The Philippines, 1960 - Here is the view of a section of the ?adang-kadang" infested area, with the Mt. Mayon volcano in the background. An Experimental Station has been set up in Guinobatan (Albay) to conduct research with a view to eliminating the disease. The Philippine coconut industry is one of the country's most important sources of income. With the assistance of the Food and Agriculture Organization of the United Nations (FAO), the Government is fighting a vigorous battle against ?adang-kadang", a disease that has already killed some 10 million trees.
