Two fungi are associated with this disease viz. verticillium theobromae (V.theobromae) & Trachyspaera fructigena (T.fructigena). The fungus attacks at the flowering stage and its incidence is spotted during rainy season. Spray of Bavistin @ 1 gm/lt or Kavach (Chlorothalonil) @ 1gm / lt of water on the bunches is recommended.:
  •   As the fruit develops, the infection spreads slowly along with the fruit growth  causing blackening of the skin. 
  •   Tip of the infected fingers later gets covered with a powdery mass of spores resembling grey ash end of a cigar. 

  • Removal the untransformed flowers after the finger emergence. 
  • Spray the bunches with Bavistin @ 1 gm/lt or Kavach (Chlorothalonil) @ 1gm / lt of water once in 15 days and later on cover the bunches with polythene sleeve.

    Some more suggestions for a infection free field:

    1. Keep your banana plants as clean as possible.
    2. Collapsing, dying and dead leaves, need to be removed from plants at regular intervals during the rainy season to reduce fungal inoculum levels.
    3. Bury the infected plant parts in a field where Banana is not the present or future crop. Heap and burn the infected plant parts in a banana-free field.
    4. If there is a heavy infestation, use baking soda spray instead of using fungicides which are expensive and also an environmental hazard.
    To control the fungal infection using baking soda: Baking soda is effective in killing the fungal spores, prevention and cure of the cigar end rot disease.
    - Dissolve 100gms of baking soda with 50 gms soap in 2 litres of water.
    Spray the above solution on infected bunches and on the neighbouring bunches to prevent spreading to other plants. Baking soda increases the surface ph of the fingers making it unsuitable for fungi growth.

    Baking Soda Spray:
    Baking Soda spray can be used to control anthracnose, early tomato blight, leaf blight and spots, powdery mildew, and as a general fungicide.
    Sodium bicarbonate commonly known as baking soda has been found to posses fungicidal properties. It is recommended for plants that already have powdery mildew to hose down all the infected leaves prior to treatment. This helps to dislodge as many of the spores as possibly to help you get better results. Use as a prevention or as treatment at first signs of any of the diseases.
    To make: Mix 1 tablespoon of baking soda (It takes three teaspoons to make a tablespoon or approx 20 ml to 25 ml capacity), 2 and 1/2 tablespoons of vegetable oil and 5 ml of Wetting/spreading agent with 4 liters of water. Shake this up very thoroughly. Be sure to agitate your sprayer while you work to keep the ingredients from separating. Cover upper and lower leaf surfaces and spray some on the soil. Repeat the spray after 5-7 days if needed.

     Do not use Baking powder in place of Baking soda.
     Baking soda without oil is ineffective against many diseases.
     Please also note that Sodium Bicarbonate (Baking soda) when used with oil will lead to build up of harmful sodium component and become toxic to plants.
     It is to better to use Ammonium Bicarbonate or Potassium Bicarbonate since they provide Nitrogen and Potassium to the plants.

    Fish Oil Rosin Soap is a good organic insecticide which can also be added @ 25gm per litre with the above 'Baking Soda spray mixture" to enhance its over all efficiency.
