I concluded that the fungicides mentioned higher up are non for sale inwards Great Britain because they are deemed to live also toxic. I believe this to live overly cautious, but it is smashing to see that it Pb to rigorous experimentation past the Royal Horticultural Society at its Wisley Model Fruit Garden (Surrey, southward of London) to find ways to avoid Curly Leaf inward an organic way.
The totally reliable method they came upwardly amongst was derived from an observation made earlier inward this web log post:

The incredibly unproblematic truth is that, if you lot make sure as shooting that your stone fruit tree is non rained on at all between when it drops leaves as well as when buds open upwards (roughly May to September in Tasmanian atmospheric condition), you lot will non get curly leaf.
On the Royal Horticultural Society spider web page it says (banker'sec pecker: dates are for Northern Hemisphere):

Most infestations transcend because trees were not sprayed, or sprayed every bit good late, or areas on trees were left un-sprayed. So what practice you lot practise if leaves commence to demonstrate the signs of curly leafage?
Do NOT office the fungicides described inwards a higher place in ane case flowers in add-on to leaves have got budded. You are only besides slowly AND your sprays may impairment young increase, making the task worse.
Many people claim that cutting affected leaves from the tree too collecting affected fallen leaves is the way to movement. If you lot do this, place them inwards the rubbish bin, non inwards your compost heap.
However, researchers institute that this has footling or no effect on fungal spore count. If it makes yous feel ameliorate, by all agency locomote ahead, but don’t accept away all leaves if the infestation is bad. The tree may drib dead.
If illness problems are severe, keep tree wellness also vigour past times thinning more than fruit than normal, watering regularly (avoiding wetting the leaves if possible) and feeding organic fertilisers high inwards nitrogen inward monastic society to assistance the tree to recover.
