When your squash leaves look like they’ve been dusted with flour, chances are good that they’ve come down with powdery mildew, one of the most common diseases in the\u00a0vegetable garden. The fungi that cause the disease are somewhat specific to the plants they target. The ones that cause powdery mildew on squash (both\u00a0summer squash varieties\u00a0such as zucchini and\u00a0winter squash types\u00a0like butternut) may also infect\u00a0melons,\u00a0cucumbers, and\u00a0pumpkins. Symptoms range from mild, which may only slightly reduce yields, to severe, killing the entire plant. Here’s how to prevent powdery mildew on your squash plants, plus tips for minimizing damage to infected plants.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Lots of plants, both edible and ornamental, can get powdery mildew. Unlike many other fungal plant diseases, the fungi that cause powdery mildew thrive in\u00a0hot, dry weather\u00a0that’s often the norm in mid- to late summer. As these fungi grow on the surface of leaves, they clog leaf pores and block sunlight that the plant needs to grow. The disease can be introduced to the garden on plants purchased from the nursery, or from spores in the soil. It’s spread by wind, insects, and on tools and hands that touch infected plants.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Powdery mildew is pretty simple to identify. The first thing you will probably notice is blotchy patches of white-gray powdery spots that are dry to the touch on the surface of leaves. These quickly spread out and can cover most of the leaf as well as stems. Leaves turn yellow, then brown and brittle, and finally curl up and fall off. Diseased plants usually produce fewer and smaller fruit. Loss of leaves can expose fruit to\u00a0too much sun, and they may become scorched. If the powdery mildew continues to spread, the entire plant may turn brown and die.<\/p>

Some varieties of squash have leaves that naturally feature white markings. It’s easy to distinguish those natural, healthy markings from powdery mildew by rubbing them with your fingers. If the markings don’t budge, you’re ok. If the white comes off the leaves as a powder on your fingers, your plants have powdery mildew.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
