Abstract
Squash (Cucurbita pepo L.), is one of the most important vegetable crops for
human nutrition not only in Egypt, but also all over the world. Powdery mildew is the most serious disease that attacks squash plants and causing yield losses. Plant diseases are controlled by recommended chemical fungicides that are not environmentally acceptable because of their hazardous effects on human, animals, plants, and other organisms, as well as, the development of fungicide - resistant pathogen strains. However, alternative strategies like resistant cultivars and biocontrol agents should be used instead of using synthetic fungicides for controlling plant diseases.
