Hi All,

Like most moths, Sphinx are attracted by light.  You may find you 
have less problem with tomato beds positioned furthest from your 
night lighting.  Also, I found an excess of nitrogen in the plants ( 
compared to a balance with potassium and phosphorus and calcium) is 
more attractive to all pests.  You might want do do some soil testing 
and consider especially a foliar calcium to improve the cell wall 
structure and balance the nitrogen.  This helps prevent blossom end 
rot also.

I  knocked the old soil out of my pots and used soap and water plus 
sunlight as a sterilant.  Never had a problem.  I suspect some of the 
ultraviolet and ozone technology being used for pre-cut veggies would 
also work, but it's pricey.  Food-grade peroxide should also work. 
All are strong oxidizers.

BTW, I've been invited to speak at the Southern SAWG conference 
January 25-27, hope to see some of you there.
