Our apple tree is covered with a white flaky mildew type fungi, please could you suggest a fungicide and treatment for this problem. Thank you, pic attached
It likely is woolly aphids. Try blasting the branches with water and see if that dislodges them. If that doesn't work try insecticidal soap or Neem oil.

As above we have been in the house 2yrs so this will be our 3rd crop the dead levels have only appeared this year. See attached photos.
Dieback of branches could be caused for several reasons, one of which is fireblight.

and what concentration of hydrogen peroxide should be used (3% or 35%) along with water?? Root Rotting
I don't recommend it for preventing it, so much as I do correcting it. If you want rates for prevention, I would go with 1/8 peroxide to 7/8 water once per month. That should be sufficient without burning the plant.
Use only 3%, as 35% is very hard to get down to manageable levels in the amounts that you will need.
For treating it, you will use this 1 time at 1/4 peroxide and 3/4 water. Water in once, then once again after the soil dries completely or roughly a week later.
You can also use a combination of DOLOMITIC LIME and WETTABLE SULFUR once or twice per year to prevent and treat infections, and provide trace, and micronutrients to the soil.

I have an apple and pear tree next to a fence. I never get any fruit because the squirrels beat me to it. I have tried fruit containers and bags but they knock them off the tree then eat through the packaging.
We have a couple of articles that should help you out: https://www.gardeningknowhow.com/plant-problems/pests/animals/get-rid-squirrels.htm

the leaves were not distorted or eaten by aphids, they just went completely brown & crispy
I would first suggest removing all the affected branches since those leaves have stopped photosynthesizing. Here's an article that may help you to identify and treat the tree: https://www.gardeningknowhow.com/edible/fruits/apples/apple-chlorosis-treatment.htm
There is also a possibility that canker has set in or root rot is beginning or, perhaps, a high wind has harmed those particular branches.

If these articles don't help you identify the issue, you may want to take a sample to your local extension service.

Hello, I have an apple tree in the back garden which has a growing mound of sawdust next to it at the base. There is a cavity where the sawdust is coming from, but when I put my hand in, I can only find woodlouse in there. I am worried that the tree is going to become so weakened it will fall over. Is there any way to identify (and then stop) whatever it is that is causing this? I have attached a photo if it helps Any help would be greatly appreciated Thanks Pete
Boy are you brave to stick your hand inside the hole. Do you see any ants coming and going? All my research pointed to carpenter ants. They don't eat the wood, but create tunnels in dead, moist wood, then deposit the sawdust in piles at the base of the tree.
Apparently, no control is necessary because they aren't eating the wood, only living in it. However, you may want to monitor the structure of the tree, because your tree may be more vulnerable to storm damage.

This was following an article about these trees on Gardening Know How.
We don't recommend specific retailers, but you can look online for fruit tree retailers, if your local nursery doesn't carry that variety of tree. Make sure you are getting the whole tree and not just the rootstock.
