[0024] Bioassay Example 1 : Determination of Indoor Toxicity of Camphor Leaf Essential Oil and Nepeta Essential Oil Synergistic Composition to Tea Geometrid

[0025] Test object: tea inchworm

[0026] 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.

Abstract

The invention belongs to the technical field of application of pesticides, and particularly relates to a botanical pesticide synergistic composition and application thereof. The botanical pesticide synergistic composition comprises an active ingredient A and an active ingredient B according to a weight ratio of 1:30 to 30:1, wherein the active ingredient A is essential oil of camphor tree leaves, and the active ingredient B is essential oil of chenopodium ambrosioides. The botanical pesticide synergistic composition has the advantages that the obvious synergistic action is realized, the usage amount of pesticide is reduced, and the pests which have produced resistance on the existing pesticide can be effectively prevented and controlled; after applying once, multiple types of pests can be controlled, and the cost of pesticide applying is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and in particular relates to a botanical pesticide synergistic composition containing camphor leaf essential oil and nepeta essential oil and its application. Background technique [0002] Camphor tree (Cinnamomum camphora), also known as camphor, black camphor, camphor, camphor, etc., is an evergreen tall broad-leaved tree of the family Lauraceae. Camphor tree is one of the natural spice trees in my country. Its roots, stems, leaves, fruits and other parts can be extracted to separate essential oils. The chemical components of camphor tree essential oil are very rich, and there are about 300 chemical components in camphor tree leaf essential oil. The main components of camphor leaf essential oil include linalool, safrole, camphor, borneol, nerolidol, isonerolidol, citral, geraniol and other compounds; most of the chemical components are bactericidal, insecticidal , Antibacterial ...
