powdery spots or large blotches on the surface of leaves, stems and fruits of host plants. The white powdery growth consists of the fungal mycelium and asexual reproductive spores.

POWDERY MILDEWS Powdery mildews occur throughout the temperate zones worldwide and, next to rusts, are probably the most common, widespread and recognizable diseases of food and ornamental plants. The total loss of crop yield and plant growth on all crops more than likely surpass losses caused by any other single plant disease.

to Powdery Mildew Powdery mildews are most likely to develop in the spring or fall when: • Temperatures are between 62° - 72°F • Relative humidity levels are 70 percent or greater • There is reduced light intensity Moisture on plants from dew or irrigation does not favor the development of powdery mildew and can even limit the disease. Unlike most fungi, powdery mildew spores do not require free water for germination. Spore germination is enhanced under elevated relative humidity. This adaptation renders management of powdery mildews especially challenging in glasshouses and irrigated fields where relative humidities within canopies can be high enough to promote infection.

Abstract. Grape cultivation throughout the world is affected by various disease problems among which three fungal diseases viz. powdery mildew, downy mildew and anthracnose pose serious constraints in getting desired yields of good by: 6. Most powdery mildews are recognized by white to gray powdery spots or large blotches on the surface of leaves, stems and fruits of host plant. The white powdery growth consists of the fungal mycelium and asexual reproductive spores.
