What is the cause of pepper soft rot? What are the rules of the disease? With the introduction of prevention and control methods!

The planting area of pepper is very extensive in our country. In the process of planting pepper, the phenomenon of rot and deformation of pepper will be found, which seriously affects the growth of pepper and reduces the yield, which is mainly caused by pepper soft rot. So what is the cause of pepper soft rot? What are the rules of the disease? With the introduction of prevention and control methods!

I. the cause of soft rot of pepper

Pepper soft rot is easy to spread in low-lying fields, high density, many borer pests or continuous rainy weather, and high humidity. The pathogen overwinters in the soil with the disease remains and becomes the source of infection at the beginning of the next year. In the field, the pathogen invades from the wound through irrigation water or Rain Water spatter, and after infection, the pathogen can spread through tobacco green insects and wind and rain, so that the disease spreads in the field.

Second, the incidence regularity of soft rot of pepper.

Pepper soft rot is a bacterial disease, the pathogen overwintered in the soil with the disease residue, and with Rain Water and irrigation water spreading in the field, it became the initial infection source of the disease in the field the following year. The pathogen continued to spread through fruit borer and invaded by fruit wound, leading to disease epidemic. Extensive management, low-lying and moist land has a serious incidence, and the overcast and rainy weather will aggravate the occurrence of soft rot.

III. Symptoms of soft rot of pepper

The soft rot of pepper is mainly harmful to the fruit, which mostly occurs on the green fruit. after the disease is infected, the fruit initially appears water-immersed dark green spots, which expands rapidly, the disease spot becomes light brown, the pulp is rotten and smelly, the fruit is deformed, most of the diseased fruits fall off, and a few are left on the branches. after dehydration, only gray pericarp was left on the plant.

IV. Control methods of soft rot of pepper

1. Rational crop rotation

Rotation with non-Solanaceae and cruciferous vegetables for more than 3 years, cultivating strong seedlings, timely planting, reasonable close planting, paying attention to ventilation, plastic film mulching, timely removal of stagnant water in the field after rain, reduction of air humidity, timely removal of diseased fruit and deep burial outside the field, reduce the source of re-infection in the field.

two。 Pest control treatment

Choose a spray of 2.5% kungfu EC 5000 times, 4.5% cypermethrin 3000 times, 2.5% deltamethrin 2000 times, 20% fenvalerate 2000 times, etc.

3. Disease prevention and treatment

After the initial disease and rain, choose either 50%DT fungicide 500x solution or 72% agricultural streptomycin soluble powder 4000 times solution to choose a spray.

The above is the introduction of the soil flow net on the causes and control methods of pepper soft rot, planting management should be done well, and attention should be paid to controlling the application of nitrogen fertilizer when fertilizing, not too much, resulting in pepper growing, reducing permeability and causing pepper leaves to fall.
