An oil-in water emulsion with a dithiocarbamate fungicide added and applied to bananas by aircraft controls Sigatoka in Central America and black leaf streak in the Philippines. With black leaf streak, however, large quantities of oil and fungicide must be applied at about double the frequency of application for control of Sigatoka. The level of leaf spot control obtained where black leaf streak is present is not so great as that obtained where Sigatoka only is present. Nevertheless, control levels for black leaf streak meet the minimum standards established for Sigatoka to prevent green fruit ripening in transit due to excessive spotting. These standards, established in Central America, also prevent ripening in transit from black leaf streak in thePhilippines. Similarities in the principles of control for Sigatoka and black leaf streak are further indications of the affinity of the twopathogens. Banana production for the Japanese market is now underway on a large scale near Davao City in Southern Mindanao, Philippines. The black leaf streak form of banana leaf spot is considered to be a more virulent form or race of the Sigatoka pathogen Mycosphaerella musicola by some (5) and a different species of Mycosphaerella by others (2,3). |
