[0002] Stellera chamaejasme belongs to the genus Stellera chamaejasme of the family Thymelaeaceae. Stellera ), commonly known as heartbreak grass, steamed bun flower, red match head, dull-headed flower red wolfsbane, etc., is widely distributed in natural grasslands in Northeast, Northwest and Southwest my country. It is a highly toxic perennial poisonous plant; Wolfberry chamaejasme has a well-developed root system and strong reproductive ability. It can consume more soil nutrients and water, resulting in a reduction in available nutrients for other forages, resulting in a significant decrease in the yield and quality of high-quality forage, seriously hindering the development of local grassland animal husbandry. Traditional prevention and control methods mainly rely on manual digging or large-scale spraying of chemicals. Due to the large area of ​​wolfsbane occurrence and the high difficulty of physical prevention and control, chemical prevention and control is still the main means of grassland wolfsbane prevention and control. With the continuous enhancement of people's awareness of ecological environmental protection and the need to develop ecological organic animal husbandry, it is strictly forbidden to use high-residue pesticides on a large scale on natural grasslands to control grassland pests. Therefore, precise and targeted application of chemical pesticides has become a basic requirement for pesticide use.
