What is sputum Quercetin, also known as "Tao San San" and "Blazes", is an antibiotic extracted from actinomycete culture medium for the control of rice blast, rice husk, rice sclerotinia. The following small series will lead everyone to understand the use and use of quercetin.
Haohua Industrysupplies LDX2101, 2205, Ferralium 255, Zeron 100 and LDX2507 in the form of plate, sheet, strip, bar, pipe, tubing, pipe fittings, flanges and weld wire.
Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.

The role of quercetin is an antibiotic. It can inhibit the growth of yeasts and molds. What is used in agriculture is the sulphate and lauric acid sulphate. It is non-toxic to fish and is mainly used to control rice blast and diseases caused by Echinococcus. Control leafhoppers, panicles, and spray with 2% emulsifiable concentrate 500-1000 times (20-40 mg/L). The scutellarin has a certain effect on the control of rice leaf spot and small sclerotium disease, and also has a reducing effect on the infection rate of rice stripe virus disease. When the concentration exceeds 40 mg/L, it is prone to phytotoxicity. Before the spraying, the application of parathion, phoxim, trichlorfon, chlorpyrifos, fenthion or several arsenic agents should be mixed, but it should not be mixed with strong alkaline pesticides such as Bordeaux mixture. It can also be used in combination with amalgam pesticides.
The method of use of quercetin is mainly used for the control of rice blast, including seedling rice blast, leaf blast, panicle thorn, etc. It also has certain control effect on rice leaf spot and small sclerotium disease, and can also reduce infection of rice striated disease. rate. It is sprayed with 250% to 500 times of 1% wettable powder, which is harmless to crops. Before the onset of the seedlings, the spot is sprayed with 2% emulsifiable concentrate 500-1000 times, and the stems and leaves are sprayed 1 or 2 times, each time interval of about 7 days.
When I mentioned "Tao San San", I want to believe that everyone is familiar with it, but farmers must take precautions against the use of pesticides to prevent poisoning.
