Do not use expired pesticides

Medicines and pesticides have a certain shelf life. Once people eat expired drugs, they will not cure the disease, but they will have other adverse consequences. If the crops use pesticides that exceed the shelf life, it will not cure the disease. The effect of the worm, on the contrary, can also cause phytotoxicity to crops. Nowadays, it is the high incidence period of crop pests and diseases, and it is also the season in which pesticides are used most frequently. In order to prevent the occurrence of various accidents and avoid unnecessary economic losses, the author reminds the farmers: Do not use expired pesticides. At the same time, several suggestions are proposed for farmers' brothers to use as a reference when using pesticides. First, the purchase of pesticides must go to the formal agricultural capital units. When purchasing, first of all, we must clearly see the pesticides to be purchased. After that, we must see the production date and product specifications of the pesticides, because the pesticides have shelf life, if found over Do not buy pesticides with shelf life, close to the shelf life of pesticides, try to use as much as possible to buy, now buy now. Second, if there are surplus pesticides in the households in the previous year, before using this year, first of all, it is necessary to see whether the labels are in good condition. If they are still in the shelf life, if they find that the pesticides have exceeded the shelf life, they are advised not to be better. If the remaining pesticides are peeled off and the pesticides cannot be confirmed, do not use them indiscriminately to avoid causing phytotoxicity to crops and cause greater losses to the economy. 3. Anyone who purchases unused pesticides this year and prepares to use them until next year, the water agent must be tightened with the bottle cap. The powder should be tightly packed to prevent the volatilization from failing. However, it is worth mentioning that you should not mix and store the remaining pesticides. The stored pesticide must have a complete bottle sticker. The name of the pesticide, the batch number, the date of manufacture and the shelf life should be clear. The stored pesticide must be placed in a cool and ventilated place.

Titanium Alloy

Titanium alloy is a class of metallic materials widely used in various high-performance applications. It is a combination of titanium with other elements, such as aluminum, nickel, molybdenum, and vanadium, to enhance the properties of pure titanium.

One of the key advantages of titanium alloys is their high strength-to-weight ratio. They are significantly lighter than steel while being just as strong, making them ideal for aircraft, missiles, and spacecraft. Moreover, titanium alloys possess excellent corrosion resistance, which makes them highly suitable for marine, offshore, and chemical processing environments.

In addition, titanium alloys exhibit good biocompatibility, which makes them suitable for medical implants such as artificial joints, dental implants, and pacemaker cases. They also have high fatigue resistance, low thermal expansion coefficient, and excellent weldability.

Overall, titanium alloys have become an essential material in many industries, including aerospace, marine and offshore engineering, chemical processing, biomedical engineering, and sports equipment. As research continues to advance, it is expected that more innovations in the field of titanium alloys will arise, paving the way for even safer and more efficient applications.
