Locusts, as a very destructive agricultural pest, have been a headache for farmers since ancient times. In recent years, with global climate change and the deterioration of the ecological environment, the locust plague has become more and more serious. So, how do we deal with the locust plague? This article will introduce you to several ways to get rid of locusts.
1. Biological control law.
Biological control is a method of controlling locust populations by using biological factors such as natural enemies and pathogenic microorganisms. At present, China has successfully developed a biological pesticide called "Metarhizium aeruginosa", which has a good control effect on locusts. In addition, the density of locusts can also be reduced by introducing natural enemies of locusts, such as lizards, birds, etc.
2. Chemical control method.
Chemical control is the use of chemical pesticides to eliminate locusts. At present, commonly used chemical pesticides include organophosphorus, carbamates, pyrethroids, etc. When using chemical pesticides, it is necessary to pay attention to choosing the appropriate agent and dosage, and operate in strict accordance with the instructions, so as not to cause harm to the environment and the human body.
3. Physical prevention and control method.
Physical control is the use of physical means to exterminate locusts. For example, during the locust laying period, the locust spawning environment is destroyed by plowing the land and removing weeds. In the larval stage of locusts, tools such as insect trap lamps and sticky insect boards can be used to trap and kill.
Fourth, the comprehensive prevention and control law.
The comprehensive control method is to combine various methods such as biological control, chemical control, and physical control to give full play to their respective advantages and achieve the goal of comprehensive control of locusts. In practice, corresponding control plans can be formulated according to the occurrence law of locusts, the ecological environment, and agricultural production.
The work of locust plague prevention and control has a long way to go, and we need to work together. Hopefully, the methods presented in this article to get rid of locusts will be helpful to you.
