The root melting in peas and other pulsable crops is a very important disease, because it affects the yield. This disease mainly affects the roots, due to which the seedlings do not come out properly, there is less growth of plants, and the yield would decrease . Is. Symptoms include buried lesions, roots of brown or black colour, shrinking root system and melting of roots. Even if the lumps come out , small and light coloured , they are less in number. Plants growing from infected seeds wither away shortly after sprouts. Living plants are less green and their vitality is low. Development in infected plants in conditions  is blocked.Opportunist germs nest on rotting tissues , which causes the symptoms to get worsen. In this disease, the entire farm is never affected, but this disease is often packed in the fields, and the affected area increases when there are favourable conditions for germs.


Root rot disease is also known as humid melting disease. Pea crop is very damaged by this disease. But if this disease is managed properly, then along with protecting the plants from this disease, we will also be able to get good quality crops. It is a soil -borne disease. When there is more humidity in the atmosphere, these diseases spread more rapidly. Usually the outbreak of this disease is seen more in small plants. After some time the leaves start shrinking. If the plants are uprooted, their roots look rotten.

Plants affected by tourism point disease becomes dry. This leads to a huge decrease in production. Lakhses are caused by a mixture of poetic bacteria living in the soil that can infect plants in any stage of their growth. Rhizoctonia Solani and Fusarium Solani are part of this mixture like the remaining group, they can live longer in the soil. When the circumstances are favourable, they nest on the tissues of the roots and disrupt the transport of water and nutrients to the upper part of the plant, which is the reason for plants being withering and green. As they grow inside the tissue of the plants, they are often found with these poetry which disrupt the normal growth of the roots and the manufacture of lumps. At the beginning of the season, cold and moist soil is favourable for the development of the disease. Actually, symptoms are often seen more in the areas of water logging. The date of sowing and the depth of sowing also have a profound effect on the release and yield of sprouts.


How to manage root melting disease in peas and other pulses?

Prevention through crop cycle

Crop cycle is a fundamental practice to disrupt the life cycle of pathogens and reduce the risk of root rotting . Avoid planting peas or other pulses continuously in the same field. Instead, cultivate in turn with non-dilute crops to break the disease cycle and reduce the construction of pathogens in the soil.

Soil health management

It is important to maintain the best soil health to prevent root rot. Ensure proper drainage to avoid waterlogging conditions, as excess moisture creates a favorable environment for the development of pathogens. Improvement in soil composition and aeration through the inclusion of organic materials can improve overall health of soil and reduce the pressure of the disease.

Resistant varieties

Selection of resistant varieties to deal with root rot is an effective strategy. Breeding programs have developed varieties with advanced resistance to specific pathogens. Consult local agricultural extension services or seed suppliers to identify and choose varieties of peas and pulses crops displaying immunity to root rot pathogens prevalent in your area.

Seed treatment

Treating seeds with fungicides before planting is a preventive measure to prevent pathogens produced from soil. Fungi seed treatment can provide a protective barrier, which prevents the initial infection of the roots. Follow the recommended application rates and guidelines to ensure appropriate seed treatment without compromising seed viability.

Proper irrigation

Water management is important to prevent root rot. Applying a controlled irrigation system that prevents excessive water filling and ensures similar moisture distribution, helps create less favourable conditions for pathogen proliferation.

Biological control

Biological control involves using beneficial microorganisms to suppress the development of pathogenic fungi. Some bacteria and fungi act as anti -opposition, which prevent the development of root rot pathogens. Applying bio -pesticides or inclusion of beneficial microbes in the soil can contribute to make the root area of the crop healthy. Dissueing 10 grams per liter of Trichoderma by dissolving it in water (soil borne disease ), Such as can be done to control the rotting of the roots of pulses. In addition, it improves the growth and productivity of survived plants.

Cleanliness measures

It is necessary to adopt good hygiene in the area for disease management. Remove and destroy the residues of infected plants immediately to prevent the manufacture of inoculum. Clean the equipment and tools thoroughly to protect the contaminated soil from spreading into untouchable areas

Nutrient management

It is important to maintain proper nutrient levels for plant health and flexibility towards diseases. Ensure that peas and pulses crops do not get enough but excessive nutrients, because imbalance makes the plants more sensitive to root rot. Perform regular soil testing to monitor the level of nutrients and adjust fertiliser practices accordingly.

Surveillance and quick detection

Regular region monitoring is important to detect early symptoms of root rot. Pay attention to withering, yellowing, or stagnant growth, which are common symptoms. Early detection allows quick intervention, which reduces the effect of the disease on crop yield. Consider implementing scouting programs and using clinical equipment to identify potential issues.

Chemical control

If root rot in the field is already established, chemical control is considered the last resort. Funghels labelled for root rot control can be used, but this approach should be adopted in a judicious manner keeping in mind the environmental and economic factors. Treatment of soil by dissolving 2 grams per liter of fungus called Roco M or Carbendazim causes a huge decrease in the fierceness of Soil Drenching. Consult local agricultural experts or expansion services for guidance on proper chemical control measures.


Summary

The management of root rot in peas and pulses crops requires a multifaceted approach that combines preventive measures, cultural practices and, if necessary, targeted interventions. By including these strategies in an integrated insect management plan, farmers can reduce the effect of root rot, protect the health of the crop and continuously increase overall crop productivity.
