Right now, at the peak of agricultural production and pesticide use, it is very important for farmers' friends to simply and intuitively identify the inferiority of the pesticide .
Looking at packaging China has strict regulations on the packaging of pesticides and their labeling, and some non-standard pesticide manufacturers often have problems in the outer packaging.
1. The formal product packaging is exquisite and the text is clear. Non-standard product packaging or excessively fancy or rough printing, blurred text patterns.
2. China stipulates that there are two kinds of pesticide product names. One is the common name, which is marked by the actual active ingredients contained in the product, such as avermectin, imidacloprid, carbendazim, etc. When the product contains two or more ingredients at the same time. The common name can be abbreviated, for example, averaging chlorpyrifos, high chloride chlorinated salt, etc., the common name must be marked in a large font on the marked position of the label; the second is the product name or brand name, such as multi-target, Feige T, etc., but The font of the product name cannot be larger than the common name. Non-standard products often only contain exaggerated product names.
3. The “three certificates†are complete and true, that is, the pesticide registration certificate, production approval certificate and quality standard starting with LS or PD.
4. The object of prevention and treatment and the dosage used in the product label must be consistent with the actual contents of the registration certificate and must not be increased arbitrarily. Non-standard products are often not registered in the Ministry of Agriculture, and free to fill in the prevention and treatment targets, sometimes a drug can prevent more than a dozen pests and diseases and even cure all diseases!
5. The exact address and contact number of the label must be indicated in the label. Non-standard products are often only marked with false information such as “××Group Development†or “×× Company Honorary Productâ€. The contact number is either a fake number or a mobile phone. number.
6. Other content. Production date and shelf life, toxicity label, and precautions are all important items.
An important reason for the prevalence of counterfeit and counterfeit products is the price advantage of pesticides . If the price of the product is significantly lower than the market price or it is easy to cut from the initial high price to a very low price, in most cases the quality of the product is problematic.
Simple test By looking at, touching, smelling the appearance or smell of the drug, it is easy to identify the quality of the drug by taking a small amount of the agent into the water to check its diffusivity and stability.
1. Touch, smell, and watch. Hand touch WP packaging, if you feel that the agent in the package is like water, it means that the agent is finely ground and the quality is good; the emulsifiable preparation is placed in a position with good light, and the agent is evenly transparent, no delamination, no Precipitation indicates that the quality is good.
2. Simple test. Take a small amount of medicine and put it into a transparent container filled with clear water. Without stirring, the high-quality medicine will spread evenly. The liquid will not settle or stratify after being placed for several hours. The inferior agent will quickly sink or float. The stratification phenomenon; some of the emulsifiable concentrates become milky white after being mixed with water, and some become milky yellow. With the improvement of pesticide preparation technology, more and more emulsifiable concentrates, especially microemulsions, do not enter the water. Discoloration, the closer the color of the liquid to the transparent, the better the emulsified quality, which means that the quality of the agent is good. In the past, when the medicine was poured into the water, it changed color, and the color became thicker. The better the quality, the better the standard. Conversely, inferior pesticides are poured into the water either in a very dark or oily stratification.
According to the China Pesticide Network , with the development of pharmaceutical production technology, pesticides have begun to move away from the word “demonicâ€. Previously, a little medicine was placed on the worm to check the death speed of the worms to verify the insecticide. The method of quality of the agent has not met the quality verification standards for modern pesticides. “Efficient and low toxicity†and “effective control†are the real performance of high quality pesticides. Slow drug efficacy does not mean that the drug effect is not good. In order to profiteering, some unscrupulous manufacturers cater to some people's "high toxicity" and "fast" are efficient misconceptions. Adding high-toxic components such as phorate, carbofuran and methomyl to the pharmacy is a fake and shoddy thing. The most common behavior in pesticides.
Sodium Hyaluronate is very important for skin because it improves moisturization, maintains skin resilience, and reduces damage in the lower part of skin when the skin is damaged. It also acts like lubricant by causing collagen, a main constituent of skin, to move smoothly in between cells.
But from the age of 25, Sodium Hyaluronate in human body will lose gradually, only remaining 65% of young skin at the age of 30, only 25% of young skin at the age of 50.
With the increase of the age and the loss of Sodium Hyaluronate, the skin will lose elasticity and luster, aging, wrinkles and relaxation will be generated gradually.
Sodium Hyaluronate is so water-friendly and it has functions of the best moisturizing factor and prevents diseases such as skin infections by preventing the penetration of external substances such as bacteria.
Therefore, it is regarded as an ideal "natural moisturizer" factor and widely used in cosmetics that suitable for different skins, climates and environments.
High molecular Sodium Hyaluronate can be formed breathable film on the surface of the skin, help the skin to lock moisture, and to prevent the invasion of bacteria, dust and ultraviolet, so that to protect the skin from damage.
Low molecular Sodium Hyaluronate, which is designed for better skin penetration, can penetrate into the dermis quickly, dilated capillaries slightly, promote blood circulation and metabolism, and so it has function of eliminating wrinkles, increasing skin elasticity and preventing skin aging.
