Evaluación de tres productos a base de Trichoderma sp. para el control biológico de Fusarium oxysporum en el cultivo de clavel (Dianthus caryopyllus), Patután - Latacunga.

The present investigation was carried out in the Patután neighborhood, Latacunga, located at 00° 53' 9.79" S and 78° 38' 36.35" W, at 2873 meters above sea level. The objective was to evaluate different compounds based on Trichoderma sp. for the biological control of Fusarium oxysporum in the Dianthus caryophyllus crop. Products based on Trichoderma sp. used were Trichotic and Trichoeb powder presentation, in doses of 0.15gL-1; 0.20 g/L-1 and Biosoil liquid presentation in doses of 3 mLL-1 and 5 mLL-1. The solutions were prepared in 20 liters of water plus humic acid (2 gL-1). A 3*2+1 factorial arrangement implemented in a randomized complete block design with three replications was used; functional analysis was evaluated using the 5% Tukey test. The variables to be evaluated were the percentage of mortality, incidence and severity, plant height, button diameter. The results obtained confirmed that the T6 treatment (Trichoeb 0.20 gLL-1) presented the best results, with a mortality rate of 0.27%, an incidence rate of 4%, and a severity rate of 9%; plant height with an average of 55.0 cm and button diameter with 3.23 cm, the results of the microbiological analyzes showed the effectiveness of the applications, where the initial sampling presented a population of 6 x 103 CFUg-1 and in the final sampling treatments T2, T3, T4 and T6 had <30 CFUg-1 soil. Finally, the economic analysis indicated that treatment T6 had a production of 11,048 stems, which represents a net benefit of $1,025.49 with a marginal rate of return of 12%.
