Hello everybody,
I want to try Spinosad (Yates Success Naturalyte Insect Control) on my citrus trees to kill leaf miners. Is it safe for citrus trees?

A good teaspoon of vegetable oil and a drop of dishwashing liquid in a small litre spray bottle and you're away.
If you really wanted to spend you're money, go for something like eco-oil or white oil.
Spinosad is more for caterpillars, although I see it's the active ingredient mixed into mollassas in the Eco Nature lure product for fruit flies.

Thank you John but the larvae of citrus leaf miner are caterpillars.
White oil does not work well and you can easily burn the new leaves with solution.
Neem oil is expensive.

I use a teaspoon of Hortico Tomato dust into a litre of water, and a bit of soap and white oil.
I spray this on everything
Tomato dust has Spinosad, Sulfur and Copper so its good for just about anything and is a cheap way of making a spray.

M Nash, you may want to double check your Hortico product. I had an old container left behind by the previous owner and it contains carbaryl, which was finally withdrawn by APVMA because it is a likely carcinogen. Yates own Hortico and I don't believe Hortico still produce a tomato dust product.

Hi Chris,
True, the OLD tomato dust used to have carbaryl in it, but the newer tomato dust does not. It's just like M Nash says :-)

I still have it, I knew it was ba ju ju and respected it like wise with proper PPE. I think now I will only use it on non food plants and only when I get a serious pest outbreak like grasshoppers.
The Mix I mentioned above seems to be keeping things in check. I also read somewhere that Spinosad is listed as organic, One of those organic magazines I think. But dont hold me to that.

Hi everyone,

I have a lime tree and blood orange tree that have been hit by citrus leaf miner pretty badly. The damage appeared literally over night and all of the recent growth is affected. The leaves look ugly - can you just pull the leaves off and new ones grow in their place or should you prune the branches with the damaged leaves back?

Any advice is welcome.

Charlie

Charlie, they've hit my lime tree hard too, but not any of my other citrus, incl blood orange.
You can prune them off. Don Burke says the tree will still grow and set fruit if you leave it. I'm more inclined to leave it on a young tree.
Protect the growth flush with a spray, because the mature leaves are generally not the prime target and are never as badly affected.

Thanks Chris,
I have read the same information about the damage not affecting the growth and setting of the fruit - it is just and aesthetic thing.

I had been watching expectantly all summer and was going to act at the first sign but they were too quick! Will have to start spraying sooner next time a flush of growth happens I guess.

Our very small buk choy plants are showing leafminer damage and leaves are being removed. Is there a safe control? Maybe nearby weeds are a host?

Some of my brassicas are also affected Don.
It is not the Citrus leaf miner causing this. Different miner, same sort of result, though the leaves don't curl.
On broccoli and cauliflowers doesn't matter so much, as the leaves aren't generally eaten.
Personally I cover young seedlings, as the miner is most active Feb-March here on the brassicas. Keeps out white cabbage moth.
They generally leave the mature leaves alone. But yes it is a problem. You could lightly squash the caterpillar if you can see it on the reverse side of the leaf.
And yes, a weed I call milkweed and other thistle weeds I have seen around here severely attacked by leaf miner during the year.

My comfrey has been attacked badly by a type of leaf miner. Took me ages to find out what it was.

It doesn't leave squiggly lines like the leaf miner I'm familiar with, but sort of transparent windows all over the leaf. Haven't used anything, just pulled off the old leaves and nuked them in the microwave.

But it keeps coming back, so I'm going to have to get serious and treat it.

Nowadays what I can find is Yates tomato and vegetable dust. 0.5g/Kg spinosad (+ copper oxychloride and sulphur).
500 gram of dust for $10.98 at Bunnings.

Thanks to M Nash above for his info about using it as a spray.
