Abstract:
In this study the possibility of using Trichoderma harzianum as a possible promoter of the growth of plants of Pachyphytum oviferum and Crassula falcata and in the biocontrol of Rhizoctonia solani was evaluated. The 2 experimental groups under cultivation were: 1) group without Trichoderma (CTRL), irrigated with water and previously fertilized substrate; 2) group with Trichoderma harzianum (TH) and fertilized substrate. The test showed a significant increase in the agronomic parameters analysed in plants treated with Trichoderma harzianum (TH). In fact, all plants treated with (TH) showed a significant increase in the number of leaves, plant height, vegetative and root weight, new shoots number, stem diameter, flowers and inflorescences number, flowering time. The use of Trichoderma harzianum can significantly influence photosynthesis and chlorophyll content in Pachyphytum oviferum and Crassula falcata and control the development of Rhizoctonia solani. The use of this antagonistic microorganism could therefore be a valid alternative for those growers who, during the cultivation cycle of ornamental and horticultural plants, pay attention to plant quality and respect for the environment, optimizing the use of fertilizers and reducing the application of plant protection products.
