Various forms of elemental sulfur, dry flowable, water-dispersible granules, soluble concentrates, wettable powder. Finely ground sulfur for dusting is made free-flowing by the addition of 1-5% clay, talc, gypsum, tricalcium phosphate, or similar material. May be made especially fine by micronizing. Sulfur grinding involves a high degree of explosive hazard. Colloidal sulfurs, smaller particles than those produced by ordinary grinding processes, may be produced in several ways, generally by acidifying lime-sulfur solution or similar reaction. Flowable sulfur is microfine sulfur formulation in aqueous suspension form. Strong adhesive properties act as a sticker and deposit builder for other spray materials. Micronized wettable sulfur is specially made into a carefully balanced extremely fine particle size. Wettable sulfur is prepared by adding wetting and dispersing agents to finely ground sulfur, since sulfur itself cannot be suspended in water.
