Eggplant is a common vegetable in life and a vegetable that people prefer to eat. However, eggplant disease can cause a large area of ​​death in the seedbed, causing serious damage to the growth of eggplant.

Eggplant sickness symptoms

Eggplant seedlings are prone to collapse. At the initial onset, the base of the stem of the seedling was soaked in water, and then the diseased part became yellowish brown, and soon the contracture became linear, and the disease developed rapidly. Before the cotyledon had not withered, the seedlings fell into pieces. Serious damage caused by destructive seedlings.

The incidence of eggplant disease

The pathogens overwinter with the diseased bodies in the soil. When the conditions are appropriate, they are spread to the seedlings by rainwater or irrigation water, and invade from the base of the stems, and the incubation period is 1-2 days. The pathogen enjoys a high temperature of 34-36 ° C, but it can also grow under the low temperature condition of 8-9 ° C. Therefore, when the temperature of the seed bed is low, the seedling grows slowly, and when it encounters high humidity, the susceptible period is elongated and it is easy to trip. Disease, especially in the seedling period, there is continuous rainy weather, insufficient light, and the seedlings grow weak and seriously affected. If the cold seed is infested during the nursery period, if you do not pay attention to the wind, it will aggravate the occurrence of the disease. When the seedling cortex is corked, the true leaves grow and gradually enter the disease resistance stage.

Eggplant disease prevention and treatment method

1 Adopt rapid seedling or soilless seedling raising method to strengthen the management of seedbed bed. See if the seedlings are properly released in the wind, avoid low temperature and high humidity conditions, and do not water in rainy days.

2 Select anti-smash disease varieties according to local requirements.

3 agents treat seeds and soil. The seeds were soaked in a 500% solution of 53% fine nail cream and manganese zinc water dispersing granules for half an hour, with a liquid germination or live broadcast. Take the sieved nutrient soil 50 kg plus 68% fine nail cream · manganese zinc water dispersing granules 20 g, add 2.5% fluroxynitrile suspending agent 10 ml, mix well and then add nutrients or spread on the nursery. Or use 68% fine nail cream · manganese zinc water dispersion granule 600 times liquid or 69% manganese zinc enoyl WP 600 times liquid soaking seedling tray or watering control effect is good.
