[0002] Pest control is an artificial means of reducing or preventing pathogenic microorganisms and pests from harming crops or humans and livestock. It can generally be divided into chemical control using chemical substances such as pesticides and physical control using physical energy such as light or rays or building barriers.

[0003] In order to eliminate or prevent pests and diseases in farmland, especially in farmland where crops are grown under plastic film, the existing method is to use "artificial root irrigation". A wooden stick is inserted into a hole near the root system of the crop to pour the pesticide solution into the hole, and then the hole is sealed. For crops with serious pests and diseases, it is sometimes necessary to insert several holes near the root area. The disadvantages of this method are: (1) the method is backward and wastes a lot of manpower; (2) it is inconvenient to control the quantitative injection of pesticides, which wastes pesticides.
