  1. There are many net celebrities, and pesticide residues are plagued by diseases!

It’s an Internet celebrity, naturally there are many right and wrong. In recent years, the biggest problem of wolfberry exports has always been the problem of pesticide residues. Due to the characteristics of wolfberry, the prevention and control of wolfberry diseases and insect pests is mainly based on pesticides. In 2014, the Chinese Academy of Medical Sciences Institute of Medicinal Botany Xu Changqing, Chen Jun and other big coffees made statistics on the “preferences” of pesticide use in China’s major wolfberry producing areas. Ningxia grows wolfberry It is not uncommon to use pesticides 9-10 times a year. Xinjiang uses pesticides 8-11 times a year for planting wolfberry, and Qinghai uses pesticides the least for growing wolfberry, and it also needs to use pesticides 3-6 times a year.

  1. There are two types of pesticide residues in exported wolfberry
  2. The problem of old pesticide residues-the problem is low-level, the problem always occurs!

The problem of old pesticide residues is mainly the 33 pesticide residues that are prohibited in the 2020 Chinese Pharmacopoeia “General Rules for the Verification of Medicinal Materials and Decoction Pieces”, such as: BHC, DDT (DDT) and other more toxic pesticide residues. Some pesticides have even been used in my country. Production and sales are banned. After domestic management has become stricter and exports have been returned time and time again, companies that export wolfberry have a better and better memory, and the occurrence of such low-level pesticide residue errors has been significantly reduced.

However, the problem of old pesticide residues also means “problems that always arise”! Carbofuran has been detected by Europe and the United States in the past two years, and is often on the list.
