TUCUCH-PEREZ, Marco Antonio et al. Biological activity of plant extracts from Mexican semidesert to management of Fusarium oxysporum from tomato. Ecosistemas y recur. agropecuarios [online]. 2021, vol.8, n.2, e2745. Epub 14-Nov-2022. ISSN 2007-901X. https://doi.org/10.19136/era.a8n2.2745.
Fusarium oxysporum causes losses in tomato production, to control it are used chemical fungicides that affect the environment and cause resistance problems; so alternatives such as plant extracts have been developed. The objective of the present work was to evaluate the biological effectiveness of plant extracts from the mexican semi-desert against F. oxysporum under greenhouse conditions. The treatments were: T1 = A. lechuguilla leaf (250 mg L−1), T2 = C. illinoinensis husk (250 mg L−1), T3 = L. graveolens leaf (500 mg L−1), T4 = L. graveolens stem (125 mg L−1), T5 = chemical witness, T6 = absolute witness (inoculated) and T7 = control; the incidence and severity of the disease, and morphometric variables were evaluated. A decrease in the incidence and severity of the disease was observed with extracts of A. lechuguilla leaf and L. graveolens stem, also a higher development in morphometric parameters of the plants.
