On receiving your email to enviroweeds, I visited your excellent web site on
parthenium, but could not find the paper on phyllody by Dr Berhe of Ethiopia. Phyllody
occurs frequently on parthenium here in Queensland. We believe it to be due to a
mycoplasm, probably the same as causes disease on tomatoes and other plants, and
transmitted by a sucking bug of some kind. Typically
the whole plant is affected and produces no seed, occasionally only part of the plant is
affected and the rest is normal.
Perhaps you could transmit this on to Dr Berhe. I would be happy to discuss the
matter with him further if he wishes to contact me by email.

Dear Dr.Oudhia,
thank you for your message. if you look through the list of the literature published by me
in the site you will find that mine was the first research pertaing to "study
of allergenicity of parthenium" parthenium pollens do not cause any type I allergy
but is implicated as a cause of type III ' PETALS OF PARTHENIUM CONTAIN WHAT HAS NOW BEEN
IDENTIFIED AS "PARTHENIN" which causes the symptoms in fact we had scientist
from USA sometime back at MACS to attend the syposium who also concurred with my
conclusion furthermore for last one year we are doing routinely specific IgE titres in
addtion to other allergens listed in ARISIT ALLERGY PROFILE of our patients
on our site for parthenium pollens which also confirmed our earlier finding in fact wen
can use this specific IgE as a negative control! our metadology for assessment of specific
IgE titres is perfectly standardised and we can now confirm beyond doubt whether
any particular pollen or for that matter any other protein material can be
implicated in allergic reaction or not. furthermore we have also developed a methodology
of recovering viable leucocytes from a blood clot which can be used for "lecocytic
migration inhibition test"(LMI) This Test Allows Us To Measure
Protein As Diluted As 10 Raised To Minus 200! Using This Method We Also Carried Out
Discriminant Analysis Of Various Types Of Allergic Reaction And This Too Confirmed Non
Implication Of Parthenium Pollen In Typy I Allergic Reaction. I Will Be Very Glad To
Associate With Your Group

To : Mr. Pankaj Oudhia
Society for Parthenium Management (SOPAM)
28-A, Geeta Nagar, Raipur - 492 001, India.
Dear Sir,
I have been searching for almost a year now before I came across some
print outs of the "International Parthenium Research News Group". I have
enclosed 4 pages of notes on the "Parthenium phyllody" a
potential biological control agent operating naturally in our area. If you find it good
enough a contribution for the IPRNG it is all yours.
I also wonder if SOPAM could do some thing by way of assisting
in the identification and subsequent employment of the causal agent, for control of
Parthenium as well as providion of print outs. A list of the articles have been enclosed.
As I have no access to an internet I hope you would be kind enough to take the trouble to
communicate me through the post office. [Please click HERE for the mailing
address].
Thank you.
