“…The incidence of the rust disease on parthenium in different locations under field conditions showed varied effects on morphological parameters of this weed, with seed production capacity reduced by 42%. Host specificity tests against the weed and crop hosts related to parthenium revealed that sporulation of P. abrupta were observed exclusively on parthenium, though limited number of poorly developed pustules were recorded on varieties of niger seeds ( Guizotia abyssinica ) [47, 48]. …”

Congress grass, Parthenium hysterophorus L., of the family Asteraceae (tribe: Heliantheae), is an erect and much branched annual or ephermeral herb, known for its notorious role as environmental, medical, and agricultural hazards. It is believed to have been introduced into India and Australia from North America and in the last few years the weed has emerged as the seventh most devastating weed in Africa, Asia, and Australia. The aim of this review is to provide general information about the physiology, distribution, ill effects, and management of parthenium. Control of parthenium has been tried by various methods, but no single management option would be adequate to manage parthenium, and there is a need to integrate various management options. Successful management of this weed can only be achieved by an integrated approach with biological control as the key element.

“…The inoculation process was undertaken on individual plants using a Wattyl Jet‐Pack and applied until all leaves on the target plants were wet. Using a previously described approach (Fauzi et al ., ), the inoculated plants were individually covered with black plastic bags, pre‐misted with distilled water and placed into the same growth chamber set at 15 ± 2°C, for a further 9 h. The plastic bags were removed from the pots, and the plants were incubated at 25/15 ± 2°C (day/night) for a further 35 days.…”

In this study, we used Parthenium hysterophorus and one of its biological control agents, the winter rust (Puccinia abrupta var. partheniicola) as a model system to investigate how the weed may respond to infection under a climate change scenario involving an elevated atmospheric CO 2 (550 lmol mol À1 ) concentration. Under such a scenario, P. hysterophorus plants grew significantly taller (52%) and produced more biomass (55%) than under the ambient atmospheric CO 2 concentration (380 lmol mol À1 ). Following winter rust infection, biomass production was reduced by 17% under the ambient and by 30% under the elevated atmospheric CO 2 concentration. The production of branches and leaf area was significantly increased by 62% and 120%, under the elevated as compared with ambient CO 2 concentration, but unaffected by rust infection under either condition. The photosynthesis and water use efficiency (WUE) of P. hysterophorus plants were increased by 94% and 400%, under the elevated as compared with the ambient atmospheric CO 2 concentration. However, in the rustinfected plants, the photosynthesis and WUE decreased by 18% and 28%, respectively, under the elevated CO 2 and were unaffected by the ambient atmospheric CO 2 concentration. The results suggest that although P. hysterophorus will benefit from a future climate involving an elevation of the atmospheric CO 2 concentration, it is also likely that the winter rust will perform more effectively as a biological control agent under these same conditions.

“…Namun untuk timbulnya suatu penyakit atau keberhasilan interaksi antara patogen dan inang untuk timbulnya penyakit harus didukung oleh faktor lingkungan. Kondisi lingkungan yang mendukung terjadinya penyakit terutama adalah suhu dan kebasahan daun (kelembaban) pada saat inokulasi, sebagaimana dilaporkan oleh Fauzi et al (1996;1999) bahwa suhu dan kebasahan daun sangat penting terhadap terjadinya infeksi dan perkembangan jamur karat P. abrupta var. partheniicola (PAP) bahan biokontrol gulma partheniun di Australia.…”

The pathogenicity of a rust fungus (Puccinia philippinensis Syd.), on purple nutsedges (Cyperus rotundus L.). A research aimed at understanding the pathogenicity of a rust fungus (Puccinia philippinensis Syd.), a potential biological control agent of purple nutsedges (Cyperus rotundus L.) had been conducted in a glasshouse of Faculty of Agriculture the University of Mataram. These factorial experiments designed according to Randomized Completely Design (CRD) and consisted of spore density and time of application. Spore density treatments consisted of 0, 5000, 10 000, 15 000, 20 000, 25 000, or 30 000 spore/mL applied either in the morning or in the afternoon. The results showed that the higher the spore density, the higher the number of pustules formed, the higher the disese intensity, and the faster the disease progressed. Urediniospores applied in the afternoon produced more pustules, higher disease intensity, and faster disease progression compare to those applied in the morning.
