What does "S" or "SP" signify in pesticide terminology?

In pesticide terminology, "S" or "SP" signifies "Soluble Powder." This designation indicates that the pesticide formulation is in a powdered form that dissolves in water. This characteristic is essential for applications where a solution is needed for effective pesticide delivery. Soluble powders are often favored due to their easy mixing capabilities and the ability to create uniform solutions, which is critical for achieving the desired concentration and efficacy during application.

Understanding the nature of different pesticide formulations, including soluble powders, helps applicators choose the right product for specific pest management needs. Soluble powders are commonly used in agriculture and horticulture because they can be easily transported and measured for exact dosages.
