1 Scope

GB/T 17980.10-2026 is the Chinese national standard covering the trial protocol against pear psylla - an insect that is difficult to reach in the honeydew it produces, and that has developed resistance to most of what has been used on it. 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 17980.10-2000 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 17980.10-2000. 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 pear psyllids. This document applies to field plot efficacy trials and efficacy evaluations for the registration of insecticides for controlling pear psyllachinensis. The price and efficacy of other pear psyllids in field trials should be followed.

4 Test conditions

4.1 Test subjects and crops The test subject was the pear psyllid. The experimental crop is the pear tree, and it is advisable to select a locally cultivated variety. Record the variety name.

4.2 Environmental Conditions The experimental sites should be selected from representative orchards with moderate to severe pear psyllid infestation. The crop varieties and cultivation conditions of all experimental plots should be... The conditions (such as soil type, fertilizer and water, tree age, and row and plant spacing) 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 should be adapted to local scientific agricultural practices. 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. It is advisable to apply the pesticide during the initial peak hatching period of pear psyllid eggs (around 30% hatching rate). Record the number of applications. Number of applications, date of each application, and crop growth period.

6.4 Dosage Administer the medication according to the test requirements and the dosage specified on the label. Record the dosage of the active ingredient, usually expressed in mg/kg (milligrams per kilogram). For use When spraying, record the dilution ratio and the amount of pesticide solution used per hectare, expressed in L/hm2 (liters per hectare). Ensure proper spraying. Ensure accurate dosage and uniform distribution of medication. 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 Insect population decline rate The insect population decline rate is calculated according to formula (1).

8.2 Prevention and control effect The prevention and control effect is calculated according to formula (2) or formula (3).

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 17980.10-2026. Guidelines for Field Efficacy Trials of Pesticides Part 10. Insecticides for the Control of Pear Psyllids ICS
