First, pest species 1. Bacterial mosquitoes include eye-mosquito, small-mold, large-mold, and rhino mosquitoes. Adults are dark brown or yellow-brown and vary in length from 1.8 to 6 mm. The larvae are milky or gray-white, 4.7 to 16 mm in length and black on the head. The larvae are mainly used to injure the fruit bodies of edible fungi, and also harm the culture materials and mycelia, causing fruiting bodies to die or rot. 2. The fly flies include Drosophila melanogaster, drosophila, and flies. Adults brown or black, tentacles shorter than bacteria, larvae white, headless. The headless larvae are the main differences from the mosquitoes. Adults often eat and spawn on rotting fruit bodies. The larvae feed fruiting bodies and cause fruiting bodies to rot. They can also injure the mycelium and cause the mycelium to rot. 3, common hoppers have horned hoppers, blackhorn hoppers, black flat hoppers, etc. The body length is only 1 to 2 mm and it is good for jumping. The main bite fruit body also harms mycelium. Frequently inhabited. Make the fruit body full of pits. The weight can be eaten as young mushrooms and mushroom buds. 4. The length of the caterpillar is only 0.9 mm, and the caterpillar mainly harms the mycelia, causing the mycelia to die and die. 5. Anthraquinones have whiteflies, tyrophthalmos, grasshoppers, root pods, etc. They are small in size, about 0.2-0.6 mm long, and are not easily visible to the naked eye. Colorless milky white, yellow and white, reddish brown. It can harm mycelium and fruit bodies, and it can cause serious damage when it is seriously damaged. Second, the prevention and control methods 1. Clean mushroom house room before use to thoroughly clean, but also use 800 times the trichlorfon or dichlorvos disinfestation. For outdoor cultivation, remove the weeds around the cultivation site and spray the soil with 200-300 times the liquid of trichlorfon. Medicinal killing is also performed around the cultivation field to prevent insects from invading. 2. To prevent adults from entering the mushroom house door, windows, and vents, etc., use 60-mesh spun yarn to cut off and prevent entry of fungus mosquitoes and mushroom flies. 3. The trapping and killing adults can utilize the phototaxis of adult mosquitoes and mushroom fly and use black light or fluorescent light to seduce. Hang a dichlorvos tampon or place dichlorvos pots around the lights. You can also use honey, molasses, etc. to add a small amount of dichlorvos for trapping. 4. Chemical control 1 mushroom room fumigation --- under confined conditions, with 2 to 3 pieces of aluminum phosphide for fumigation per cubic meter of space to kill the insect source. 2 culture material processing --- can use the former method of fumigation of culture materials to eliminate the worms in the culture material. It is also possible to use dicofol to eliminate fleas. The amount of each 50 kg of culture material is 15 ml, 10 kg of water is added, and it is evenly sprayed on the material and accumulated for 3 days. The total treatment time is 2 times. It is also possible to mix 40% phoxim 500 times solution or enemy killed 1000 times solution, 50% omethoate 1000 times solution in the culture medium, and have good insect control effect. 3 bed surface control --- Insect pests found before the mushroom, can be sprayed on the bed 500 times solution of trichlorfon or 500 to 800 times dichlorvos, the enemy killed 1000 times and so on to kill, pest emergence during fruiting period At the time, all mushrooms must be harvested and then sprayed with the above-mentioned pesticides for killing.
Sodium Hyaluronate(HA), Hyaluronic acid could be used in eye
surgery, such as corneal transplantation, cataract surgery, glaucoma surgery,
and surgery to repair retinal detachment.
Eye drop grade Sodium Hyaluronate 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.
