Need some help with toms and runner's please.

[edd]

Hello folks.

I am new to the forum and am gratefull for the wealth of knowledge and information everyone has to offer here.

I have an allotment a rather large one I have three 16m by 6m polytunnels on site and everything has been fine until now.

Poly ones main crop is tomatoes and they were doing fine until today. I noticed a few black marks on some leaves and a few stems, I have removed all the toms from one side the other side is full of ripe and ripening fruit that has very few sings of infection ( blight ) I think, see attachment 582. today I have removed most of the leaves from them, is there anything organic I can treat them with ?.

Poly two is a mixture of crops but I seem to be having a problem with the runner beans please see attachments 576 - 577 - 578 I have no idea what or why this has happend and would be gratefull if anyone could point me in the right direction as to what is the cause of the problem and any organic remedy's to my problems.

Poly three is resting.

Many thanks for all help offered.

Regards.
