Abstract
The most serious disease of abaca in the Davao and Cotabato Provinces of the Philippines is stated to be the one previously reported as vascular disease or wilt. A survey in Davao (covering only about one-fourth of the total abaca-growing area) during May, 1937, to December, 1938, showed a total of 1, 301.5 hect. affected by the disease; of these, 1, 059 hect. have now been eradicated and partly replanted with the resistant Tangongon variety.
