What to Do About Celery Seedling Death? Detailed Explanation of Causes and Control Methods

Celery appears on the dining table very frequently and is grown over a very wide range across the country. However, during the growing process, celery seedling death is often encountered in summer. Celery seedling death can seriously affect the growth and development of celery, leading to a major drop in celery yield. It also seriously affects the economic interests of growers. Today, the editor will talk with everyone about the control measures for celery seedling death.

1. Soil disinfection

Celery is a plant that should not be continuously cropped. Continuous cropping of celery makes celery in the second year extremely prone to pests and diseases, seriously affecting yield and quality. Before sowing, various agents should be used to disinfect the soil. For example, formalin can be used. 15-20 days before sowing, use a hoe to loosen the soil. Then mix formalin with water evenly and stir it into the soil. After stirring, cover the soil with film. After one week, the film can be removed, and continue loosening the soil. After half a month, sowing can begin.

2. Seed treatment

When selecting seeds, disease-free seeds should be chosen, or sowing should be carried out in areas where diseases have not occurred. If the seeds are not disease-free, salt water can be used to select seeds and soak out the sclerotia inside the seeds. When foreign matter appears on the water surface, that is the sclerotia of the seeds. At this time, take the seeds out, wash them clean with water, air-dry them, and sow them. In this way, celery sclerotinia disease can be effectively controlled. Seeds can also be placed in warm water at about 50 degrees and soaked, and agents such as thiram wettable powder can be used for disinfection to control damping-off and seedling blight.

3. Field management

Reasonably control planting density. If planting density is too high, field aeration will be too poor, leading to seedling death. After emergence, thin the seedlings immediately to prevent them from shading each other. If there is too much water in the field, it should be drained promptly, and diseased and residual plant parts should be pulled out and taken out of the garden in a centralized manner. When loosening soil and pulling weeds, be careful not to damage celery roots, reducing some manual damage. After harvest, promptly deep-plow the soil and disinfect it to kill pathogens in the soil and reduce the occurrence of pests and diseases.

4. Disease control

Pay attention to celery diseases. Celery diseases generally include a series of diseases such as soft rot, black rot, sclerotinia disease, and seedling blight. The main approach is still prevention, strengthening seed inspection and disinfection. Because most disease occurrences are caused by fungal diseases, explore the patterns and timing of disease occurrence so that corresponding preparations can be made at the time of onset. Diseases generally directly harm the roots, stems, and leaves of crops, causing large yield reductions or even total crop loss.

The above are the methods for how to prevent and solve celery seedling death. Most seedling death is caused by improper management by farmers before and after celery sowing. Ensuring the nutrients and environment needed for celery growth and carrying out crop rotation for more than two years can effectively prevent celery seedling death.
