Problems solved by technology

Biopesticides are directly using biologically produced active substances or living organisms as pesticides, as well as artificially synthesized pesticides with the same structure as natural compounds. Although they are environmentally friendly and do not pollute the environment, they have a short duration of efficacy in the field and are susceptible to The influence of environmental factors such as sunlight, temperature and humidity leads to low insecticidal effect and fails to meet the requirements of stable and long-term control

The invention also discloses a preparation method of the above-mentioned pharmaceutical composition for preventing and controlling organic tea garden seedling diseases and insect pests, comprising: stirring berberine, annonaline, polyoxyethylene octylphenol ether-10, and ethanol to obtain a premix; Add bentonite to water and stir to form a slurry, add octadecyltrimethylammonium chloride and sodium pyrophosphate to stir, filter, wash, dry, and pulverize to obtain pretreated bentonite; pretreated bentonite, eucalyptus magnanimum essential oil, tea tree oil, peppermint Oil grinding for 4-10min, the grinding speed is 10000-12000r / min, the grinding pressure is 1.2-1.4MPa, the grinding temperature is controlled to be less than or equal to 40°C, and the metrhizium anisopliae agent is added and mixed evenly to obtain the pretreated essential oil; the pretreated essential oil, pretreated The mixed solution is fully stirred, then added with a film-forming aid, stirred evenly, dried, and pulverized to obtain a pharmaceutical composition for preventing and controlling organic tea plantation plant diseases and insect pests.

Description

technical field [0001] The invention relates to the technical field of tea garden management, in particular to a pharmaceutical composition for preventing and treating pests in the seedling stage of organic tea gardens and a preparation method thereof. Background technique [0002] Tea is a drink made from the leaves or buds of the tea tree plant that originated in China. It is the current mainstream drink in China and plays an important role in entertaining guests and giving gifts to friends. Tea refers to the leaves and buds of the tea tree, also known as 槚, Ming, and 荈. The tea polyphenols contained in tea have strong antioxidant properties and physiological activities. They are scavengers of free radicals in the human body and can block the synthesis of various carcinogens such as amine nitrite in the body. [0003] At present, tea production is gradually becoming intensive. The existing tea tree planting process requires the prevention and control of diseases and insec...
