As the temperature gradually decreases and foggy weather becomes more frequent, sharp pepper disease has become increasingly common in greenhouses. Recently, many vegetable growers have reported various issues during the cultivation of hot peppers. The following problems that have been observed for some time are now summarized for reference by farmers:
One case involved a farmer from Wutai, Shouguang City, who called to report that his peppers were shriveling. He was concerned whether it was a viral infection. The symptoms described—dry shrinkage in the heart of the pepper—can be indicative of a viral disease. When infected with a virus, peppers may show mosaic leaves, fern-like leaves, bright veins, stunting, yellowing, necrosis, or top drying. Among these, the fern leaf virus is known to cause the heart of the pepper to shrink. Affected plants often exhibit overall stunting, increased branching, and plexiform growth. The mesophyll tissue in the center becomes degenerated, and the leaves become smaller or take on a fern-like appearance. In later stages, the plants may become distorted. If your peppers display similar symptoms, it's likely they've been infected by a virus.
To control this, the following treatments can be applied: 120% Virus A wettable powder diluted 500 times, 2 Virus Net or Virus Spirit at 500 times, 1.5% Phytopathogenic Ling Emulsion at 1000 times, and Anti-Toxic Agent No. 1 at 400 times. Spray every 10 days for three consecutive applications.
Another possible cause of leaf and heart shrinkage is aphid damage. Aphids can cause dark green, thickened, and brittle leaves, with a shiny underside. Severe infestations may lead to curled leaves. Under a magnifying glass, aphids can be clearly seen. To manage aphids, use agents such as Detritus, Avermectin, or Efford 1.
In addition to viral and insect-related issues, Mr. Liu Mingjie, a senior expert from the Vegetable Society of Shouguang City, pointed out that phytotoxicity caused by improper pesticide use can also lead to similar symptoms. There are two types of phytotoxicity: one caused by hormonal imbalances due to excessive hormone application, and another from over-concentration during spraying.
Hormonal intoxication typically affects young leaves near the growing point, causing twisted veins, thick and stiff leaves, darkening, and rolled edges. These symptoms often appear near the fruit. According to Mr. Liu, this is commonly caused by excessive hormone use. To avoid this, hormone-containing products should be avoided, and alternatives like Harvest No. 800 (hormone-free) can be used to control plant growth safely.
The second type of phytotoxicity occurs when pesticides like Metalaxyl-MnZn, Glucosyl, or Mancozeb are used in high concentrations. While farmers may want to use strong treatments after a severe outbreak, even mild infections can lead to phytotoxic effects on young leaves, causing them to shrink or curl. In such cases, applying Harvest No. 800 at 800 times dilution or using products like "More Love" can help reduce damage.
A case of round pepper spot virus was also reported in bell peppers. During a visit to Shengcheng Town in Shouguang City, a grower showed two affected peppers with brown stripes on the surface, but no changes in the flesh. Experts confirmed this as the round pepper spot virus, also known as "yellow shooter." This disease spreads through insect vectors or mechanical damage. Prevention is key, especially during peak seasons.
Prevention measures include removing and destroying infected plants, controlling pests with insecticides like Imidacloprid, Net, or Aketai, and setting up insect nets at vents. Foliar sprays of Harvest 800 mixed with 0.1% zinc sulfate can also help prevent viral infections. Additionally, antiviral agents like bactericidal agents, virus-clearing solutions, and anti-toxic products can be used to reduce the risk of infection.
Another issue reported by a farmer on Wenjiao Street in Shouguang City was that his sharp pepper seedlings were not growing well. Despite no visible problems in the seeds, the plants remained short after emergence. The problem was traced back to the nursery environment. Seedlings were grown in arch sheds, where temperatures were initially adequate, but dropped after emergence. Poor insulation further reduced the internal temperature, affecting seedling growth.
To improve this, the farmer is advised to enhance insulation by covering the shed with straw or small tents. Regular spraying of Harvest No. 800 at 800 times dilution can strengthen the seedlings' cold resistance and promote healthier growth.
Engineering Vehicle Parts
This classification mainly includes the aluminum die casting Machinery Parts using in Engineering Vehicle area.
From the part, we can easily find that the parts have a lot of features of big cavities, so the part will have big potential risk of mold release problem, if so, the part may happen to be deform, sticking to the mold etc, especially when the part sticking to the mold, if no clear in time, while next shot, the mold may be destroyed while clamping.
