The difference between pesticide phytotoxicity and crop diseases

The phytotoxicity and disease are easily confused, and in the production, the remedial measures are often delayed due to misjudgment, thus affecting crop yield. Therefore, it is very important to correctly understand and distinguish between phytotoxicity and disease, and it is helpful to take effective measures in time to reduce losses.

The occurrence of phytotoxicity caused by improper use of pesticides occurs frequently. The affected plants often have symptoms such as spots, yellowing, deformity, withering, growth stagnation, infertility, shedding, and inferior fruit.

As the temperature rises, everything recovers, and the pests follow the “wake up”, causing many crops to be damaged. The crop diseases and the phytotoxicity are very similar. Therefore, many farmers’ friends are difficult to distinguish clearly. Crop phytotoxicity and disease, indiscriminate application, the consequences are very serious.

The difference between spotted phytotoxicity and physiological disease is that the distribution of the former on the plant is often irregular, and the whole field is also light and heavy. The latter is usually common, and the symptoms of the plant are more consistent. Spot-type phytotoxicity and fungal diseases are also different. The former has a large change in spot size and shape; while the latter has a disease center and the spot shape is relatively uniform.

Compared with the yellowing caused by lack of nutrients, the yellowing caused by phytotoxicity often develops from yellow leaves into dead leaves. The sunny weather is more and the yellowing is faster. The lack of nutrients leads to yellowing and rainy days. Yellowing is slow, and yellowing is often related to soil fertility and fertilization levels. Compared with the yellowing caused by the virus, the yellow leaves of the latter often have a greenish appearance, and the diseased plants exhibit systemic conditions, and the diseased plants are mixed with healthy plants.

The difference between the malformation caused by phytotoxicity and the malformation of the viral disease is that the former is common and shows local symptoms on the plant; the latter often has sporadic incidence, showing systemic symptoms, often mixed with broken green, clear veins, wrinkles, etc. symptom.

Compared with the withering symptoms caused by invasive diseases, the former has no disease center, and most of them have slow process, first yellowing, post-dead strain, no browning of rhizome transporting tissue; the latter is mostly root-stem transduction. The tissue is blocked, and when the sunlight is sufficient and the amount of evaporation is large, the plant is wilted first, and then the green plant is lost. The root catheter often has browning.

The slowness caused by phytotoxicity is compared with the stiffness and deficiency of physiological diseases. The former is often accompanied by symptoms of plaques or other phytotoxicity, while the latter is characterized by poor growth of roots and the stiffness of dysfunction. The leaves are yellow or dark green.

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 ?

Good resistance to acids, such as sulfuric, phosphoric, nitric, and hydrochloric
Almost completely free from chloride induced stress corrosion cracking
Excellent mechanical properties at both extremely low and extremely high temperatures
Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion
High resistance to oxidation at elevated temperatures

In what Applications are Inconel alloys used ?

Chemical and petrochemical processing
Components where exposure to high mechanical stress and sea water are required
Flare stacks on offshore oil platforms
Gas turbines, rocket motors/engines, and space craft
Pollution control equipment
Nuclear reactors
