Myclobutanil is a triazole chemical used as a fungicide. It is a steroid demethylation inhibitor, specifically inhibiting ergosterol biosynthesis. Ergosterol is a critical component of fungal cell membranes. When heated, myclobutanil decomposes to produce corrosive and/or toxic fumes, including carbon monoxide, carbon dioxide, hydrogen chloride, hydrogen cyanide, and nitrogen oxides. Myclobutanil is banned in Canada, Colorado, Washington, and Oregon for the production of medical and recreational marijuana. In 2014, a Canadian news investigation by The Globe and Mail reported the discovery of myclobutanil in medical marijuana produced by at least one government licensed grower. In September 2019, NBC News commissioned CannaSafe to test THC cartridges for heavy metals, pesticides, and residual solvents like Vitamin E; pesticides, including myclobutanil, was found in products from unlicensed dealers. In Michigan, the current state action limit for myclobutanil is 200 ppb in cannabis products.
A dCAPS molecular marker for detecting residual amount of propamocarb in cucumber fruits and application thereof
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.

Medicine formula for treating strawberry powdery mildew and use method
The invention discloses a medicine formula for treating strawberry powdery mildew and a use method, and relates to the technical field of pesticides. The formula comprises bupirimate and myclobutanil as active components, a modified bentonite composite carrier as a carrier, and a plurality of auxiliary components. The preparation method comprises the steps of microencapsulation, carrier adsorption and the like. During use, the pesticide is applied when scabs appear in diseases, and the pesticide is diluted with water and then sprayed. Field tests show that the pesticide formula is high in control effect and long in lasting period and is remarkably superior to a single agent and an unmodified carrier formula, the problems that an existing agent is insufficient in drug resistance and synergistic effect, short in lasting period and the like are effectively solved, the dosage and the number of times of pesticide application can be reduced, and the risk of pesticide residues can be reduced.

A conazole hapten, antigen, antibody, and methods of making and using the same
The present application relates to the field of immunoassay technology, and provides a myclobutanil hapten, antigen, antibody and preparation method and application. The present application introduces an active group at the meta position of the chlorine atom on the benzene ring of myclobutanil. Compared with the existing hapten, the hapten provided by the present application completely simulates the structure of myclobutanil, and enhances the immunogenicity of the antigen. The antigen provided by the present application has strong immunogenicity after being coupled with a carrier protein. After injection immunization of mice, the titer of the produced antibody is 5.0x10 4 , the half-inhibitory concentration (IC 50 ) is about 50 ppb, and the minimum detection limit of colloidal gold for myclobutanil in dry tobacco leaf samples is about 2.5 μg / g.

A fungicide composition for preventing and treating avocado root rot
The application belongs to the technical field of pesticides, and particularly relates to a fungicide composition for preventing and treating oil olive trunk rot. The fungicide composition for preventing and treating oil olive trunk rot is prepared by binary compounding pyridine amide, myclobutanil, mancozeb or trifloxystrobin according to a mass ratio of 1-150:150-1. The pyridine amide is compounded with various existing pesticide components, and the compounding formula of the pyridine amide, myclobutanil, mancozeb or trifloxystrobin is screened out. The pyridine amide, myclobutanil, mancozeb or trifloxystrobin shows a synergistic effect on inhibiting the growth of the pathogenic fungus causing the oil olive trunk rot, can improve the prevention and treatment effect on the oil olive trunk rot, and can further reduce the application dose of the pesticide, relieve the environmental pollution and the pesticide residue.

Myclobutanil hapten MY-6, artificial antigen, nano antibody as well as preparation method and application of myclobutanil hapten MY-6 and artificial antigen
The invention discloses a myclobutanil hapten MY-6, an artificial antigen, a nano antibody as well as a preparation method and application of the myclobutanil hapten MY-6 and the artificial antigen. The overlapping degree of the hapten MY-6 and the skeleton structure of myclobutanil to be detected is high, so that the immunogenicity of the hapten MY-6 is effectively improved; the hapten MY-6 is further utilized to prepare a nano antibody Nb MY-21 capable of specifically recognizing myclobutanil, and the antibody also has excellent organic solvent tolerance and acid-base resistance. According to the present invention, the ELISA detection method is established based on the nanometer antibody, the myclobutanil detection range of the method is 0.63-10.77 ng / mL, the half inhibitory concentration (IC50) is 2.61 ng / mL, the minimum detection limit is 0.34 ng / mL, and the detection sensitivity is high; therefore, the nano antibody Nb MY-21 can be well applied to actual sample detection of myclobutanil residues, and also has extremely high application value in preparation of myclobutanil detection products.
