Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 20686-2006 "glyphosate soluble powder", compared with GB/T 20686-2006, in addition to editing
The main technical changes are as follows.
The glyphosate mass fraction is changed from the specified labeling value to the specified specific value;
- increase the corresponding cation control index and analysis method;
--- increase the nitrite glyphosate control index and the corresponding analysis method;
--- increase glyphosate soluble granules dust control indicators and the corresponding analysis method;
--- Eliminates pH control targets.
This standard is proposed by the China Petroleum and Chemical Industry Association.
This standard is nationalized by the National Pesticide Standardization Technical Committee (SAC/TC133).
