What are the precautions for pesticide dilution?
a. Using water as a dilution When spraying liquid to control diseases, insects and grasses, it is necessary to dilute the pesticide with water as a dilution. When diluting, first of all, pay attention to the water quality of the water. The quality of the water is measured by its PH value and hardness. The pH value is preferably neutral; the hardness of water above 10 degrees is called hard water, and the water below 10 degrees is soft water. Diluting the pesticide with hard water reduces the suspension of the wettable powder or destroys the emulsifying properties of the cream, thereby reducing the efficacy or causing phytotoxicity. So use soft water to dilute. Under normal circumstances, unpolluted river water, canal water, lake water or rainwater are soft water. Secondly, the water used to dilute the pesticide should be clean and free of floating debris.
b. Using soil as a diluent When soil is used as a diluent, the soil selected should be a moist fine soil free of saline and alkali. The texture of the soil should not be too heavy, and the fine loam is better. The humidity is squeezed into a group by hand. When standing, it is easy to loosen the soil.
c. When diluting, the dosage of the drug and the diluted substance must be accurately weighed and must not be estimated arbitrarily.
d. When diluting, the dilution and the drug must be thoroughly stirred and mixed well.
Precautions when using pesticides
(1) When dispensing, the dispensing personnel should wear rubber gloves, and the measuring device must be used to weigh the liquid or powder according to the prescribed dosage, and the dosage should not be increased arbitrarily. Do not mix drugs by hand.
(2) Seed dressing should be stirred with tools, how much, how much to mix, the seeds mixed with the medicine should be planted with the machine as much as possible. Wear protective gloves when hand or sprinkle to prevent skin absorption. The remaining poisons should be destroyed and not allowed to be used as food or feed.
(3) Dispensing and seed dressing should be kept away from drinking water sources, and the safe place of the residential area should be guarded by special personnel to prevent pesticides, poisonous species from being lost or eaten by people, animals and poultry.
(4) When spraying with a manual sprayer, it should be sprayed alternately. Manual and mobile medical devices can not be sprayed on both sides. Spray should be stopped during high winds and high temperatures at noon. The liquid medicine in the medicine barrel cannot be overfilled, so as not to shake out the barrel and contaminate the body of the application personnel.
(5) Before spraying, carefully check whether the screws on the switch, nozzle, etc. of the medicine machine are tightened, and whether the medicine barrel is leaking, so as to avoid leakage of drugs. If there is a blockage during the spraying process, it should be washed with clean water before troubleshooting. It is absolutely forbidden to blow the nozzle and filter with the mouth.
(6) Where high-toxic pesticides are applied, signs should be erected, and grazing and mowing should be prohibited for a certain period of time to prevent poisoning of humans and animals.
(7) After the end of the medication, the sprayer should be cleaned in time, returned to the warehouse with the remaining medicine, and must not be taken home. The sewage from cleaning the medical equipment should be properly disposed of in a safe place, and it is not allowed to spill anywhere to prevent pollution of drinking water sources and fish ponds. Packaged articles that contain pesticides are not allowed to contain food and feed such as grain, oil, and alcohol. Empty containers, bottles, bags, etc. filled with pesticides should be treated centrally. The used water tank for soaking should be washed and stored in a centralized manner.

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
