Two of my pines are suffering this same ailment. Does it look like Diplodia tip blight to any of you experts? The two trees are Pinus sylvestrus "Fastigiata," and Pinus densiflora "Tanyosho Compacta." If it is, is there anything I can do about it?

Here's the other picture.
Oops, might be the same picture, and I can't seem to find the picture from the Scots pine, but it looks just like that.

That looks like it could be a number of things.
A product of salt damage being one.
Dog unine another.
And possibly even the effects of root damage from parasites such as grubs.
Tip Blight happens (I call it needlecast) during warm weather. Around here, Pinus sylvestris and Pinus nigra are very subject to it as our summers are hot and humid which neither species has tolerance to,and while it can be held abound with natural or inorganic applications, the trees once infected with the fungus always keep the (pathogen).
What I see in your photos looks most like damage that occured from salt uptake, especially.

Hi Dark,
Dog urine could be the culprit on this small "Tanyosho Compacta." Otherwise, salt uptake would be a mystery to me as these plants are not near any pavement and I have never applied fertilizer where these plants are.
On the Pinus sylvestris "Fastigiata," the damage is higher, where no dog, especially mine, could reach.
