My New Girl tomato (supposed to be improved on Early Girl) is productive but has curly leaves---not present on neighboring plants. What disease could this be? Seems like the tomatoes are slow in ripening this year. What could cause this?

Tomato leaves will curl due to several factors. For example, some varieties are more prone to leaf curl in hot weather than others. The following publication may offer some suggestions:
Tomato plants are also very sensitive to herbicidal burn. 2,4-D and glyphosate (Roundup) will volatilize in hot weather and will drift with the slightest breeze for a great distance. Typically, the top leaves of tomatoes will become distorted and twisted when hit by one of these chemicals. The plant usually grows out of this damage.
Tomatoes and some other plants are two or three weeks behind their normal schedule this year. This was due to the late spring and the delay in the soil temperature warming up.
