Something is wrong with this citrus

    17 responses

David C. starts with ...
Hello, first post here.

I have a small backgarden in Wooloowin, North Brisbane, Australia. When I moved here I transferred some seedlings that I raised from pips and seeds from the supermarket fruit and veg shop. Now only one has survived and I have attached several pictures of it. I believe it is a citrus possibly a lemonade variety and the leaves are all shrivelled. It is a great screening tree at the very least so I would like to take care of it.

What suggestions do you have to make it healthy?

You seem to have a bad case of leaf miner David. Try pest oil or white oil - the directions should be on the bottle.

Citrus leaf miner is common at this time of year. Buy (or make) some white oil and spray over the entire leaf surface.A couple of applications a few weeks apart should help - keep it up on any new growth as the old leaves won't recover.

Hello again

I read up a little about these pests (leaf miners), and I found out that you have to trim off the shrivelled up leaves as these will not repair and often still house the leaf miners. Apparently it is hard to kill the leaf miners that are already there so removing the shrivelled up leaves is a good idea. I also found a leaf miner on the tree and three caterpillars (see attached pictures). I treated the tree with this natural spray that I had lying around and as you can see it had quite alot of foilage removed.

By the way is there anything else I can do this time of year to help it through the winter?

Confidor guard works very well. That will kill them off, then trim the affected bits off.

That seems like overkill. Confidor is a neo- nicotinoid that is highly toxic to bees and remains active for years. Would not oil spray be sufficient plus/minus malathion.?

My sentiments exactly, gardenerer. Confidor is also systemic that ends up in pollen and nectar which, in turn is fed to the young bee brood which, amongst a host of other similar products using that same active ingredient, is linked to CCD (colony collapse disorder)

Confidor is not registered for citrus. In fact, if you have fruit and you have used it you are advised not to eat any of the fruit.
On young trees, probably best to leave the leaves on the tree that have been affected. Though they will probably drop off at a later stage, the tree needs all the leaves in order to keep it growing and to photosynthesise.
Removing the leaves will not prevent the pest returning next season. Not sure where you are exactly but here in Sydney, too late to start spraying as the pest has come and gone for the season. Up further north, Pest Oil/Eco Oil regularly on new flush or make your own very simply (see Gardening Australia website).

Well they certainly list it for use in citrus for citrus leaf minor. Not sure why if it isn't registered for use on citrus.

But if pest oil is so effective (and it is, in my experience), why use a nasty chemical?

i'm gonig to add my 2 cents, the consideration should be, to use the least amount of toxic/poison first. Pest oil, especially the home made version with veggie oil and a bit of detergine is probably a better alternative and relatively 'safe' to the overall environment.

I too have a bottle of confidor and will only use it as a last resort. I certainly wouldn't want my kids to eat citrus fruits laced with confidor or any form of poison for sure, even if its labeled safe for humans etc.

If you note from the Bayer link, it has a 20 week withholding period for Commercial growers only.

The leaf miner that I have in all my citrus just laughs at white oil or pest oil even when the leaflets first emerge. I apply the oil as soon as leaflets appear and if I leave applying it again for a few days... too late! They have done the deed.

Use spinosad on new growth if it's a problem on small trees.

Factoring in the cost of Spinosad you may be better off just buying your citrus . Why not just prune off affected branches?

I spray weekly with pest oil or equivalent from August through to the first frost to control variousncitrus pests, it works but dont miss a week.
Leaf miner doesnt really harm the plant, just looks ugly.

pest oil and such are now considered to clog the pores on leaves and slowly suffocate the plant - if it recovers try using Eco oil at correct dilution or bit thinner. need to do more often than on bottle but wont suffocate.
