For several years, my zucchini leaves have turned a milky color, wilted, and then died. Is this due to a beetle that spreads a fungus?

You can help prevent infestation of cucumber beetles (the likely culprit) by covering your plants with row covers until they begin flowering. Also, interplanting your squash with radishes has been found to repel the beetles. It would be a good idea to plant the zucchini in a different location this year, and avoid planting in their past location, if possible, for a few years. Keep rotating them in the garden. This will help prevent any disease that overwinters in the soil from infecting your plants.

Hope you have better luck this year!
