Every one Focus on quality and safety problems of goji berries, because consumers are very concerned about pesticide residues. Since 2003, Zhang Rong led the team to carry out a national science and technology research projects, this project is called the safe use of pesticides and insect pests technical platform of goji berry.
After ten years, until 2014, 29 kinds of chemical pesticides and agricultural risk assessment all out. The following is the urgent need to introduce pesticide maximum residue limits.
Why set standards? Zhang Rong explained, there is no excessive goji berry pesticide residues in the law, batches of goji berry exports encountered pesticide residues’ technical barriers’ and was returned, this become China’s exports of goji berry and domestic food safety supervision of the short board. Therefore, in order to promote the healthy development of goji berry industry and improve the international competitiveness of goji berry products, it is urgent to study and formulate the national standards for pesticide residues in Lycium barbarum fruit.”
To this end, Zhang Rong led the team to do a lot of work. In 2016 she drafted a standard draft and preparation instructions, in late October the formation of “pesticide goji berry fruit MRLs” local food safety standards draft, has been submitted to the Ministry of Agriculture approved and issued.[/fusion_text][/one_full][one_full last=”yes” spacing=”yes” center_content=”no” hide_on_mobile=”no” background_color=”” background_image=”” background_repeat=”no-repeat” background_position=”left top” hover_type=”none” link=”” border_position=”all” border_size=”0px” border_color=”” border_style=”” padding=”” margin_top=”” margin_bottom=”” animation_type=”” animation_direction=”” animation_speed=”0.1″ animation_offset=”” class=”” id=””][fusion_text]“Now we are very concerned about organic goji berry, which is a good thing, but it is easy to occur pests, if the control is not good, will suffer losses.” Zhang Rong cited an example, she said, Ningxia Dadi ecological Co., Ltd. in 2013 to build a base in Ningxia goji berry, the first year there is no fruit, so no pests. The spring of 2014, we look to the base, has been found goji berry mite disease, to remind the enterprises must fight pesticides, otherwise once the outbreak of a large area and it is difficult to control pesticide. But our proposal did not get enough attention, missed the April key control period, to the end of May, and the outbreak of gall mite. At this time the enterprise worried, but unfortunately missed the best timing. That year, Dadi’s Goji berry basically all diseases. They regret not using our plan in the early stages. Enterprises suffered heavy losses. Since then, they have been very active and the general manager has said, ‘I’ll listen to you.’. Last year, we seize the critical period of disease prevention and control, scientific medication, as a result, the high yield of goji berry, good quality. Now enterprises are very recognized.”
Turning to the future direction of the prevention and control of diseases and insect pests in China, Zhang Rong said a new word: ecological regulation”. She said, “whether you control what way, they cannot do without pesticides, but must make use of biological diversity, ecological regulation, that is to say, first the pest control, and then use the biological pesticide way of putting it steady. At present, Dadi has opened up 150 acres of land for the ‘ecological control’ test. From the beginning of last year to do identification, then according to the different varieties and different proportion of planted some plants, the goji berry and red dates, Apple’s implementation of interplanting, completed a suitable crop control region, through a year of observation, we found that the test area and incidence of diseases is very small, it is pest the harm of natural enemies in a hurry up. This technology is still in the practice phase, I hope that two years later, out of a technical parameter, do a model, and then conduct a comprehensive promotion, so that goji berry completely out of pesticides……”
