Orange tree pest help w/ pics

13 years ago

Ok, i am as we speak, at my elderly aunts house. She is settling her affairs and she wants me to start a tree from a limb i have taken off her orange tree (some kind of mini orange, variety unkown, she recalls it as bitter) that is 40+ years old, probably more. i think i will be able to grow the limb on its own roots... on that side im good.

I have never had a citrus other than lemon before. is there any fact i need to know now about them? Don't oranges have to get proper sun to develop flavor (might explain bitterness, its not a trifoliate. I couldnt find the graft, there might not even be one on it, so i don't know if it is a sucker or not.

It is a very vibrant, healtly plant, no yellow leaves, several mini oranges growing on tree (but not on my twig. All the leaves are bright green and mildly to highly fragrant, some leaves have a stronger smell than others.

It does have some kind of pest though, definatly some kind of scale, its white and flakes off very easily. Appearnce of dead skin cells.

Help requested: general pest help and identification

can someone attempt discern what kind it is?

sorry, i didnt add all the info i thought i did. It also had the trademark sticky sappy coating on leaves.
New info: when i got home, i picked off some heavily infested (to the point that whilr they were developing, they got scale sucked, and came out severely deformed)I also thoroughly washed it when i got home. I washed all the dead-skin cell things(eggs?), sticky honeydew stuff, and i searched for scale bugs, but i could not find any.

Pests on a tree outside, danger? W/ Pics

Can you contact a local county extension office or university horticultural program to ask what pests are in your area? I would be pretty nervous about putting my plants near those guys too. If they are confined to one tree (or kind of tree), you may want to consider removing it. In my experience, plants aren't often overwhelmed by a pest like that unless they are already weakened by other things like disease. Sorry I can't offer more specific advice. It's best to find out what they are before using any pesticide.

John. If your growing using compost and organic fertilizers that "weakly weekly" method does more harm than good to the beneficial bacteria in the soil. I would suggest a slow release organic fertilizer and, if you need to, an organic liquid micro formula. Also if your soil Ph is too high OM and elemental sulfur will eventually bring your Ph under control. Its the use of chemical fertilizers (ie Miracle Grow and the like) that over time depletes your soil of anything organic (including earthworms, mychorrizae and beneficial bacteria) eventually the only thing that helps your plants is the "weakly weekly" method because your plants become so dependent on the chemical fertilizer due to having nothing of substance in the soil. I used to use chelated fertilizer in my soil until I began reading the soil forum. The good thing about organic gardening is once you get your soil established you rarely have to feed your trees as most of the nutrients your trees need is in the soil. The only time I use liquid soluble non organic fertilizer is in my containers and pots. For my in ground trees I have begun a schedule of using compost with %10 worm castings twice a year, tree specific organic fertilizer with chicken or steer manure and beneficial bacteria with mycorrizae 3 times a year covered with pine chips once a year. I also purchased some earth juice micro blast just in case I see micro deficiency. And to help bring down the Ph of my soil I have been using an elemental sulfur blend combined with compost and OM. I figured my soil had been depleted so bad from my grandfather using nothing but chemicals over the last 40 years that I would bring the soil back to its natural best. So far things are looking good and more earthworms are returning. I had ZERO before so any is a plus:-) To answer the OPs question...If your tree is small enough you can just squeeze the CLM (youll find it on one side of the leaf kind of wrapped in it) with your fingers and they will pop and die. No need for chemicals. Here is a link that might be useful:

Thanks serge, I guess it could possibly be. I haven't noticed any "oozing" like the symptoms or pictures show and it's not anywhere on the trunk. Since we are in a rental, would you suggest to tell the landlord or is this something that we should try to handle?

Hello Andrew,

Andrew here(Awesome name!) and I do know of a great website that may be able to help you. If you go to Four Winds website, they have link that helps ID citrus pests. What makes it so great is that they have awesome close up pics and they might just have pics of your bugs. I ID a form of scale that I had on my Oro Blanco grapefruit tree. I have sprayed at least 4 times this year and I am going to have to spray again tomorrow. What sucks for me is I have to spray all my tropicals and tropical fruit trees. Just in my bedroom alone, I have over 100 plants total. The good news is that I have been able to isolate the pests to that room. I sprayed with pure rubbing alcohol and that did the trick. Unless you use a systemic in which you won be able to eat any fruits for a year, you will only be able to manage them, you wont ever get rid of all of them. I had people here tell me this beofre and I didn't believe it but I do now!!

Next fall right before you bring in your plant, spray them all a few times with fish emulsion and you may be able to avoid the problem all together.

Hello, Andrew and Andrew! ;)

The Fish Emulsion should be available at any hardware store or nursery.
I even see it at places like CVS/Rite Aid pharmacy.

Hi Andrew:

I most defiantly would make a direct question to "Rhizzo" or "Jean" since they may not even be aware of this problem you are having.
I would also look up the Pest and Disease forum since that is where they hang out, and ask the same question there. I can guarantee that you will be helped as fast as lightning since they are just two of many that are always willing to help. They are usually spot on too.

I wish I could help, but I have never seen this type pest before and you want to make sure you treat it with the right pesticide if they are pest's.

Do they leave a sappy or sticky residue on the leaves anywhere?
When did you first notice them?
What affect are they having on the leaves?
At what temps do you grow them?
What is the coolest you can grow them at?
Have you tried any sprays yet?
Are the trees small enough to wipe these things off with a cloth and water?

Sorry for so many questions, but I like a lot of detail:-)

Let us know, ok.

Hope you are doing good. We can keep these thread going if you wish too. It seems everyone take a break about this time of year, but I find this forum very fulfilling when winter slows me down.

Mike:-)

Has your aunt ever mentioned an infestation of whitefly? These look more like whitefly nymphs than scale insects. Or perhaps scale AND whitefly. Obviously, we can't see anything on 3 of the 5 images.

Some scale species and whiteflies all excrete that sticky honeydew
