Embodiment Construction

[0012] The present invention will be further described through specific examples below. Those skilled in the art should understand that the following examples are only for a better understanding of the present invention and are not used to limit the present invention in any way.

[0013] Two sulfonamide compounds according to Formula I and Formula II were purchased from Beijing Inokay Technology Co., Ltd., and the codes are marked as VS03 and VS04, and their structural formulas are as follows:

[0014]

[0015] Use them as the active ingredients of pesticides and configure them into different concentrations of liquid medicines to perform the following test experiments.

[0016] Aphid killing activity test experiment

[0017] Experimental test insects: Soybean aphid (Aphis glycines) was collected from a normal population raised indoors, and wingless adults with the same age, body weight and physiological status were used for pesticide activity screening test.

Abstract

The invention discloses application of sulfanilamide compounds in prevention and control of agricultural insects. The sulfanilamide compounds have a structural formula as shown in the formula I or formula II in the specification, wherein R1 represents hydrogen, C1-C4 alkyl, C1-C4 halogenated alkyl, C1-C4 alkoxy, C1-C4 alkyl sulphanyl, halogen, nitryl, cyan, azido, hydroxy or trifluoromethyl; R2 represents isopentene group, C1-C10 alkyl, benzene ring, pyridine, thiazole, thiophene, pyrrole, furan, pyrazole, imidazole, pyran, pyrazine, pyrimidine, pyridazine, benzofuran, benzothiophene, indole, quinoline, trifluoromethyl or halogen. The pesticides prepared by taking the compounds shown in the formula I and formula II as active ingredients have good aphid killing activity, and shows low toxicity to non-targeted bees.

Description

Technical field [0001] The present invention relates to the application of sulfonamide compounds in the prevention and control of agricultural pests. Background technique [0002] The neonicotinoid insecticide represented by imidacloprid is a new generation of insecticide with milestone significance after organophosphorus, organic ammonia, carbamate and pyrethroid. Because of its high efficiency, wide insecticidal spectrum, it is particularly prominent in the control of piercing and sucking mouthparts pests. It has root systemic, contact killing and stomach poisoning effects, low residue, environmental friendliness, and safety to mammals and aquatic organisms. Application, occupies a major share of the global pesticide market, and global annual sales continue to grow, reaching or exceeding hundreds of millions of dollars (Kagabu SJAgric. Food Chem. 2011, 59, 2887-2896). [0003] Due to the improper use and unreasonable application of pesticides, the resistance and cross-resistance...
