Spinach is a common vegetable variety in our life. It is said that Popeye eats spinach. People often eat spinach. The benefits are not only to relieve heat and blood, but also to enhance the body's resistance and promote growth and development. In the countryside, there are many people who grow spinach, but what is most afraid of planting is the problem of dead seedlings. Once the death of the seedlings is very likely to cause a harvest, what is the cause of the spinach dead seedlings? How to prevent it?

First, the cause of death

1. Fusarium wilt

Fusarium can cause dead trees. Infected plants will have a dull and dull leaf color, and the mesophyll tissue will be yellowed and the roots will gradually brown and die. When the disease occurs, the plant grows poorly and dwarfs. In the high temperature and high humidity environment in summer, the diseased plants will quickly wilted, yellow leaves and die.

2, heart rot

Heart rot mainly harms the stem base and heart leaf part of the plant. After the onset of the disease, the dead tree phenomenon is very likely to occur. After the seedlings are unearthed, the base of the stem will become brown, contracture, sudden death, rot and other symptoms, leading to dead trees.

3, blight

Spinach seedlings to adult plants will be harmed by this disease. After the disease occurs, it is very easy to die. After the seedlings are unearthed, after being infected by Rhizoctonia solani, the leaves first wilted, the disease continues to develop, and the plants will rot from the roots. Until the fall is dead. After the seedlings are infected, the lower leaves begin to turn yellow until the main roots become black and rot, shrinking and dying.

4, rain watering

In the management of spinach in summer, do not allow rainwater to be poured. Once the rainwater is poured, it is easy to cause dead trees. Therefore, we must pay attention to the management when we manage it, and do not allow rainwater to irrigate the plants.

Second, prevention and treatment methods

The seed is coated with a drug at the time of sowing, and seeding after seed dressing with a chemical agent can prevent a large part of the disease.

1. The occurrence of blight can be controlled by chlorobromo isocyanuric acid solution;

2, heart rot can be prevented by Amishida or iprodione;

3, the occurrence of blight can be controlled by methyl chlorpyrifos EC.

If individual plants occur, the diseased plants should be removed in time, and the diseased spots should be disinfected and sterilized to prevent the spread of germs through the soil.

The above is the reason why the dead seedlings of spinach cultivation and the prevention and treatment methods are compiled by Huinong.com, I hope to help you.
