Problems solved by technology

[0007] Cantharidin is a natural monoterpenoid insect toxin that exists in insects such as Coleopera (Coleopera) and Meloidae (Meloidae). The natural resources are very scarce, so the development and utilization of its products are limited.

Embodiment 1

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

[0016] Select suitable solvent, emulsifier, prepare 1.0% cantharidin emulsifiable concentrate, and prepare cantharidin and cypermethrin mixture, in the mixture, cypermethrin 1.9% (percent), cantharidin 0.10% (percent), emulsifier 10%, The solvent is supplemented to 100%, that is, 2.0% cantharidin-cypermethrin EC is prepared. 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.

[0017] As can be seen from the measurement data in Table 1, the CTC value of the mi...

Embodiment 2

[0019] Embodiment 2: synergistic compounding of cantharidin and fenvalerate

[0020] Select suitable solvent, emulsifier, solvent, prepare cantharidin and fenvalerate mixed agent microemulsion, fenvalerate 9.8% (percentage), cantharidin 0.20% (percentage), emulsifier 18% in the mixture , the solvent is 20%, the deionized water is supplemented to 100%, and the microemulsion preparation method is adopted 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

[0023] Embodiment 3: synergistic compounding of cantharidin and cyhalothrin

[0024] Select suitable solvent, emulsifier, prepare cantharidin and cyhalothrin mixed agent microemulsion, in the mixed agent, cyhalothrin 0.95% (percentage), cantharidin 0.05% (percentage), emulsifier 17%, solvent is 20% %, make up to 100% with deionized water, and adopt the pesticide microemulsion preparation process to prepare 1.0% cantharidin·cyhalothrin microemulsion. 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 a pesticide composition containing cantharidin, which comprises the following constituents (by mass percent): cantharidin 0.1-10.0%, insecticide 0.1-30.0%, and balancing auxiliary agent for pesticides.

Description

technical field [0001] 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 [0002] 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: [0003] [0004] Cantharidin crystallizes as rhombic prisms in acetone, white needles in chloroform, and white bran flakes in ethanol. The melting point determined by capillary method is 215-216.8°C. Insoluble in cold water, hardly soluble in ether (1g / 700ml), solubility in chloroform, dichloromethane, acetone, ethyl acetate ...
