Introduction

GB/T 19337—2017 Standard Overview

GB/T 19337—2017 Abamectin EC is an important standard in the pesticide field of the People's Republic of China, which is used to regulate the quality requirements, test methods and storage and transportation conditions of Abamectin EC. This standard replaces the old version of the standard GB/T 19337—2003. The main technical changes include the clear provisions of the mass fraction of Abamectin, the optimization of the ratio of B₁a to B₁b, and the addition of a new persistent foaming control item.

Comparison of standard frameworks

Project dimensions	Old version of the standard (GB/T 19337—2003)	New version of the standard (GB/T 19337—2017)
Quality indicators	The specific value of the mass fraction of avermectin is not clear	The mass fraction of avermectin is stipulated as 1.8%, 3.2%, 5.0% and 10.0%
Ratio of B₁a to B₁b	Not less than 4.0	Not less than 10.0
Control Items	Persistent Foaming is Not Included	Added Persistent Foaming (≤60mL)

Technical Background and Evolution Analysis

Avermectin is a pesticide widely used to kill insects and mites. Its emulsifiable concentrate form is highly favored due to its high solubility and stability. The technical upgrade of the new version of the standard reflects the industry's higher requirements for product quality and safety:

Mass fraction: The technical indicators of products with different concentrations are clearly defined to ensure product consistency.
Optimization of the ratio of B₁a to B₁b: Higher ratio requirements improve product quality and stability.
Added Persistent Foaming Control: This reflects the focus on the performance of emulsifiable concentrate products to avoid excessive foam affecting the application effect.

Test methods and implementation suggestions

Optimized application of high performance liquid chromatography

The new standard recommends the use of high performance liquid chromatography (HPLC) for the quality analysis of avermectin. The specific operating conditions include:

Mobile phase ratio: methanol: acetonitrile: water = 45:40:15.
Detection wavelength: 245nm, suitable for ultraviolet detection of avermectin.
Chromatographic column requirements: C₁₈ filler, inner diameter 4.6mm, length 250mm.

Through case analysis, it was found that this method has the characteristics of good separation effect, high sensitivity and good repeatability, and is particularly suitable for the quality control of avermectin emulsifiable concentrate.

Implementation Suggestions

To ensure the effective implementation of the standard, it is recommended that:

Enterprises should be equipped with advanced analytical equipment and professional technical personnel.
Strictly control the quality and proportion of raw materials during the production process.
Regularly conduct low temperature stability, heat storage stability and emulsion stability tests to ensure the long-term consistency of product quality.
