Leaf Curl On Nectarine Tree

Leaf Curl On Nectarine Tree

Hi Team,

 

I have a perfectly growing nectarine tree in my backyard. Every year it gives plenty of Nectarine. For last 2 years I see the leaves curl up and the fruits get some fungal infection.  Anything I can do to prevent this from happening ? Please let me know what to do

Hi @iamtheroot,

 

Leaf curl is something that you need to get on top of prior to buds swelling. Before the buds swell it is a good idea to spray with Yates 500ml Lime Sulphur Concentrate. Just a warning this product does not smell particularly great. This is followed up by spraying the tree when the buds are swelling/opening (late winter) with a copper-based fungicide like Yates 200ml Liquid Copper Fungicide

 

This disease lays dormant over winter and it is noticeable in spring. You are too late for the sulphur treatment this year but I would still encourage you to apply the fungicide. Next year I would get on top of this early and do both the sulphur treatment and the fungicide.

 

Let me mention our resident gardening experts @Noelle and @Adam_W to see if there is anything else they can add to the conversation.

Re: Leaf Curl On Nectarine Tree

First spray (lime sulphur) should be immediately after pruning in mid to late winter.  Agreed it's too late now but the copper spray will inhibit the fungus maturing and shedding spores that will catch in bud scales and bark crevices before next winter.

@Noelle  so I can safely use Yates 200ml Liquid Copper Fungicide  now ?  quiet a lot of fruits  now so this fungicide is safe ?

 

Thanks

@iamtheroot,

 

I believe copper-based fungicides are safe to spray directly on the fruit. You might find there is a with-holding period where you shouldn't pick for a few days after spraying and as always wash the fruit well.

 

I'm sure @Noelle will be able to tell us if that is not correct. Alternatively, if Noelle doesn't get back to us I'll contact Yates after the weekend to verify.

Re: Leaf Curl On Nectarine Tree

Copper-based sprays are safe to apply at this stage - it will be quite some time before the fruits are ripe enough to pick and eat! 

 

Yates Leaf Curl Copper Fungicide has a ONE DAY withholding period.  A good idea with any garden chemical to always check out the manufacturer/wholesaler website for accurate info.
