Control of white mold in bean plants by homeopathic medicines

Abstract

Common bean (Phaseolus vulgaris) is one of the main Brazilian agricultural crop. It is affected by numerous diseases during its life cycle; one of these includes the white mold caused by the fungus Sclerotinia sclerotiorum. The objective of this study was to verify the control of white mold in bean plants by homeopathic medicines. Two tests were performed: In the first test, the medicine Calcarea carbonica was used, while phosphorus was used in the second test. Both medicines were administered at dynamizations of 6, 12, 24, 36, and 48 CH (Hahnemanniana Centesimal). In the control treatment, 30% hydroalcoholic solution was used. The study was conducted using a completely randomized design, analyzing the following variables: Area under the disease progress curve and percentage of dead plants. The results were submitted to Tukey's test and regression analysis (p > 0.05). Calcarea carbonica at 6 CH and Phosphorus at 6 CH, 12 CH, 24 CH, 36 CH, and 48 CH reduced the intensity of white mold in bean plants. With the exception of Calcarea carbonica at 12 CH and 24 CH, no other medicine reduced the percentage of plant death due to white mold disease.

Efectividad de Biofungicidas para el control de la roya en plántulas de café

“…Leonel y Barros (2013) obtuvieron menor incidencia de H. vastatrix usando complejo homeopático, observando mayor vigor vegetativo. Asimismo, Rissato et al (2016) obtuvieron la menor incidencia del moho blanco del frijol (Sclerotinia sclerotiorum) con aplicaciones de medicamentos homeopáticos. Por su parte, El-Sharkawy et al (2015) utilizaron Streptomyces viridosporus en combinación con Trichoderma harzianum para el control de la roya del trigo en invernadero (Puccinia triticina), con la que obtuvieron una disminución en el número de pústulas por unidad de superficie (cm 2 ).…”

Recent Approaches towards Control of Fungal Diseases in Plants: An Updated Review

“…Consequently, plants can resist pathogens and diseases with their own means [124][125][126]. The homeopathic medicines phosphorus and Calcarea carbonica were used to control white mold in bean plants [127].…”

Homeopatia no manejo de ferrugem em Coffea canephora cv Conilon

“…No manejo de doenças, a homeopatia foi eficiente em reduzir a incidência de ferrugem do café (LEONEL; BARROS, 2013) e de mofo branco (Sclerotinia sclerotiorum) no feijão (Phaseolus vulgaris) (RISSATO et al, 2016). Ainda, em pesquisa com café arábica, o uso de preparados homeopáticos foi capaz de reduzir a severidade de ferrugem na planta, a queda de folhas e ainda favoreceu o desenvolvimento de novas folhas, comprovando que seu uso promove resistência a planta de café (RODRÍGUEZ-HERNÁNDEZ et al, 2020).…”
