Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of agricultural sterilization, insecticide and acaricide, and specifically relates to a pyrimidine-containing propene ether compound and a preparation method and application thereof. Background Art
[0002] The prevention and control of pests and diseases has always been the core area of pesticide scientific research, and the widespread use of pesticides has enabled it to be effectively controlled. However, with the continuous expansion of the scale of pesticide application, the problem of resistance of traditional pesticide varieties has become increasingly prominent, and the continuous emergence of new pests and diseases has made the research and development of new pesticides with high efficiency and low toxicity an inevitable choice.
[0003] The following patents report dihalopropene compounds with insecticidal and acaricidal activities: CN1137265, CN1318535, CN1681771, CN1780818, CN1780825, CN1860874, CN101208088, US5872137, US5922880, US6071861, US20060247283, US20050288186, US20040224994, US20070142229, WO2003074498, etc. The representative variety of this type of compound, pyridalyl, is a patented product of Sumitomo Chemical Co., Ltd. of Japan. It has excellent effects on a wide range of lepidopteran pests on vegetables and cotton. The structural formula is as follows:
[0004]
[0005] Pyrimidine compounds are an important class of fungicides developed since the 1950s. They are effective against various diseases caused by Botrytis cinerea. They act as mitochondrial complex I electron transfer inhibitors and are one of the few fungicides for which resistance has not yet been reported. They also have no cross-resistance with common fungicides. These properties indicate that pyrimidines are a class of potential compounds for the discovery of pesticide candidate varieties. For example, diflumetorim, which was approved for registration in Japan in 1997, has excellent control effects on wheat powdery mildew and rust (EP 0370704); and cyprodinil, a fungicide developed by Syngenta, has good control effects on gray mold, powdery mildew and black spot (EP 310550).
[0006]
[0007] Therefore, in order to continue to search for compounds with excellent biological activity from dihalopropene ether derivatives, we plan to adopt the principle of active substructure splicing to rationally combine the substituted pyrimidine group with the dihalopropene ether skeleton, and disclose a class of pyrimidine-containing propene ether compounds with good bactericidal and insecticidal activity.

[0008] The present invention provides a pyrimidine-containing propene ether compound and a preparation method and use thereof. The pyrimidine-containing propene ether compound of the present invention is used for preparing a drug for preventing and treating pathogens or pests and mites in agriculture or other fields. The compound of the present invention has a broad-spectrum fungicidal activity and has an excellent control effect on wheat powdery mildew, corn rust, etc. At the same time, it exhibits good insecticidal and acaricidal activity and has a high mortality rate against diamondback moth, armyworm, cinnabarinus spider mite, etc.

[0232] The samples of the compounds of the present invention were used to test the in vitro antibacterial activity or in vivo protective effect on various fungal diseases of plants. The results of the fungicidal activity test are shown in the following examples.
[0233] In vivo protective activity assay
[0234] The determination method is as follows: adopt the living potted plant determination method, that is, the sample of the compound to be tested is dissolved with a small amount of solvent (the type of solvent is such as acetone, methanol, DMF, etc., and is selected according to its solubility for the sample, and the volume ratio of the amount of solvent to the amount of spraying liquid is equal to or less than 0.05), and diluted with water containing 0.1% Tween 80 to prepare the required concentration of the test solution. On the crop sprayer, the test solution is sprayed on the disease host plant (the host plant is a standard potted seedling cultivated in a greenhouse), and the disease is inoculated 24 hours later. According to the characteristics of the disease, the diseased plants that need to be cultivated with temperature control and moisture retention are inoculated and placed in an artificial climate chamber for cultivation. After the disease infection is completed, they are moved to the greenhouse for cultivation. The diseased plants that do not need moisture retention cultivation are directly inoculated and cultivated in the greenhouse. After the control is fully diseased (usually one week), the disease prevention effect of the compound is evaluated.

[0252] The compounds of the present invention were used to carry out insecticidal activity tests on several insects. The test method is as follows:
[0253] The test compound was dissolved in a mixed solvent of acetone / methanol (1:1) and then diluted with water containing 0.1% (wt) Tween 80 to the desired concentration.
[0254] The insecticidal activity was determined by airbrush spraying with Plutella xylostella, Armyworm and Tetranychus cinnabarinus as targets.
[0255] (1) Determination of activity against Plutella xylostella
[0256] Test method: Use a punch to punch cabbage leaves into leaf discs with a diameter of 2 cm and use an airbrush to spray them at a pressure of 10 psi (about 0.7 kg / cm 2 ), spray each leaf disc on both sides, with a spray volume of 0.5 ml. After drying in the shade, 10 2nd-instar test insects were inoculated in each treatment, and each treatment was repeated 3 times. After treatment, they were placed in an observation room at 25°C and a relative humidity of 60-70%. After 72 hours, the number of surviving insects was investigated and the mortality rate was calculated.

After drying in the shade, 10 2nd-instar test insects were inoculated in each treatment, and each treatment was repeated 3 times. After treatment, they were placed in an observation room at 25°C and a relative humidity of 60-70%.

[0270] Determination method: Take two true leaf bean seedlings, inoculate them with adult spider mites and investigate the base number, then use an airbrush sprayer to treat the whole plant at a pressure of 10 psi (about 0.7 kg / cm 2 ), the spray volume was 0.5 ml. Each treatment was repeated 3 times, and the mites were placed in a standard observation room after treatment. The number of surviving mites was investigated after 72 hours, and the mortality rate was calculated.
[0271] Some of the test results on Tetranychus cinnabarinus are as follows:
[0272] At a dose of 600 ppm, the lethality of compounds 2-50 and others to Tetranychus cinnabarinus was 100%;
[0273] At a dosage of 100 ppm, the lethality of compounds 2-50 and others to Tetranychus cinnabarinus was 100%;
