Biological control of soil fungi, pathogens in tree tomato seedbeds

Biological control is a key component in an integrated pest management program by contributing to the decrease in environmental pollution. The general objective of the project is to analyze biological alternatives in pest control in order to reduce the use of toxic pesticides in crops. The specific objectives are: Evaluate the use of antagonistic fungi (Trichoderma Viride and T. Harzianum) in the control of pathogenic fungi (Fusarium sp. And Rhizoctonia sp.) Soil inhabitants. Hypothesis: that the antagonistic fungus Trichoderma Viride controls in greater proportion to the soil fungi than T. Harzianum., And that the biological control of pests is the same as the chemical control in lowering the population of soil fungi. In the control of soil pathogenic fungi, the virid and T. Harzianum Trichoderma fungi will be used in three doses in front of a chemical and an absolute witness. The soil will be inoculated with Fusarium sp., Rhizoctonia sp., Solos and in mixture and in it the tree tomato seeds of the yellow variety will be sown. 3 tests will be carried out at the laboratory level using a BCA design with 9 treatments and 3 repetitions. For the evaluation, the number of plants affected with the pathogenic fungi Fusarium and Rhizoctonia will be analyzed.
