For a complete elimination of insects listed below, and for ultra safe personal protection, use a good horticultural oil.  It eliminates most all common insects that attack citrus. Can be sprayed between 32F to 90F.  Insects NEVER become immune, no matter how often or how long horticultural sprays are used.  Be sure to keep ingredients (water & oil) blended while spraying

Insects killed:
Rust mite, red spider mite, scales, white fly, thrips, mealy bug, aphids, Greasy spot, loosening of sooty mold.
my biggest problem in western australia is CLM.....they are a right pain....i dont even feed my citrus in autumn because clm will just decimate it...tried eco oil and neem oil and they just treat new growth like CLM candy........spring is where its at for me..before they turn up...they love the urea apparently.

Do they have spinosad down there? Works well for leaf miner here, or you can just not feed after spring as an alternative.

Can you give a little more details how to use spinosad?
How many times to repeat the spray?
To Spray the whole tree or just the growing portions?
What month to spray (or when you see the new flush?

When using oils can you add to them a foliar fertilizer?

I'm asking after the fact that I've already done this but i want to know the thoughts of the experts. The other day I sprayed most of my trees with a sunflower oil and dish soap mix that I've been using for the last couple years. 1 part liquid dish soap and 2 parts oil, shaken to emulsify and added to water, 1 tbsp or 15ml/L of water. I added an organic foliar fertilizer with chelated micronutrients to kill two birds with one stone. Did I do something wrong? In my head the soap that helps the oil stick would also help the fertilizer stick to the leaves

Ultra Fine horticultural oil (the brand I use) vaporizes off of the leaves in approximately 1+- hours.  Therefore, it does not clog the  stomata for days and days, letting the leaves to breathe.  Various cooking oils remain coating the stomata for longer period of time.

Yeah...ive been going more for the concentrated form of feeding in spring to get as much growth as i can before the CLM turn up in the warm weather......i will have a look for spinosad here then....up to now...i use eco oil and neem oil with a little fish emulsion....but they just murder new growth...esp on lemons......its the urea they seek.
