Possible red blotch on my bulbs

14 years ago

Ok I donÂt think I posted here before IÂve only lurked and learned now I am fearful that I have a bad case of Stagonospora curtisii (red blotch). I am praying it is a bad case of sun burn, but am realistic. Now to the hard part: if it is red blotch is there anything I can do to salvage these bulbs or are they to far gone.

VERDICT: Stagnospora curtisii

#1 killer of Hippieastrums.

Treatable but a long process that is why experts recommend to just throw/dispose of bulbs.

TREATMENT:
Peel as much as you can of the bulb's scales until there are no more red spots.

CLEAN that neck! Peel all brown dead tissue and cut out soft/mushy parts as much as you can.

SPRAY the whole plant, bulbs neck, leaves (top and bottom), scapes with copper or manganese based fungicide. This will have to be done every 2 weeks until it is controlled. SYSTEMIC fungicide will NOT kill STAG. Some say that it "could" prevent it but I have doubts about this. It is always best to have HEALTHY Hippies that can fight back if it gets STAG.

Paint cuts/wounds with Captan.

ONLY bottom water or avoid having whole plant getting wet.

This will usually take care of the Stag IF it has not entered the inner scales yet. If it did, dispose of bulb, do bulb surgery, or just chop it up and do cuttage propagation.

You will ALWAYS have t have a constant look-out for possible further or new development of Stag in ur hippies.

Been there. Done this. Took me almost 4 months to control the Stag that hit the collection 2 seasons ago.

LESSON LEARNED: ONLY buy from reputable bulb comapanies if possible. Once you receive your bulbs, CHECK them and PEEL those dry scales. Any sign of red is trouble or possible trouble for me. SEPERATE newly puchased bulbs from your other healthy bulbs. STAG is very contagious that can be transfered from one plant to another through water splash, rain or simply through your own hands.

Hope that helps! Good luck!!!

Well this is what I still don't get: we are advised to take them outside to get sun and grow healthy leaves, but they are not supposed to get wet to avoid the stag. But it does rain, and sometimes it pours - what's a person to do? Only bottom water when they are outside? How? Sigh...

Report on use of Neem for Red blotch

I never sprayed Neem on the leaves. I removed leaves that were badly infected with red blotch. All i sprayed last year (outside-- i would never use this inside) after flowering was the bulb top and soil, my aim being to nurse it along until it was time to give them a rest-- then i cut off the leaves and sprayed well. Hans has writen that the mites will never really be gone without the hot water treatment-- but i hope to keep them under control with this. I expect the 07 flowers may be fewer, due to me removing leaves in 05, but at least the bulb survived. This year her fiancee brought me a HUGE bulb, that i sprayed before i planted it -- it of course was also infected. (Hans has said every bulb from the Netherlands will be.) It is not as clean as these two are-- but better off than if i had done nothing. Now and then i just peel off small areas of bulb skin. Of course i never know the names of these varieties bought in flower markets. But now that i believe i can control the problem, i will add some named varieties to my collection. Thanks again to everyone-- i have learned much here. mary

AuntJemima, That's really really sad to see what you're dealing with with those poor bulbs, especially since they had such nice roots to being with. Five or six years ago I made my first cross and knowing nothing about amaryllis I grew the seedling to about the size of a grape (I was so proud of myself!!) and planted them in styrofoam coffee cups with just one drainage hole. Then I watered the daylights out of them for the summer. Result: All came down with red blotch. I threw most of them away but I saved about 3 of them and dunked them in a 3% bleach solution. This burned the leaves and roots and the outside of the bulb. I then took them and put them in plastic coffee cups this time and just forgot about them..Didn't water them and several months later they started sending up leaves, To make this long story a bit shorter, I was able to bring one to flower. So if you're still experimenting and you've got a couple of whole bulbs it wouldn't hurt to give it a try, all they can do die which they might anyway... I wish you luck, it's not pleasant to play nursemaid to so many sick bulbs... Donna

Red Blotch & seedlings/offsets
Q
Comments (3)
Seedlings should not be infected. Some types of fungi can pass from mother to seed because of mycelium residing in the seed coat or embryo, but in my experience this appears not happen with red blotch. Seedlings will grow up without the fungus, if they are not secondarily infected after germinating. The offset could be infected because of its close contact with the mother. It would be very easy for spores of the fungus to be transferred from the mother to offset. But my understanding is that red blotch is not systemic, so it is not passed directly through though the living connection. This is unlike mosaic virus, in which the offset is nearly certain to receive the disease directly from the mother plant. In Hippeastrum, many types of leaf damage can result in red markings, so yours may not be red blotch. If it is, however, it does not appear to be a serious case. I think most of us have red blotch in our collections, but we learn to manage it. I would be curious to hear if anyone here believes that s/he has a blotch-free collection. Maybe I am overly complacent about this. But in any case, it would do you well to try to prevent it from entering in the first place... Bill

Stagonospoa Curtsii (red blotch) help

Do you have a link to these "natural antagonist"? The red blotch seems always with Amaryllis. After one year, research, shopping Amaryllis online and local. I can see red blotch in all products sold. Most are minor infected, but it is obvious to the eye from my experience. I derived a process below, so it is under control and none observed so far on my 1st bulb started 5 weeks ago. It is in full bloom now, started at the south warm window and moved to the cooler north side of the house to slow the flowering process. I am starting a 2nd one today using the same process. The attached photo was the new bulb I bought this year from local. The seven I bought last year are still in the dominant state. 1. Keep the bulb dry at all time, 2. Bottom-up watering, 3. On new bulb, I start it soaking in bleach mix with hot water at 120F water bath for a few hours, 3. Then dry it out with a small fan on it for a couple days while the bulb starting on the water with base plate slightly above the water line. 4. Transplant bulb to a pot after a few days with loose soil (cactus type mix) with bottom of the pot touching a pan of water, 5. The bulb will look bone dry with green flower spike coming up, 6. After the flower above to start out, put the pot in a tall glass cylinder to help support the height of the plant with foam or cardboard cut out at the top of the glass cylinder. I bought seven this year below (6), first one was from Home Depot at $7 each but smaller than these at the high-end local nursery at $17 each. These are big over a pound in weight, one tip the scale at 23 oz. So I have 14 total in my collection and curious how last year bulb turns out.

Hi Anna!

I wrote "Only bottom water" for the sick treated bulbs. Just so that the wounds would heal good and that the STAG do not develop/spread further.

I just hosed down my hippies today as we have had no rain for 3 days now. And the hippies LOVE these on hot weather and keeps the mites away too. LOL!!!

The thing is to keep a watchful eye. Once I see a red spot or two, I seperate them, far away from the rest and treat them ASAP before it spreads. I usually bring them inside my garage. It's my ICU. It is best to catch it at the earliest stage if ever as treatment is easier. If you don't see any signs, then they are fine.

After growing hippies for so many years now, I have developed this beliefs. I will try to give them the best growing conditions I can give them that I can afford. I can ONLY do so much. Nature will have it's way no matter what. If a Hippie gets sick or dies, it did not die in vain as it has taught me a lesson well learned. (Remember these words Frank?)

Hippies are very strong plants. If their leaves get sick, they have "life" stored in their bulbs. Their bulbs are developed as a "defense system"...layer upon layer of scales protecting it's heart (core). If both leaves and bulb get sick, it still holds it's lifeline...the basal plate and roots.

Don't worry too much Anna. Unless you're going through PMS like I am. Then I totally understand how you feel. LOL!!!

Ahhhhh...fall is just around the corner. I can't wait till the Hippies are put to rest. I AM tired and would love to have some rest too!

Happy gardening to all! And hope 2009 season will be a Stag free one. Yeah right! This is almost impossible with all these stag infested bulbs they are selling us.

Hi ajsblu eyes!

You are most welcome!

Head's up! Don't give up hope and try to save your bulbs. They are relying on you. Your bulbs don't look that bad and seems to be just in the early stage of stag. If you don't have or don't want to use those mentioned fungicides. Try to clean them up as I stated above and wipe the whole bulb with hydrogen peroxide. Remember to ONLY use one cotton ball per bulb so that you won't be spreading the stag further. Then OBSERVE them and keep the bulb (not the soil) as dry as you can.

NOTE: When you peel your bulb's scale, make sure that you also peel away the thin film-like skin. Stag can hide in it.

Next time you purchase a hippie bulb, inspect them asap! Report/Complain to the seller if you find stag in them. We do not deserve to receive bad bulbs. They have been doing this for years. It has got to stop!!!

Thanks Maria - just wondering, but is it not true that a slight bruising of the bulb can cause it to have a reddish mark or blotch?

A bruise would give the bulb a definite red mark that stays that way and does not spread. A blotch would be tiny red dots that would increase and eventually become a red markings. Take a look at pics above. Notice the red dots on both scales and neck. Those are not bruise marks but Stag.

Our dearest forum friend Charles (Barnhoorn) has patiently helped me a lot with my battle with Stag during those days. Identifying problems, what caused them and adviced treatment procedures through the pics I sent him. You gotta love Charles!!!
