 I have some jack-o-lantern and gourd seedlings in my garden that have
 developed rumpled leaves.  The conditions for Mosaic virus do not exist
 here.  It has been very dry.  could that be caused by a sudden change
 from cool to hot temps like we have had here in UT?

It could be the damage listed below, but is difficult to tell by Email.  Hope 
it's not.

I've mentioned this in years past but thought it was important enough to 
repeat.

Make sure you know what your neighbor or landscape company is using for weed 
killers in your neighborhood.  Don't find out the hard way like I did a few 
years ago.  Some weed killers used on woody plants are volatile and can 
vaporize when temperatures reach 80 and above.  The most common culprit is a 
2-4-D ingredient in it's volatile formulation.  If there is a light breeze it 
can then drift damaging or killing plants 100's of yards away.  Most 
susceptible are Pumpkins, Squash, Cukes, Tomatoes and Peppers.  The damage 
looks much like Mosaic Virus and is often mistaken for this.  One report 
showed damage to a vineyard one mile from a road crew using a strong volatile 
Herbicide along side a highway.  In most cases this is not a problem and the 
Herbicides are used responsibly.
