How to prevent and control Zanthoxylum root rot? What is the prevention and control of root rot of p

The main causes of Zanthoxylum bungeanum root rot are as follows: excessive fertilization, too frequent (root burning), farmhouse manure is not fully cooked, excessive water accumulation, high temperature, bacterial infection, pests and diseases, and continuous anaerobic respiration of Zanthoxylum bungeanum roots. <>

The economic value of the pepper tree is relatively high, and many people like to plant, but there are many things that need to be paid attention to in the process of planting pepper, and root rot is a relatively common disease of Zanthoxylum. When encountering root rot, there is almost no way to save the pepper tree, so it is important to prevent the root rot of the pepper. So how to prevent pepper root rot?

First: the drainage work is the best, pepper is afraid of stagnant water every year in April to pay attention to the drainage of the pepper garden, to June and July, the rain increases, and the high temperature weather is more, this time to pay special attention to the drainage of pepper. <>

Second: reasonable fertilization, fertilization rather less than use, if it causes root burning, the entire pepper tree may be burned to death, while applying some farm fertilizer. In this way, many trace elements can be supplemented.

Third: improve the soil, this aspect is also important to pay attention to, whether the soil is loose, air circulation, whether the soil has been acidic. Acidic soil can be neutralized with some lime, and the main thing is to do a good job of tilling.

Fourth: to the pepper seedlings to fade, this step is mainly clear about the harmful bacteria on the pepper, if not removed, if the whole yard is a pepper tree has root rot, then other plants have a high probability of root rot. <>

On the whole, the Zanthoxylum bungeanum tree is prone to root rot, because the root system of the Zanthoxylum tree is relatively developed, and there are many fine roots, and the degree of aggregation is very high, which increases the possibility of bacterial infection, and it is also easy to store more water. Pepper planting does not seem difficult, but the main thing is to pay attention to pests and diseases and root rot. Relatively speaking, root rot is more terrible than pests and diseases, because as long as root rot occurs in peppercorns, then all peppercorns may appear root rot, and once these root rots appear, then there is almost no possibility of **.

In the planting process, the diseased seedlings should be pulled out in time, and the crops should be irrigated with a reasonable root to avoid poor drainage.

The cause of root rot is fungi.

The disease is often similar to the symptoms of the root and is a fungal disease. The pathogen overwinters in the soil and on the diseased residues, generally from late March to early April, and enters the peak period of disease in May, and its occurrence has a great relationship with climatic conditions. Low temperature, high humidity and insufficient light in the seedbed are the main environmental conditions that cause this disease.

The soil in the nursery area is sticky, easy to harden, and poor aeration, which leads to the hindrance of root growth and development, and is also prone to disease. In addition, after the roots are harmed by underground pests and nematodes, there are many wounds, which is conducive to the invasion of germs. In this environment, not only herbaceous flowers that are sown and cut are susceptible, but also woody flowers such as Yueji, Hibiscus, and Hibiscus are also susceptible to diseases when propagated by cuttings, branching, and stripping.

Explain in detail the causes of root rot and how to prevent it.

Waterlogging, low temperature, soil sickness, and bacteria will be caused, so it is recommended to irrigate the roots with a sublime ricke, which can improve the soil, increase nutrients and enhance the tree's potential.

Strengthen the management theory, deeply turn the soil around the pepper tree, enhance the soil permeability, and spray fungicidal and insecticidal pesticides on the soil to prevent and reduce the occurrence of Zanthoxylum pepper root disease. Timely watering and fertilization can enhance the stress resistance of pepper trees and reduce the occurrence of root rot. , often checked, found that the pepper tree is sick, with eight fungus mu with 200 grams of fine soil sprinkled depth of 8 to 20 cm is the best, the diseased pepper tree should be cut out of the diseased roots, away from the pepper garden to destroy, so as to avoid the accumulation of pathogenic bacteria in the pepper garden and infection. In autumn and winter, combined with pruning and fertilization, it can spray fungicides and insecticides on the soil and pepper trees, and can also prevent and reduce the occurrence of root rot.

Root rot is a fungal disease, which generally occurs from late March to early April, and enters the peak period of disease in May, and its occurrence is greatly related to climatic conditions. Low temperature, high humidity and insufficient light in the seedbed are the main environmental conditions that cause this disease.

It can be diluted 1000-1200 times by the resurrection spirit of Zhongwei Happy Forest, evenly sprayed with soil balls before transplanting or watered the root system for a week after transplanting, and then watered thoroughly. It can not only prevent and control root diseases, but also promote the recovery of old roots, germinate new effective roots, and improve the disease resistance and rejuvenation ability of trees.

Root rot is a soil-borne disease of plants caused by fungal bacteria.

Agricultural control: strengthen the management of seedbeds, and the soil covering of seedbeds should not be too thick after sowing.

Physical control: soak seeds in warm water at 55 for 10 minutes.

Pesticide control: seedbed prevention and use root rot net root irrigation, flushing, drip irrigation, irrigation root dilution 1000-1500 times, flushing, drip irrigation dilution 300-600 times, field crops recommended spraying, drenching root use.

Hello, root rot control methods of pepper: 1 agricultural control (1) selected varieties. Select and prepare the seedling plot.

Select high-quality varieties, and soak the seeds + seed coating agent, and sow them at the appropriate time. (2) Implement 3-5 years rotation with leguminous and gramineous crops. (3) Field management.

Intensively cultivate the land, carefully cultivate strong seedlings, try not to hurt the roots when transplanting, carefully tidy up, ensure that the roots are not waterlogged, and apply sufficient base fertilizer. After planting, it is necessary to water in a timely and appropriate amount according to the temperature change to prevent the evaporation of water on the ground and the transpiration of water from the seedlings, and isolate virus infection. It is necessary to spray Kao No. 3 to promote the differentiation of flower buds, more flowering, and more fruit setting.

Pepper was sprayed at the bud stage, young fruit stage and fruit expansion stage to enhance the nutrient matching function of the plant, thicken the fruit pedicle, promote the healthy growth of the pepper body, and enhance the disease resistance. (4) After planting, the temperature is controlled at 20-30, the ground temperature is 25, and the humidity is not higher than 90%. Enables seedlings to thrive.

2. At the beginning of chemical control, spray or water 600 times of 36% thiophanate-methyl suspension, 1500 times of 50% benmonyl wettable powder, 800 times of 50% carbendazim wettable powder, and 500 times of 40% mixed sulfur suspension. 3. The biological control seedbed is sprayed with 300 million cfu Trichoderma canthoxyl powder mixed with water, 2-4 grams per square meter, or 3,000 times the root irrigation after transplanting. It can also be sprayed with 500 times of 2% Ningnanmycin water or 200-300 times of mushroom proteoglycan water.

Prevention and control methods. (1) Artificial control.

Loosen the soil, shade, or cover the rows with grass after rain. In case of high temperature and drought, irrigate water in time to cool down. Flood irrigation should be avoided when irrigating, and drainage should be carried out in time after heavy rainfall.

Before sowing, deep ploughing and application of cake fertilizer should be applied to inhibit the pathogen and reduce the severity of disease by promoting the reproduction of antibiotic bacteria in the soil.

If diseased seedlings are found, they should be uprooted and burned in time. And sprinkle quicklime in the pit to disinfect or replace it with disease-free new soil.

Do not apply unrotted fertilizer in the nursery ground, so as not to increase the soil temperature due to fermentation and hurt the young stems underground, and the unrotted fertilizer is conducive to the activity of saprophytic bacteria, which can induce disease.

2) Pharmaceutical prevention and control, such as soil disinfection, spraying control, etc.

If you saw it off, new sprouts will grow from the roots. There is no need for **.

Summary. Zanthoxylum bungeanum root rot often occurs in nurseries and adult pepper orchards, and is a soil-borne disease caused by a variety of pathogenic bacteria such as Fusarium satiflorum, Pythium, and so on. The onset of the disease generally starts from the root tip and root wound.

The high temperature and rainy season have the fastest onset and great harm. At the beginning of the disease, there were no obvious symptoms in Zanthoxylum bungeanum trees. This disease is mainly preventive, and it is difficult to ** after the onset of the disease.

Root rot and stem rot on Zanthoxylum pepper trees are not a disease.

Hello, root rot and stem rot are not the same.

Zanthoxylum bungeanum root rot often occurs in nurseries and adult pepper orchards, and is a soil-borne disease caused by various pathogenic bacteria such as Sickle, Pythium, and so on. The onset of the disease generally occurs from the apex of the root, the skin chakra of the root wound. The onset of the disease is fastest in the high temperature and rainy season, and the key distribution is also harmful.

At the beginning of the disease, there were no obvious symptoms in Zanthoxylum bungeanum trees. This disease is mainly preventive, and it is difficult to ** after the onset of the disease.

Zanthoxylum bungeanum disease, commonly known as dry rot, is a common disease of Zanthoxylum bungeanum trees, which is related to extensive management and weak tree growth.

It mainly damages the trunk and stem base, and in severe cases, it also damages the branches on the canopy. There are two aspects that lead to the occurrence of gum disease: one is infection.

The second is that mechanical damage, insect pests, frost damage, etc. cause wounds, resulting in glue flow.

Root rot and stem rot on Zanthoxylum pepper trees are not a disease.

Hello, yes. Anyone who grows pepper trees knows that root rot is the most common disease phenomenon. Root rot is most likely to occur during the emergence and maturity of Zanthoxylum bungeanum trees, which can cause corresponding problems in Zanthoxylum bungeanum trees.

Generally, shadows will appear from the root tips, and when the disease is not controlled, the corresponding wounds will gradually spread, which will not only affect the surface of the pepper tree, but also have a severe impact on its essence.
