Raised blisters start appearing in the vines affected by Gummosis disease. After some time these blisters turn into sores. As the disease progresses, brown gum is secreted from these blisters. The number of flowers and fruits decreases in the vines affected by this disease.
Control: Use fertilizers and nutrients in balanced quantities to increase the immunity of plants. To prevent the spread of the disease, pluck and destroy the affected parts. Do not leave crop residues affected by the disease in the field. Remove the affected residues from the field and destroy them by burning them. Avoid water logging in the field. Make proper arrangements for drainage.
If the disease appears, spray M-45 (Mancozeb 75% WP) 400 gm/acre or Jatayu (Chlorothalonil 75% WP) 400 gm/acre mixed in 200 litres of water.
