Study on Export Litchi by Pesticide Residue Detector

<

The main large area planting of litchi is dominated by traditional agriculture, but in the normal production of fruit, in order to increase the yield, the dosage of chemicals and hormones and the use of fertilizers are increased, and the quality of litchi is reduced. Exports of foreign lychees will remain for a long time, because the quality and sales of this litchi is deadly, and pesticide residue problems affect the litchi of Chinese exports. A preliminary investigation was conducted on the determination of traditional organic litchi lychee and pesticide residue detectors.

Of the 10 samples analyzed by the Pesticide Residue Tester, no chemical pesticides were detected in the 5 samples collected in the organic litchi garden, whereas 1 to 2 pesticide residues were detected in the 5 samples of conventional litchi orchards. Residues of dicofol and methamidophos were detected. Methamidophos pesticide residues were high at 0.178 mg/kg. China's National Standard for the Limitation of Pesticide Residues in Fruits clearly specifies that methamidophos cannot be detected in fruits, and cypermethrin is also detected in other four conventional litchi gardens.

The litchi analysis results of the Pesticide Residue Tester showed that the pesticide residues in the litchi peel and the litchi pulp were higher than the pulp on the surface. The results of the Pesticide Residue Tester showed that the organic certification bodies produced pesticide residues in the litchi orchard orchards produced in accordance with conventional and non-certified litchi. Permethrin is a commonly used chemical insecticide for cyanide, and three routine sample orchards. All the investigations were detected.

For example, “green barriers” are known in the case of obstacles encountered in Guangdong litchi. To ensure the vitality of Lingnan's proper fruit market and make it popular with the help of the international market is a special advantage to promptly play the role and effect of the pesticide residue detector. For the benefit of growers, the development of organic lychee and the selection of a reliable certification authority certification litchi out of China's "green barrier", the only way to develop new markets.
