Blight... or something alse?
I feel like crying just a little bit.
I have dedicated every free minute of my time growing few hundreds varieties each year for 6 years now, never had any major troubles... until day. I walked to my greenhouse after three days (yeah, a protected greenhouse) this evening and saw this. Every single plant has been infected - some more, some less. But it's spreading quickly. I would really appreciate if someone alse can suggest which disease this might be, before I spray it in the morning. So I make sure I take the right treatment. GREENHOUSE I also spoted this on my balcony - I suppose that would be a bacterial infection. I treated plants with sodium and it helped a little, but I saw today it's still there - at the edge of leafes. I suppose I will treat them with sodium again. BALCONY Once again - every answer will be greatly appreciated! |

I am guessing it is powdery mildew. Is it humid in the greenhouse?

Hi AlittleSalt. Checking photos on Google it doesn't remind me much of powdery mildew.
But I can see what made you think that - the light spots on leafes are from previous spraying (that seemed to help, right?). It was obvious to me, so I didn't write it down, sorry. What troubles me is everything alse and it seems like an early blight. It's not very humid - I have that same greenhouse for 5 years and never had trouble. |

I don't know what it is but it does not look like early blight to me

It is grey mold. Get it with liquid copper fungicide, mix at the weaker dose on the labels recommended range. Don't get it on the blossoms. Be thorough, over and underside and stem down to the soil line too. Then repeat every 7-10 days as a preventive. Sodium really won't help this.

I think Marsha nailed it. Also use the copper spray on your balcony plants. That looks to me like Bacterial Spot.
It is not Early Blight. |

Yep, that's Gray Mold ((Botrytis cinerea)

Wow guys, thank you so much!
I was planning to use copper, but knowing what it is makes me feel just a little bit better. I'm going out to spray. Thanks! |

Good call.
Also, some sprayer heads/nozzles, have a fine line between a good coverage and along with that is a very fine mist that travels with the slightest breeze. A loose piece of foil works well to cover any precious blossoms, (and easy to remove). |

I hadn't heard about avoiding the blossoms before. What is the reasoning behind that?

The copper will certainly slow the disease but I would use the diluted bleach spray and not just hit the plants but everything in the greenhouse to kill all the spores that must be everywhere in there. After using the diluted bleach spray I would come back the next day and apply a copper spray for prevention. I don't know what quality of bleach is available in your country so it may be difficult to find something suitable but read the thread below and see what you think. I fight gray mold every single year because I love to grow black tomatoes and they are highly susceptible to it and it can spread fast here where our climate is so so humid. Good luck.
