Which disease.

Frog · July 9, 2009

You'd think I'd have learnt by now, but I am rubbish at identifying diseases, every year I umm and aah and dither, unsure what ailment has struck my plants.

Here are two photos, underside and overside of an infected leaf. The patches penetrate right through in all incidences that I can find. The necrotic patches are very dry and crispy in dry weather, silvery/brown in colour. The infections are localised to three plants, adjacent to one another and appear on old and new leaves, but only mature ones. No markings on fruit or stems, but some flowers have dropped, but it was over 30ºC/90ºF last week.

Any ideas?
