Deformed or variegated fruit Mokillo Cause: The bacterium Pseudomonas sp. It occurs naturally on flowers and may be transferred to other flowers by insects. Frequently only one finger per hand is infected. The problem is more prevalent in the wet season. Solution: Control is not warranted.More images Tissue-cultured off-type Cause: A genetic abnormality occurring in tissue-cultured plants.Solution: Destroy affected plants and set additional following suckers on nearby plants. Fruit are usually short, straight and darker green. Cold weather Cause: Temperatures below 6°C lead to abnormal growth. The more hours of exposure and the lower the temperature, the greater the damage.Solution: Very early bunch covering before bract lifting will raise the bunch temperature by 1 to 2°C. November dumps Cause: Bunch initiation coinciding with night temperatures below 6°C in winter. These bunches normally emerge in October and November.Solution: Seldom a problem in north Queensland. Plant crops are affected more than ratoons, so time planting to avoid bunch initiation during mid-winter. Genetic abnormality (variegated fruit) Cause: A genetic abnormality that occurs in tissue-cultured plants.Solution: Destroy affected plants and set additional following suckers on nearby plants.
