A fellow banana farmer recently told me of an infestation of the Bunchy Banana Top Virus in Hilo.

I drove by to look and sure enough, most of the bananas at that site were infected.

If you see this symptom on banana plants, please call Kyle Onuma at the State of Hawaii’s Department of Agriculture.

From the Cooperative Extension Office, College of Tropical Agriculture & Human Resources of the University of Hawaii at Manoa:

Banana bunchy top virus (BBTV) is one of the most serious diseases of banana. Once established, it is extremely difficult to eradicate or manage. BBTV is widespread in Southeast Asia, the Philippines, Taiwan, most of the South Pacific islands, and parts of India and Africa. BBTV does not occur in Central or South America. In Hawaii, BBTV was first observed in 1989 and is now widely established on Oahu. In 1995 it was discovered in the Kona area of the island of Hawaii, and in 1997 it was found on the island of Kauai.

The virus is spread from plant to plant by aphids and from place to place by people transporting planting materials obtained from infected plants. There is no cure for BBTV. Some banana varieties, like the Cavendish types, are more readily infected with the virus, but no variety of banana is resistant. Banana plants that show symptoms rarely bear fruit, and because they are reservoirs of the virus, they must be destroyed. BBTV is a serious threat to Hawaii’s banana industry and to the productivity of banana plantings in home gardens…. Read the rest here

Banana Bunchy Top is a very serious banana virus. It adds another layer of cost to banana farming.

We need to renew our vigilance.
