Efecto de la inoculación de Trichoderma spp. en la sanidad del rizoma y suelo en el cultivo de banano (Mussa AAA)

Abstract

The objective of this research work was to demonstrate the Effect of inoculation of Trichoderma spp. on the health of the rhizome and soil in the cultivation of banana (Musa AAA), in order to implement biological alternatives to try to reduce the impact, environmental and human health, where Trichoderma spp., was used, in soil and roots; applying only once up to 90 days of experimentation. The application of the fungus was carried out against the selected productive offspring of the banana mother plant, in its three doses or treatments (1, 2 and 3 l/ha) plus the control, with four replicates of each treatment obtaining 16 experimental units. Data collection was carried out by measuring (heights m and diameters cm) the return, at a frequency of 15 days to 75 days, demonstrating the benefit of using 2 and 3 l/ha of Trichoderma spp., but not 1 l/ha. Meanwhile, Trichoderma spp., controlled M. incognita, initially presenting the lowest values of nematode populations up to 90 days after applying, but not in the nematodes (H. multicinctus, R. similis and P. penetrans). The application of Trichoderma spp., in soil at doses (1, 2 and 3 l/ha) did not present control effects on the populations and types of nematodes, it is recommended not to use Trichoderma spp., since in the soil they serve as food for existing nematodes, multiplying their populations at higher doses, the greater their nematode populations will be.
