Embodiment 1

[0015] Embodiment 1: synergistic compounding of cantharidin and cypermethrin

[0016] Select a suitable solvent and emulsifier, prepare 1.0% cantharidin EC, and prepare a mixture of cantharidin and cypermethrin. In the mixture, cypermethrin is 1.9%, cantharidin 0.10%, emulsifier 10%, and the solvent is supplemented to 100%, that is, the preparation into 2.0% cantharidin · cypermethrin EC. The toxicity of single and mixed agents of cypermethrin and cantharidin to Plutella xylostella was determined by using the method of dipping insects and leaves, using the third-instar diamondback moth provided by the insect culture room of Northwest A&F University's Pollution-free Pesticide Research Service Center as test insects. On this basis, the co-toxicity coefficient CTC value of the mixture was calculated by Sun Peiyun's method, and the specific measurement results are shown in Table 1.

Embodiment 2

[0020] Embodiment 2: synergistic compounding of cantharidin and fenvalerate

[0021] Select suitable solvent, emulsifier, prepare cantharidin and fenvalerate microemulsion, in the microemulsion, fenvalerate 9.8%, cantharidin 0.20%, emulsifier 18%, solvent is 20%, and deionized water makes up to 100% %, adopt the microemulsion preparation method to prepare 10.0% cantharidin·fenvalerate microemulsion. Using the method of dipping insects and leaves, using the third-instar diamondback moth provided by the insect culture room of Northwest Agriculture and Forestry University's Pollution-free Pesticide Research Service Center as test insects, the indoor toxicity of single and mixed agents of fenvalerate and cantharidin to diamondback moth was determined. force. On this basis, the co-toxicity coefficient CTC value of the mixture was calculated by Sun Peiyun's method, and the specific measurement results are shown in Table 2.

Embodiment 3

[0026] Embodiment 3: synergistic compounding of cantharidin and cyhalothrin

[0027] Select suitable solvent, emulsifier, prepare cantharidin and cyhalothrin microemulsion, cyhalothrin 0.95% in the microemulsion, cantharidin 0.05%, emulsifier 1.7%, solvent is 20%, make up to 100% with deionized water %, the pesticide microemulsion preparation process is adopted, that is, 1.0% cantharidin·cyhalothrin microemulsion is prepared. The indoor toxicity of cyhalothrin and cantharidin single agent and mixed agent to diamondback moth was determined by using the method of soaking insects and leaves, using the third instar diamondback moth provided by the insect culture room of the pollution-free pesticide research service center of Northwest Agriculture and Forestry University as the test insect . On this basis, the co-toxicity coefficient CTC value of the mixture was calculated by Sun Peiyun's method, and the specific measurement results are shown in Table 3.

Abstract

The invention discloses an insecticide composition containing cantharidin. The insecticide composition contains the following components in mass percentage: cantharidin: 0.1%-0.5%, abamectin 0.9%, and the balance is pesticide auxiliary The pesticide adjuvant is composed of a well-known solvent, emulsifier and water, and the total of the raw materials is 100%. The pesticide composition can be formulated into emulsifiable concentrate or microemulsion. The specific measurement result of the co-toxicity coefficient CTC value of the pesticide composition shows that it has a significant synergistic effect and is an excellent pesticide combination. thing.

Description

[0001] The present invention is a divisional application of the patent application No. 200610159481.6 entitled "A Cantharidin-Containing Insecticide Composition", and the original application date is November 10, 2005. technical field [0002] The invention relates to an insecticide composition, in particular to a synergistic composite composition of cantharidin, an animal-source insecticide active ingredient, and an insecticide. Background technique [0003] Cantharidin (Cantharidin, C 10 h 12 o 4 ) is a natural monoterpene insect toxin that exists in insects such as Coleopera (Coleopera) and Meloidae (Meloidae), and is a defensive substance in the cantharis. The chemical name of cantharidin is exo type, 1,2 cis-dimethyl, 3,6-oxo bridge hexahydrophthalic anhydride; the molecular weight is 196.2, and the structural formula is as follows: [0004] [0005] Cantharidin crystallizes as rhombic prisms in acetone, white needles in chloroform, and white bran flakes in ethano...
