If you want to prevent and control the wilt of melon, you should start from the soil turning, fertilization control and seedling treatment, etc., the soil should be often turned to ensure that it is soft and breathable, and raw fertilizer or thick fertilizer can not be used when fertilizing, and the seedlings of rotation should be pulled out in time to avoid polluting the land, and timely prevention to avoid plant disease.

1. Turn over the soil

If you want to prevent and control the wilt of melon, it is necessary to ensure that the soil where it is located will not be abnormal, the soil is excessive, long-term drought, or the soil is too viscous and acidic, will lead to the increase in the probability of melon infection with wilt, so it is necessary to regularly adjust the soil to make it soft and breathable, loose and porous.

2. Fertilization control

Melons infected with wilt, may also be caused by improper fertilization, fertilization should use ripened thin fertilizer, if it is fertilized when using unripened fertilizer, so that the raw fertilizer in the soil releases high heat burns the plant, or the fertilizer breeds a large number of germs, etc., it will lead to plant infection.

3. Seedling treatment

The treatment of seedlings is also more important work, because melon is an annual plant, so every year after harvesting, the old vines should be uprooted in time, and the soil should be turned to ensure that the root part is also removed, otherwise the residual part of the plant will rot in the soil, which will cause a large number of germs and make the newly planted plants infected with diseases.

4. Details of the disease

Melon wilt is a plant disease caused by fungi or pathogens, which is characterized by the rapid onset of the disease and is very soilly, which can cause severe spotting of the plant, withering of the leaves, and the loss of fruits and flowers, and can also cause the peel of the melon to be damaged, so that the whole plant dies completely before the fruit is ripe.

Agriculture is an industry that produces food and industrial raw materials through the cultivation of plants and animals. The Nongqiao slow air industry belongs to the primary industry, and the science of agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves.

We refer to the various departments that use the laws of growth and development of animals, plants and other organisms to obtain products through artificial cultivation as agriculture. Agriculture provides basic products that support the construction and development of the national economy.

1.Patterns of occurrence.

The pathogen latent on the diseased tissues and remain in the soil for overwintering, and the following year produces conidia for initial infection. The meristem released after the plant is infected is spread by wind and rain and is re-infected. In mid-July, the temperature is 20 to 30 degrees Celsius, and the incubation period is 3 to 5 days.

Conidia propagate from plant to plant at a distance of 6 to 8 meters. There were obvious differences in disease resistance among melon varieties: in general, thin-skinned crispy melons belonged to the disease resistance system, with low incidence and strong disease resistance; Thick-skinned melons are more susceptible, especially thick-skinned melon reticulated series and cantaloupe.

The germ develops at a temperature of 20 to 30 degrees Celsius, with a maximum of 35 degrees Celsius and a minimum of 5 degrees Celsius, and 55 degrees Celsius after 10 minutes of death. It has been observed that the average temperature for 5 days is above 14 degrees Celsius and the relative humidity is higher than 55 percent. Temperatures of 20 to 25 degrees Celsius can be prevalent.

Within the appropriate temperature range, the humidity is high and the disease is severe. The number and amount of rainfall during cultivation determine whether the disease occurs and becomes prevalent. The disease is severe under the conditions of continuous cropping, overlapping canopy closure of vines in densely planted fields, and flood irrigation.

2.Prevention and control methods.

Choose disease-resistant varieties. Choose varieties resistant to vine blight such as Longtian No. 1, and also choose early-maturing varieties such as Elizabeth and Xinmiza. Agricultural measures.

Crop rotation of 2 to 3 years is practiced. Adopt high furrow or ridge planting, strict and prohibit flood irrigation, to prevent the spread of the disease in the field. Reasonable dense planting, using the scaffolding method to cultivate, this method can change the ecological conditions of melon fields and reduce the occurrence of vine blight.

Pruning and beating in time, and finding diseased plants are uprooted in time and brought to the field for deep burial or burning. Formula fertilization technology is used to apply fully decomposed organic fertilizer. Pharmaceutical prevention and control.

At the beginning of the disease, spray 1000 times of 20% Ricketta wettable powder, or 500 times of 40% seed dressing double powder, or 500 times of 80% Xinwansheng wettable powder, etc., at the base of the stem or the whole plant, and spray 1 time every 8 to 10 days, a total of 2 to 3 times. When cultivating in sheds, 5% of the anti-black mold dust agent can be sprayed, and 1 kg per mu can be used. Shed cultivation can also be smoked, with 45% bacteronia smoke, according to the dose of 80 grams per mu, once every 7 days, continuous control 2 to 3 times.

Mixing the same amount of water with anti-decay and healing powder to make a paste and apply the diseased parts on the vine can also effectively prevent the spread of germs.

Prevention and control measures of melon wilt: (1) Agricultural control.

Choose a plot with high terrain and convenient irrigation and drainage for planting. Crop rotation with non-melon crops can reduce disease. Apply well-rotted organic fertilizer, appropriately increase phosphorus and potassium fertilizer, and control the amount of nitrogen fertilizer. Clean the fields and burn the sick and depraved outside the fields.

2) Physical control.

Dry watermelon seeds and treat them in a 70 degree Celsius incubator for 72 h. Soak seeds in warm water at 55 degrees Celsius for 20-30 minutes.

3) Pharmaceutical prevention and control.

40% formaldehyde 150 times liquid soaking for 1 2 hours, wash and dry for sowing. Prepare 50% carbendazim wettable powder 1000 times liquid soak seeds with warm water at 50 60 degrees Celsius for 30 40 minutes, wash and then germinate and sow seeds. Chemicals treat the soil.

Use 50% carbendazim wettable powder per 667 meters 23 5 kg, mix 200 kg of soil, evenly cover the seeds or apply them to the planting hole. At the beginning of the disease, immediately irrigate the roots with 50% carbendazim wettable powder 500 times, or 2% pesticide antiseptic 120 water solution 200 times, kilograms per plant, and control 1 3 times.

You search for Guangdong Lihao Biological Agriculture, there is an article on the prevention and control of melon wilt, you can go and take a look, and after reading it, Xiaobai can grow melons. As long as he uses microbial technology to solve the problem of blight, it is simple to apply and effective!

Melon wilt disease is also known as vine cutting disease and wilting disease, commonly known as "seedling disease, dead seedling disease.""It can occur throughout the growth period, with the most severe disease occurring from flowering to fruiting. Disease after sowing and before soil can cause seed rot. The fibrous roots of the seedlings are reduced, the leaves are shriveled, wilted and yellowed, lodging and die, and the stem base is pale yellow.

At the adult stage, the diseased plant grows slowly, and the leaves gradually wilt from the bottom up, especially at noon.

You can use Demer's earth-borne nemesis to prevent and control earth-borne diseases such as Verticillium wilt, brute blight, standing blight, and root rot.
