Banana production in Panama that United Brands would expand its production in Panama because bananas could be produced more cheaply in Costa Rica and Ecuador. The history of banana production in Panama virtually coincides with that of United Brands, which has been in Panama since 1899. The company built railroads, port facilities, and storage areas for the processing and export of bananas. In the 1930s, a disease seriously curtailed banana production. In the 1950s disease resistant plants were developed, and production increased rapidly. In the early 1970s, a "banana war" erupted when banana-producing countries disagreed among themselves and with United Brands about an export
Panama disease upwards of 30 years. When the environment is ideal and there are host roots available, these chlamydospores will germinate and hyphae will penetrate the roots, initiating infection. There is in increase in the number of symptomatic plants when inflorescences emerge and the highest disease incidence occurs right before harvest. Once infected, microconidia are produced and present within the vessels of the plant’s vascular system. Macroconidia are another asexual spore that tends to be found on the surface of plants killed by Panama disease. Infection is systemic, moving through the vascular system and causing yellowing and buckling that starts in older
