The application discloses a dCAPS molecular marker for detecting a residual amount of a cucumber fruit myclobutanil and application thereof, and relates to the technical field of molecular markers.The dCAPS molecular marker is derived from a SNP at a position of 158 of a CsABCI19 gene promoter.The dCAPS molecular marker is applied to detection of a residual amount of a cucumber fruit myclobutanil.The method comprises the following steps: (1) extracting DNA; (2) performing a PCR reaction; and (3) performing Nco I enzyme cutting, so that two band types are obtained, one is 491 bp, corresponding to SNP A, and the other is 444 bp and 48 bp, corresponding to SNP G, and the two types are identified as a fruit low myclobutanil residual amount germplasm and a fruit high myclobutanil residual amount germplasm respectively.The verification result of the dCAPS molecular marker in the germplasm resource shows that the identification result of the molecular marker is consistent with the phenotype, and the dCAPS molecular marker can be used for rapidly identifying the cucumber germplasm resource with a low myclobutanil residual amount in a fruit, and is a good breeding auxiliary selection marker.

The invention discloses a micro-capsule suspending agent containing fluroxafen and propamocarb as well as a preparation method and application of the micro-capsule suspending agent, and belongs to the field of agricultural plant protection. The flurobixafen and propamocarb microcapsule suspending agent disclosed by the invention is prepared by taking polymethylene polyphenylene isocyanate and PEG400 (Polyethylene Glycol 400) as capsule wall materials through an interfacial polymerization method. The bactericidal composition has a good control effect on various crop diseases, has an obvious synergistic effect compared with a single agent, is remarkably improved in bactericidal activity, greatly delays the generation of drug resistance of germs, broadens the bactericidal control spectrum, and is quick and more durable in effect, stable in capsule wall structure, prolonged in pesticide lasting period, reduced in pesticide application frequency, reduced in phytotoxicity risk and safe to crops.

The application belongs to the field of preparation and application of catalysts, and provides a preparation method of a catalyst for synthesizing 2,6-diethyl anilino ethyl propyl ether, wherein the catalyst uses copper and aluminum salt as a metal source and an alkali solution as a precipitant, a copper-aluminum spinel catalyst is prepared by using a chemical co-precipitation method, and the catalyst is applied to the synthesis reaction of 2,6-diethyl anilino ethyl propyl ether which is an important intermediate of propamocarb. After process optimization, the application has the advantages of strong reaction selectivity, high yield, good color and high purity of the product, easy availability of the reaction raw material, simple operation, simple post-treatment, and repeated cyclic use of the copper-aluminum spinel catalyst, and not only meets the requirements of green chemistry, but also has important significance for energy saving and emission reduction.

A method of controlling or preventing late blight caused by Phytophthora infestans in Solanum species comprising applying a composition comprising mandipropamid and propamocarb, or a salt thereof, to

Cucumber CsSTAR2 gene and its encoded protein are applied to reduce pesticide propamocarb residue, and the present application relates to the field of molecular biology.The nucleotide sequence of cucumber CsSTAR2 gene and the amino acid sequence coded by cucumber CsSTAR2 gene are disclosed.The protein expressed by CsSTAR2 gene, expression vector, transgenic cell or engineering bacteria are disclosed.The application of CsSTAR2 gene in reducing pesticide propamocarb residue is disclosed.In the expression mode of CsSTAR2 in response to propamocarb, it is shown that CsSTAR2 can quickly respond to the induction of propamocarb and play a function in low propamocarb residue of fruits.In the CsSTAR2 overexpression plant, the propamocarb residue of fruits is lower than that of wild type plant;the propamocarb residue in CsSTAR2 gene editing plant is higher than that of wild type plant, and there is a very significant difference, and CsSTAR2 has the function of positively regulating the low propamocarb residue of cucumber fruits.

The application discloses a method for removing propamocarb in plant extracts, and belongs to the technical field of pesticide residue removal, which comprises the following steps: S1. adjusting the pH of the dissolved solution of the dissolved extract to 8-12, and then performing cation exchange resin chromatography to collect an eluate; and S2. adjusting the pH of the eluate to 4-6, and then concentrating to obtain a removal product. The application is used for overcoming the technical problems that the existing technology cannot completely remove propamocarb or damages effective components, and therefore provides a method for removing propamocarb in plant extracts. The application uses the existence state difference of effective components and propamocarb in plant extracts under different pH environments and the method of ion exchange selective adsorption to efficiently remove propamocarb, while ensuring the recovery of the effective components, and improves the safety of the plant extracts.
