Help Identifying Pests on Loph
    #18940423 - 10/06/13 01:52 PM (10 years, 4 months ago)

Hey All,

My l. diffusa graft seems to have some pest and they are starting effect her health it seems. She has lost some of her color, seems to be more grey as opposed t blue green. She is also developing some reddish white film on her skin, as well as what look like little holes.

From the research I have done the closest pest I can link to the symptoms are spider mites, but I am finding no webs on the cactus. The pests themselves don't look like mites either. They are white, yellow, or grey, and look more like a tiny stonefly without wings.

In the photos below you can see some of the damage, and the one with my finger in frame has one of the little bastards in it. It is the little white dot just above my fingernail. This one is quite small and usually they are almost twice that size.

Does anyone have any insight here? I suppose maybe it doesn't matter what they are as much as how I get rid of them. Thanks for any help.

When I have mites on lophs, I don't see webs.. Their web can be found usually after their colony is huge and so on.

Also I think I see simple puncture wound on you cactus.

After closer inspection I think they may be Thrips. The damage has accelerated over the past week, which prompted me to un-pot the her and rinse thoroughly with some soap and water. It has been drying under a fan over the past couple days and I am going to re-examine her tonight.

Does anyone have any advice for battling thrips? I plan to rinse again to help get rid of any lingering eggs. then re-pot in a new pot. Is diatomaceous earth advised? Neem?

Thanks for any advice.

Neem oil would be the one to use. It will kill on contact and offer some systemic protection as well. Be sure to test a spot on the plant first to check for any Phytotoxic reactions. Also don't spray in full sun, once sprayed leave it in the shade for a few days. Sometimes pesticides can dissolve or weaken the waxy coating that protects the plants epidermis from the sun.

If you don't mind using non food safe insecticides I would apply an Imidacloprid based product. It's a systemic that will poison any thrips feeding on the plant. Using this type of insecticide renders it not suitable for consumption.

I have every winter similar type of epidermis coming to lophophora, I have try control it with neem oil but direct contact at the moment isn't an option cause I don't water anymore lophs.

At summer when humidity is high they grow new epidermis but since I have got this issue every winter no matter even I use systemic pesticides and also add neem to plants.. Still skin of the lophophora seems they are not well over.. Especially loph. diffusa and fricii are taking always spider mite or similar type damage over winter and when growth season start, problems go away and they grow new epidermis..

Again my lophophora plants starts to have skin injury some of them lots, some smaller amounts or not much at all.

I am almost sure there are spider mites in my plants, at summer when it's more humid they seems to disappear but winter time they are pain in the ass for me cause they ruin my lophophora.

One thing I have notice is that when environmental light and also soil change, skin can go ugly but year or two after, when plant is used to new environment and soil they seems to have fine epidermis.

I suspect as well as spider mites and sometimes environmental changes. I have find out that different nursery obtained lophophora plants react differently just for environmental changes and problem goes away when lophophora has grown few years in new environment.

Anyway, depends totally of nursery and size of lophophora what happens to skin when I obtain new plants. Some stay very fine, some seems to suffer when I get them to my windowsill. Usually the bad epidermis goes away as I said after few seasons. Still winter time is spider mite problem to me always and I have give up, just trying to prevent them not spread too much cause possibility to get rid of all spider mites seems impossible cause they get back every winter.:shakefist:

So, after un-potting, washing, and letting her dry under a fan for a few days I have her back in a pot and have given her a little drink. The damage to the top nodes is pretty severe. I dont think rot has set it, but the scarring is significant.

I'm trying to decide now if I should just start cutting the buttons off and trying to rood them individually. Any advice?

Well if you want individual buttons then I suppose you could do this. Having a plant as substantial as that I would be hesitant on cutting it up, you'll ruin it. I would leave it be, hoping it continues to grow well. I would only cut it if I had to. The scars will eventually be hidden or less severe as the plant grows over the years.

That aint no scarring buddy. Looks like rot. Rot that has overcome so many of my cacti. Start cutting and dont stop till its all under control. If its mushy, it may be too late.:sad:

It might be rot or recovered rot. The description the OP gives doesn't indicate this. Is the affected area mushy or firm?

These things(lophs) are fairly resilient and usually recover. If the rot/bruising has subsided and flesh is hard I see no reason to cut it up. If it's still present or makes a comeback then cut it to save what you can. Just my 2 cents, I like to give the plants a chance to recover on their own before cutting them up. Once cut you lose a mature plant that takes years to recover to its prime. Blemished plants I can live with, butchered ones I cannot.

I had half a large caespitosa rot earlier this year. I withheld water, removing nothing and the affected buttons dried up and now the plant is growing fine.

If this plant was in a humid environment I would consider cutting it.

The area is somewhere in between mushy and firm. There is some give when i push with my finger, but the skin does not break, nor am I able to push my finger through the skin. It's about the same feel as pushing on a medium-rare steak (if that gives you any sense, haha) The brown, scarred, skin feels leathery and is dry.

After I un-potted and washed the plant with soapy water, the skin that looked like it had been eaten by pests started to flake off, a bit like sun burned skin. I carefully peeled off the pieces of skin that were sloughing off, and that is what dried and turned into the brown leathery  scarring in the photos above.

As far as I can tell, it doesn't look like it's rotting to me. I am concerned about the appearance of the reddish, brown patches on the skin. This seems to have spread a bit since I rinsed. Any idea what the red/brown skin discoloration is? attributable to thrips or mites?

Unfortunately I cut her up tonight. The whole cluster was rotting underneath, where the first graft attached to the stalk. It looked very woody and fibrous, not super mushy, but definitely soft. The whole cluster kind of sloughed off when i applied a little pressure :frown: So, I tried cutting the rotting base off of each of the heads as best i could and put them under a fan in a cold room in the hopes they will callus and root.

Quick question: If after cutting the rotting neck off of a rotting button the vascular ring shows some red/brown dots, how likely is it that the button will succumb to rot anyway? Another way of asking this question is, if the vascular ring is not completely free of signs of rot (reddish brown color) is it certain to die?

Thanks for your help. Really bummed to have had to cut this specimen up :frown:

Generally you want to cut back until clean. I have calloused off a few buttons before with small specks of red, but it is partly then a race against time, to get the flesh dried out before the rot can reestablish.
