Sulfur is an important variety of inorganic pesticides. The commodity is yellow solid or powder, has obvious smell, can volatilize. Sulfur water suspension is slightly acidic, insoluble in water, and reacts with alkali to generate polysulfide. When sulfur burns, a cyan flame is emitted, and sulfur dioxide gas is produced along with the combustion. In production, sulfur is often processed into a colloidal suspension for the prevention and control of diseases and insect pests. It is safe for people and animals and is not easy to cause phytotoxicity to crops.

Main use

1, used for the prevention and control of pests and diseases, often processed into a suspension, it is safe for people, animals, not easy to make crops produce damage.

Sulfur is a multifunctional agent, in addition to a bactericidal effect, but also can kill mites and insecticides. It is used to control powdery mildew and leaf grubs of various crops, and the effective period can reach about half a month. Sulfur gum suspension used in vegetables is mainly used to prevent powdery mildew of melons, such as cucumber, melon (cantaloupe), pumpkin, etc. When used, 50% sulfur gum suspension is diluted into 200-400 times liquid spray. Spray once every 10 days or so, the general incidence of light medication 2 times, severe cases of medication 3 times.

2. Sulfur is a mineral, which is acidic, warm and toxic, and belongs to the kidney and large intestine.

The effect is that external use can kill insects and relieve itching. Can be used for mange, eczema, skin itching. Some people also use it to burn smoke to treat itching of male scrotum or female vulva. It can also be sprinkled with powder. It is now believed to produce hydrogen sulfide and pentasulphic acid in contact with the skin, which can kill mange, kill mold, and remove hair.

With the development of the transportation industry, radial tires will gradually replace oblique rubber tires. Thus, the insoluble sulfur has attracted more attention as a main vulcanizing agent for the production of radial tires.

3. Disinfection and sterilization

Sublimation of sulfur, also known as sulfur, contact with the skin and tissue, in the role of its secretions under the formation of sulfide, so that the skin softening and bactericidal effect. Sulfur settlement, also known as sulfur milk, contact with the skin can produce hydrogen sulfide and five sulfuric acid under the action of its secretions, sterilization, killing scabies.

4, laxative effect

The role of sulfur itself is not active, and it becomes sulfide and hydrogen sulfide after oral administration, which stimulates gastrointestinal mucosa, excites peristalsis and causes diarrhea. This process requires an alkaline environment, the presence of E. coli and, in particular, lipolytic enzymes. Intestinal content, fatty substances more, easy to produce a large number of hydrogen sulfide and diarrhea. High concentrations of hydrogen sulfide in the air can directly paralyze central nerve cells and cause death.
