Actually, a clean cultivation in raised beds is urgent for weeding and proper irrigation.

It's a fungal attack for sure. Use Folicure 25 ml + Asataf 20 gm per 15 ltr of water for foliar spray.

Excess stagnation of water at a particular place followed by heavy 🌞 temperature and humidity favours growth of fungus. It happens with all water sensitive crops and plants. Pruthvi pulses are basically sensitive to excess water therefore don't allow excess water to the pulses. As of now take above suggested spraying. Hope it may help. Take actions fast before the disease damage the crops beyond our control. I saw the image but seems it has done damage to the particular area where water gets stagnant, but if we take above suggested spraying the viral transfer to whole field will stop. Atleast preventive measures need to be taken. Such things happen with soyabean and mung also..
