Description

Technical Field

[0001] The present invention belongs to the technical field of pesticide query, and specifically relates to a method and system for screening pesticides applicable to green agricultural products, aiming to ensure the compliance of pesticide use in the production process of green agricultural products, while meeting the strict requirements of green agricultural products on pesticide residues. Background Art

[0002] As consumers become more aware of food safety and environmental protection, the market demand for green agricultural products is growing. Green food refers to safe, high-quality edible agricultural products and related products that are produced in a good ecological environment, produced in accordance with green food standards, subject to full quality control, and have obtained the right to use the green food logo. The current use of pesticides in the agricultural technology promotion system is based on national mandatory standards, and a green food production technology promotion system has not yet been established. Green food managers and producers lack the technology for pesticides suitable for green food production. In the existing technology, pesticide screening and use often rely on experience judgment, and lack scientific and systematic screening methods and standards. The types of pesticides used for green food crops have a great impact on the pesticide residues in agricultural products, and the problem of pesticide residues has always been a key factor affecting the quality of green agricultural products. Therefore, it is particularly important to develop a method and system for accurately screening pesticides that meet the residue limit requirements of green agricultural products and determine a reasonable safety interval. Specifically, which pesticide is suitable for each green agricultural product to ensure that the pesticide residue is lower than the standard is a problem that is difficult for ordinary agricultural technology extension personnel and ordinary growers to know.

[0003] Based on this situation, a method and system for screening pesticides applicable to green agricultural products were designed to facilitate agricultural technology promotion departments and growers to quickly learn about the applicable pesticides for green agricultural products. Summary of the invention

[0004] In order to overcome the above technical problems, the present invention provides a method and system for screening pesticides applicable to green agricultural products.

[0005] The present invention adopts the following technical solutions:

[0006] Green agricultural products are suitable for pesticide screening methods, including the following:

[0008] Match the name of the green agricultural product applicable to the pesticide to be queried with the applicable standard catalog of green food products, and search for the name of the crop corresponding to the green agricultural product in the applicable standard catalog of green food products;

[0009] S2. Preliminary selection of applicable pesticides

[0010] According to the matched crop name, the registered pesticides applicable to the crop are preliminarily queried from the national pesticide registration database. The pesticides have clear registration numbers and related information;

[0011] S3. Comparison of active ingredients of pesticides

[0012] Compare all active ingredients of registered pesticides found with the Guidelines for the Use of Green Food Pesticides NY / T393, check whether the active ingredients of each pesticide are within the permitted use range specified in the guidelines, and eliminate pesticides that do not meet the requirements of the guidelines;

[0013] S4. Query residue limit value

[0014] For pesticides that meet the requirements of the guidelines, further query their residue limit values ​​in the national mandatory standard library and the green food industry recommended standard library, take the minimum value of the two, eliminate pesticides with any active ingredient residue limit not exceeding 0.1 mg / kg, and screen out pesticides with active ingredient residue limit values ​​exceeding 0.1 mg / kg;

[0015] S5. Determine the applicable pesticide

[0016] When the residue limit values ​​of all active ingredients of the selected registered pesticide exceed 0.1 mg / kg, it can be determined that the pesticide is suitable for the production of the green agricultural product.

[0017] Green agricultural products are suitable for pesticide screening systems, including:

[0018] An input module is used for the user to input the name of the agricultural product for which the user wants to query the applicable pesticide into the system;

[0019] Agricultural product name matching module, used to find the canonical product name corresponding to the input name;

[0020] The pesticide preliminary selection module is used to preliminarily query the pesticides suitable for the crop;

[0021] The active ingredient comparison module has built-in criteria, which is used to compare the active ingredients of the pesticides initially queried with the criteria, check whether each active ingredient is within the permitted use range specified in the criteria, and eliminate pesticides that do not meet the criteria requirements;

[0022] The residue limit comparison module further queries the residue limit values ​​of pesticides that meet the requirements of the guidelines and screens out pesticides whose residue limit values ​​of active ingredients exceed 0.1 mg / kg;

[0023] The output module is used to output the name of the applicable pesticide finally determined.

[0024] Preferably, the agricultural product name matching module has a built-in green food product applicable standard catalogue, and matches standardized product names from the green food product applicable standard catalogue.

[0025] Preferably, the pesticide preliminary selection module has a built-in national pesticide registration database, and preliminary selects applicable registered pesticides from the national pesticide registration database.

[0026] Preferably, the guidelines are green food pesticide use guidelines.

[0027] Preferably, the reference for comparison of residue limit values ​​is the national mandatory standard library and the green food industry recommended standard library.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The screening system of the present invention is provided with an input module, which is used for a user to input the name of the agricultural product for which the user wants to query the applicable pesticide into the system; an agricultural product name matching module is provided to search for the standardized product name corresponding to the input name; a pesticide preliminary selection module is provided to preliminarily query the pesticide applicable to the crop; an effective component comparison module is provided, which has a built-in criterion to compare the effective components of the pesticide preliminarily queried with the criterion, to check whether each effective component is within the permitted use range specified in the criterion one by one and to eliminate the pesticide not meeting the criterion requirement; a residue limit value comparison module is provided to further query the residue limit value of the pesticide meeting the criterion requirement, and to screen out the pesticide with the residue limit value exceeding 0.1 mg / kg; an output module is provided to output the name of the applicable pesticide finally determined; the grower only needs to input the name of the green agricultural product into the system, and the system can provide the appropriate pesticide, which can facilitate the agricultural technology promotion department and the grower to quickly query the applicable pesticide of the green agricultural product planted.
