之前几个星期长的好好的，还一直结果，收了5个都已经吃了，最近一个星期只开雄花，雌花都不长大也不开花，小果慢慢变黄。现在挂着几个葫芦还是之前授粉的，慢慢长大，其他就不长了。以为是缺肥，最近几天上了blood and bone 和Seasol。还没发现有什么好转。又发现叶子上出现一块块白斑，我上网搜了一下，好像是白粉病，那现在上面挂的葫芦还能吃吗？我接下来该怎么办呢？郁闷

白粉病，有人用酒精擦叶片，有用醋加少许水喷的，不是百分百消除但会有改善。这些方法几天就要做一次，还有要通风不能太密太湿了。

把叶子剪掉？

我也想知道呢，真郁闷，昨天发现一堆青虫卵，今天又发现西葫芦得病了。超打击我种菜的兴趣。

浇水的时候最好不要浇在叶子上, 早上浇水比较好, 老叶子及时摘掉, 就是让菜菜通风不要太湿

Below are 7 home made preparations you can use to treat powdery mildew in your garden.
But first, some general instructions for treating white powdery mildew with anti-fungal preparations: Hose off the plants with a strong spray from the hose prior to treating with these preparations to remove as much mildew from the surface as you can. Be sure to cover all parts of the plant with the treatment spray, including the undersides of the leaves and the stems. Spray some on the soil around the plant as well. Finally, spray for mildew early in the morning before the sun rises too high in the sky. Spray plants once or twice a week in dry weather and more often if rainy.
Apple Cider Vinegar. Mix 3 tablespoons of cider vinegar with one gallon of water. Also works on black spot on roses and aspen trees.
Baking Soda. Mix 1 tablespoon baking soda, 2 1/2 tablespoons vegetable oil and one gallon water. Shake well then add 1/2 teaspoon of Castile soap. Shake the container as you spray your plants to keep the oil and water from separating.
Chives. Use a bunch of freshly cut chives, about as many as you can hold in your closed hand without dropping them. Chop the chives and place in a heat-proof glass container. Cover with boiling water and let sit until cool. Strain.
Corn and Garlic. Take a handful of corn leaves, along with a handful of clematis leaves and as many of the papery outer skins of garlic as you can. Pulverize in blender or food processor. Mix in enough water to make a thin liquid. Let the mixture sit for an hour, then strain. This also works as a preventative against powdery mildew.
Horseradish. Place one cup of chopped roots into a food processor and process until finely chopped. Combine with 2 cups of water in a glass container. Let sit for 24 hours then strain and discard solids. Mix strained liquid with 2 quarts of water. This mixture is also an effective preventative against molds and mildews.
Hydrogen Peroxide. Spray regular hydrogen peroxide (the kind from the drugstore, not the food grade kind) full strength on the affected plants. Do not spray on newly transplanted plants or young seedlings until they become well established. Test on a small area of the plant and wait 24 hours to see if it has any negative reactions to the hydrogen peroxide. This works as both a treatment and a preventative.
Milk. Mix one part of milk with 2 parts of water. Spray every 3 to 4 days at the first sign of mildew. Milk changes the pH of the surface of the plant leaves and prevents mildew from adhering to them. Can also be used as a preventative measure.
