Comparison of the treatment efficacies in the field (ANOVA). The efficacy of strains RGM 678 and RGM 2184 formulated as inverse emulsion (IE) and wettable powder (WP) were evaluated in the field. All the formulation were supplemented with a source of energy. (a,b) Field trials that were carried out in the metropolitan region (Platina) during 2018 and 2019, respectively. (c,d) Field trials that were carried out in the O’Higgins region (Placilla) during 2018 and 2019, respectively. The y axis represents the efficacy (%). The X-axis presents the period of evaluation at 7, 14, and 21 days post first application. The bars represent the means of the treatments, and the whisker represent the estimated errors. The letters on the bars represent a comparison using an LSD test (α = 0.05) of the different treatments evaluated. Different letters in each Figure represent statistically significant differences.
