Manejo del Moho blanco (Sclerotinia sclerotium), en el cultivo de fréjol (Phaseolus vulgaris L.)

This document deals with the management of White Mold (Sclerotinia sclerotium) in the cultivation of beans (Phaseolus vulgaris L.). The planned objectives were to detail the damage caused by White Mold (Sclerotinia sclerotium) in the bean crop and to establish the different control measures for this disease. The conclusions determine that the optimal temperatures for the development of Sclerotinia sclerotiorum range between 12 and 18°C, conditions that are manifested during the flowering stage of the bean. It is evidenced by the symptoms it causes on the stem at ground level, generating a dark brown or blackish spot that expands to form a ring, constricting the plant and causing its death. Sclerotinia sclerotiorum is characterized by a spongy white mycelium with the presence of small dark sclerotia. Infection promotes extensive mycelium production with the development of sclerotia, which detach and fall to the ground as the tissue is destroyed by fungal activity. In cultural practices, the use of reduced amounts of seed during the sowing process is suggested. Include organic matter (crop residues), implement crop rotation, eliminate crop residues. The application of fungicides containing chlorothalonil, propiconazole, azoxystrobin or pyraclostrobin can serve to improve protective measures against plant infections. In addition, it is possible to use antagonistic microorganisms in the soil, such as the Trichoderma fungus, or use biological fertilizers containing Bacillus subtilis.
