Pepper pest control method

The common names of white-earth silkworm and white-headed silkworm are polyphagous pests that bite off the roots and stems of the seedlings and cause dead dead seedlings; they feed on the roots and tubers and affect the yield and quality.

Control methods: (1) Chemical seed dressing: This is a simple and effective measure to control the economics of underground pests. Use 50% phoxim EC 10g water 50 ~ 100g, mix seeds 0.5 ~ 1 kg, or 40% methyl strataphor EC 10g, add water 160g, seed dressing 1.6 kg, can effectively control wolfberry and Other underground pests are harmful.

(2) Soil treatment: 50% phoxim EC or 40% methyl isothiphos EC, 200-500 g, and fine soil 25-30 kg (dilute the liquid 10 times with water and mix evenly In the soil, apply smoothly and smoothly. Immediately after the application, sprinkle with water or rain before applying it. The effect is better; or directly add water 1000 to 1500 kilograms, water, and then shallowly to Reduce photolysis failure, RI long residual period.

(3) Chemical control scarab: Spray insecticides such as dimethoate and omethoate on the poplar, eucalyptus and mulberry that like to feed on the beetle or scrape off rough skin on the 1.5m tall trunk 40% omethoate plus 1 The water solution can effectively kill the beetle and reduce the population density of the beetle.

(4) Blacklight trapping and killing of scarabs: Wherever conditions permit, a black light trap can be set up for every 50 mu of land to trap beetles, and it can also trap and kill other pests. For example, a black and green single-tube dual-lamp (half green light, half Black light) or black and green double tube light (the same lamp with black and green light tubes) works better.

(5) Agricultural Control Law: Deep plowing in winter, eliminating overwintering insects and reducing the source of insects in the coming year. In severe fields in the year round, the land was planted with ramie to repel and poison the beetle.

(6) Biological control: The natural enemies of crickets, such as walking armor, hidden wing armor, squirrel rat, and birds, shall be protected and utilized. Prevention of earthworms with Beauveria bassiana and emulsion-like microorganisms has been widely used in foreign countries. China is also introducing or separating tests, and will soon be promoted in production.

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.
