Fruit rotting in field

Sunburn

Cause: Insufficient bunch shading during prolonged high temperatures. 
Solution: There is no cure for affected fruit. Maintain good canopy cover and ensure bunch covers are applied properly. It may be necessary to pull a leaf down over the bunch for protection. 

 

Affected areas are dark and in later stages are covered by ashy grey spores.

Cigar end

Cause: The fungus Musicillium theobromae (formerly known as Verticillium theobromae). It enters the fruit from the dead floral parts and extends 10 to 20 mm into the fruit. 
Solution: Cigar end is a minor disease and specific control measures are not warranted. 
Bunch ripens prematurely in the field, making the bunch unmarketable.

Mixed ripe

Cause: Various stresses (severe leaf spot, pest damage, water and nutrition) reduce the rate of fruit filling. 
Solution: Improve crop management to limit stresses on the plant.
