I have a home vegetable garden in Fort Worth. This is my first garden. The zucchini are black beauty. They are all the same variety. They are planted in a raised bed with native soil, Scott's premium topsoil, and peatmoss. I have used BT (twice, last was April 29) as well as spinosid (once, on May 30) on occasion for insect control. I water them every other day with a garden hose (on shower) for about 3-min per plant (except once a week they get watered with the sprinkler system for about 25 min). The zucchini have developed some light/dark spots. The zucchini spots are on the leaves, not the fruit. The zucchini has produced one full-size fruit. I think it is cucumber mosaic virus. Is there anything I can do to treat this? Is it okay to eat any fruit that the plant produces while under attack. Thanks!
