Efecto de Trichoderma, Azotobacter y micorrizas como agentes estimulantes y de control de Rhizoctonia solani en la producción de posturas de cafeto (Coffea arabica L.)
The effect of Trichoderma, Azotobacter and Glomus mosseae on germination of coffee and control of Rhizoctonia solani was studied in Cuba. The following treatments were applied: conidial suspension of Trichoderma, seed pelleting with Azotobacter, Glomus mosseae, Trichoderma plus Azotobacter, Trichoderma plus G. mosseae, and Trichoderma plus Azotobacter and G. mosseae. Application of Trichoderma and Azotobacter stimulated germination of seeds by 37.5 and 36.6 percent, respectively. Utilization of Trichodermafor control of Rhizoctonia solani resulted in a decrease in infection of 36.7 percent. Use of all 3 microorganisms stimulated emergence of cotyledons (80 percent) and resulted in high quality seedlings.
