Description

Technical Field

[0001] The utility model belongs to the technical field of pyrethroid residue detection, and particularly relates to a pyrethroid residue detection device. Background Art

[0002] During the process of fruit trees growing to flowering and bearing fruit, fruit farmers will spray pesticides on the fruit trees to kill insects. Pyrethroid pesticides have the advantages of high insecticide efficiency, fast speed and low toxicity. Therefore, they are widely used in the process of fruit planting. The problem of pesticide residues in fruits has always been a concern for consumers. Although pyrethroid pesticides are low in toxicity, they are cumulative. The symptoms of poisoning are neurological symptoms and skin irritation. Therefore, the detection of pyrethroid pesticides cannot be ignored. The test paper to detect pyrethroid residues in fruit juice is a relatively simple and quick preliminary detection method. Common test paper types include immunochromatographic test paper and chemical colorimetric test paper. Immunochromatographic test paper uses the specific binding of antibodies and antigens. To detect pyrethroid residues, chemical colorimetric test paper indicates the presence of pyrethroids by producing color changes through specific chemical reactions. Test paper detection of pyrethroid residues in fruit juice is a common detection method. However, in actual applications, there are problems with low detection efficiency and slow operation process. In the fruit wholesale market, a large number of fruit batches need to be tested, and most of them use test paper detection. Due to its slow operation process and low detection efficiency, the fruit stays in the market for a longer time, which increases the storage cost. The fruit needs to occupy more storage space, and manpower is also required for management and maintenance. In order to solve this problem, it is urgent to develop a pyrethroid residue detection device. Utility Model Content
