I was wondering if i should spray my peach tree for leaf curl, there seems to be sign of it but isn't the purpose of sraying them to protect them from getting it. Also if i should spray, do i just use a general fungicide and at what times do i spray it?

where are you located?

We spray peach curl 3 times. One just after leaf fall (around thanksgiving time in our area), then one during the middle of winter (combined with oil for insect control, about Christmas Day) and then during budswell to pink stage (around super bowl time).

If you have peach curl now, there's nothing you can do to prevent the current disease, but you can prevent it next year as suggested above.

And here's the tip I posted elsewhere:
This spring time, when we have visible damages to the leaves, it is
too late to apply treatment. Ultimately the infected leaves will fall
off stressing the tree and weakening it. Removing the infected leaves
is a futile effort and will not improve the tree.

But there is something we can do to help out the tree. When it gets
warmer and drier later in the season, remove most fruits, apply 50%
more nitrogen fertilizer the old cheapo bag of ammonium sulfate to
encourage vegetative growth spurt. Also apply epsom salt along with
it. This would help alleviate the stress the tree undergoes when
losing its leaves to peach leaf curl.

Come fall season, be armed with a full dose of fungicide, and you may
need to reapply once again during the bud break.

The fungicide part I have faithfully done but it seemed futile because
of all the cool rainy days we are having, the temperature ranges
(50-70 deg F) is a paradise condition for the causal fungus, along
with slow leaf growth and extended wet record breaking rainy days,
there is no fungicide that will work 100% this season. But compared to
my neighbors, my trees are still well off.

Like you, my best recourse at the moment is to wait it out, and apply
a mixture of ammonium sulfate and magnesium sulfate (epsom salt) by
late spring when it is drier and warmer and the peaches starts to
extract nutrients from the soil. Fortunately, these fertilizers are so
easy to melt in a plastic bucket. I would be using 2 cups (about 1 lb)
of ammonium sulfate and 4 oz of epsom salt on a 5 gallon pail of
water. Will perhaps apply 15-20 gallons spread around the base of the
tree. Apply more if you have a bigger tree, but the dilution above is
not harmful to the roots of my trees. This should perk up the tree to
develop more greener and bigger leaves.

well it doesn't have peach curl i am most sure but i just bought and i haven't planted it because we have gotten a lot of rain lately (it is drying up now) and the ground is soaked. I live in southern ontario canada and i would say the times for the leaf fall and bud break are a lot differnet then for you. So is it too late for spraying so just incase it get the curl or should i just what until the season is over and spray in fall?

For now, you don't need to spray until the fall.

If you don't have a lot of disease pressure, you only need to spray once. Lime sulfur is the more effective fungicide but don't spray apricots with this stuff. If you need to spray only once, make it during the 90% leaf fall. When you have very few leaves left on the tree, then spray just before the heavy rains come. and if the rains have already come before you spray, look at the forecast and when you have the very first one week rainless day forecast, spray at that time.

Alrighty thanks for the help i am a lot less worried now.
