Can anyone give me some advice on a disease that is affecting some lillies. I think they're tree lillies (Gift so I am not sure). The leaves have all been chewed or have died back. The buds are dry and black. Sorry the photo of the buds isnt a great one. Appreciate any advice. Thanks a lot.

(Botrytis elliptica) (grey mould) Symptoms Leaves typically show elliptical shaped spots. The tips of the leaves are often infected. Lower leaves become shrivelled especially on second year infection. Infection can get into the stem and the whole plant collapses. In damp conditions a grey mould can be observed over the surface of the effected part of the leaf. The disease is not known to normally attack the bulb perhaps partly because the bulb is generally planted deeply. Occurrence is common. Control Lily Disease or Botrytis Elliptica is a wet weather disease. The spores are dispersed in the wind, when they settle they will germinate in droplets or a film of water and given time try to penetrate the leaf. Keeping the plant as dry as long as possible reduces the risk of infection, IE a sunny well ventilated spot. Botrytis elliptica is supposed to be different to the grey mould that effects most other plants (Botrytis cinerea) and is specific to Lilies. Although Botrytis elliptica is quite widespread because the spores can spread considerable distances, as distance increases the number of spores are reduced and therefore the chance of attack. Even short distances between plants will make a difference. When planting lilies in the garden planting in small groups with other plants between reduce the chance of spread. from pests and diseases of lilies

I'd put a carrier bag over that infected lily stem, and cut it. Then I'd use a fungicide on the others in the clump, and give a liquid feed.

Thank you so much for the advice. 3 batches of lillies (4 in each batch are affected) and they are in 3 very different areas with only one being closed off on 2 and a bit sides, the other 2 are out in the open in a sunny spot (when we actially have some sun). Its very sad. Thanks again
