Agricultural sulphur powder
Sulphur is a multifunctional insecticide, which can kill mites and kill insects besides bactericidal action. Powdery mildew and leaf grubs can be used to prevent and control various crops. Sulphur is also used to regulate soil acidity and alkalinity. Blueberries are suitable for growing in acid soils. The pH values of soil are between 4.5 and 5.5. With the popularity of blueberries increasing, more people are more interested in rapidly improving soil pH value. The lowest cost of reducing soil pH is to add elemental sulfur to the soil, turn sulfur into sulphuric acid through soil bacteria, and reduce soil pH.
