Tomatoes for 2016

Have a nice sized Pruden’s Purple in the ground already. I’m hoping to get enough of a head start this year to get multiple tomatoes off this guy, and hopefully use it to sire some intended crosses. In the past I’ve haven’t given this one as favored of a growing position because it doesn’t set a lot of fruit and has exhibited a lot of vegetative vigor. I’m trying to go the other way this year, and put it in one of the best spots I have left to see if more sun and a head start gets it fruiting more heavily. I’m considering training it kind of like a center leader tree to encourage fruiting on the side branches.

Reading online states its ok to mix mancozeb together with copper when spraying.
Edit:
Just read bonide mancozeb label.
Saying you can mix combination of half rate of mancozeb with full rate of fixed copper.
