Potato is a common vegetable in life. It is delicious and nutritious, and is very popular among you. In the process of potato planting, some diseases will inevitably occur. This article will introduce the pesticide solutions for potato diseases in detail for your reference.
1 potato late blight is the selection of disease-resistant varieties; the second is the use of disease-free seed potatoes; the third is drug control. In the early stage of the disease, spray 58% metalaxyl Mn-Zn wettable powder 600-800 times solution, or 64% anti-virus WP WP 500 times solution, or 72.2% Plex water 800 times solution, or 50% Famili 500 times solution , or 3% anti-mycin WP 300 times solution, or 75% chlorothalonil WP 500 times solution, or 1:1: 200 Bordeaux solution, spray every 7-10 days, continuous 2- 3 times. Spraying 1000 times plant power in the seedling stage and early flowering stage of the potato can significantly reduce the damage of the disease. In short, the prevention and control of potato late blight should be based on the promotion of disease-resistant varieties, the selection of disease-free seed potatoes, combined with prevention, elimination of central diseased plants, strengthening of chemical control and improved cultivation techniques for comprehensive prevention and treatment.
2 Potato early blight is the first crop with the non-solanth crop; the second is to apply the base fertilizer, increase the application of phosphorus and potassium fertilizer, and improve the disease resistance of the plant; At the beginning of the disease, Spray 1:1:150 Bordeaux mixture, 80% Dyson zinc 600-800 times solution, 75% chlorothalonil 600-800 times solution, spray according to the incidence of 5-7 days, a total of 3-4 times Take control.
3 Potato ring rot ring rot is mainly the transmission of seed potato, the seed potato is the primary source of infection, and the dicing is the main way of transmission. Experiments have shown that generally more than 20 healthy potatoes can be infected with more than 20 healthy potatoes, up to 60. After field investigation, the incidence rate of the disease can reach 68.97%. Prevention and control should adopt comprehensive measures combining the selection of disease-resistant varieties, the removal of diseased plants in the field and the selection of low-toxic pesticides . The diseased plants were excavated in the seedling and adult stages and concentrated. Diseases in the field can be sprayed with 72% agricultural streptomycin 4000 times solution, or 2% spring seromycin WP 500 times solution, or 77% can kill wettable micron powder 500 times solution, or 25% lycopene copper solution. 300 times solution, or 50% DT wettable powder 500 times solution.
4 potato black scorpion disease is the selection of disease-resistant varieties; the second is to establish disease-free seedlings; the third is to take the principle of prevention and control based on agricultural measures. The disease prevention and treatment method is the same as the ring rot.
5 Potato virus disease So far, there is no specific agent, which can only be prevented from agricultural technology. Use virus-free seed potatoes. In the early stage of the disease, spray 1.5% of the phytopathogenic emulsion 1000 times solution, or 20% of the virus A wettable powder 500 times solution, or 5% of the bacteriocin clear WP 500 times solution, or the dimethoate emulsion 2000 times solution, every 7- Spray once every 10 days and spray 2-3 times continuously.
The above is the solution to the potato disease introduced in this article. I hope that everyone can help plant potatoes. Finally, I wish everyone can grow away from pests and diseases and thrive.
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
