Dear Pankaj,
Congratulations for Parthenium website which make availability of information about
all aspects of Parthenium weed. I am also working on the same weed on management aspects
with the use of micro-organisms.One project is also submitted to I.C.A.R.(INDIA) for
financial support on management of Parthenium weed with the use of micro-organisms.The
fungus Sclerotium rolfsii Sacc. was recorded as potential mycoherbicide for Parthenium
management during my Ph.D. work.Exhaustive survey is in progress and I have recorded new
viral diseases which has enough potential to suppress the population of this notorius
weed.
I have some queries
1. Have you got any information regarding use of viruses for management of Parthenium.
2. Are there any reports regarding translocation of Parthenium toxins in other host during
allelopathic studies.
3. There are some reports about use of Parthenium extract for disease management and were
found effective against few
pathogens but crop became stunted .Is this due to Parthenium toxins? If
so then how long toxin retain in crop plants?
Thanking you,
Dr.G.K.Awadhiya, Asst.Professor, Department of Plant Pathology, Indira Gandhi
Agricultural University, Raipur-492001 India.

Dear Mr.Oudhia,
First of all accept warm and cordial congratulation for working and establishing world's
first information website on the most obnoxious weed parthenium. Moreover, the management
aspect is also being covered for which I, hope this website will bring closer and together
the different workers at one plateform and the joint effort made by them will find a
worthy solution. I will be happy to participate in the discussion. I heartly congrates and
welcome the website of International Parthenium Research News Group in cyber
era.

Dear Dr.P.Oudhia,
First of all I congratulate you for having taken up bold step in the direction of
declaring a War Against Parthenium .In response to your letter dated 20-05-2000. I
am here with sending my two publications on Parthenium for inclusion in the International
Parthenium Research News Group(IPRNG). Balikai,R.A.(2000). Insect pests of Parthenium
hysterophorus Linn. Insect Environment 5(4):179-180. Hiremath,I.G, Lingappa,S.,
Balikai,R.A. and Yelshetty,S.(1990). New host plants of Grape Mealy Bug. Proceedings of
the National Symposium on Behavioural Sciences & XIX Annual Meeting of Ethological
Society of India Held at Post Graduate Department of Zoology, The American College,
Madurai- 625 002 from 27 to 28th December, 1990:42
Please let me know whether you are taking up any publication work on recent advances
in Parthenium Management Research. If so please send details. Kindly let me know your
activities in this direction.

Hello Networkers,
I am Dr.M.P.Thakur,Sr. Scientist (Mushroom) and I/c Mushroom Research Project at Indira
Gandhi Agricultural University,Raipur(India).I congratulate Mr. P.Oudhia for opening a new
website entitled'International Parthenium Research News Group(IPRNG)' whereby the
scientists,researchers,progressive farmers and others whosoever is interested in
Parthenium Management all over the world may get an oppurtunity to discuss about the
dreaded weed Parthenium hysterophorus and its management. I am happy to inform you all
that this dreaded weed after harvesting and proper drying can be used for cultivation of
oyster mushroom(Pleurotus florida),a highly nutritious food for human consumption.We have
evaluated nine locally available substrates including Parthenium for their effect on
growth and yield of this mushroom.The numbers of days required for colonization of
substrate by P.florida was though less in other substrate including Parthenium that of
sugarcane baggasse.The fresh yield of mushroom in other substrate was
highest(202gms).However, it was moderate (156gms) on Parthenium with a biological
efficiency of 31.2%. When we picked up the first produce then it became a problem for us
whether to use the produce for consumption or not.Several scientists,biochemists and
chemists were consulted who can guide us regarding consumption of the produce raised from
Parthenium substrate.But,still it is a big question mark before us whether to consume the
produce or not.Your valuable suggestions are welcome to resolve this issue. It is likely
that the alkaloids may be transmitting to the fresh produce which may be hazardous to
human consumption. When the fresh produce of Parthenium substrate came to us,we mixed up
it with the fresh produce derived from the standard substrate in the ratio of 1:5 and
asked the consumer to use it for vegetable making.The information on taste and texture
from the test persons after consumption were collected.It was told that there was no
change in taste and texture of oyster mushroom raised on Parthenium.This way, we utilized
the produce but still the confirmation regarding translocation of alkaloids from
Parthenium to fresh oyster mushroom is unanswered and we are hesitating to recommend the
produce for human consumption.We welcome your views in this regard. Thus, it can be said
that the Parthenium may be a good substrate for cultivation of oyster mushroom provided
its toxic substance may not be translocating to the fresh produce.It can be a good step
towards its eradication and management.

Pankaj,
i read your concern abour this weed thru our WSSA Bio Control Comm. Can you send me a
reprint of its biology, ecology, control etc. Here in Canada we have a series of papers on
Bilogy of Canadian Weeds published in Can J Plant Science. I have 2 papers on forest
weeds-- scotchbroom and gorse, if interested i can mail you-- whats your address?. i know
Dr. S. Malik and Samunder Singh of Haryana doing some research. Do you find it in Canada
too, i thought it occurs in warmer climates? Sorry for my ignorance?
Raj.

Dear Dr. Oudhia,
Please add my name to your network. Although I am not now working on this weed our
Centre has a vigorous research programme on biological control under the leadership of Dr.
Rachel McFadyen. I have supervisory responsibilities for the all the Centre's
biocontrol work. Some years ago I conducted exploration for agents in North
America. Sincerely,
