[0023] Bioassay Example 1 : Indoor Toxicity Determination of Camphor Leaf Essential Oil and Pesticide Synergistic Composition to Tea Geometrid
[0024] Test object: tea inchworm
[0025] 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 in particular relates to a pesticide synergistic composition containing camphor tree leaf essential oil and cyhalothrin and application thereof. The pesticide synergistic composition containing the camphor tree leaf essential oil and the cyhalothrin is prepared from an active component A and an active component B, wherein the active component A is the camphor tree leaf essential oil and the active component B is the cyhalothrin; the weight ratio of the active component A to the active component B ranges from (1 to 30) to (30 to 1). The pesticide synergistic composition provided by the invention has a remarkable synergistic effect and the drug dosage is reduced; insect pests with resistance on an existing medicament can be effectively prevented and treated; the pesticide composition provided by the invention can be used for treating various insect pests through one step of pesticide application once and the drug utilization cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of pesticide application, and in particular relates to a pesticide synergistic composition containing camphor tree leaf essential oil and kaufthrin 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 u...
