This document replaces GB/T 17980.1-2000 "Guidelines for Field Efficacy Testing of Pesticides (I) - Control of Lepidoptera Borers in Rice". Compared with GB/T 17980.1-2000, the main technical changes in "Pests" are as follows, except for structural adjustments and editorial modifications.

a) The scope of application has been changed (see Chapter 1, Chapter 1 of the.2000 edition);

b) The requirements for test subjects and crops have been changed (see 4.1,

2.1 of the.2000 edition);

c) The environmental conditions requirements have been changed (see 4.2,

2.2 of the.2000 edition);

d) Added provisions for test treatment (see 5.1);

e) The requirements for test and control reagents have been changed (see 5.2,

3.1 of the.2000 edition);

1 Scope

GB/T 17980.1-2026 is the Chinese national standard covering the trial protocol for an insecticide against rice stem borers - pests that spend their damaging stage inside the stem, so the assessment is of dead hearts and white heads rather than of the insects themselves. 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 and of the crop, and the analysis of the result, so that trials run by different institutes can be compared. It replaces GB/T 17980.1-2000 and has been in force since 1 September 2026, one of six 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 17980.1-2000. 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.

01 State Administration for Market Regulation The State Administration for Standardization issued a statement.

4 Test conditions

4.1 Test subjects and crops The subjects of the experiment were rice stem borer, rice stem borer, Taiwan rice stem borer, and rice bark borer. The experimental crop is rice, and it is advisable to select a locally cultivated variety. Record the variety name.

4.2 Environmental Conditions The experimental site should be a representative paddy field that has suffered severe damage over the years. All experimental plots should include specific crop varieties and cultivation conditions (such as soil type). The type, fertilizer, tillage, plant spacing, and water depth 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. Application methods should be adapted to local scientific agricultural practices. Record the application methods 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 nozzle diameter, etc.

6.3 Application time and frequency Conduct the test according to the requirements and label instructions. Application should be performed during the peak hatching period of insect eggs and into the 1st to 2nd instar larval stage. Record the number of applications and the amount of pesticide used. The date of application and the crop growth period.

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 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, content of the active ingredient, dosage, method of application, and administration). (Using time, target of prevention, etc.).

8 Methods for calculating drug efficacy

8.1 Victim Rate The damage rate is calculated using formula (1).

8.2 Prevention and control effect The plant (ear) protection effect and the insecticidal effect are calculated according to formula (2).

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 17980.1-2026. Guidelines for Field Efficacy Trials of Pesticides Part 1.
