White powdery stuff on my leaves

8 years ago

I planted a peanut plant a few months ago, apart from regularly watering it, I haven't had much time to really look into the plant itself. It's been obstructed by another larger plant which I've only moved yesterday and this is when I saw the white powdery stuff coating the leaves.

I'm pretty sure this isn't how they are normally supposed to be.

It took me 10 mins to figure out where to post this, hopefully this is the correct section.

I see no sign of PM in your images, but every indication of an advanced spider mite infestation.

The speckled stippling and the presence of that very fine webbing are the classic signs.

A plant with a white powdery material on its leaves may have Powdery Mildew, especially if the plants are crowded together and air circulation is limited. A good shower may help or spraying with a mixture of 1 teaspoon of baking soda per quart of water could also. I have also used a 50/50 mix of fat free milk and water with good results.

Thanks. I read a bit about that shortly after posting, I was hoping it would be something else. I did have some other plants where the leaves were turning whitish but that turned out to be spider mites.

I'll try showering it first then maybe those mixtures you suggested. For now I guess it's best to quarantine the plant and keep it away from my other plants.

Could be mealy bugs. Wipe away the 'white stuff' with a q-tip and alchol, it won't hurt the plant. And spray with a general insecticide. The link has some images and more info. Here is a link that might be useful: http://www.denverplants.com/foliage/html/Mealy.htm

White powdery stuff in new bags of mulch
Q

It is a mold that will not harm your plants. Breathing in too much of it when applying the mulch can cause chest congestion which is easily dealt with by taking Mucinex. I had a tree service dump their full truck of wood chips on my drive earlier this year. Some of it had been in the truck for awhile and had that mold in it. The tree service guy warned me about it and told me what to do if it bothered me. I mulched my entire backyard with it because I have giant dogs. One of the names of the mold is "Dog Vomit Fungus". When it dries out it is a powdery grey. A botanist at the University of Illinois told me what it was.

I've done some reading. apparently the peppers are still quite edible as long as I keep washing them off, but it interferes with photosynthesis. so I'm considering taking a bucket of a mild soap solution and wiping every leaf, top and bottom. I figure this will take out a lot of the aphids and whiteflies while I'm at it. the downside is this will probably be a long project, even with only 14 plants. any thoughts on doing this? good or bad idea?

White powdery stuff on leaves of my rose bush

Hi B2, Yes! Roses do very definitely get mildew! I'm linking a thread where I expounded upon my own personal theory on how to minimize the problem, and there will probably be others along with info on what works best for them. When I was in the green industry I used some of the different commercial mildew suppressants, with little improvement, and here at home I had tried the "home remedy" kinds of things like baking soda and milk, but the only thing I've found to work for me is the "watering theory" I talk about in the linked thread. The swap WAS fun! Hope you can make it to the Fall Swap! (Hope I can make it too! I'm taking my vacation a couple weeks earlier than normal this year, and I happened to think, about a week ago, that that might keep me out of the mix this fall! Will just have to wait till then and see what date gets picked!) Good luck with your roses, Skybird Here is a link that might be useful: RMG: Roses

many veg are hard to grow indoors ...

and especially one.. that grows a large root mass for peanuts .. in a small pot ..

you had fun with it.. throw it out.. and try a new devilish experiment ...

its simply not worth spending a lot of money on trying to cure it ... its up to you .. but i figure.. if i have to spend $10 on a cure.. or go find another seed for peanuts... why spend the ten bucks... [see what i did there.. lol]

now.. read up .. and if you find some common cures.. give them a try .. but if you lose ... so what.. live and learn ...

BTW ... part of the problem is .. the mites are sucking the life out of those leaves .. and those leaves themselves.. are never going to 'heal' .... so even even you solve the mite issue... this plant isnt going to be looking any better ..

BTW ... you better be checking ALL your plants.. and put this one in isolation [preferably in the garbage can .. lol]

Yeah, I just tossed it. Got a better look in the daylight, I couldn't tell if the fuzz was from the white stuff or from the plant itself but I did spot two fine spiderwebs. Didn't seem like enough to cover a whole plant, I do remember moving it last week and it was fine otherwise damage like that would not have gone unnoticed.

One more question, do spider mites survive in the soil? This was a mix I made for this plant and I'd like to keep it for the next one.

Not in the soil. Only on the live plant.
