1 Scope

GB/T 17980.15-2026 is the Chinese national standard covering the trial protocol for aphid control in field crops - where the damage that matters is usually the virus the aphid carries rather than the feeding, so speed of kill counts for more than persistence. The GB/T 17980 series is what a pesticide registration in China rests on: it fixes the plot design and replication, the application rate and timing, the assessment of the pest, disease or weed and of the crop, and the analysis of the result. It replaces GB/T 17980.15-2000 and has been in force since 1 September 2026. It was issued on 27 February 2026 and has been in force since 1 September 2026, replacing GB/T 17980.15-2000. The document is under the responsibility of the Ministry of Agriculture and Rural Affairs. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes the methods for field plot efficacy tests of insecticides for controlling aphids on crops such as potatoes. This document applies to the use of insecticides to control wingless aphids on crops such as potatoes (excluding seed potatoes), beets, peas, and broad beans, including the bean aphid. The verification shall be carried out in accordance with the reference.

4 Test conditions

4.1 Test subjects and crops The experimental subject was aphids. The species of aphids were recorded. The experimental crops included potatoes (excluding seed potatoes), sugar beets, peas, and broad beans. The names of the crops and varieties were recorded.

4.2 Environmental Conditions The experimental sites were selected from representative fields with moderate aphid infestations. All experimental plots used the same crop varieties and cultivation conditions (soil type, fertilizer) as specified. The feed, cultivation, and plant spacing should be uniform and consistent, and conform to local scientific agricultural practices.

5 Experimental Design and Arrangement

5.1 Test Treatment The following treatments should be set up. test reagent, control reagent, and blank control.

6 Applying pesticides

6.1 Application Method Perform the application according to the test requirements and label instructions. The application method should be adapted to local scientific agricultural practices. Record the application method and procedures. process.

6.2 Application equipment Select commonly used equipment, or select equipment according to the test requirements. Record the type of equipment used and the operating conditions (e.g., working pressure, nozzle type). Information such as type and nozzle diameter, etc.

6.3 Application time and frequency Follow the test requirements and label instructions. Spraying is recommended at the early stage of wingless aphid infestation; seed (seed potato) treatment is recommended after crop sowing. Pre-application. Record the number of applications, the date of each application, and the crop growth stage.

6.4 Dosage Administer the medication according to the test requirements and the dosage specified on the label. Record the prepared dosage and the amount of active ingredient used. The prepared dosage is usually expressed in mL/667m^2 (milliliters). The dosage is expressed in liters per 667 square meters (g/667m2) or g/667m2 (grams per 667 square meters), while the dosage of the active ingredient is expressed in g/hm2 (grams per hectare). Used for When spraying pesticides, record the amount of pesticide solution used per hectare, expressed in L/hm2 (liters per hectare). Application should ensure accurate dosage and even distribution. Uniformity is required. Dosage deviation should not exceed ±10%. If it exceeds ±10%, it should be recorded and its impact assessed.

6.5 Chemical requirements for controlling other diseases, pests, and weeds If other pesticides are used to control pests, diseases, and weeds other than the test subjects during the experiment, those that have no effect on the test pesticides or test subjects should be selected. The reagents were used separately from the test and control reagents, and all plots were treated uniformly to minimize interference from these reagents. Extent. Record accurate information about the application of this type of medication (such as the generic name of the medication, dosage form, content of active ingredient, dosage, method of application, and application method). (Time, target of prevention and control, etc.)

8 Methods for calculating drug efficacy

8.1 Insect population decline rate The insect population reduction rate is calculated according to formula (1).

8.2 Prevention and control effect The control effect of spray treatment is calculated according to formula (2) or formula (3), and the control effect of seed (seed potato) treatment is calculated according to formula (4).

8.3 Statistical Analysis Appropriate biostatistical methods (such as Duncan's new multiple range method or other multiple comparison methods) should be applied to analyze the results and determine the significance of differences. Compare the sexes and indicate the statistical analysis software used.

9 Results and Report Writing

Based on the experimental results and statistical analysis, the product characteristics, efficacy, safety, and key usage techniques were evaluated, and an experimental report was compiled. The report should include a summary table of the original data. GB/T 17980.15-2026. Guidelines for Field Efficacy Trials of Pesticides Part 15.
