GB 20686-2006Glyphosate water soluble powders (granules) (English PDF)

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).
