(1) Root rot is a serious issue that occurs in early May, especially before and after flowering, particularly under rainy conditions. The disease initially affects the lateral roots, causing them to turn black and eventually spread to the main root. Once the main root is infected, the entire root system begins to rot, leading to the death of the plant.
To prevent and control this disease, it is crucial to remove and burn any infected plants immediately to stop the spread to healthy ones. Applying quicklime or carbofuran around the affected area can help eliminate nematodes. Additionally, watering the soil with a 50% thiophanate solution diluted at a ratio of 1:1000 can be effective in treating the infection. Proper drainage and avoiding overwatering are also essential preventive measures.
(2) Diamondback moths pose a significant threat to the inflorescences of the plant. Once the larvae enter the flower clusters, they cause the flowers to wither and die, which severely impacts the yield.
For control, applying methamidophos as a foliar spray during the budding stage can help kill the larvae. In cases of heavy infestation, spraying dimethoate at a concentration of 1:1000 during the active period of the pests can effectively reduce their population. Regular monitoring and timely intervention are key to managing this pest successfully. It's also recommended to rotate insecticides to prevent resistance development.
A fence railing is a structure used to protect and define private or public spaces. It is usually made of different metal materials and is installed around the perimeter of a building, site or area to prevent unauthorized entry or to provide additional security. Fence railings are designed with aesthetics, functionality, and cost in mind.
1. Security & Privacy: Fences prevent outsiders from entering, protecting the safety of occupants or users, while providing a certain amount of privacy to the interior space.
2. Aesthetic decoration: With different designs, materials, and color options, fence railings can become a part of the landscape and enhance the overall aesthetic appeal.
3. Boundary Definition: Clearly define the boundaries of a specific area to help people understand what is accessible and what is restricted.
4. Wind and rain protection: In some areas, fence guardrails can also play a role in wind, rain protection, and protect the building from bad weather.
Material Type:
- Metals: such as wrought iron, aluminum alloy, etc., with strong durability and relatively low maintenance costs.
Design & Installation:
- Height: Depending on the purpose of use and regulatory requirements, the height of the fence guardrail may vary.
- Spacing: The spacing between the vertical rods is less than 110mm.
- Material strength: Ensure that the material chosen can withstand the expected environmental conditions and potential impact forces.
- Installation: Consider the ground foundation, soil conditions and terrain characteristics to ensure firm and stable.
