Hello everyone, I am a farmer. In the autumn, mite pests have gradually increased, bringing a lot of trouble to our farmer friends. At present, there are many types of acaricides on the market, each of which has its own characteristics and methods of use, and only by choosing the right agent can it play a role in eliminating pests. Now is the peak of the citrus red spider pest, today I will introduce you to a kind of effective control of red spiders acaricide - gram mite, let's take a look at it!
Crete, also known as alkyne mite, is a low-toxicity mite. The gram mite sold on the market today is generally in the form of emulsion. Kermat has the effect of touch killing, stomach poisoning, fumigation, can effectively kill mites and mites, but the effect of egg killing is not ideal. There may be farmer friends who are not quite sure what fumigation means. In simple terms, when gram mite is used, it will produce a pungent odor to drive away pests, a bit like we usually order mosquito coils to drive away mosquitoes. In addition, stomach poisoning and internal suction are also not confused. Gastric toxicity means that when you spray the liquid on the leaf, the pest is poisoned after eating the liquid; internal suction is that the leaf has absorbed the liquid, and the pest will be poisoned as long as it sucks the juice of the leaf.

As for the touch killing effect, it is easy to understand, that is, when the pest comes into contact with the crete, it will be poisoned and die. Because Kermat has these many functions, it can be applied to a variety of crops such as apples, peaches, grapes and so on. The most commonly used is to kill red spiders with gram mites, because red spiders are a type of mite pest, and according to research, gram mite resistance is not hereditary. So when kermat is sprayed on the citrus leaves of red spiders, adult mites that come into contact with the liquid will stop eating and lay eggs, and then quickly die within 48 hours.
Before explaining the use of gram mites to control red spiders, we must first know the characteristics of red spiders. If it's the pest that gives citrus growers the most headaches, the red spider definitely ranks in the top three. Red spiders usually occur in spring and autumn and can occur in 15-18 generations throughout the year. It's autumn, and around 20 degrees, there are already red spiders in many citrus orchards. Generally on the leaves, if you find small white dots, like chalk ends, it is likely to be a red spider. The damaged leaves will lose their luster, and if they are not prevented in time, there will be a large number of fallen leaves, which will seriously affect the tree potential.
So how do we use Kermat to control red spiders? Everyone should remember that to prevent and control red spiders, you should usually pay attention to observation with a magnifying glass. It is necessary to take medicine immediately when its number is not large, if it is not used in time, once the red spider multiplies in large quantities, the amount and number of drugs will increase accordingly, and the cost will become larger. Because the g mite has the characteristics of a long period of validity, so do not worry about losing its effectiveness, you can make 73% g mite emulsion into 2000-2500 times liquid when each leaf has less than 5 heads, and then spray the leaf evenly, pay attention to the spraying must be meticulous, especially the main vein on the back of the leaf should also be sprayed, until the tree body is wet and dripping.
1. Gram mite is an acidic pesticide. Many farmers and friends are accustomed to mixing two or more pesticides to play the role of "one spray and multiple effects", but it should be noted that acidic pesticides cannot be mixed with alkaline pesticides, which will affect the efficacy.
2. As mentioned earlier, crete is a low-toxicity pesticide. Low toxicity is not non-toxic, so farmers and friends should be particularly careful when using it, avoid contact with the skin, wear long sleeves and masks when spraying, and usually put unused pesticides in places where children can't get them.
3. When using gram mite, the concentration cannot be increased arbitrarily, otherwise it is easy to produce drug damage. There is also attention to the use of temperature, it is best not to use in a low temperature environment, and it is better to use it when the temperature is more than 20 degrees.
4. Although the effect of Gram Mite in controlling red spiders is very good, it cannot be applied for a long time with a single agent, otherwise it will be easy to make red spiders resistant. It is best used interchangeably with other agents that kill red spiders, such as thiazone or biphenylhydrazide.
