Evaluation of SINMAX for the Control of Black Leaf Streak (Mycophaerella fijiensis) in Banana (Musa sp.)

Abstract

Black leaf streak (Micosphaerella fijensis) is one of the main causes for reduction in banana production. The search for natural alternatives for control of this fungus has become important because of the growing demand for products that are more environmentally friendly. It is important to develop a strategy that is both innovative and reduces the dependence on conventional chemical controls. The objectives of this study were to evaluate the effectiveness of two forms of SINMAX (SINMAX A and SINMAX B) for the control of black leaf streak and after the application, to evaluate the nutritional content and vigor of the banana plant. Regarding the effectiveness in the disease control, all the treatments showed positive results. The number of leaves on the plant did show significant differences (p<0.05) in the T4, SINMAX with agricultural oil, as compared to the other treatments. Plants treated with T4 also had a greater leaf area, but the difference was not significant (p<0.05). The chlorophyll index and diameter of the pseudostem were greater with the T#, the treatment with the highest concentration of SINMAX.

Key words: banana, Micosphaerella fijiensis, black leaf streak, SINMAX.
