Evaluación de microorganismos promotores de crecimiento e inductores de resistencia en banano (Musa sp.)
This study evaluated ten treatments, which included six plant growth-promoting and induced resistance microorganisms, one organic amendment, two micorrhycic fungi and two controls, one for each type of substrate used. Their capacity to increase growth in banana plants and resistance to black leaf spot disease was measured. The experiment was conducted in two stages, first in the screenhouse, and later in pots in a field highly affected by the disease. In the first stage, results did not show clear differences in growth variables, except in bocashi and Pseudomonas cepacia, which showed advantages to increase leaf area and plant height. In the second stage, the treatment with bocashi was again the one which had the greatest increases in growth variables. However, Pseudomonas fluorescens and Trichoderma harzianum also achieved good results. P. fluorescens was able to significantly decrease the disease's severity.
