One of the important means of reducing pesticide residues and improving the safety of pesticide applications is to reduce the amount of pesticides used. During the application process, people generally try to make the agent cover the entire pest habitat. Due to the drift of the droplets and other environmental factors, the amount of pesticide reaching the biological target is extremely low. In the long-term study of the relationship between insects and plants, Professor Xu Hanhong proposed the concept of guiding pesticides, that is, the effective active ingredients (active warheads) of pesticides can be linked to the guide carriers and can cause damage to the pests or parts of the plants. Directionally cumulative pesticide formulations. In other words, where the pests are harmed, where the pesticides accumulate.
Most pests have specific damages on crops, such as cabbage caterpillars, Pinus elliottii, Plutella xylostella, etc., which have a habit of feeding tenderly; many pests are harmed from larval to adult stage, even in one part, such as Liriomyza sativae, citrus leaf miner, rice leaf roller, and coconut leaf beetle are only harmful on the leaves. Guided pesticides can accumulate in the harmful parts of these pests, thereby more effectively controlling pests and reducing the amount of drugs; reducing the toxicity of highly toxic pesticides, improving the safety of pesticides, reducing the toxicity of preparations to humans and animals, and reducing environmental pollution. .
The guiding pesticides are plant-based organisms (such as cucurbitacin on the leaves of the gourd) accumulated in the pest-damaged parts, which has opened up a new way for the research and application of plant secondary biomass. Guided pesticides make many secondary plant secondary compounds promising as commercial pesticides. Many plant active parts are flowers, fruits, seeds or bark, etc., the harvest amount is small, and the active ingredients are relatively complicated, and it is difficult to chemically synthesize. After the pesticide is made, the content of the active ingredients in the preparation can be reduced by several times or several times and the effect is unchanged. Then the demand for plant raw materials can be reduced accordingly. According to the Chinese pesticide network , this will result in many collections. It is impossible to achieve large-scale production requirements, and plant pesticides with high insecticidal activity may be converted into commercial pesticide products, completely changing the difficulty of large-scale production of plant pesticides.
INCONEL®
Yuhong Group supplies Inconel® alloys C-276, HX, 22, 600, 601, 625 & 718 in the form of Plate, Sheet, Bar, Wire, Pipe, Tubing, Pipe Fittings, Flanges and Electrode.
The registered trademark name, Inconel, is applied as the prefix name to more than twenty different highly corrosion resistant high temperature strength metal alloys produced by Special Metals Corporation. These Inconel alloys or superalloys are nickel-based alloys that exhibit traits such as high resistance to corrosion, oxidation, carburization, pitting, crevice, corrosion cracking, and high temperature strength. Often, Inconel is referred to as [Inco".
Alloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternativesto the various Inconel® brand alloys.
The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product. Chemical processing, nuclear, petrochemical, aerospace and marine industries widely use these superalloys.
What are the Characteristics of Inconel ?
