Many diseases cause problems in your garden. Growing a garden is a lot of work and when you pick the fruit or vegetable from your garden, you expect them to be full of fresh garden flavor. When you start seeing a white powdery mildew on your plants, you need to be concerned. All your hard work to produce plants that burst with flavor can be lost with this disease. One of the ways to reduce and eliminate this mildew is by applying a fungicide called OxiDate. Many use this fungicide to dip the plant in during planting and right up until harvest.
