1 Scope

GB/T 17980.18-2026 is the Chinese national standard covering the trial protocol against striped flea beetle - a pest that eats the leaves as an adult and the roots as a larva, and that has become one of the hardest insects to control in Chinese vegetable growing. 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 or weed and of the crop, and the analysis of the result. It replaces GB/T 17980.18-2000 and has been in force since 1 September 2026, one of the parts of the series revised together. It was issued on 27 February 2026 and has been in force since 1 September 2026, replacing GB/T 17980.18-2000. 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 method for conducting field plot efficacy tests of insecticides for controlling the yellow-striped flea beetle on cruciferous vegetables. Record the efficacy trials and evaluations of field plots for the yellow-striped flea beetle. Field efficacy trials of other vegetables should follow the same guidelines.

4 Test conditions

4.1 Test subjects and crops The test subject was the yellow-striped flea beetle. Record the species of yellow-striped flea beetles. The experimental crop was a cruciferous vegetable. Record the crop and variety names.

4.2 Environmental Conditions The experimental sites should be representative fields with a moderate incidence of yellow-striped flea beetles. Crop varieties and cultivation conditions (soil) for all experimental plots should be specified. Soil type, fertilization, and tillage should be uniform and consistent, and conform to local scientific agricultural practices.

5 Experimental Design and Arrangement

5.1 Test Treatment Test reagents, control reagents, and blank controls should be included.

6 Applying pesticides

6.1 Application Method Follow the test requirements and label instructions. The application method should be adapted to local scientific agricultural practices, generally using spraying or spreading methods. Application of pesticides. When applying pesticides by spraying, spray from the perimeter of each area towards the center. Record the application method and procedure.

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 nozzle diameter, etc.

6.3 Application time and frequency Conduct the test according to the requirements and label instructions. Spraying should be done at the early stage of adult infestation by the yellow-striped flea beetle, when there are an average of 1 to 2 adults per plant. Apply pesticides at the appropriate time; broadcast application is best done before sowing or transplanting. Record the number of applications, the time 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/667m2. The dosage is expressed in milliliters per 667 square meters or g/667m^2 (grams per 667 square meters), and the effective ingredient dosage is expressed in g/hm^2 (grams per hectare). When applying pesticides by spraying, record the amount of pesticide solution used per hectare, expressed in L/hm2 (liters per hectare). Ensure accurate dosage and even distribution during application. 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 test plots were homogenized to minimize interference from these reagents. To a lesser extent. Record accurate information about the application of this type of medication (such as the generic name of the medication, dosage form, active ingredient content, dosage, method of application, and administration). (Using time, target of prevention, 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 spraying is calculated according to formula (2) or formula (3), and the control effect of spreading is calculated according to formula (4).

8.3 Statistical Analysis The results were analyzed and differences were statistically significant using appropriate biostatistical methods (such as Duncan's new multiple range method or other multiple comparison methods). Compare the significance of the data 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 17980.18-2026. Field Efficacy Testing Guidelines for Pesticides - Part 18.
