BACKGROUND Parthenium dermatitis is the most common type of airborne contact dermatitis in India. It is a chronic disease of a remitting and relapsing course with significant morbidity and distress, but there is no scoring system to assess its severity. AIM To design a scoring system for the assessment of clinical severity of disease in Parthenium dermatitis and to use this scoring system in ...

Optimum conditions for the rapid, efficient, nondestructive determination of rubber producing potential in guayule (Parthenium argentatum) were established. The rubber producing potential may be defined as the ability of the plant material to synthesize rubber from a precursor under specified conditions. To achieve this, stem slices taken from the first 5 centimeters of branches were incubated ...

The present investigation focused on the effects of plant and seed diffusates of Parthenium hysterophorus L. on seed germination of Raphanus sativus L. Level of glucose in germinating seeds as an indirect measure of amylase activity was estimated. About 91.66% viable seed of Raphanus sativus were treated in different concentrations of rhizospheric soil diffusates (PD) and germinating seed diffu...

Parthenium density and species richness were found to be more in non-invaded (N-I) sites as compared to invaded (I) sites of Jaunpur district. pH, OC and %N of the soil indicates that the plant survive naturally at higher level of salinity. In pot experiment, plant growth, proline content, TSS content, chlorophyll, N, P and K was not significantly affected up to 1% NaCl (w/w) over the control a...

Parthenium (Parthenium hysterophorus L.) has become an invasive woody plant in recent times in many part of the world affecting the agricultural productivity. Hence we carried out to evaluate the effect of P. hysterophorus on germination and elongation of Onion (Allium cepa) and Bean (Phaseolus vulgaris). The plant extract prepared by the extractions of 1,2,4,8, and 16 gram powder in a 400ml of...

Parthenium hysterophorus L., (Asteraceae) commonly known as parthenium weed, is a highly invasive plant that has become a problematic weed of pasture lands in Australia and many other countries around the world. For the management of this weed, an integrated approach comprising biological control and plant competition strategies was tested in southern central Queensland. Two competitive pasture...

The lipophilic ̄avonoids in leaf and ̄ower of Tanacetum parthenium and T. vulgaris have been compared. While those of T. parthenium are methyl ethers of the ̄avonols 6-hydroxykaempferol and quercetagetin, the surface ̄avonoids of T. vulgare are methyl ethers of the ̄avones scutellarein and 6-hydroxyluteolin. Apigenin and two ̄avone glucuronides are surprisingly present in glandular trichomes on...

Cajanus cajan is an important pulse crop of India and Parthenium hysterophorus is an invasive weed of agroecosystem. The main aim of this study was to evaluate the effect of leaf extract of Parthenium hysterophorus of different concentrations on the rate of seed germination and seedling growth of Cajanus cajan, and to know the allelopathic effect is the main cause of success of P.hysterophorus ...

Parthenium hysterophorus L. is commonly known as “Gajar ghas" in Hindi and belongs to family Composite. It is an annual herb erect up to 1.5 m in hight. Its stems is branched and covered with trichomes. Its leaves are pale green, branched and covered with soft fine hairs. In Homoeopathy system, allergies caused by Parthenium can be treated by a drug prepared from Parthenium. Root decoction is u...

Parthenium hysterophorus, an invasive alien weed, is spreading rapidly across various land uses in Nepal. To understand how Parthenium is spreading across land uses at local scale, occurrence of this weed was recorded and its’ coverage in percent estimated along trails and road network at every 100 meter distance in Kirtipur Municipality of Kathmandu valley. In addition, vegetation sampling was...
