Abstract

The invention provides an enzyme linked immunosorbent assay kit for detecting triadimenol. The enzyme linked immunosorbent assay kit comprises an enzyme-labeled plate coated with a triadimenol coupling antigen, a triadimenol monoclonal antibody, an enzyme-labeled antibody, a triadimenol standard solution, substrate coloring liquid, a stop solution, washing liquid and reconstitution fluid. The invention further discloses a method using the enzyme linked immunosorbent assay kit to detect triadimenol residual quantity. The method includes: preprocessing a sample, detecting with the kit, and analyzing the detection result. The enzyme linked immunosorbent assay kit can be used for detecting the residual quantity of the triadimenol in tobacco and is simple to operate, low in cost, high in sensitivity, capable of achieving on-site monitoring and suitable for the screening of a large amount of samples.

Description

technical field [0001] The invention relates to an enzyme-linked immunoassay detection technology, in particular to an enzyme-linked immunoassay kit for detecting triadimenol, which is particularly suitable for detecting the residual amount of triadimenol in tobacco leaves. Background technique [0002] Triadimenol (triadimenol, C 14 h 18 CN 3 o 2 ) also known as Baidan, the chemical name is 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)-2-butane Alcohol is a low toxicity, broad-spectrum, high-efficiency systemic fungicide. Its main mechanism of action is to inhibit the biosynthesis of gibberellin and ergosterol and then affect the cell division rate. It is effective against tobacco root black rot and powdery mildew. , Frog eye disease and other fungal diseases have a good control effect. Therefore, it is widely used in agricultural production in our country, and is suitable for crops such as wheat, corn, sorghum, fruits and vegetables, and tobacco. [0003...
