Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard instead of GB/T 20684-2006 "glyphosate water agent", compared with GB/T 20684-2006, in addition to editorial changes the 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;

- Formaldehyde control index is not more than 10g/kg revised to not more than 0.6g/kg;

--- increase the nitrite glyphosate control index and the corresponding analysis method.

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).
