weed Parthenium.In our country we are also facing serious health problems due to
Parthenium.Parthenium is causing skin diseases ,nasobronchial rhinitis and asthama in men
and loss of hair ,depigmentation of skin and ulcer formation in intestine of animals.
During an exhaustive surveys work of this notorius weed we found PLO disease as you
discussed in your letter, viral diseases,mosaic and leaf curl virus,leaf blight ,root
pathogens.The pathogens of above diseases were isolated and tested there pathogenecity.The
above pathogen proved the high Dr.G.K.Awadhiya |

a long history of largely successful biocontrol of this weed in Queensland, Australia, and
we can supply all the biocontrol agents used, together with information on their biology,
host-specificity, effectiveness etc. We would of course require a permit from your
government before shipping any agents. |
| From: "Rohini Ekanayake" <ubeka@kandyan.net> Received: Wed, 15 Nov 2000 07:40:46 -0800 Dear Dr. P. Oudhia, I am a senior scientist attached to the Department of
Agriculture. I have been given the responsibility of controlling the above weed,
which has become a serious threat to our agriculture. I got your e your e-mail
address via Internet and I seek help from you with regard to biological control of
this weed. According to our research work plan on Partrhenium control, we are hoping to import potential biological control agents of this weed from other countries to evaluate their efficacy under local conditions. According to the world' literature there are six species of insects and pathogens. Of these, Zygogramma bicolorata (Coleoptera: Chrysomelidae) and the fungal pathogen Puccinia abrupta have performed as potential bio control agents against this weed in India and Australia. I managed to find some imnformation on bionomics and management of this weed via intenet. However, it is difficult to find places from where I can import potential bio-control agents of this weed. Therefore, I would appreciate it very much if you could send
information on biological control of this weed and e-mail addresses of places/institutes,
from where I could obtain the above biological control agents of Parthenium weed. |
