The Central Plantation Crops Research Institute (CPCRI), Kasaragod, recently issued an advisory to farmers to control ‘kole roga’ (fruit rot disease) in arecanut plantations.
About Fruit Rot Disease:
It is a plant disease that can cause significant losses for farmers, as it can reduce the quality of the crop and make it unmarketable.
In some cases, fruit rot can also lead to the death of the plant.
It is caused by a number of different fungi, bacteria, and viruses, and it can be difficult to prevent and treat.
Continuous heavy rainfall coupled with low temperature (20 to 23 °C), high relative humidity (>90%), and intermittent rain and sunshine hours favour the occurrence of fruit rot.
Symptoms:
Brown or black spots on the fruit
Softening of the fruit
Shrivelling of the fruit
Mould growth on the fruit
Many different types of fungi can cause fruit rot, but the most common type is Botrytis cinerea.
This fungus affects a wide range of fruits, including grapes, strawberries, tomatoes, and peppers.
The fungus enters the plant through wounds in the leaves or fruit lesions, and it proliferates in humid conditions.
Once established, the fruit infections can spread rapidly through the crop, causing rot.
The fungi that cause fruit rot can also produce toxins that are harmful to humans and animals.
