Insecticide and fungicide all in one - is this possible

I think at the bottom of your picture there could be some leaf rolling aphid, but I dont see leaf curl, And I agree with @Pete8 that there maybe a watering problem.

 

Sorry, when you mentioned that been a few weeks ago I thought that was before your current problem as there is no evidence of any insect or fungal problem in the picture. As said already the leaves do look droopy so agree that it looks like it needs more water and/or more shelter from any wind

 

I will increase the watering but I was thinking of applying antifungal and insecticide treatment as well just in case they were an issue

 

I never spray anything I'm going to eat.
Even if I get some perfect fruits from a plant that I've sprayed, when I eat the fruit I'll be thinking 'I hope there's no insecticide residue in this' - and that would spoil the moment of deliciousness.

 

Do you ever buy any fruit or veg?
I only ask as when I was working, the fruit farm sprayed the trees about ten times in the growing season with stuff we cant even get hold of.

 

If you don't have a definite identifiable pest/fungal problem you will just be wasting money and time.
The good news is that most modern insecticides, fungicides available to the amateur gardener don't do much damage to the environment and a lot of them don't work very well either.

 

I buy lemons and limes but that's about all - maybe a pomegranate or avocado now and then.
I froze 27Kg berries last year and I have 3 apple trees and 4 pear cordons.
So there's rarely a fruit shortage, as it's all for me

But veg I do buy - lots of it - but it's not the same as home-grown

 

I have very low expectations for the amount of peach I will get. Also I'm pretty sure cats and foxes use the place as a toilet

 

The location and the actual site of the tree will also be a big factor in how much fruit you'd get.
For example, there would be no chance of getting peaches where I am, unless they were being grown undercover, and with a fair bit of help. Even with the abnormal weather we've had here recently, it wouldn't be enough to ensure a reliable crop.
I'd agree with what's already been said though re pests/diseases, and your plant.

 

sorry i was being a bit unclear, the tree actually has some peaches on it they have been there for the past 3-4 weeks or so. What i meant is that i dont think they will meet the standard of peaches that i would eat. The tree is definitely not grown under cover. If you look at gardening websites in other countries these say that they actually need cold weather to fruit and need water .

 

Why wouldn’t you eat them? Homegrown peaches are delicious as you can eat them when they are perfectly ripe. If the skin is blemished or covered in sooty honeydew, ripe peaches are very easy to peel. The skin will simply peel away

 

all the insects that have probably been crawling around, then theres the cats, foxes and squirrels and goodness knows what that have been using it as a litter tray. Im always very concerned about plant feeds are they are not very specific about what exactly is in them. I get the feeling some put artificial hormones in them but they arent clear about what exactly the hormone is . Even the ones that just say nitrogen potassium etc the labelling never says what exactly is the source of the nitrogen . Food , medicines and even my washing up liquid has better labelling about their contents that the plant feeds ive seen .

 

I assume you don’t eat any fruit at all then as all those concerns would apply to any you buy. At least you can control some of those for homegrown fruit.

The only feed our peach tree gets is a annual mulch of home-made compost

 

I'm not aware of any plant feeds that contain artificial hormones - why do you get the feeling that they do contain them - and what would be their purpose?

A molecule of Nitrogen (or phosphorous, potassium) is exactly the same irrespective of how it was produced, so ALL nitrogen molecules are identical.
For plant feeds nitrogen is made from ammonia, which in turn is made from air and hydrogen.

I think you're worrying about things you don't need to worry about

 

Peach leaf curl usually develops bright scarlet blisters on the leaves.
