    I want to buy a fungicide but see that wickes sell sprays that are said to be able to control fungus and kill pests such as aphid. Is it possible for one spray to do all this ?

    The Doff Universal is a soap solution with a low concentration of a couple of preservatives.
    The Rose Clear contains fatty acids (will kill insects) and Sulphur which will reduce fungal problems.
    Neither will totally cure any problems you have.
    The Rose Clear states reduces blackspot and powdery mildew (not cures) and says only use 6 times a year. The label says to spray early or late to avoid harm to bees.
    I wouldn't use either and would look to treat with cultural methods, prune/thin to increase air circulation, clear up infected leaves to avoid reinfection, water in dry periods to reduce stress.
    You don't say what you wish to treat either which plants or pest/fungal issues.
    Aphid population generally increase and then drop off as predators and disease move in.

      It's for peach tree leaf curl. It was pruned over winter and I don't want to prune it now as it has some peaches. I will prunr more harder ik win
      The leaves are falling off though so I don't think i need to pull them off. Watering frequency will definitely increase. Im sure I've seen ants and aphids which is why I'm attracted to these solutions that say they do everything

      You have a problem there then. I eventually dug up my pear tree as year after year it suffered from the same leaf curl problem no matter what I did re the above cures. Or try moving it. I had no room to move my pear tree.

      Peach leaf curl Control the RHS says this:

      Non-chemical control
      Where peaches are grown trained against a fence or wall, a rain shelter of plastic sheeting is very effective at preventing infection. It should cover the top of the tree and the front to within 30cm (1ft) of the ground, but with the ends open to allow access for pollinating insects. It should be erected after leaf fall in November and kept in place until mid-May. Keeping the emerging shoots dry in this way prevents infection and also gives useful frost protection. It is used successfully every year in the Wisley Model Fruit Garden.

      A diagram of how to make the lean-to is available as a download below.

      Prompt removal of infected leaves before the bloom of white spores appears will help reduce the amount of fungus carried over to the following year.

      Some resistance is claimed for the peaches ‘Avalon Pride’, ‘Red Haven’, ‘Harken’, ‘Dixired’, ‘Redwing’, ‘Advance’, ‘Hylands’, ‘Robin Red Breast’ and ‘Rochester’.

      Chemical control
      There are no fungicides available to amateur gardeners for the control of peach leaf curl.

      A couple of things to note; you need to clear up all the fallen leaves, not leave on ground and the products mentioned earlier won't touch the fungus infection.
      If you really want to do something about the ants and aphids then an organic insecticide will help.

        Pear tree leaf curl is normally caused by a leaf curling midge not a fungus.
        Peach leaf curl affects peaches and close relatives such as almonds, nectarines and apricots.

        This is the first year but im also wondering if it's due to the stress of making peaches. It's never produced a single peach before

        Peach leaf curl should not be confused with leaf rolling aphids, peaches get both in my experience, peach leaf curl makes the leave thick and they go reddish in colour.
        I'm finding less peach leaf curl this year due to the dryer spring, it's always worse in wet years.
        I don't think Rose clear is cleared for use on edibles .

        If you just have leaf rolling aphids there is probably a systemic insecticide that is cleared for edibles that you can use.

        This is peach leaf curl, the fungal problem. 20250531_115706.jpg

          Peach leaf curl is why farmers in Kent trialling apricot and nectarine production are growing them on a dwarfing rootstock in large poly tunnels.

            @hi2u_uk could you posts photos of the problem then we can give better advice. If it is peach curl then you don’t need an insecticide and there are no suitable fungicides available for home gardeners.

              The leaves in your photo look like either a touch of sun-stress - where too much sun causes the leaves to lose moisture faster than the roots can replace it, so they droop. As they mature, the leaves toughen up and it won't happen.
              If it is that, then the leaves should look OK first thing in the morning before the sun heats them up.
              Do the leaves look like that early morning?

              If it's not then then maybe not enough water at the roots.

              It looks like the leaves are just a bit droopy to me.

              If you spray the aphids off the plant with a hose, then the ants will go too.
              Repeat every few days until they're all gone.
