Question about daconil

[noinwi]

I recently bought a bottle of ready-to-use Daconil. I know I should have bought it sooner but couldn't. Some of my toms are showing spots on lower leaves that looks like target spot(?). My problem is that the Daconil is so thick it won't come out as a spray even when the nozzle is set on spray, so I'm wasting it because it's squirting right past the leaves through the plant. Can I dilute it slightly so it will spray or will that make it ineffective since it's pre-mixed? Also should I use the diluted bleach spray(as suggested in another thread) on affected leaves and wait a while before using the Daconil? Any advice appreciated.
