Introduction

Field efficacy trials are an important means of evaluating the comprehensive efficacy of pesticides against pests under various environmental factors, and are crucial for guiding pesticide safety. It provides crucial technical basis for the comprehensive and rational use of pesticides. It helps to scientifically evaluate the efficacy and safety of pesticides and reduce discrepancies in results caused by different testing methods. There is a need to standardize the procedures and evaluation content for field efficacy trials. GB/T 17980 describes insecticides, fungicides, herbicides, and plant pesticides. A total of 149 field efficacy test methods for plant growth regulators and other pesticides against their respective target pests were established, aiming to standardize methods, unify evaluation criteria, and promote pesticide production. The research, development, registration and use of the product are planned to consist of 149 parts, as detailed in Appendix A. Guidelines for Pesticide Field Efficacy Trials Part 53.Herbicide Control of Weeds in Crop Rotation

1 Scope

This document describes the methods for field plot trials of herbicides for controlling weeds in crop rotation. This document applies to the registration of herbicides used for weed control before sowing of crop rotation, fallow land, and arable land with low field efficacy for pre-planting herbicides used in crop rotation, fallow land, and arable land with the previous crop. District testing and safety evaluation.

3 Terms and Definitions

This document does not contain any terms or definitions that need to be defined. 4.Test conditions 4.1 Selection of Crops and Cultivars The next crop in crop rotation should be a locally common cultivation type, selecting widely planted varieties. Seed quality should meet the requirements for field use. Please record the type of crop to be planted next (including its Chinese and Latin scientific names), cultivation type, and variety name. 4.2 Selection of weeds as test subjects The weeds in the test site should be representative, the weed density should meet the experimental requirements, and the weeds should be evenly distributed. The weed community composition should be the same as that of the test herbicide. The herbicide spectrum is consistent. Record the Chinese and Latin scientific names of various weeds. 4.3 Cultivation conditions Soil conditions (soil type, organic matter content, pH, moisture, fertility) and tillage practices for the next crop rotation should be consistent across all experimental plots. The planting should be uniform and consistent, and conform to local scientific agricultural practices. Cultivation measures such as seeding rate, sowing depth, and density (plant spacing, row spacing) for the next crop in crop rotation should be... It conforms to local production realities. Record the previous crop and the herbicides used in the previous crop, and avoid selecting plots that may affect the growth of the next crop or the effectiveness of the tested herbicides. 5.Experimental Design and Arrangement 5.1 Test Treatment Treatments such as experimental agents, control agents, manual weeding, and blank control should be set up. ...
