[0067] The present application is described below in conjunction with the drawings in the present application.

[0068] Embodiment 1: Figures 1 to 3 As shown, a method for evaluating the efficacy of a compound pesticide preparation in the field of the present invention specifically comprises the following steps:

[0069] S1, dividing the pesticide application field into a number of pesticide application units according to a preset division strategy;

[0070] The method for setting the partitioning strategy includes:

[0071] Identify the types of crops planted in the fields where pesticides are applied. Different crops have different absorption, transport and metabolism mechanisms for pesticides, which will affect the efficacy of the pesticides.

[0072] The growth stage of crops will also affect the efficacy of pesticides; crops have different sensitivities and requirements for pesticides at different stages, such as the seedling stage, growth stage, flowering stage, and fruiting stage;

[0073] Identify the types of diseases in the field. Different types of diseases respond differently to pesticides. Understanding the types of pathogens, infection methods, and degree of damage will help select appropriate pesticides and develop targeted application strategies.

[0074] Obtain field size specifications, including field area, shape, topography, etc.;

[0075] Crop species are quantified using coding methods, with each crop being assigned a unique identifier or category code;

[0076] According to the growth cycle of crops, the growth stage is divided into several sub-stages, and a numerical value or grade is assigned to each sub-stage;

[0077] Code the disease type and assign a unique identifier to each disease; also quantify the severity or damage level of the disease;

[0078] Integrate the quantified crop types, growth stages and disease type information to construct the field crop growth status vector;

[0079] A farmland unit division model is constructed based on historical data and machine learning algorithms; the model can automatically divide reasonable pesticide application units according to the input field crop growth state vector and field size specifications;

[0080] Input the constructed field crop growth state vector and field size specifications into the pre-trained farmland unit division model;

[0081] Based on the input information, the model outputs a partitioning strategy, including the number, location, size and shape of the application units; this partitioning strategy aims to ensure that the crop growth status and disease conditions within each application unit are relatively consistent, thereby facilitating subsequent efficacy evaluation.

[0082] In this step, by clarifying the crop types, growth stages and disease types in the pesticide application field and quantifying them, a model that accurately reflects the growth state vector of field crops can be constructed; the field crop growth state vector comprehensively considers the sensitivity and demand of crops to pesticides and the response of diseases to pesticides, so as to more accurately evaluate the actual efficacy of compound pesticides under field conditions; using a pre-trained farmland unit division model, reasonable pesticide application units can be automatically divided according to the field crop growth state vector and field size specifications; ensuring that the crop growth state and disease conditions in each pesticide application unit are relatively consistent, reducing the efficacy evaluation error caused by crop growth differences and uneven disease distribution; through automated and intelligent division strategies, it can greatly improve Improve the efficiency of efficacy evaluation; compared with the traditional manual division method, this method is more objective, accurate and easy to implement; at the same time, the output of the division strategy also facilitates the subsequent application operation and efficacy data collection; after understanding the crop types, growth stages and disease types in the field, it is possible to select suitable pesticides and formulate application strategies in a more targeted manner; it helps to reduce the amount of pesticides used, reduce environmental pollution, and improve the prevention and control effect; this step clarifies key information such as crop types, growth stages and disease types, and adopts quantitative processing and intelligent division strategies to provide a solid foundation for the subsequent field efficacy evaluation of compound pesticide preparations; this not only improves the accuracy and efficiency of efficacy evaluation, but also promotes the development of agriculture in a more scientific and environmentally friendly direction.

[0083] S2, obtaining the efficacy value of each pesticide application unit, and assigning values ​​based on the position of the pesticide application unit in the field to obtain a pesticide application field efficacy matrix; the efficacy value is the disease density of the pesticide application unit before the pesticide application minus the disease density of the pesticide application unit after the preset duration of the pesticide application;

[0084] The method for obtaining the efficacy matrix of pesticide application in the field comprises:

[0085] Before applying pesticides, measure the disease density of each application unit to obtain the disease density of the application unit before applying pesticides; randomly select a number of sample points in each application unit and record the disease density of each sample point;

[0086] Apply pesticides to each application unit according to the predetermined compound pesticide formula and application method; record key information such as application time, dosage, and method;

[0087] After a preset time period after the application of pesticides, the disease density of each application unit is surveyed again to obtain the disease density of the application unit after the preset time period of the application of pesticides;

[0088] The efficacy value is obtained by subtracting the disease density of the application unit after the preset application time from the disease density of the application unit before application.

[0089] According to the division strategy of the pesticide application field, determine the number of rows and columns of the matrix;

[0090] Assign the efficacy value of each application unit to the corresponding element in the matrix; usually, each row of the matrix represents a drug application unit, and each column represents different efficacy value information, so as to obtain the drug efficacy matrix of the application field;

[0091] When constructing the matrix, some outliers may be encountered; these outliers may be caused by survey errors, uneven application of pesticides or other factors; these outliers should be reviewed and handled, such as re-survey, elimination or special marking.

[0092] In this step, by accurately measuring the disease density of each application unit before and after application, the efficacy value of each application unit can be accurately calculated; it is more comprehensive and accurate than traditional single disease density changes or crop growth indicators, and can more truly reflect the actual efficacy of compound pesticides under field conditions; the acquisition of efficacy values ​​is not only based on changes in disease density, but also combined with the location information of the application unit in the field; it is helpful to analyze the impact of different positions on efficacy, so as to more comprehensively evaluate the effect of compound pesticides; the efficacy value of each application unit is assigned to the corresponding element in the matrix, and the field efficacy matrix of application is constructed; the matrix representation makes the efficacy data more intuitive and easy to analyze, which helps to discover the spatial distribution law of efficacy and potential problem areas; when constructing the matrix, possible abnormal values ​​are reviewed and processed; it can ensure the accuracy and reliability of efficacy data and avoid misleading conclusions caused by survey errors, uneven application of pesticides and other factors.

[0093] S3, uniformly counting the efficacy matrix of the applied pesticide field, obtaining the average efficacy value of the compound pesticide, and correcting the average efficacy value of the compound pesticide by taking into account the application method; the application method includes spraying, irrigation and broadcasting;

[0094] The method for correcting the uniform value of compound pesticide efficacy includes:

[0095] Extract the efficacy value of each application unit from the field efficacy matrix; these efficacy values ​​reflect the changes in disease density before and after application of the application unit and are the direct basis for evaluating efficacy;

[0096] The extracted efficacy values ​​are evenly counted, that is, the average efficacy values ​​of all application units are calculated to obtain an average value that can represent the efficacy level of the entire field; this helps to eliminate the efficacy differences caused by special conditions in individual application units, thereby more accurately reflecting the overall performance of compound pesticides in the field;

[0097] According to the actual application operation, the application methods are divided into spraying, irrigation and broadcasting; different application methods have different effects on the efficacy of the medicine;

[0098] For each application method, a drug efficacy correction coefficient is determined based on existing research or experimental data; this coefficient reflects the potential impact of different application methods on drug efficacy and is used to correct the drug efficacy uniformity value;

[0099] The efficacy correction coefficient is applied to the efficacy uniform value to obtain the corrected efficacy uniform value; this value more accurately reflects the overall efficacy performance of the compound pesticide in the field after considering differences in application methods.

[0100] In this step, by calculating the average value of the efficacy values ​​of all application units, a uniform value that can represent the efficacy level of the entire field is obtained; this helps to eliminate the efficacy differences caused by special conditions in individual application units, thereby more comprehensively reflecting the overall performance of compound pesticides in the field; the calculation of the uniform value eliminates the influence of local outliers, avoids misleading the overall efficacy evaluation due to the special conditions of individual application units, and improves the accuracy and reliability of the evaluation results; according to the influence of different application methods on the efficacy, a correction coefficient is introduced to correct the uniform value of the efficacy; this makes the evaluation results closer to the actual application situation and improves the scientificity of the evaluation. The correction coefficient is determined based on existing research or experimental data, ensuring the scientificity and rationality of the correction process. By considering the impact of application methods on efficacy, it can provide scientific application suggestions for farmers and agricultural technicians, helping them to choose the most appropriate application method and improve the prevention and control effect. The corrected efficacy uniformity value is a quantitative indicator, which provides specific data support for agricultural management and decision-making, and helps to formulate more effective pest and disease control plans. S3 can not only more accurately evaluate the actual efficacy of compound pesticides under field conditions, but also provide scientific support for optimizing application strategies, reducing pesticide use and protecting the environment.

[0101] S4, feature recognition is performed on the efficacy matrix of the applied field, the efficacy characteristic value of the compound pesticide is obtained, and the relative relationship between the application time node and the disease onset period is considered to correct the efficacy characteristic value of the compound pesticide;

[0102] The method for correcting the characteristic value of compound pesticide efficacy includes:

[0103] Preprocess the efficacy matrix of the applied field, including data cleaning, missing value processing and outlier detection, to ensure the accuracy and reliability of the data;

[0104] Extract key features from the efficacy matrix, including the maximum, minimum, average, standard deviation and spatial distribution characteristics of the efficacy value; these features can reflect the efficacy performance and differences of compound pesticides in different application units;

[0105] According to actual needs and evaluation objectives, the characteristics that have an important impact on the efficacy evaluation are selected as the efficacy characteristic values; the selected characteristic values ​​can fully and accurately reflect the efficacy characteristics of compound pesticides in field applications;

[0106] Clarify the relative relationship between the application time and the disease onset period; the disease onset period includes the initial stage, peak stage and decline stage of the disease; by comparing the application time with the disease onset period, evaluate whether the application time is appropriate and whether it may affect the efficacy of the drug;

[0107] The temporal and spatial distribution of the extracted efficacy characteristic values ​​was analyzed to examine the changing trend of the efficacy characteristic values ​​between different application units and the fluctuations at different time points. By analyzing the temporal and spatial distribution of these characteristic values, the relationship between efficacy and application time and disease onset period can be further revealed.

[0108] According to the relative relationship between the time node of pesticide application and the disease onset period and the results of the spatiotemporal distribution analysis, the correction coefficient of the characteristic value of drug efficacy is determined; the correction coefficient of the characteristic value of drug efficacy is intended to reflect the degree of influence of the relative relationship between the time node of pesticide application and the disease onset period on the characteristic value of drug efficacy;

[0109] The determined efficacy characteristic value correction coefficient is applied to the extracted efficacy characteristic value for correction; this step aims to make the efficacy characteristic value more accurately reflect the actual efficacy of the compound pesticide in field application, while taking into account the relative relationship between the application time and the disease onset period.

[0110] In this step, the accuracy and reliability of the efficacy matrix data are ensured through data cleaning, missing value processing and outlier detection, laying a solid foundation for subsequent feature identification and analysis; the maximum, minimum, average, standard deviation and spatial distribution characteristics of the efficacy values ​​are extracted, which can comprehensively reflect the efficacy performance and differences of compound pesticides in different application units, and provide a multi-dimensional efficacy evaluation perspective; according to actual needs and evaluation objectives, the characteristics that have an important impact on the efficacy evaluation are selected as the efficacy characteristic values, ensuring the scientificity and practicality of the evaluation results; the relationship between the time node and the disease onset period: clarify the relative relationship between the application time node and the disease onset period, evaluate whether the application time is appropriate, and whether it may affect the efficacy; help optimize the application time and improve the prevention and control effect; by analyzing the efficacy characteristic values The changing trends among different application units and the fluctuations at different time points further reveal the relationship between efficacy and application time and disease onset period, providing a scientific basis for refined management; the efficacy characteristic value correction coefficient is determined according to the relative relationship between the application time node and the disease onset period and the results of spatiotemporal distribution analysis; it can more accurately reflect the influence of the application time node on the efficacy and improve the accuracy of the evaluation results; the determined efficacy characteristic value correction coefficient is applied to the extracted efficacy characteristic value for correction; the efficacy characteristic value is made to more accurately reflect the actual efficacy of compound pesticides in field applications, while taking into account the relative relationship between application time and disease onset period; the corrected efficacy characteristic value is a quantitative indicator, which provides specific data support for agricultural management and decision-making, and helps to formulate more effective pest and disease control plans.

[0111] S5, inputting the corrected compound pesticide efficacy average value and the corrected compound pesticide efficacy characteristic value into the compound pesticide efficacy evaluation model to obtain the compound pesticide field efficacy evaluation value;

[0112] The structure of the compound pesticide efficacy evaluation model includes:

[0113] Model input layer: used to receive the corrected compound pesticide efficacy uniformity and efficacy characteristic values; the input data represents the efficacy performance under different application units, different application methods and different application time nodes; the input layer converts these data into a format that can be processed by the model, providing a basis for subsequent calculations and analysis;

[0114] Data processing layer: used for further preprocessing and feature extraction of input data; this layer includes steps such as data normalization, standardization, and feature selection to ensure the quality and consistency of input data; feature extraction aims to extract features that have an important impact on drug efficacy evaluation from the original data to improve the prediction accuracy of the model;

[0115] Model core layer: used to evaluate the efficacy based on the input data; it uses a variety of algorithms and model structures, such as neural networks, support vector machines, decision trees, etc.; it can handle complex nonlinear relationships, so as to more accurately evaluate the actual efficacy of compound pesticides under field conditions; in the model core layer, a comprehensive efficacy evaluation value is calculated based on the input efficacy average value and efficacy characteristic value; this evaluation value is a comprehensive indicator that can fully reflect the efficacy performance of compound pesticides under different conditions;

[0116] Output layer: used to output the efficacy evaluation value calculated by the core layer of the model to the user; this layer includes functions such as result interpretation and visual display to help users better understand the evaluation results of the model; the results of the output layer are usually presented in the form of numerical values ​​or charts to facilitate users' subsequent analysis and decision-making.

[0117] In this step, by comprehensively considering the efficacy performance under different application units, different application methods and different application time nodes, the model can more comprehensively reflect the actual efficacy of compound pesticides under field conditions; the core layer of the model adopts a variety of algorithms and model structures, such as neural networks, support vector machines, decision trees, etc., which can handle complex nonlinear relationships, thereby improving the accuracy of efficacy evaluation; the data processing layer further preprocesses and extracts features of the input data, ensuring the quality and consistency of the input data and providing reliable input for the model; through feature extraction, features that have an important impact on efficacy evaluation are extracted from the original data, further improving the prediction accuracy of the model; the output layer provides result interpretation and visualization display functions, so that users can more easily understand the evaluation results of the model; the output results in numerical and graphical forms facilitate users to conduct subsequent analysis and decision-making, improving the practicality and user-friendliness of the model; the entire evaluation process is based on mathematical models and algorithms, avoiding the interference of human factors and ensuring the scientificity and objectivity of the evaluation results; the application of the model provides a scientific, objective and accurate method for the efficacy evaluation of compound pesticides, which helps to promote the research and development and application of pesticide formulations.

[0118] S6. Based on the preset threshold of the compound pesticide, a qualified judgment is made on the field efficacy evaluation value of the compound pesticide;

[0119] The calculated efficacy evaluation value is compared with the preset efficacy threshold; if the efficacy evaluation value is higher than or equal to the threshold, it is considered that the efficacy of the compound pesticide in field application is qualified; if the efficacy evaluation value is lower than the threshold, it is judged to be unqualified;

[0120] For qualified compound pesticides, further analyze the advantages and disadvantages of their efficacy performance to provide guidance for subsequent pesticide research and development and application;

[0121] For compound pesticides that are judged as unqualified, we will conduct in-depth analysis on the reasons for their poor efficacy, which include improper application methods, unreasonable application time nodes, and poor synergy between pesticide components, and propose improvement measures for these problems; adjust and optimize the formula, application method, application time nodes, etc. of compound pesticides to improve their efficacy and reduce adverse effects on the environment and crops;

[0122] The factors affecting the setting of the preset threshold of the compound pesticide include:

[0123] Physicochemical properties of pesticides: The chemical composition, physicochemical properties and mechanism of action of pesticides directly affect their efficacy. For example, some pesticides may be effective against specific pests or diseases, but ineffective against other pests and diseases. Therefore, when setting thresholds, it is necessary to consider the specific composition and mode of action of the pesticides. The toxicity of pesticides is also an important factor to be considered when setting thresholds. Highly toxic pesticides require lower thresholds to ensure safe use. At the same time, the residues of pesticides in the environment and their impact on the ecosystem also need to be considered.

[0124] Types and characteristics of pests and diseases: Different pests and diseases have different living habits, development stages and resistance levels; therefore, when setting thresholds, it is necessary to consider the specific types and characteristics of pests and diseases, as well as their sensitivity to pesticides; for pests and diseases that cause serious harm, higher prevention and control standards need to be set to ensure the safety of agricultural production;

[0125] Application method: Different application methods will affect the coverage and uniformity of pesticides, thus affecting the efficacy; therefore, when setting the threshold, it is necessary to consider the specific conditions of the application method and its impact on the efficacy;

[0126] Application time: The application time is closely related to the onset period of pests and diseases. Applying pesticides at the peak of pests and diseases can achieve better control effects. Therefore, when setting the threshold, the relative relationship between the application time and the onset period of pests and diseases needs to be considered.

[0127] Environmental factors: Environmental factors such as temperature, humidity, light, and soil properties can affect the efficacy of pesticides. For example, herbicides may be less effective under drought conditions. Therefore, when setting thresholds, local climate conditions and soil conditions need to be considered.

[0128] Crop types: Different crops have different sensitivities and tolerances to pesticides. At the same time, crops have different requirements for pesticides at different growth stages.

[0140] The system uses mathematical models and statistical analysis methods to evaluate the efficacy, avoiding the subjectivity of human judgment and improving the scientific nature of the evaluation. The efficacy evaluation module uses the compound pesticide efficacy evaluation model to calculate by inputting the corrected efficacy average value and efficacy characteristic value to obtain an objective and accurate efficacy evaluation value.

[0141] The modules of the system have clear logic and are interrelated, making them easy to operate and implement. The system can provide reliable efficacy evaluation results for agricultural production, guide farmers to use compound pesticides scientifically and rationally, and improve agricultural production efficiency and agricultural product quality.
