Answer: It sounds like your squash could be suffering from some sort of viral disease. Viruses are spread by insects such as aphids. Once a virus has set in, there is no cure, but before you pull out the plants, call your extension service (702/731-3130) and have them give you a positive ID on the problem. It could be something else. There are no squash varieties that are truly resistant, though some are less succeptible than others. Many weeds are a reservoir of the virus, so aphid and weed control are good tactics to avoid this problem in the future. Also, you can try growing the squash earlier in the season under a polyester row cover (reemay) to exclude the aphids. When the vines blossom, open the covers in the morning to invite the bees to pollinate. A final note - know your pest before spraying an insecticide. It saves you money and time, and is easier on the environment (indluding you!) if you know your foe, and can choose the appropriate weapon.
