[0028] indoor bioassay experiment

[0029] 1.1 Experimental method

[0030] 1.1.1 Drug preparation

[0031] 50% clothianidin and 2.5% bifenthrin were formulated into 10,000 mg / L mother liquor for later use; 2.5% bifenthrin was provided by Nanjing Red Sun Co., Ltd. Each compound ratio of clothianidin and bifenthrin was diluted into 5-7 concentration gradients.

[0032] 1.1.2 Film production

[0033] Prepare a 9cm-diameter petri dish, take a 9cm-diameter qualitative filter paper and put it on the bottom of the dish, absorb 1ml of the prepared medicine solution and evenly drop it on the filter paper, make a medicine film after the solvent evaporates, and place it for 24 hours before use.

[0034] 1.1.3 Treatment method

[0035] Use a brush to screen 15 test insects with the same physiological state, and move them into a petri dish lined with a filter paper film. After they crawl on the filter paper film for 1 hour, transfer the test insects to a clean petri dish with young le...

Embodiment 2

[0059] Field efficacy evaluation test

[0060] According to the optimal compounding ratio of clothianidin and bifenthrin 22.5:2.5 selected in-house, a 25% clothianidin-bifenthrin aqueous emulsion was prepared, which contained 22.5% clothianidin and 2.5% bifenthrin permethrin. The efficacy test was carried out in the field with 20% imidacloprid soluble liquid as the control agent.

Abstract

The invention relates to an insecticidal compound containing clothianidin and bifenthrin as effective components and an application thereof. The insecticidal compound provided by the invention is mainly used in the research and application of controlling whitefly and aphid. The insecticidal compound provided by the invention is characterized by containing the active components of clothianidin and bifenthrin. The compound contains 0.1-50 wt% of clothianidin, 50-0.1 wt% of bifenthrin and the balance being auxiliary components which are allowed and can be accepted in pesticides. The insecticidal compound provided by the invention can be applied to control a plurality of Hemiptera, coleopteran and Lepidoptera insects, such as whitefly, plant hopper, aphid, leafhopper, thrip, Psylla chinensis Yang et Li, Myzus persicae, yellow aphids, Myzus persicae, pod borer and the like, on paddy rice, vegetables, fruit trees and other crops. The insecticidal compound provided by the invention has an outstanding effect of controlling lepidoptera insects and piercing-sucking insects on crops.

Description

technical field [0001] The invention relates to an insecticidal composition with clothianidin and bifenthrin as active ingredients and an application thereof, belonging to the technical field of insecticidal compositions and pesticides. Background technique [0002] Neonicotinoids are a class of highly efficient, safe, and highly selective new insecticides. Their effects are similar to those of nicotinic acetylcholine receptors, and they have contact, stomach poisoning, and systemic activities. Neonicotinoids have become the fastest-growing class of chemical insecticides because of their chemical and biological characteristics such as broad insecticidal spectrum, low dosage, good systemic and plant conduction, novel mechanism of action, and high environmental compatibility. Widely used in rice, vegetables, fruit trees and other crops to control Hemiptera, Coleoptera, Diptera and some Lepidoptera pests, imidacloprid acetamiprid has been a relatively successful precedent. ...
