What's happening to these pants?
Can anyone help to identify this malady on my tomato leaves? I had found thrips a few days ago and immediately sprayed with pyrethrin & canola oil (Take Down garden spray). But I think this may be unrelated. Any thoughts? Recommendations? Thanks!

Definitely fungal, kinda looks like Botrytis Gray Mold, not sure.
I hate moldy pants. |

Could a foliar spray of Daconil or Actinovate fix things?

Not if it is Gray Mold. It could also be some Early Blight. Cut off the affected leaves and spray with Daconil and see if that helps. If it is Early Blight then it will usually be kept to a minimum with the Daconil if used every week. If it is Gray Mold it will return rather quickly in my experience especially if you get a bit of rain.

Are you preventatively spraying Daconil or an alternating regimen of Actinovate and Exel LG? The fourth picture could be mold/botrytis as others described above, and I know no treatment for that.

If it is Gray Mold, Botrytis thrives in wet, humid conditions, what's the weather been like?
I don't see any concentric rings in the infected areas that would be the sign of Early Blight. This is Early Blight: |

No, I wasn't preventively spraying. (I should have been, I know). I guess I'll order some Exel LG. Would it be recommended to alternate Actinovate, Daconil, and Exel LG in a three-part rotation? Or can two of these three be mixed together? How often should I spray? I don't have much experience with preventative spraying. Thanks. |

Daconil should not be mixed with anything.

Mix Actinovate with Exel - no issues.
I don't use Daconil but rather alternate weeks with Actionvate/Exel and Serenade. Either way start your preventative routine and stick to it, factoring in rain of course. |

Daconil - chemical
Exel LG & Actinovate - organic I've used Daconil. I have not used Exel LG & Actinovate, but next in-ground garden, I will. Actually, for my 4 container plants, I am using Happy Frog 5-8-4 fertilizer which has a wagonload of ingredients including 15 types of Mycorrhizae and 5 types of beneficial bacteria. Looking forward to the results.

That last one is definitely thrip damage. I'm fighting the little buggers myself right now. I know when I see the white patches with black stippling that thrips are at work. They are attacking some very small seedlings of mine right now, and I'm not sure if spraying seedlings that small will kill them, so I'm just watching and waiting. I hate thrips!
