Sharp pepper heart dried up shrinkage Shouguang City Wutai a vegetable farmer called to inquire, the cultivation of the pepper shrivelled, and asked if it was a virus disease?
The phenomenon of dry shrinkage occurs in the heart of the pepper, and it may be the occurrence of a viral disease. After the pepper is infected with the virus, there may be various symptoms, such as mosaic leaf, fern leaf, bright vein, dwarfing, yellowing, necrosis, and top dryness. Among them, the fern leaf virus disease that causes the shrinkage of the heart of the pepper is caused by the fern leaf virus. After the occurrence of this virus disease, the diseased plants showed varying degrees of whole-plant shrinkage and dwarfing symptoms and increased branching, showing plexiform branches. The mesophyll tissues of the heart were degenerated, the leaves became smaller or there were fern leaves, and the diseased plants were distorted at the later stage. If the symptoms of the pepper are similar to those described above, it is likely that the virus disease has occurred. It can be controlled by the following methods: 120% virus A wettable powder 500 times; 2 virus net or virus spirit 500 times; 31.5% Phytopathogenic Ling-emulsion 1000 times; 4 anti-toxic agent No. 1 400 times, spraying once every 10 days, continuous spray 3 times.
The damage of new leaves caused by drug injury: The damage of aphids may also cause the heart and leaves to shrink. The specific symptoms are dark green leaves, thickening and brittleness. The back of the leaves has a shiny luster. When the aphids are seriously damaged, they cause leaf curling. The locust activity can be clearly seen under high magnification magnifying glass or microscope. For locust infestation, it can be sprayed with agents such as detritus, avermectin, and efford 1 for control.
In addition to the above two reasons, Liu Mingjie, the chief expert of the Vegetable Society of Shouguang City, also put forward the following point: The injury of medicine may also cause the heart and leaves of peppers to shrink.
There are two kinds of phytotoxicity, one is hormonal intoxication caused by improper use of hormones, and the other is direct phytotoxicity caused by excessive concentration during spraying. The occurrence of hormonal intoxication occurs mainly on the young leaves near the growing point, the leaf veins are twisted and twisted, the leaves are thick and stiff, the color darkens, and the leaf margins are rolled up. The curled leaves, hardened, dark green, etc. appear near the fruit.
According to Mr. Liu, the above phenomenon is mostly caused by excessive spraying of hormones. The shrinkage and curling of the leaves near the growth point are due to poisoning caused by excessive hormone accumulation at the top of the plant. In order to avoid hormone-induced heart and leaf shrinkage, the use of hormones should be strictly controlled. Try not to use hormone-containing preparations. If the pepper grows up, it can be sprayed with a harvest number 800 to control it. The drug is hormone-free and can be used with confidence.
Another kind of phytotoxicity is the phytotoxicity directly produced during spraying. Usually friends of vegetable farmers use metalaxyl MnZn, Glucosyl, Manson Manganese Zinc and other agents to prevent and control diseases or prevent diseases. The use of Mn-Zn medicines is likely to cause phytotoxicity. Now farmer friends are afraid that the disease can not be treated after severe disease. Once a disease occurs mildly, it can be prevented and treated with the strongest medicine. The old leaves may be able to withstand the lower part. The young leaves on the upper part are very likely to cause phytotoxicity, causing the heart and leaves to shrink. After the emergence of phytotoxicity, it can be sprayed with 800 times the harvest number or it can be relied upon for more love, avoiding the impact of plant damage caused by phytotoxicity.
There was a sporadic occurrence of the virus in the bell pepper. When the author visited the street in the city of Shengcheng, Shouguang, what disease did the vegetable grower hold with two bell peppers? The diseased bell pepper was covered with brown strips and there was no change in the flesh. It is known that the leaves of the pepper plants that have striae also do not have any adverse symptoms. They only have brown strips or yellow-brown spots on the fruit. They are diagnosed by vegetables experts of vegetable associations. This is the round pepper spot virus disease. Commonly referred to as the yellow shooter, this is the period when such diseases occur. Attention should be paid to the prevention and treatment of viral diseases and efforts should be made to minimize losses. Viral disease spreads mainly through infected wounds caused by insects or friction.
Prevention measures It is known that only two or three of the diseases occurred in the greenhouse. Experts of the vegetable association recommended that the susceptible plants be removed and packaged and transported out of the shed for destruction. And take the following prevention measures:
1, do a good job of pest control. Can be used imidacloprid, a net, Aketai and other agents for foliar spray, spraying once every 7-10 days to prevent the spread of viral diseases. At the same time, a network of insects should be set up at the vents to reduce insect damage.
2, spraying nutrition night. Can be foliar spray harvest 800 times mixed with 0.1% of zinc sulfate (1 two to three sprayer) for spraying, spraying once every 7 days or so, can effectively prevent the virus infection.
3. Spray antiviral agents. It may be used to prevent virus diseases or reduce the incidence of viral diseases by spraying agents such as bactericidal agents, virus clearing agents, phytosanitary psychics, bactericides, gram poisons, and anti-toxicity.
3, sharp pepper seedlings are not long. According to a vegetable farmer on the Wenjiao Street in Shouguang City, the planting of the pepper is not long, and I do not know what to do. There is no problem with the sharp pepper seed planted by the vegetable farmer, and the plant is not long after emergence. The problem lies in the nursery environment.
The cultivation of the vegetable seedlings is carried out in the arch shed, and the external temperature can also be used in the early stage of the next stage to ensure seedling temperature. However, after emergence, the temperature gradually decreases. With the decrease of the outside temperature, the temperature inside the arch shed is also declining. In addition, the heat insulation work of the vegetable cultivator is not done well, which causes the temperature inside the seedbed to be too low, which affects the growth of seedlings.
It is recommended that the vegetable farmer strengthen the insulation work, cover the grasshopper or cover the indoor small shed to ensure the proper temperature for the normal growth of seedlings. Pay attention to the regular spraying of 800 times the number one, enhance the cold resistance of seedlings, to achieve the purpose of cultivating strong seedlings.
Pepper Disease Analysis and Prevention
At present, the temperature is gradually reduced, with occasional foggy weather, resulting in frequent occurrence of sharp pepper disease in greenhouses. Recently, vegetable growers often report problems encountered in planting hot peppers. The problems that have occurred in hot peppers for some time are now collated as follows for reference by farmers:
