 * BBTV**__**Banana Bunchy Top Virus**__



**__HOW MANY BANANAS IN OUR BANANA PLANT (PLANTATION C)__** 1 hectares = 10 000 m2

Therefore 1 hectare is 100m x 100m

In every 10 m there are 7 bananas and 1 m remaining Therefore in 100m there are 70 bananas and 10 m remaining, therefore 7 more bananas can fit 70 + 7 = 77 bananas in each row There are approximately 33 rows of bananas as 100 divided by 3 = 33.33 Therefore there are 77 x 33 bananas, which = 2566 bananas all together in one hectare In our plantation (Plantation C: located at C8) there are 1.2 hectares. Therefore there are 3,079 in our plantation. **__THE SPREAD OF BBTV IN OUR PLANTATION__**



1 X 2 X 3 X 4 X 5 X 6 X 7 = 7! = 5 040 Therefore 7 cycles of 20 days to spread to our whole plantation 7 x 20 = 140 days to infect our whole plantation **__THE SPREAD OF BBTV ON THE ISLAND__** Total amount of hectares of banana plantations on the island = 2.5 + 9.0 + 12.4 + 1.2 + 35.6 + 48.6 = 109.3 Therefore there are 109.3 hectares of banana plantation on the island 109.3 x 2566 = 280 463 bananas on the island 9! = 362880 Therefore 9 cycles of 20 days to spread to our whole island 9 x 20 = 180 days to infect our whole island’s plantations

__** Stakeholders: **__ All banana plantations need to be informed of the outbreak so that they can check there bananas weekly. We will explain that it has been taken care of and that we are regularly checking bananas at random to make sure we do not have an outbreak.

We will communicate to the banana plantations through all means of medium. This will be throughout walkie talkies, the internet, a written formal letter and a visit to all banana plantations from an ecologist who can identify the disease.

At this stage we believe we do not have to inform our exporters, government or other stake holders as they might be scared off from the banana industry. If there is an outbreak we will inform them immediately, although if our prevention measures are taken serious there should not be an outbreak.

__**SOLUTION 1: **__
===Burn the port plantation plant where the virus has been identified down to be safe. To control the banana bunchy top virus it is recommended that you kill the banana aphids then destroy all infected material. ===

This is our recommendation because plantation plant can produce revenue of $255,060.40 if all bananas on the hectare are sold. This is due to the plant being capable of producing 102.62 tons of bananas on the 2.5 hectares. Bananas are selling at $944 per ton.

On the island there is 109.3 hectares of banana plantation. With the same calculations this means that there is a total of $11,115,120.68 of possible revenue on the island from all the bananas.

This means that the plantation equivalents to roughly 2% of the total banana production. The smart choice would be to burn the infected plantation down immediately to be safe and regularly test the other plantations.

**__SOLUTION 2: CONTROL OF BBTV__**

The most important factors in controlling banana bunchy top virus are killing the aphids and then removing and destroying the infected banana plants. By killing the aphids on the banana plant, dispersal of virus-carrying aphids to nearby, healthy banana plants is avoided. One option in removing and killing the a phids is by spraying them with soapy water, and some insecticidal soaps are legally registered as pesticides. Insecticidal soaps have the advantage of being relatively non-toxic to people, birds, and other animals. The spray solution should be directed to the places where the aphids are most likely to be hiding or feeding. Another method of controlling aphids on banana plants that is often used by commercial-growers of bananas is Prentox Diazinon AG500, which has been approved for use in Hawaii on plants that are not fruiting. Diazinon kills aphids on contact but has no residual effect on aphids. Our recommendation would be using soapy water as it seems more effective and less harmful to other species of plant, animals and people (College of Tropical Agriculture & Human Resources University of Hawaii at Manoa, 1997)

Bananas are selling at $994 per ton. One hectare of bananas costs $102,024.16 and as there are 109.3 hectares altogether
