Discussion on pesticide residue limits standards for green food pakchoi
In the supervision process of partial leaf vegetables with green certification,it was found that the residue limits of some pesticides exceeded the green standard too frequently.By interpreting the selection principle of permissible pesticide list for green food and the formulation method of pesticide residue index for green food,the reasons for the revocation of certification of green products pakchoi due to unqualified quality sampling were analyzed.After comparing and sorting out"Green food-Brassica rapa"(NY/T 654-2020)and"Green food-Leaf vegetables"(NY/T 743-2020),it was found that the current green standard had deviations in the classification and attribution of pesticide residues in green vegetables and some limit values were too strict,which could not meet the actual needs of production and supervision.It is recommended to merge and revise the above two standards into"Green food-Leaf vegetables",and the pesticidde types in the list of green pesticides should include at least two optional pesticides that can control the same crop and the same pest and disease in order to meet the needs of the production of pesticides for alternate use.
