In the case of the kidney tomato, the quality of the product has been affected due to several diseases, but the main one that occurs most frequently is known as late blight (Phytophthora infestans) and in order to try to solve this problem, a the use of plant extracts, thus trying to replace the use of synthetic fungicides and in turn reduce environmental pollution and the negative impact that these have on the environment. This research work aims to evaluate the antibacterial and antifungal activity of plant extracts from plants such as Molle (Schinus molle L) and Marco (Ambrosia arborescens Miller) against a phytopathogen Phytophthora infestans responsible for causing late blight in the kidney tomato fruit. In which, as a first step, the plant species were collected in the Zuleta commune, Ibarra canton, Imbabura province, the two plant species went through a dehydration process in order to obtain a total extract through a process called dynamic maceration and to This was done using a solvent called methanol at various serial concentrations that are 500, 250,125 and 62.5 mg/ml with the help of the Kirby-Bauer methodology, performing direct diffusion in agar on the previously isolated phytopathogenic agent Phytophthora infestans. Currently, plant extracts have been evaluated for several crops, among these studies is the kidney tomato crop. The great diversity of plants that our biodiversity offers us is a source of bioactive compounds for obtaining potential natural extracts that strengthen the organic control of diseases in tree tomato cultivation. |
