Preparations of sulfur suspensions

Abstract

Abstract AQUEOUS SUSPENSION OF FINELY SUBDIVIDED SULFUR HAVING PARTICLE SIZE RANGES SUITABLE FOR USE AS SOIL SULFUR AND/ OR AS PESTICIDAL SULFUR ARE DESCRIBED. THE INVENTION COMPRISES A METHOD FOR THE PREPARATION OF THESE SUSPENSIONS OF SULFUR WHEREIN POROUS PARTICULATE OF THESE SUSPENDED IN AN AQUEOUS MEDIUM AND IS SUBJECTED TO HIGH SHEER AND TURBULENCE BY PUMPING THE RESULTING SUSPENSION THROUGH A CLOSED CIRCULATION SYSTEM FOR A PWRIOD OF TIME FROM 5 TO ABOUT 200 MINUTES, SUFFICIENT TO COMMUNICATE THE PARTICULATE SULFUR TO A FINELY SUBDIVIDED STATE AND FROM A STABLE SUSPENSION OF THE FINELY SUBDIVIDED SULFUR. IN ITS PREFERED EMBODIMENT, THE SULFUR IS DISTRUBUTED AND HANBLED AS POROUS PARTICULATE SULFUR AND, AT THE APPLICATION SIITE, THE PARTICULATE SULFUR IS ADDED TO AN AQUEOUS MEDIUM CONTAINED IN THE VESSEL OF A CONVENTIONAL SPRAY APPLICATOR AND IS CIRCULATED THROUGH THE PUMP OF THE APPLICATOR AND RETURNED TO THE VESSEL FPR THE REQUISTE PERIOD OF TIME TO COMMINUTE THE SULFUR TO THE FINELY SUBDIVIDED STATE. WHEN THE SULFUR IS SUFFICIENTLY SUBDIVIDED, THE PUMP DISCHARGE IS DIVERATED TO THE SPRAY NOZZLES OF THE APPLICATOR AND THE SULFUR IS APPLIED TO THE SOIL OR THE PLANTS IN AN OTHERWISE CONVENTIONAL PROCEDURE.
