Pests do not feed in winter and are the weakest link in their life cycle. Therefore, pest control in winter can often receive a multiplier effect. The main measures are as follows:
Cleaning Up the Pastures Some pests often lurk in the remains of host plants, such as roots, stubbles, dead branches, fallen leaves, and fruit droppings. After the crops are harvested, these residues are collected and burned, flooded, or buried in depth to eliminate a large number of overwintering pests.
Winter plowing Winter plowing Through deep plowing, the original living environment of the pests can be changed, and the deep soil pests can be turned to the surface to dry, freeze or be eaten by natural enemies, so that the insects in the deep underground can not be normally feathered and become suffocated. In order to reduce the overwintering source of insects, the winter irrigation followed by cultivation can not only sink and weather the soil, but also freeze some of the overwintering pests.
Eradication of weeds Some pests often migrate to the field and surrounding weeds for winter after crops are harvested. By early spring, these weeds are often the “refuges†and wild hosts of wintering pests. Therefore, the combination of manure and manure, eradication of weeds inside and outside the field, is an effective measure to prevent overwintering pests.
Some pests (corn maggots, etc.) that deal with the host are often hidden in the stem or cob of the host crop after the crop is harvested. Treating the stalks or cobs of these host crops in winter can greatly reduce the overwintering base of pests.

Function
Healthy Skin:
Hyaluronan is also a component of skin tissues, and helps in the repair of skin cell. It helps in tissue lubrication and faster healing of wounds. Another major benefit of this acid is its anti-wrinkle effects, as it helps the skin build up levels of collagen, increasing suppleness and moisture.
Treating Osteoarthritis:
Hyaluronic acid covers the spaces between the joints of the knees and protect the bones from damage due to friction. Injections of hyaluronic acid are prescribed to increase the level of this acid in the joints, and relieve pain. Even the oral intake of this acid through foods or supplements is helpful.
Healthy Eyes:
Hyaluronic acid is also beneficial to the eyes, as it can be used as artificial tears for dry eyes. The acid is used in many anti-aging creams for the face, and can also be injected into the wrinkles near the eyes, commonly known as 'crow's feet'.
Aesthetic Injections (Facial & Body)
Hyaluronic acid based gel injections(HA Dermal Filler) are a new option for the on-spot treatment of facial wrinkles. These shots must be administered by a dermatologist and last up to 4 to 6 weeks.
