Symptoms and control of anthracnose disease in soybean

Symptoms and control of anthracnose disease in soybean
  • Irregularly shaped spots appear on the pods of infected plants. This disease is usually seen on the stem of soybean, at the time of maturity. Anthracnose causes the death of soybean tissue. The disease usually infects the developing stem and leaves. Its symptoms can be seen as various coloured spots or lesions (blight) on leaves, stems, fruits, or flowers, and some infections also occur in the form of cankers on twigs and branches. The severity of infection depends on both the causative agent and the species infected.

  • The spread of disease should be prevented by keeping the fields clean and adopting proper crop rotation.

  • Treat the seeds with Carbendazim 12% + Mancozeb 63%WP @ 2.5 gm/kg of seed.

  • To control this disease, spray Mancozeb 75% WP @ 500 gm / acre or Chlorothalonil 75% WP @ 400 gm/ acre or Hexaconazole 5% SC @ 400 ml / acre.

  • Use Pseudomonas fluorescens @ 250 gm/acre or Trichoderma viride @ 500 gm/acre as biological treatment.
