The red spider is a type of pest capable of completely devastating a crop in just a few days. They usually occur when high temperatures arrive and it is not easy to be able to end them.
Once it has reached the plant they are responsible for absorbing the liquid from them, causing chlorotic spots to occur in the leaf beam. They make it dry to the point that the plant can die.
The worst of all of this plague is its high reproductive power. They have a short life cycle, so they can disperse much faster than any other pest.
The spiders have a size that will range between 0.4-0.6mm, so it is difficult to see them with the naked eye; The most common is to use a magnifying glass.
If you are looking for a good chemical treatment for the red spider and end the problem, now that you are on time, we will try to give you a good solution.
Red spider: chemical treatment
The reduction of the population of the red plague requires managing several methods, in addition to establishing rigorous control strategies (chemical + biological + cultural control).
The main chemical treatments used to fight the red spider are the following:
- Mite growth inhibitors:Using active substances such as Clofentezin , Etoxazol or
- Chlorine channel activator:In this case we will use the active substance Abamectin .
- Electron transport inhibitors:In this process some active substances such as Piridaben, Fenpiroximato or Tebufenpirad come into play .
- Inhibitors of mitochondrial ATP synthesis:The active substance of Propargite is used .
- Inhibitors of lipid synthesis:This chemical treatment of the red spider is usually used based on the active substance of Spirodiclofen .
- Mode of physical action due to suffocation:In this case a vegetable oil diluted to 79% is used.
Of course, all these chemical applications must be managed with recommended doses according to the volume of the red spider population, as well as the density of the crop to be treated. The application techniques should be extended until the underside of the sheets is reached; since this is the key point where the plague is usually located. At the same time it must provide complete coverage to the plant, to prevent the spider from freely walking through it.
A common chemical practice that is used as a method of prevention is the application of herbicides directly on the bare soil, thus preventing the pest from approaching the plant.
As levels of cultural control, it is important to maintain good conditions of high humidity in the foliage of the plant, while regulating irrigation, since in this way the proliferation of the pest will be maintained to some extent.
Crop rotation techniques, fertilization techniques (or too much nitrogen load), or varied biological treatments can also be used.
