Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 22616-2008 "Fenoxaprop-p-ethyl Technical", GB/T 22617-2008 "Fenoxaprop-p-ethyl Aqueous Emulsion" and

GB/T 22618-2008 "Fenoxaprop-ethyl EC", and GB/T 22616-2008, GB/T 22617-2008, GB/T 22618-2008 In comparison, the main technical changes are as follows.

---Modified the quality score index of fenoxaprop-p-ethyl technical; added 10% specifications to fenoxaprop-p-ethyl aqueous emulsion and emulsifiable concentrate (see 4.2; GB/T 22616-2008 version 3.2, GB/T 22617-2008 version 3.2, GB/T 22618-2008 version 3.2).

---The R-enantiomeric ratio control item was added to the water emulsion and emulsifiable concentrate of fenoxaprop-p-ethyl Ethoxylin; Fenoxaprop-p-ethyl EC increases the long-lasting foaming control item; the R-enantiomer ratio is increased in the heat storage stability test Examples and pH measurement items (see 4.2, 3.2, 4.9 of GB/T 22617-2008 edition, 3.2, GB/T 22618-2008 edition 4.8).

---Modified the determination method of fenoxaprop-p-ethyl (see 5.4, 5.5, 5.6; GB/T 22616-2008 version 4.3.2, 4.3.1, Appendix A,

GB/T 22617-2008 version 4.3.2, 4.3.1, Appendix A, GB/T 22618-2008 version 4.3.2, 4.3.1, Appendix A).

---Change the acceptance period of 1 month for Fenoxaprop-p-ethyl technical to 2 years of quality assurance period (see 6.2, GB/T 22616-2008 version 5.

6).
