Q.How do I prevent or stop squash rotting?
There was a brief wet period, so I thought that was the problem. Now it’s been dry and the problem is still there. It’s with yellow and Zuccihinni. I have fertilized and used eight dust for bugs. I don’t have a smart phone so I can’t send pics. email is: kayrgrant@bellsouth.net. Thanks for any help.

Many times, once it contracts an infection from a wet period, it will need to be treated. If it doesn't get treated, it can remain in the plant permanently.
There are several options on fungicides. This article will help you to get rid of the issue: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
Alternatively, if this is just affecting the ends of the fruit, and not the plant, then you may be looking at simple deficiencies of calcium and magnesium. This can be corrected with an application of DOLOMITIC LIME.
DOLOMITIC LIME and WETTABLE SULFUR can be used together as an antifungal as well.
