Biocontrol of Powdery Mildews

Biological Control Powdery Mildew

Powdery mildew fungi are obligate parasites of plants that derive nutrients and water from their host, thereby reducing growth and yield through the acquisition of photosynthates. The fungi penetrate into the epidermis directly and establish a parasitic relationship with the plant host through the formation of haustoria, the nutrient-absorbing structures. Mycelial growth and sporulation occur on the surface of leaves and stems, resulting in a white fuzzy mildew appearance. Over the years,...
