Detailed Explanation of the Causes of Spinach Seedling Death and Control Methods

Spinach is rich in nutrients and also has the effect of stopping bleeding and nourishing the blood. Regular consumption can also enhance the body's resistance and promote growth and development. It is precisely because of these benefits that it is relatively common on our dining tables. However, when growing it, the most feared problem is seedling death. Once seedling death occurs, it is very likely to cause total crop failure, so what causes spinach seedling death? Let's take a look at the detailed explanation below.

I. Causes of Seedling Death

1. Fusarium wilt

Fusarium wilt can cause plant death. Infected plants show dull, lusterless leaf color, yellowing of the mesophyll tissue, and the roots gradually turn brown and die. When the disease occurs, the plants obviously grow poorly and are stunted. In summer under high temperature and high humidity, diseased plants quickly wilt, develop yellow leaves, and die.

2. Heart rot

Heart rot mainly harms the stem base and heart leaf parts of the plant. After the disease occurs, plant death is very likely. After the seedlings emerge, the stem base turns brown, constricts, suddenly dies, and rots, leading to plant death.

3. Rhizoctonia rot

Spinach from the seedling stage to the mature plant stage can all be harmed by this disease, and after the disease occurs, death is very likely. After the seedlings emerge, once infected by Rhizoctonia solani ·, the leaves first wilt, and as the disease continues to develop, the plant begins to rot from the root system until it lodges and dies. After larger seedlings are infected, the lower leaves begin to turn yellow until the main root turns black and rots, shrivels, and dies.

4. Rainwater irrigation

When managing overwintering spinach, be sure not to let rainwater irrigate it. Once rainwater irrigation occurs, it is very likely to cause plant death. Therefore, during management, be sure to pay attention, take good rainproof measures, and do not let rainwater irrigate the plants.

II. Control Methods

When sowing, carry out chemical seed coating on the seeds. After dressing the seeds with chemicals, then sow. This can prevent the vast majority of diseases. For Fusarium wilt, chlorobromoisocyanuric acid solution can be used as a root drench for control; for heart rot, amisulbrom or iprodione can be used for control; for Rhizoctonia rot, tolclofos-methyl emulsifiable concentrate can be used as a root drench for control. If only individual plants are affected, promptly remove the diseased plants and thoroughly disinfect and sterilize the diseased planting holes to prevent the pathogen from spreading through the soil.
