The latest cause of Cucumber death and its Control measures

In the process of planting cucumber, there is often the phenomenon of dead trees, which brings huge losses to growers, so what is the cause of dead cucumber trees? How to prevent and cure it? Let's take a look at the detailed introduction with the editor.

1. Fertilizer damage

The application of immature farm manure during fertilization will cause it to emit a large amount of heat during decomposition, resulting in root burns and dead trees, or a high concentration of chemical fertilizer, especially in the seedling stage, the root system has not yet grown, and the application of thick fertilizer will lead to the death of the root system.

Control measures: the application of completely mature fertilizer, farm manure and organic fertilizer must be fully fermented before application, pay attention to the concentration of chemical fertilizer, can be diluted with water, and the method of flushing application should be adopted.

2. Stagnant water retting root

In continuous rainy weather or sudden sunny weather after rain, it will lead to cucumber deformity, if the time is too long, it will lead to death. In addition, retting roots at the seedling stage will also cause dead plants. When the seedling bed or planting is overwatered or the soil moisture is high, the roots will rot, making the aboveground parts withered until the dead trees.

Prevention and control measures: pay attention to water management, in continuous rain or sudden sunny after rain, to gradually see the light, when the occurrence of withering should be timely shading and replenishing water. When watering, we should pay attention not to flood irrigation, we can use a small amount of water frequently.

3. Freezing injury

When cucumbers encounter a low temperature of minus 10 degrees Celsius, there will be a good belt, and many farmers will often prepare to sow seeds because of the high temperature in winter for many years. When they encounter low temperatures, they will not be able to defend themselves in time, resulting in freezing damage to trees.

Prevention and control measures: protective measures should be taken in the period of low temperature, such as increasing light and reducing ventilation to increase the temperature in the greenhouse and avoid plant freezing injury.

4. Diseases and insect pests

Many kinds of diseases and insect pests of cucumber will cause death. Most of the dead plants in seedling stage are caused by quenching disease and blight, and most of them are caused by Fusarium wilt, blight, root rot, vine blight, root nematode disease and so on.

Control methods: select the varieties with strong disease resistance, find that the diseased plants should be pulled out and taken out of the field in time, and then disinfect the disease points, and at the same time comprehensively spray chemical control.

The above is the introduction of the causes and control measures of cucumber death. I hope it can help you. If you want to know more about it, please follow us.
