Abstract

The invention relates to a pesticide composition containing a chenopodium ambrosioides and common peganum seed extract as well as a preparation method and application of the pesticide composition, belongs to the field of pesticides, and aims to solve the technical problem of providing the pesticide composition containing the chenopodium ambrosioides and common peganum seed extract as well as the preparation method and application of the pesticide composition. The active components of the pesticide composition containing the chenopodium ambrosioides and common peganum seed extract are extracted from the following raw medicinal materials in parts by weight: 1 part of chenopodium ambrosioides and 0.5-6 parts of common peganum seed; the active components can be prepared through the steps of mixing the raw medicinal materials, namely, chenopodium ambrosioides and common peganum seed, and extracting together, and can be prepared through the steps of separately extracting chenopodium ambrosioides to obtain a chenopodium ambrosioides extract, separately extracting common peganum seed to obtain a common peganum seed extract, and mixing the two extracts. The pesticide composition containing the chenopodium ambrosioides and common peganum seed extract can kill acarina, homoptera and hemiptera pests such as polyphagotarsonemus latus, aphid, trialeurodes vaporariorum and lugus lucorum, and has positive significance for agricultural production.

Description

technical field [0001] The invention relates to a pesticide composition containing extracts of schizonepeta and camel cape seeds, a preparation method and an application, and belongs to the field of pesticides. Background technique [0002] Nepeta chinensis belongs to the Chenopodiaceae plant, and its whole herb is used as medicine, which has the functions of expelling wind, dehumidification, killing insects, and relieving pain. Nepeta nepeta is rich in volatile oil, and its volatile oil has various activities or functions such as sedation, analgesia, insect repellent, antibacterial, anti-oxidation, etc., especially has a significant inhibitory and bactericidal effect on plant pathogenic fungi, and has a wide range of antibacterial properties . However, the volatile oil of Nepeta nepeta has not been formulated yet, and its microencapsulation can avoid the influence of external conditions such as light, oxygen, temperature, and pH value, and prolong the duration of efficacy....
