1. Save the scene. The phytotoxicity of pesticides will be manifested in the crops with obvious increase. The crops where the phytotoxicity occurs are the sites of phytotoxicity. In the case of phytotoxicity, the site should be protected as much as possible to avoid human and other aspects. Destruction, can not wait for the phytotoxicity scene to disappear naturally, otherwise, it will bring certain troubles to the identification work. Therefore, the phytotoxicity site is the basis of the identification work. In one year, some farmers in southern Fujian used phoxim produced in a factory in Jiangsu Province to control the cotton bollworm on peppers, causing a large-scale reduction of pepper production. However, the farmers found the relevant departments to request identification after the pepper was pulled out, and suffered from the lack of on-site identification. Also failed to do so.
If it is impossible to save the scene due to objective reasons, the phytotoxicity may be recorded by means of photographing, photographing, etc., but it is best that all parties are present at the time and notarized by the notary public. It should be pointed out here that the information on the occurrence of phytotoxicity recorded by the relevant equipment and equipment is not intuitive at the time of the identification, and sometimes the phytotoxicity is not completely reflected due to technical problems, and the identification work belt will be picked up. It must be difficult.
2. Collect relevant evidence for the pesticides used. The first is evidence of the purchase of pesticides, such as invoices, receipts, etc. Without these notes, the pesticide operator may not recognize that the pesticide you are using was purchased from him. The second type is the pesticides and pesticide packages (pesticide bottles and pesticide bags) remaining after use. If these things are preserved, it is basically indicated that the phytotoxicity of the crops in your field may be due to the use of such pesticides. If there is no evidence or evidence incomplete, the identification of the drug will bring great difficulties.
3. Please ask the relevant departments for identification. At present, there is no authoritative drug damage identification department. The author believes that the agricultural technology research, teaching and extension management department should be the main body of drug damage identification. In the end, please ask the specific department, which should be recognized by pesticide users, operators and producers. Department. Only in this way, the reasonable solution made by the appraisal department will be accepted by all parties in the shortest time, which is conducive to the early resolution of the drug accident.
