[0025] Bioassay Example 1 : Indoor Toxicity Determination of Composition of Camphor Leaf Essential Oil and Azadirachtin to Plutella xylostella

[0026] Test object: Cabbage diamondback moth

[0027] The test method is leaf drug film method. Take fresh cabbage leaves without pesticide pollution and soak them in a series of concentrations of camphor tree leaf essential oil and azadirachtin for 10 seconds, and use distilled water as a control, and let them dry indoors. After drying, cut into discs of appropriate size and place them in a 9cm petri dish, insert 3rd instar larvae of the same size, repeat 3-4 times for each concentration, 10-20 larvae for each repetition, and count the mortality after 48 hours , using the least squares method to calculate the LC50 value of the inhibitory concentration. Then calculate the co-toxicity coefficient (CTC) according to Sun Yunpei's method. When CTC120, the composition exhibits synergistic effect.

[0034] Bioassay Example 2 : Indoor Toxicity Determination of Camphor Leaf Essential Oil and Osthole Composition to Tea Geometrid

[0035] Test object: tea inchworm

[0036] 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 pesticide application, and particularly relates to a camphor leaf essential oil-containing plant-sourced pesticide composition and application thereof. The camphor leaf essential oil-containing plant-sourced pesticide composition comprises an active component A and an active component B, wherein the active component A is camphor leaf essential oil, the active component B is azadirachtin, and the weight ratio of the active component A to the active component B is (1:30)-(30:1). The pesticide composition has a significant synergistic effect, so that the dosage is reduced; the pesticide composition can effectively control pests having resistance to the conventional pesticides; the pesticide composition can control a variety of pests through one-time application, so that the application cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and in particular relates to a botanical pesticide composition containing camphor tree leaf 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 effect, widely used in light ind...
