Common underground pest control methods

Underground pests are the natural enemies of crops, seed, seedlings and rhizomes that cause damage to seedlings and even destroy seeds, resulting in reduced crop production. Common ground pests are earthworms (scarab), golden needles (cockroaches), cockroaches (larvae), and ground tigers (cutworms). These pests have different symptoms of crop damage and should be diagnosed, identified, and controlled.

First, the diagnosis of symptoms

1. Aphid: Scarab larvae, feeding on the roots and stalks of the crops, often bite or bite off the roots of the crops. The hazard is characterized by relatively neat fractures, withered seedlings and death. Soybeans, sugar beets, and sorghum victims are heavier.

2. Goldworm: It is the larva of the esculenta. It harms wheat, corn, sorghum, potatoes, etc., and eats seeds, germs, and rhizomes. The hazard is that the young roots are eaten into small holes, resulting in dead seedlings, lack of seedlings, or tuber rot. .

3. Sputum: In the underground bite the seeds or germinating seed just sowed, and eat tender stems, roots, the hazard is characterized by biting into a mess, while the activities in the surface layer, forming a tunnel, the seedling root and soil separation The seedlings withered and died, and the millet suffered heavy damage.

4. Ground tigers: The larvae are very miscellaneous, endangering soybeans, corn, vegetables, and other crops. During the daytime, they are buried in soil and unearthed at night. The hazard is that the base of the stem is cut off, often resulting in severe crop failure and even destruction of the crops. Species.

Second, prevention and control technology. In areas with severe occurrence of cockroaches and pinworms, fertilizers should be mixed and stuffy species should be used. In areas with severe cockroaches, bait-dominated areas should be used. In areas where severe ground-worms occur, eggs should be deeply turned over, and weeding and insecticides must be used in combination with chemical control. .

1. Technology for the prevention and control of cockroaches and needles (1) Mix fertilizers, soak them with 5% formazan granules, and mix 1.5-1.8 kg per acre evenly. (2) Seed-dressing, seed dressing with soya seed coater ratio 1:75 or 35% methylthiophosphorus seed dressing at 0.5% of the seed amount, and boring. (3) Irrigating the roots and finding that the larvae are harmful, use 90% trichlorfon 1000 times or 75% phoxim 1000-1500 times to root, 100 grams per hole.

2. Antimony control technology (1) Poison bait, 1 kg of 40% Dimethoate or 90% Trichlorfon, appropriate amount of water, and 100 kg of sauteed wheat bran or bean cake, etc., a little bit stuffy, Saskatchewan tunnel opening , 1-1.5 kg per mu. (2) Insect extermination, use the phototaxis of earthworms, and use light to slay and kill; on the ground, dig 30-40 centimeters of square pits, pour a bit of fresh horse dung into the pits, and mix 2.5% of trichlorfon powder by 1/10 of the amount of horse dung. Trap.

(3) Control techniques for tigers (1) After the fall, the eggs are immersed and the eggs are sterilized before emergence. (2) poison bait trapping, with 80% trichlorfon WP 0.5 kg and 5 kg of sauteed bean cake, dubbed the appropriate amount of water on the bait, spreading in the evening in the affected fields, mu 1-1.5 kg. (3) Spraying, use 1000 times of 50% phoxim EC, use when the tiger is in the dusk.

Hyaluronic Acid For Skin, Sodium Hyaluronate is well known as the best [Natural Moisturizing Factor". For  Hyaluronic Acid Cream . In the early 1980s, the excellent moisturizing function of Sodium Hyaluronate has been widely concerned by international cosmetics industry. With its unique film-forming and hydrating characteristics, Hyaluronic Acid Powder Cosmetic Grade is used as a highly effective humectants in cosmetics. It attracts moisture to the skin and hold moisture in the skin, which preserve skin smoothness, suppleness and elasticity. 1 gram of Hyaluronic Acid Powder Cosmetic Grade is able to retain up to 1000 gram of water. So it is regarded as the [key to the fountain of youth".

The effects are as follows:

(1) Moisturizing effect 
Moisturizing is the most important effect of Sodium Hyaluronate in cosmetics products. It can be hydrated shell in skin surface and make the corneum hydration and softening. Compared with other humectants, Sodium Hyaluronate is less effected by the environment as it has the highest hygroscopic capacity in a relatively low humidity (e.g., in a dry winter), but has the lowest hygroscopic capacity in a relatively high humidity (e.g., in a damp summer). This unique property of Sodium Hyaluronate makes the skin adapt to different seasons.
(2) Skin nutrition effect
Sodium Hyaluronate is the inherent biological materials of skin. The exogenous Sodium Hyaluronate can complement the endogenous Sodium Hyaluronate. Low molecular Sodium Hyaluronate can penetrate into dermis directly to improve the nutrient supply.
(3) Skin repair effect
There is some evidence that topically applied Sodium Hyaluronate can reduce skin irritation from various causes. During clinical trials it was also shown that this ingredient is effective in promoting healing and fighting inflammatory conditions of the skin. Sodium Hyaluronate serves as a free radical scavenger and antioxidant, helping to protect the skin from the aging effects of excessive sunlight exposure.
(4) Emollient and Film-forming
Sodium Hyaluronate is high polymer with high lubrication and film-forming. Sodium Hyaluronate contained in cosmetics creates protective film on the surface of skin, which retains moisture, and at the same time prevents moisture in the skin from evaporation, so that improves freshness of the skin.  
(5) Thickening
Sodium Hyaluronate solution have high viscosity, and 1% solution is gelatinous. It can be added to cosmetics to improve the thickening and stability.
