If we pay attention to the rotten pepper seedlings, we can solve these problems.

The phenomenon of rotten seedlings in pepper must be paid attention to, because it is very likely that pepper blight has occurred. Pepper blight is often referred to as "rotten pepper seedlings", especially sweet pepper is very prone to this disease, and the disease spreads rapidly, which can easily lead to large area damage in pepper fields. Here I would like to share with you the problem of rotten pepper seedlings.

1. The characteristics of rotten pepper seedlings.

Rotten pepper seedlings is the pepper blight, pepper blight occurred in most of the pepper showed dark green spots, showing the shape of water. And the whole growth process of pepper may appear this disease, in the pepper seedling stage infected with this disease, pepper trunk base will generally appear water, branches become dark green, soft rot, until the pepper plant lodging and death. The appearance of this disease in adult pepper is mainly characterized by dark green water in leaves and stems, oil-green leaves, soft and rotten stems, and white plaque in severe cases. Flowers and fruits will also be infected, pepper buds will fall off, pepper fruit color will become dark, soft rotten and so on. Seriously affect the yield of hot pepper.

2. The causes of rotten pepper seedlings.

Pepper blight is caused by fungal infection, the pathogen can survive for a long time, once the environment is suitable, it will invade pepper and cause pepper blight. Especially when the temperature of the pepper planting ground is about 20, the air humidity is about 90%, and the growth of the pepper is relatively weak, and the disease resistance is poor, it is very easy to lead to bacterial invasion. In addition, there is continuous cropping, continuous planting of crops that are more susceptible to the disease, such as zucchini, eggplant, soybeans and other crops, so that the pathogen can be parasitized in large numbers. Unreasonable fertilization, especially some manure, cake fertilizer is not completely mature, resulting in soil bacteria breeding, flood irrigation leading to root rot, etc., will aggravate pepper infection.

3. Treatment of rotten pepper seedlings.

Timely measures must be taken to prevent the spread of the disease in hot pepper which has already occurred. If it is the initial stage, spray 58% metalaxyl manganese zinc wettable powder 600 times, and spray on the surface for about 3 times in a row, each time at an interval of about 4 days.

If the disease is found in the adult period of pepper, the diseased plant must be removed in time, and the cleared pepper root soil must be sprinkled with lime powder, and 75% chlorothalonil 500 times diluent will be sprayed on the pepper plant, and the next spray will be carried out three times in a row after an interval of one week.

4. Preventive measures for rotten pepper seedlings

Pepper seedling rot is mainly to prevent, because the transmission rate of seedling rot is relatively fast, once the epidemic disease occurs, the situation is very difficult to control.

Seeds are purchased through regular channels and then sterilized, which can be soaked in 10% formalin for about half an hour.

The land farming group has a reasonable rotation to avoid repeated cropping and reduce the damage of pathogens. Repeated cropping is not only to avoid repeated cropping of chili peppers, but also to avoid repeated stubble with Solanaceae, soybeans, cucumbers, green onions and so on.

Irrigation and drainage to avoid flooding, wet and rainy weather needs timely drainage to avoid high-temperature stagnant water in the field, resulting in non-decay.

To apply fertilizer reasonably, farm manure must use completely mature fertilizer to avoid root burning, and nitrogen, phosphorus and potassium should be applied reasonably to avoid lack of phosphorus and potassium fertilizer in the land.

The above answers about rotten pepper seedlings come from the original creation of science to promote agriculture. I hope it can be helpful to you. Welcome to add my attention and learn more agricultural information.
