Introduction

Fusarium wilt, also known as vascular wilt, is a significant fungal disease affecting redgram (pigeon pea) plants. It is caused by Fusarium oxysporum f. sp. udum, a pathogen that specifically targets pigeon peas. This disease is renowned for its ability to infect through the roots and colonize the plant's vascular system, disrupting water and nutrient transport. Fusarium wilt poses a considerable threat to redgram crops worldwide, impacting yield and overall plant health.

Symptoms

Initial stages it is observed that gradual wilting and yellowing of lower leaves, spreading upwards over time. As the disease progresses, affected plants display stunted growth and may develop brown discoloration in their vascular tissues. When stems are split open, dark streaks or discoloration can be seen in the vascular bundles. Infected plants typically do not recover with proper irrigation and nutrient application, resulting in substantial yield losses if not addressed promptly.

 

Preventive measures

To control Fusarium wilt in redgram, use resistant varieties and rotate with non-host crops to disrupt the disease cycle. Before planting, consider soil solarization to reduce fungal numbers. Keep soil moisture optimal and avoid waterlogging, which can favor fungal growth.

 

Chemical control

Amistar Fungicide is the best fungicide for increase in the yield and quality of the crop. It  contains Azoxystrobin 23% SC It will kills the broad spectrum of diseases on various crops. It shows good crop safety, disease control, and maintenance of green leaf area. Amistar Fungicide should be applied at the flowering stage of the crops for better efficacy and enhanced productivity.The recommended dosage is 200ml/acre.

Ridomil Gold Fungicide is a powerful solution for protecting crops from fungal diseases. It combines Metalaxyl (4%) and Mancozeb (64%), each with distinct modes of action. Metalaxyl works by inhibiting protein synthesis through interference with ribosomal RNA production. Meanwhile, Mancozeb provides multisite contact activity, enhancing its effectiveness against soil-borne oomycete diseases. This fungicide is particularly effective in the seedling and nursery stages, offering easy application and systemic uptake for comprehensive crop protection. The recommended dosage is 1000gms / acre.
