Hi all,
I recently noticed a tiny bit of powdery mildew on some AVS. I removed them from wicking and matting and increased air circulation even more.It seems to me that someone here mentioned Lysol in the plant area for that problem.
Can someone refresh my memory? I have never had that happen on handwatered plants.

Lysol
I had powdery mildew on a couple of plants once. I put them on the toilet and sprayed in the air and let it fall down to the av's. Worked great. I have never had that again, but the Lysol worked. Make it a very light spray and wait and make sure all it well. Just be careful since each plant is different. Good luck.
Thanks,Sally,I will try it!! I will be careful.I assume you are talking about the regular Lysol santitizing stuff in the blue and white can?
Yes, regular and I sprayed above, lightly.
any of the scented ones will work too,i got some in a purple can for when i have problem,(which hasnt happened this year yet
Also, let them dry off. Don't put them in light right afterwards. How many have a problem? I only had two or three. I have not had a problem since then, about a year ago.
It's only 4 or 5.The rest are fine.I moved them to a different location anyway,because I always do that if any plant has a problem.
When I foliar feed, I have Physan 20 added to the water . . . that is good to use against powdery mildew.
Thanks Syru,
So far I have not been using anything for pests and disease.I inspect my plants very carefully everytime I water though.
You will be fine. I bet the Lysol will work great for ya. I do not use chemicals in the soil, etc, so far so good. I cannot be around chemicals and I have a bird too.
The places I buy my AV's from use them of course. They have to with large amounts of plants. I am glad. But I do not add any.
I am not fond of chemicals.I only use them when I have to.
Can't wait to see how it all worked for you.
I'm not particularly fond of chemicals either, but since it gets so hot here, powdery mildew is a constant problem. Since I started adding a bit of Physan20 to the water, I have not had a problem. Plants even seem greener, but that could be the new fertilizer . . . ^_^
(the "hard core" chemicals I have are Marathon and AVID - they are high up in a kitchen cabinet - and will only be used if needed)
Sally, you never told us what happened to the violets that had yellow on the ends of the leaves? Did you end up changing water or not? Give us your solution, please.
Well, they are fine. The AJ yellow submarine is really green now, this is an older pic... I took off the more yellow leaves. They were healthy, but yellowing.
My other plant is doing fine, a bit more green. I use fish fert. and it seems good for them. I repotted also. I think with more time, the other will be fine too.
I just wondered if you changed their water as I changed mine to 1/2 RO water and 1/2 tap. The plants are loving the change.......
No, I still buy spring water.
I still use plain old tap water,letting it sit for a while before watering (the day before if I am able),but sometimes I have to draw it straight from the faucet.The water here is hard and has lots of lime,so I tend to use a little more acid mixture for many plants and do not add lime to my potting mixtures.
Syru,
I know I should probably use Marathon and/or Avid,but if I really run into a problem I can still buy Kelthane,Malathion, or Diazinon cheap,plus using things like Clorox,Lysol and hot water baths is practically free!! I just try to avoid ANY harsh chemicals anymore....unlike when I was younger LOL.I was so paranoid when I first started growing that if one leaf or plant looked at all funny,such as one tight center,I would dip or submerge all 300 or so,let them drip dry,then spend HOURS hand drying them with soft cloths,tiny little paint brushes,and even blowing on them...I have learned a lot since then!! I did spray the 4 plants with powdery mildew with Lysol.I will let everyone know how that goes.
Lynn ^_^
My water tested at 7.8 so I made the change to half and half. Of course RO has no minerals at all so I can't use just RO water.
I think I told Heidi it was over 9 but I got my numbers mixed up and my brother corrected me on the ph of my water.
Lynn - I haven't even opened the AVID. I won't until I see a reason for it. The Marathon I have used, but it was used on the plants that I took to the club show/sale in May. I haven't had a reason to use it on my own plants before. For the club sale, it was mainly for preventive maintenance.
Well, I'm almost happy with my AV club again! I finally got my proceeds from the sale in May, so can go and get a few more perma nest trays on Friday, and still have enough to renew my AVSA membership! WooHoo!
We discussed more on the state show in November. . . there will be 2 dinner choices for the banquet - NY strip and Chicken Diane (or something like that!). A vegetarian dish will be available for those who want it.
Since rooted leaves were not encouraged for the club sale, I didn't think that was something that would be good for a state sale. They said tonite that those would be a great thing to have at the club table, so I am going to stick alot of leaves this weekend, just for sale purposes.
I even spoke up and suggested a 'lesson' for next month . . . I would very dearly like a lesson on trailers - grooming, trimming, etc. I've got some semi-mini's that are starting to bloom, and I think they look good . . . even for November!

sorry the lighting is bad . . . ^_^
p.s. - sorry, too . . I forgot this was the Lysol thread, not the pix thread!

I have successfully used a spray bottle of water with a Tbsp of baking soda mixed in for powdery mildew. Works great if you want to not use chemicals.
You have the cds on grooming, etc..........Nichole........
plus what Judges Look For........I bet you forgot about them. Marjorie made me copies for me.
Oh, I haven't forgotten, and I have watched both.
Thanks for the new idea jmp24!! I have used lots of concoctions outdoors,but I'm never sure what is safe for Gessies.
Syru,
I just read an article somewhere about grooming trailers.It was talking about one plant to a pot,pinching,etc. If I can remember where I will post it or Dmail it to you.
Lynn
Thanks, Lynn. ^_^
Somewhere around here, I still have something Marjorie gave to me a couple of years ago. It was several papers stapled together with each entry in a show and how they should look and what the judges would be judging on. I will start look, Nichole.
Lynn, I would also love to see that article on trailers too...if you don't mind. I have a few new trailers and don't want to get off on a bad start with them.
Also, my mom just told me that she saw on one of those tv gardening shows that mixing milk and water and spraying on mildewy plants works too. I will have to look into it and see if I can find more info.
I am finding articles by Critter on trailers here on DG:

http://davesgarden.com/guides/articles/view/2158/
Here is one more I found......not from DG though.
http://72.41.11.187/trailfs.pdf
Thanks so very much for the info Gail. I really want to try some semi-trailers!! This is the exact info that one needs.!!
Lynn, if you have any more articles, please post! I learned something new. I always thought that you could only have one plant with three side crowns. This last article says that you can have as many plants as you wish for competition as long as each plant has at least 3 crowns.
Hey all!
I have not been able to read the threads for a few days. Could someone back up and explain the hot water bath for plants and what it is used for? Hot water won't hurt the plants? And the clorox thing. Sounds interesting.
Thanks!
Connie
Lynn, I mean to mention that the baking soda and water mix I have NOT used on AV's....I don't imagine it would hurt them, but I'd do a little reasearch before trying it. It works great on other plants.
I just took the dogs out and was inspecting my outside hoyas and it seems the citrus aphids have landed.....I need to take care of them right away, they are easy enough to get rid of, but if you let them stay too long on new growth, the new leaves will be all pitted and deformed from their chewing.
"citrus" aphids?
yeah, the bright yellow ones that showed up in my area about 10 yrs ago, supposedly they were only in California before that, but have now spread all over the country due to being shipped on plants.
Aphids don't scare me, it's scale that i really worry about, and spider mites, but I don't really grow anything prone to getting the spider mites.
I just sprayed the hoya with a little Safer's Insecticidal soap. Works great, but they'll be back! You just have to stay on top of them, not let them get the upper hand.
I can't post the article I read,because it is in an AVSA magazine,so I'm pretty sure it would be copyrighted.It gives much of the same info on the links Gail gave,but goes a little further.
One use for Clorox is to drench plants with 1/4 tsp Clorox to 1 quart water to control Springtails and other soil and saucer insects.
As for the hot water treatments.....cyclamen mites are very sensitive to heat.The plant is imerged in usually 110 degree water for a specific time.The problem is not everyone agrees on how long to keep the plant submerged.I have used the hot water method with success.However one formula I followed damaged a lot of plants.I would reccomend using one put out by an AVSA society.
Lynn
This is a good article.

Laughing as i type this!! I will keep my Avid, Conserve and Admire Pro on hands at all times for pests.
These chemicals are nothing compared to what they use in farming and comes out of a duster plane................I don't have cancer yet (smiling) and I grew up with all these chemicals much stronger than the ones used for gessies.........
Yes, Gail...those are strong chemicals and you KNOW when one has flown over!
Remember I am not young now.......but when I was a child growing up we didn't even know to be afraid of DDT (which is now outlawed). We would go outside to watch the dusters spraying the crops and our mom didn't even tell us to stay in the house.
****edited to say Thank You, Lynn, for that good article from A&M
