First, the product registration number. China has implemented a pesticide registration system. All pesticides produced, processed, distributed and sold in China are covered by pesticide registration management. Pesticides can be produced, sold and used after registration. Do not buy pesticides that do not have a registration number on the label when purchasing pesticides.
Second, the product is valid. China stipulates that general pesticides should have a two-year validity period, that is, the content of active ingredients and main indicators within two years after leaving the factory meet the quality standards. Do not purchase pesticides that are longer than the expiration date or that are not marked for expiration.
Third, do not buy damaged pesticides.
Fourth, do not buy pesticides with incomplete or unclear labels.
5. Judging the pros and cons of the appearance of pesticide products. Powders and wettable powders may be damp if they are agglomerated. Not only the fineness is not required, but the active ingredient content also changes. If there is more graininess, generally the fineness does not meet the requirements; if the color is uneven, there may be quality problems.
If the emulsifiable concentrate is turbid and crystallized, and the crystallization does not disappear after being exposed to the normal temperature for a period of time, it indicates that there is a certain quality problem. Unevenness of the emulsion after emulsification of the emulsifiable concentrate with water or oil slick, sediment, and eucalyptus indicate quality problems. If there is agglomeration after the suspension of the plastic suspension, there is a quality problem. If the tablet for fumigation is in powder form, it indicates that it has failed.
Sixth, quality inspection. If the quality of the pesticide is suspected, the most accurate and reliable method is to send the pesticide sample to the local pesticide testing center for inspection according to the quality standard.

solar street lights are raised light sources which are controlled by solar powered boards commonly mounted on the lighting structure or coordinated into the shaft itself. The sunlight based boards charge a battery-powered battery, which controls a fluorescent or LED light during the night. There are two types of solar light generally in the lighting market which called all in on solar street light and split solar street light.
Features of solar street lights: A modern solar street light has embedded solar panel, inbuilt lithium-ion batteries, battery management system, night and motion sensors as well as automatic controls. The fully automatic device comes with LEDs, inbuilt and replaceable Lithium-ion battery and passive infrared (PIR) sensors. A typical solar street light is weather-proof and water-resistant, has low insect attraction rate and low glare and has a longer life.
Advantages of solar street light:
Environmental protection: solar energy is green, clean and renewable energy. And the widely using of the solar lights can low down the emmision of the carbon dioside.
Cost less to save money: Since the solar lights can be 100% energy, zero electric bill will be paid after the customers install the solar lights. And customers can also save the cost in wire trench.
More easy installation: Does not like electric lights, there is no need wire trench for solar light installation. Everyone can install the solar lights in a very shorten time.
more safe: Solar lights is DC low voltage compared to dangerous 110-220V AC electric power, it does not harm to human.
