[0002] Crop disease and pest control is a key task in agricultural production, which is directly related to the yield and quality of crops, and further affects the efficiency of agricultural production. There are various types of crop diseases and pests, such as rice blast, wheat rust, corn borer, locust, rice planthopper, and powdery mildew. The occurrence of these diseases and pests is related to many factors, such as climate, soil, crop variety, cultivation management, etc. The main methods of crop disease and pest control include agricultural control, biological control, chemical control, and physical control. The main principle of chemical control is to interfere or destroy the physiological functions of diseases and pests by using chemical pesticides, such as insecticides, fungicides, and herbicides, so as to control or eliminate diseases and pests. These pesticides usually have toxicity and can kill or inhibit the growth and reproduction of diseases and pests.

[0003] In the process of rice planting, the rice grower usually uses a pesticide sprayer to spray pesticides on the rice. However, the existing pesticide sprayer needs to be held by hand and swung within the coverage range when spraying pesticides, and the coverage range is limited.
