Problems solved by technology

[0005] In the prior art, there is no literature report on whether the essential oil of Nepeta nepeta can be used for the control of tea geometrid
In addition, practice has proved that the long-term use of a single dose of chemical pesticides is prone to resistance problems, resulting in increasing dosage and increasing risks, which is not conducive to environmental and ecological safety

[0019] Bioassay Example 1 : Effects of Nepeta essential oil on the hatching rate of first-laid eggs of Tea Geometrid

[0020] Test object: tea inchworm

[0021] Specific test method:

[0022] 1) Accurately weigh the Nepeta fruit, use the steam distillation method, and extract continuously for 2 hours to obtain a light yellow oily liquid with a strong aroma, namely the essential oil of Nepeta nepeta. The extracted Nepeta essential oil was stored in a refrigerator at 4°C for later use.

[0023] 2) Determination of the effect of fumigation on the inhibition of hatching of the first eggs of the tea geometrid. Spread qualitative filter paper with a diameter of 90 mm in a plastic petri dish with a diameter of 90 mm, and properly spray water to keep it moist. The first eggs of tea geometrid were picked and placed in petri dishes (30 heads / dish).

[0024] 3) Then place a sterilized circular piece of filter paper with a diameter of 10 mm in the petri dish. Add a certain dose of N...

[0030] Bioassay Example 2 : Indoor Toxicity Determination of Nepeta Essential Oil and Osthole Composition to Tea Geometrid

[0031] Test object: tea inchworm

[0032] The test method is leaf soaking method. Immerse the fresh tea tips in the liquid medicine and dry the cuttings, cut off the dried tea tips and put them in canned bottles, with 3-4 tea tips per bottle, select 2nd instar larvae of the same size and put them into the canned bottle. Each treatment was inoculated with 15 worms, repeated three times, the temperature was controlled at 26-27°C, and the appropriate humidity was maintained, and normal fresh leaves were fed. The mortality rate was investigated 120 hours after administration, and the inhibitory intermediate concentration LC50 was calculated by the least square method, and the co-toxicity coefficient (CTC) was calculated by Sun Yunpei's method. When CTC120, the composition exhibits synergistic effect.

[0033] Actual toxicity index (ATI) = (standard drug...

Embodiment 1

[0043] Weigh 16g of nepeta essential oil, 0.8g of osthole, 12g of agricultural milk 500#, 8g of agricultural milk 1601#, and 150# solvent oil to 100g. The above raw materials are put into a mixing tank according to the conventional method for preparing cream and mixed to make active ingredient weight percentage of 16.8% Nepeta essential oil · osthole cream.

Abstract

The invention belongs to the technical field of pesticide application, and particularly relates to an insecticide composition containing chenopodium ambrosioides essential oil and a purpose of the insecticide composition. According to the purpose of botanical pesticide chenopodium ambrosioides essential oil, the chenopodium ambrosioides essential oil not only can be used for preventing and curing tea geometrid but also can be used for inhibiting the hatching rate of tea geometrid eggs. The chenopodium ambrosioides essential oil is used for fumigating eggs laid by the tea geometrid and has a relatively good inhibiting effect on the hatch of the eggs, and the inhibition rate is close to 100%. The chenopodium ambrosioides essential oil has a huge potential in the aspect of being developed into a novel botanical pesticide.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and in particular relates to a pesticide composition containing nepeta essential oil and its application. Background technique [0002] Plant essential oils are volatile secondary metabolites in plants. They are complex mixtures of various chemical components, generally containing dozens to hundreds of compounds. The main components include terpenes, alkaloids, flavonoids, organic acids, lipids Compounds such as phenols, phenols, thiophenes, and alkynes all have strong insecticidal activity. A large number of studies have shown that the active components of plant essential oils have high biological activity on target pests. They affect the nervous system, respiratory system, digestive system or endocrine system of insects through contact killing, food refusal, avoidance, fumigation, growth inhibition and reproduction. Insect metabolism, physiology, biochemistry, behavior, etc. inte...
