A Gardeners Forum Forums General Discussion Plant pests and problems white circular spots and browning leaves that fall off

I have a Jade Snap Bean Bush and a Bush Crop F1 cucumber plant that I am growing in containers indoors. The green bean appears to be almost dead, and the cucumber appears to be following. The plants are getting white circular spots and browning leaves that fall off. The few green beans that developed also have the same issue. Any idea what is happening? :-)

I say you got the blight..Indoors??
Strange why are you indoors in summer? Beanc an cuke indoors??

I too am curious why you are growing indoors as opposed to outside?? It looks like these plants have been developing these fungus for a while, to be in the condition they are in.

Dodge and Angelblossom:

Thank you for your responses.

This is the first time I've ever tried to grow anything - I just sort of had an impulse this year and gave it a try. I live in a city in a third floor apartment. Essentially there is no "outside." I do put the plants out on the fire escape where they get about 4 hrs of natural light, before bringing them in and using grow lights. Perhaps being out side is where they were exposed. It has rained pretty much all summer (for a month straight at one point) and I read that that contributes to the blight. Having identified the issue I've been reading up about it, and apparently this year blight has been a big issue. The cucumber has developed the blight/powdery mildew over the last two weeks. The green bean plant has been dying for the last month. Other gardening forms believe the green bean plant has mites.

From what I have read so far, it looks like a Chlorothalonil fungacide for the powdery mildew and for the mites maybe a Rotenone insecticide. The plants are probably too far gone for organic solutions. Any other suggestions? I'm not sure they will survive long enough for me to get anything though.

I also have a strawberry plant that is doing well and producing, and a blueberry plant that is doing well but is still two years away from producing, and a tomato plant that is extremely robust, but hasn't produced a single tomato.

Tomato needs sunlight badly to bear. I think it says 8 hours. Most veggies need sun also.
Read labels when you buy.

Don't know your location. zone

I don't know about blight, etc... and don't grow vegetables anymore (except one volunteer tomato plant I have right outside my front door). And, I don't know about chemicals. I do know that if it were me I'd be picking those bad leaves, etc off and discarding them...get them off the plant and out in the trash. To leave them on the plant will just further whatever is going on.
