Common celery diseases: symptoms of heart rot and leaf margin rot, and how to prevent and treat tipburn

Tipburn in celery is a common physiological disease when growing celery. Its main cause is calcium deficiency in the plant. In severe cases, it causes the heart leaves to rot, seriously affecting the quality and yield of celery and reducing farmers' income. So how should celery tipburn be prevented and treated? Let's take a look at the detailed introduction below.

1. Symptoms of tipburn

Tipburn is also known as heart rot. It mainly harms the heart leaf area. When the disease occurs, the growing point of the heart leaf turns brown, then gradually spreads, causing the heart leaf to wither and scorch dry. As the disease develops, the root crown of the celery will also die one after another. This phenomenon is generally rarely seen in the early stage of growth, and mainly occurs when the plant has 11-12 leaves and the heart leaf is growing.

2. Causes

This is one of the three major physiological diseases during celery growth. The main cause is calcium deficiency in the plant. A lack of calcium and boron elements in the soil causes the plant to lack these nutrients; when the salt concentration in the soil is relatively high, it affects the celery root system's absorption of calcium; in addition, when the soil is too dry, and when nitrogen fertilizer is applied excessively, it also inhibits the root system's absorption of calcium. All of these causes may lead to celery tipburn. After tipburn occurs, if the environment is humid, the heart leaf will become infected and rot.

3. Prevention and treatment methods

Scientific formula fertilization should be adopted, and the levels of nitrogen, phosphorus, potassium and other trace elements in the soil should be reasonably regulated to ensure balanced nutrients for the plant. Choose non-saline-alkali land with relatively high and dry terrain for planting. Flood irrigation should not be used. Apply more farmyard manure or organic fertilizer and less chemical fertilizer. Take cooling measures during high-temperature periods. When raising seedlings, the soil must undergo strict disinfection measures. When the disease occurs, promptly remove diseased leaves or diseased plants, take them out of the field and burn them, spread quicklime on the diseased planting holes, and spray a low-concentration calcium nitrate solution.
