes, and can be used satisfactorily in early spring or autumn. At present, the active ingredients in the market are: 10%, 15% and 20%.

4, avermectin. Abamectin is a natural product isolated from soil microorganisms. It has a contact and stomach toxicity to insects and acarids, and has a weak fumigating effect and no systemic action. However, it has a strong osmotic effect on the leaves, which can kill the pests under the epidermis and has a long residual effect. At present, the active ingredients in the market are: 0.5%, 1%, 1.8%, 2%.

5, triazolium tin: is a strong killing agent, can kill the cockroach and summer eggs, invalid for winter eggs. Triazole tin has phytotoxicity to young shoots. Its efficacy depends on whether the content and suspension rate meet the standard.

6, dicofol: for killing spectrum, high activity, safety to natural enemies and crops. It is a nerve poisoning agent and is effective for both sputum and sputum. The drug is slowly decomposed and there is still a small amount of residue in the year after the drug is administered. At present, the active ingredients in the market are: 10%, 15%, 20%.

7. Tolk: It is a long-acting acaricide based on contact killing. When the temperature is above 22°C, the effect is better. It is strong in killing ability, and it has little lethal effect on the egg. The drug release is slow after spraying. After three days, the activity was enhanced, and the drug release peak was reached four days after the drug. It is safer for natural enemies.

8. Green Ying (enemy kill): It is an oil emulsion processed with white wax oil. It can prevent the spawning and change the physical function of feeding behavior by blocking the stomata, and achieve the control of citrus red spider and citrus. The purpose of other pests. Green Ying can effectively kill Cheng Ruo, but it has no lethal effect on eggs. Note that Green Ginger should not be used during hot and dry seasons.

9, triazole tin. A broad-spectrum acaricide for strong contact. Can kill if full, adult and summer eggs, invalid for winter eggs. It has good stability to light and rain, and has a long residual period. Safe for crops at commonly used concentrations. At present, the active ingredient content on the market is: 5.5%.

10, Qi Ling series of pharmacy: a variety of varieties on the market, more effective in the spring, due to continuous use for many years, the resistance is already very obvious, can be mixed with green Ying, so as to improve control.

Third, the use of acaricide needs to pay attention to three aspects

1. The choice of acaricide should fully consider the four factors of temperature sensitivity, resistance, safety and protection of natural enemies.

2. When the base of the mites is high, it can be mixed with scorpion or insect killing star; in the mildew rain season from June to July, it can be considered to use the strong tin-killing agents such as triazole tin and tork. Wait.

3, the first half of the spring is not the beginning of the summer season, the temperature is lower, citrus is in the tender stage and young fruit period, should choose the temperature is not sensitive, safe, good for natural enemies, such as green Ying.

4. In the second half of the year, the control effect of acetylene is the most fully used, and it can be used interchangeably with organotin.
