Abstract

Chemically stable, dry-flow, low compact, dust free, soluble granules of phosphoroamidothioate are prepared using a substantially dry granulation process including an agitative balling process. In a preferred embodiment, spherically shaped acephate granules are produces without the intentional addition of water and/or solvents.

       5 . The soluble granule of  claim 1 , further comprises 0.1-5.0 wt. % a dispersing agent.  
   
   
       6 . The soluble granule of  claim 1 , further comprises 0.01-0.08 wt. % an antifoaming agent.  
   
   
       7 . The soluble granule of  claim 1 , further comprises 0.01-10 wt. % a disintegrating agent.  
   
   
       8 . The soluble granule of  claim 1 , further comprises 0.01-1.0 wt. % a stabilizer.  
   
   
       9 . The soluble granule of  claim 1 , wherein said phosphoroamidothioate compound is acephate.  
   
   
       10 . The soluble granule of  claim 1 , further comprises 0.1-5.0 wt. % a dispersing agent, 0.01-0.08 wt. % an antifoaming agent, 0.01-10 wt. % a disintegrating agent, 0.01-1.0 wt. % a stabilizer.  
   
   
       11 . The soluble granule of  claim 10 , wherein said phosphoroamidothioate compound is acephate.  
   
   
       12 . The soluble granule of  claim 10 , wherein said dispersing agent is a derivative of sulfonated fatty alcohol, said antifoaming agent is a silicon oil derivative, said disintegrating agent is selected from the group comprising bentonite and zeolite, and said stabilizer is a salt of a higher fatty acid.  
   
   
       13 . The soluble granule of  claim 1 , wherein said soluble granules are spherical granules.  
   
   
       14 . The soluble granule of  claim 1 , wherein said angle of repose is 16-18.  
   
   
       15 . A soluble granule comprising, 
 a) 75 to 98 wt. % a phosphoroamidothioate compound of the following formula:                          wherein R and R 1  individually are an alkyl, alkenyl or alkynyl group containing up to 6 carbon atoms, R 2  is hydrogen, an alkyl group containing 1 to 18 carbon atoms, a cycloalkyl group containing 3 to 8 carbon atoms, an alkenyl group containing 2 to 18 carbon atoms or an alkynyl group containing 3 to 18 carbon atoms, R 3  is hydrogen or an alkyl group containing 1 to 6 carbon atoms, and Y is oxygen or sulfur;    b) 0.1-3.0 wt. % a wetting agent; and    c) a filler to make 100 wt. %, said soluble granule has a bulk density less than 0.37.
