Dry root rot: Rhizoctonia bataticola/Macrophomina phaseolina

Symptom
The disease appears from flowering to podding stage as scattered dried plants. The leaves and stem are become straw colored. Affected plants wither and spread across the entire field. The roots of infected plants become brittle and dry. Management Deep ploughing in summer Grow cultivars resistant to dry root rot. Drought should be avoided. Sowing should always be done on the recommended time. Germinating and young seedlings should be saved from high temperatures. Seed treatment with T. viride @4g/kg or P. fluorescens @ 10g/ kg of seed or Carbendazim or Thiram 2g/kg of seed. Spot drenching with Carbendazim 1g/lit or P. fluorescens / T. viride 2.5 kg/ha with 50 kg FYM.
