Currently, many conventional methods for crop management have been insufficient to cope with the effects of climate change on food production such as droughts, heat, soil nutrient deficiency, and the occurrence of new pathogen strains. Utilizing biological inputs, such as Trichoderma spp, has proved useful in improving crop production and food safety. However, in Central American countries there is not enough expertise to accelerate, in a practical way, its use on a broader scale. Here, we report for the first time the study of a collection of Trichoderma spp strains from Nicaragua and Honduras with the purpose of analyzing their genetic diversity and their potential as biological control agents and growth promoters in tomatoes. Genetic diversity was estimated by sequencing the nuclear ribosomal Internal Transcribed Spacer (ITS) region. After.. View more»
