How to prevent and cure cucumber gum disease? Cucumber seed disinfection, agricultural chemical control

Cucumber gum disease, also known as cucumber bacterial stem soft rot, is one of the more common diseases in cucumber planting. It has the characteristics of rapid spread and difficult control, and white-like fungus pus will appear at the beginning of dyeing. Gradually spread the cultivation of cucumber rot, so it is necessary to prevent and control in time, then how to prevent and cure cucumber gum disease?

First, the symptoms of cucumber gum

1. Flow glue caused by bacterial diseases

The melon on the vine will appear white-like fungus pus, similar to the coagulation state, so the wound at the pus is not very obvious, the inside of the melon bar is necrotic and rotten, and accompanied by odor.

2, the flow of glue caused by fungal diseases

Fusarium wilt is easy to appear on the stems, and the diseased melon strips will appear dark green depressions, while anthracnose and blight will appear on the melons or stems, and the glue will be yellow.

3, physiological diseases and operation caused by glue

The melon strip on the vine has a white transparent and slowly turns yellow, which is prone to the growth of the plant or a large amount of watering.

Second, the prevention and treatment of cucumber gum disease

1. Seed disinfection

Since seed-borne bacteria is one of the main primary invasive sources of gum disease, it is necessary to effectively do seed disinfection measures to reduce the disease from the most fundamental, and the grafted rootstock can also be infested, so the rootstock seeds should also be taken. Seed disinfection measures.

2, disease-free soil nursery

When planting cucumbers, choose the seedlings that have been sterilized, or use the field soil that has not been planted with vegetables, configure the decomposed farmyard manure as the nutrient soil, and choose the cucumber seedlings that have not been contaminated by vegetable residues.

3. Rotation or soil disinfection

On the planting land, it is necessary to choose a dry land, good drainage, ventilation and planting other melon and solanaceous vegetable land. In the summer vegetable replacement period, solar energy, organic fertilizer and straw can be used for high temperature disinfection of the soil. It is also a way to reduce the amount of soil bacteria. Before the planting, the amount of 1kg of 77% copper sulphate WP can be evenly applied per acre, which can be sprinkled in the planting ditch or in the planting hole. After planting the soil, it can be planted.

4. Agricultural control

Agricultural control can choose the cultivation method of dark mulching under the high mulch film. If conditions permit, you can also choose the irrigation method of drip irrigation, clean the garden regularly, and ensure the field hygiene. In the greenhouse, special rubber shoes are required. Due to the large temperature difference between day and night, the temperature is reduced, the humidity is controlled, the humidity in the greenhouse is large, and the dew is large in the morning. The pruning, snoring, vines and picking operations can be appropriately reduced, and the field operation can be avoided not only to avoid walking with the shed. It can also effectively control the spread of disease in the field.

5, chemical control

In the colonization, the drug is colonized, and the root is planted with 77% calcium sulphate WP WP 400-500 times. In the early stage of cucumber gum disease, 3% carbendazim WP can be selected 800-1000 times or 2% spring seromycin 500 times liquid for prevention and control, the main operation is: spray every 5-7 days, continuous spraying three or four times, if the control effect is not obvious, you can increase the number of spraying, also In the early stage of the disease, you can use 20% thiabend copper suspension 500-700 times solution or 77% copper hydroxide wettable powder 1000 times solution, spray once every 7-10 days, spray two or three times continuously, here Remind that in the prevention and treatment of chemicals, it is best to choose to rotate, which can delay the emergence of drug resistance.
