Prevention and Control of eggplant Seedling snap

In the seedling stage of eggplant, it is very easy to get quenching disease, and the disease which is very easy to occur in eggplant seedling stage is an important link in the process of planting eggplant at seedling stage, which is of great significance to increase the yield. So how to prevent eggplant seedling collapse? Let's take a look.

1. Symptoms

Eggplant quenching disease is generally in the early stage of seedlings, many times the seeds will form rotten seeds before they are unearthed, and the cotyledons and true leaves will also be damaged and cause quenching after emergence. After the disease of the seedlings, a yellow-green watery spot appears at the base of the stem, as if it had been scalded by boiling water, which is likely to turn yellowish brown and circle around the stem. The disease will gradually dry rot, and depression, waterlogged symptoms will gradually spread around, drunk caused the seedlings to fall to the ground, withered and lost water, and then withered and died. At the initial stage of the disease, as long as there are a small number of seedlings in the field, it will extend outward a few days later, resulting in the quenching of wheat seedlings. When the humidity is high, white cotton-like hyphae will grow on the surface and adjacent surface of the diseased seedlings.

2. The regularity of the disease

The pathogen overwintered in the diseased body and soil, spread to the wheat seedlings by wind, rain and irrigation under suitable conditions, invaded from the stem base of the seedlings, and the incubation period was 1-2 days. The pathogen can grow under the conditions of high temperature and low temperature, so when the seedling bed temperature is too low, the wheat seedling grows slowly, and the susceptible period is lengthened in the high temperature environment, and it is easy to develop quenching disease, especially in the case of continuous overcast and rainy weather, lack of light and weak growth of wheat seedlings. the disease is serious.

3. Prevention and control methods

Strengthen seedling management, avoid low temperature and high humidity environment, should not be watered in cloudy and rainy days, and select varieties with strong disease resistance according to local requirements. The seeds and soil should be treated with chemicals before sowing to prevent the occurrence of stunting disease. The seedbed should choose diseased blocks with high dryness, shelter from the wind and sun, good drainage and loose and fertile soil. In order to avoid bringing germs into the seedbed, farm manure should be applied after full ripening, and fully turn the sun and rake flat before tillage.

The above is the introduction of eggplant seedling quenching prevention and control methods, hope to help you, want to know more related knowledge, please pay attention to us.
