Sirohi Papaya Farmers Face Monsoon Stem Rot Risk as Expert Outlines Crucial Crop Protection Steps

In Sirohi district of Rajasthan, waterlogging during the monsoon season has heightened the risk of root and stem rot in papaya orchards. Dr. Kamini Parashar, a subject specialist at the Krishi Vigyan Kendra, has advised growers to ensure proper drainage, organic compost treatment, and timely fungicide application.

Sirohi district in Rajasthan holds a prominent position in papaya cultivation across the state, with farmers growing high-yielding varieties such as Red Lady alongside several other cultivars. However, the arrival of the monsoon season brings significant challenges for local growers due to water stagnation in orchards. Excessive accumulation of rainwater around plants triggers root and stem rot disease, posing a severe threat to crop yields and the financial stability of farming households.

Understanding Root and Stem Rot Triggered by Waterlogging
Dr. Kamini Parashar, a subject specialist at the Sirohi Krishi Vigyan Kendra, explained that prolonged water accumulation in fields during rainy periods serves as the primary driver of root and stem rot. Stagnant water around the base of the plant creates favorable conditions for fungal pathogens to thrive, severely damaging the root structure and causing the main stem to decay. Infected plants rapidly begin to dry up and fail to set healthy fruit, leading to substantial yield losses if the condition remains unchecked.

Ensuring Proper Drainage and Managing Irrigation
To protect papaya plantations from heavy damage, Dr. Kamini Parashar urged farmers to implement immediate preventive measures in their fields. Establishing a robust drainage system throughout the orchard is vital to ensure that rainwater flows away quickly and does not puddle around plant trunks. Additionally, because environmental and soil moisture levels remain elevated during the monsoon, routine irrigation is unnecessary. Farmers should wait until the topsoil has dried out completely before applying any further water to the crop.

Sanitation, Organic Solutions, and Fungicide Application
Field sanitation plays a crucial role in preventing the disease from spreading to healthy crops. If any plant exhibits symptoms of infection, it should be immediately uprooted and destroyed outside the cultivated area. Growers are also advised to select certified disease-free, healthy saplings during fresh planting operations. For biological disease management, mixing Trichoderma-treated manure or compost manure into the soil offers effective protection. Should signs of the disease appear in the field, prompt consultation with agricultural specialists for spraying appropriate fungicides can curb the infection early and prevent severe economic losses.

What this means for you
• Across India: Papaya cultivators across the country can prevent heavy financial losses from root and stem rot by maintaining efficient drainage systems during monsoon.
• In Rajasthan (Sirohi): Farmers in Sirohi growing Red Lady and other varieties need to adopt Trichoderma compost and timely fungicide sprays to protect their yield.

Frequent irrigation is unnecessary during monsoon. Farmers should irrigate only after the topsoil has completely dried out.

3. What action should be taken if a papaya plant shows symptoms of rot?
Infected plants should be immediately uprooted and destroyed outside the field to prevent the disease from spreading to healthy crops.

4. What biological method helps control root and stem rot in papaya?
Applying Trichoderma-enriched manure or compost manure to the soil provides effective biological protection against the disease.

5. Which papaya variety is prominently cultivated in Sirohi district?
