Deborah S. Nicdao Significance of the Study in partial fulfillment of the requirements in Science IIB one of the most important fruits in the world;
major dollar earner of the country;
staple food in tropical regions;
despite enormous variety, lack of biodiversity is a huge threat;
replaced the Gros Michel variety on a global scale;
all are genetically identical;
a single fungus can wipe out the whole Cavendish or banana plantations;
caused by a fungus called Fusarium oxysporum f. sp. cubense or FOC;
classified into four pathogenic forms called 'races'; Background of the Study The Philippines is the world's second largest exporter of bananas;
The disease's first attack in the PH was last September 2012;
Panama disease (Fusarium Wilt) is caused by a fungal pathogen Fusarium oxysporum f. sp. cubense (FOC);
wiped out Gros Mischel;
efficiently spread through the plants by the water irrigation system and can spread through floods;
infection of the plants is through the injured roots of the banana plant;
yellowing of lower or outer leaf-blades; Problem Methodology Greenhouse Experiment
1. Banana plants will be planted in healthy soil in each pot.
2. The FOC Race 1 will be placed in each pot and will be waited on until the fungus colonizes the soil of each pot.
3. Different biofumigants and chemicals will be added to the soil in each pot.
1. The growth of FOC mycelium will be observed on petri dishes.
2. Any inhibition zones in the dish will be observed.
3. A solution containing different amounts of the various biofumigant extracts will be applied to each dish.
4. The different parts of the fungus and the proliferation of FOC spores will also be observed under the microscope. Scope and Limitations Scope
bananas that are susceptible to Fusarium wilt (saba, lakatan, latundan)
use of only one banana that is susceptible to the disease;
exposure of the variety to only one FOC Race 1 isolate; Objectives to develop an environmental-friendly way of reducing the population of FOC;
to identify the most effective biofumigants among the biofumigants used; The Philippines is now having problems with how to control the spread of Fusarium wilt in banana plantations. Date and Place of the Study experimentation from the month of April up to August 2013 in the Institute of Plant Breeding (IPB) in UP Los Baños
