First of all, let's confirm the types of mites. There are basically three types of mites, namely red spiders, two-spot spider mites and tea yellow mites, and two-spot spider mites can also be called white spiders. Red spiders 1. Reasons why red spiders are difficult to control Most growers do not have the concept of prevention in advance when preventing and controlling diseases and insect pests. But in fact they do not know that when the field has actually seen the damage of mites, it has already had an impact on the quality and yield of crops , and then took other measures to remedy, the effect is not as great as prevention in advance, and the mites and other pests are also different, and it is more difficult to control after the pests occur.
The base of insect Country Email List sources is large. Red spiders, two-spotted spider mites and tea yellow mites have strong adaptability and short growth and reproduction cycles. They can reproduce 10-20 generations per year. Each female adult can lay About 100 eggs each time. The rapid incubation after temperature and humidity results in a particularly large number of insect sources in the field, which increases the difficulty of control. (2) Complete prevention and treatment. Mites on vegetables are generally small in size and like to survive on the back of leaves, and there are many leaves that fold. It is widely distributed in farmland, such as litter, weeds, surface or Branches and other relatively hidden places, which increases the difficulty of control. In addition, due to their small size and light weight, mites are easy to move under the action of the wind, which will also increase the difficulty of control.
Unreasonable prevention and control agents. Many people's understanding of mites is still based on the concept of red spiders, and they think that they can be cured as long as they take abamectin. In fact, the use of abamectin to control red Spiders have been used for many years. Although some resistance has been developed, the control effect on red spiders is still relatively good. However, the control effect of the two-spotted spider mites and the yellow tea mites is greatly reduced, so in many cases, It is an important reason for the unsatisfactory pest control effect due to insufficient understanding. (4) The way of drug use is crooked. A lot of growers spray a lot, but I don't think a lot of people do it. When controlling mites in the field, many people are still lazy and afraid of the back sprayer, So they choose the method of rapid spraying.
