Strawberry Leaf Problem

[bendipa]

I've noticed that the new leaves on some of my plants are affected by what appears to be a rot, which starts from the edge of the leaves and works inwards killing the whole leaf eventually. I had this trouble last year which resulted in the death of nearly half my plants. The affected plants have been growing strongly and produced plenty of flowers.I can't see anything on the web which resembles the symptoms exactly, which seem to have suddenly shown up in the last 2 days.

The affected plants are all neighbouring ones in a trough. I have other strawberry plants in another container several feet away from the problem and so far they have not been affected. I've decided to spray the affected plants with systemic fungicide while the problem is in its early stages. I'm not sure whether the problem is soil or airborne. The photos of the symptoms are shown below.

Does anyone have any idea what the problem might be, please?

I have the same thing on some of mine - I thought they were just getting a bit burnt in the sun but thinking about it now I have lost some of the weaker plants already - just went brown leaf by leaf and then died.

I wonder how deep you've planted them? The crown mustn't be buried, if it is the plant will die

ts is right i just took a look at your strawb planter chitfaced and alot of the plants i couls see are buried to deep if you bury the crown the plants will rot you must keep the crown just above the surface of the soil and then you should eliminate this problem .bendipa i could not see from your pics but you should check .if you have buried the crown remove some earth and leave exsposed hope all works out for you both.i will put a pic up so u can see what i mean .also put pick of a few of them sending runners thought it way to early for that??but the plants know best bt will cut them of for now i want strawbs for now will let runners grow on the more established plants latter in the summer

No. that's not the problem. I've grown strawbs for years so I know how they should be planted. I've not seen this problem before. I think it's a blight of some kind. I've sprayed my plants with fungicide, something I've never had to do, so I'll see in the next few weeks whether the problem is arrested

Just noticed the same starting on a few of mine - I've just pulled off the affected leaves to try and stop it spreading so we'll see.

Well sprayi9ng my strawberriy plants with fungicide seems to have done the trick. No more browning of new leaves for the time being. Even the affected plants don't seem to have the browning spreading.

The only problem is that the systemic fungicide I used said not to be sprayed on food crops. Well that was a fortnight ago since spraying, and as I won't be picking for about another 2 weeks from the sprayed plants, will it be safe to eat the strawberries from these plants (4 week after spraying)?

I wouldn't risk it anything you have sprayed has been sucked up by the roots and leafs and has gone into your strawbs .there's a reason they say don't use on edible plants .maybe dehead these strawbs and wait for next crop change soil in pots so there's nothing that the plants can suck up .that's what I'd do myself just to be on the safe side .
