Hi Everyone,
I was wondering if you could help me with information for an assignment I am writing for the pest and disease module of the horticultural course I am currently studying. I am looking at the significant P+Ds which affect commercial Narcissus production within the UK and am struggling to find the current control measures for the following problems:
• Large narcissi fly, (Merodon equestris)
• Stem eelworm (Ditylenchus dipsaci)
• Bulb scale mite (Steneotarsonemus laticeps)
• Leaf scorch (Stagonopora curtisii)
• Smoulder (Botrytis narcissicola)
• Neck rot (Fusarium oxysporum fsp.narcissi, Botrytis narcissicola and Penicillium hirsutum)
• Basal rot (Fusarium oxysporum f.sp. narcissi)
a large proportion of the information I have gathered uses chemicals which are now banned from use within the UK, and I have been unsuccessful in locating up todate treatments via the internet - I'm sure it is in there somewhere
I would be grateful for any help you can offer me in trying to locate this info
Cheers
Susan
