Use 40% strong Chloride 200 times soaking. Seed soaked with water for 12 hours, and then soaked in liquid for 12 hours, then rinse with water, remove germination, sowing, can prevent bacterial streak, bacterial blight and so on.
Soaking seeds with 0.2% copper sulfate solution for 48 hours, then removing germination and sowing, can prevent bastard disease, rice smut and so on.
Use 40% formalin 500x soak. Seed soaked with water for 1 to 2 days (to absorb enough water without dew-whiteness), remove it, dry it slightly, soak it in the liquid for 48 hours, remove and rinse with water, and then germinate and sow. It can prevent rice blast, bastard disease, leaf spot disease, smut, and rice smut.
Use 10% Ye Shujing 2000 times liquid soaking for 24 ~ 48 hours, remove the germination, sowing, can prevent bacterial blight, bacterial streak disease and so on.
The solution is soaked in 0.15% of the bacilli solution for 48 hours. After rinsing with water, the seeds are germinated and sown to prevent acanthopanemasis and bastard disease.
Soaking seed with 500% liquid soaked for 10 to 60 hours with 10% soaking seed can prevent bastard disease and prevent acanthopanemasis and rice blast disease.
Take appropriate amount of 70% hymexazol (soil bacteria elimination), before sowing by 0.4% ~ 0.7% of the dry rice seed mix, dry mix, wet mix can prevent seedling blight and so on.

Hyaluronic Acid Eye Drops Sodium Hyaluronate (HA), Pure Hyaluronic Acid could be used in eye surgery, such as Hyaluronic Acid Eye Drops, corneal transplantation, cataract surgery, glaucoma surgery, and surgery to repair retinal detachment.
Eye Drop Grade Hyaluronic Acid Powder is an important component of intercellular substance, eye vitreous body, joint fluid and other connective tissue. It acts the important physiologic roles in holding body's moisture, maintaining extracellular space, adjusting osmotic pressure, lubricating and promoting cells to repair in the body. Sodium Hyaluronate can be used as viscoelastic agent inintraocular lens implantation operation, as the filler in the osteoarthritis and rheumatoid arthritis and otherjoint surgery, as a medium widely used in eye drops, it also can be used to prevent postoperative adhesion and facilitate the wound heal. The compounds formed by the reaction of Sodium Hyaluronate with other drugs play a drug release effect role, thus achieve the purpose of drug targeted and time controlled release.
With the development of medical technology, Sodium Hyaluronate has been more and more widely used in medical applications. In 1976, Sodium Hyaluronate was first commercialized and used as ophthalmic viscoelastic agents, which is a significant progress in the ophthalmic industry. In 1987, Sodium Hyaluronate for intra-articular injection came in to the market. In 1990s, the large-scale production of Sodium Hyaluronate by fermentation made the cost lower, thus products containing Sodium Hyaluronate such as eye-drops, dermal fillers and other Sodium Hyaluronate preparations started to be used extensively.
