Life cycle of Puccinia acroptili on Rhaponticum (= Acroptilon) repens.
Russian knapweed (Rhaponticum repens) is a rangeland weed pest in the western United States. One candidate fungus for biological control of R. repens is Puccinia acroptili, which causes a rust disease. Understanding the life cycle of candidate rust fungi for weed biological control is an essential component in risk assessments and evaluations, and for P. acroptili such was unknown. For this rea...

چکیده گیاه تلخه (Acroptilon repens L.) علف هرزی چندساله وسمج از تیره کاسنی است که سبب بروز مشکلات فراوانی در مزارع، باغات، مراتع وچراگاه ها در ایران و اکثر مناطق جهان می شود. به منظور بررسی امکان کنترل بیولوژیکی تلخه به وسیلهعوامل بیماری زای قارچی، پژوهشی در مناطق مختلف شهرستان چناران و مشهد در سال 1390-1391 صورت گرفت. ابتدا عوامل بیماری زا از روی تلخه جمع آوری و در محیط های کشت آزمایشگاهی خالص...
متن کاملRevegetating Russian Knapweed (Acroptilon repens) and Green Rabbitbrush (Ericameria teretifolia) Infested Rangeland in a Single Entry
The objective of this study was to test the potential for using a single-entry procedure to revegetate Russian knapweed– and green rabbitbrush–infested rangeland. I hypothesized that simultaneously applying an herbicide and seeding in the fall would produce the highest establishment and growth of desired species. For Russian knapweed, treatments included three seeding rates (zero, low, and high...
متن کاملTorpedograss (Panicum repens L.)

It is also known as quack grass and bullet grass. When fully matured, torpedograss can grow up to 3 feet tall and form dense monotypic stands that out compete native species and lead to a loss of diversity and overall ecological heal...
متن کاملMass Culture of Subanguina picridis and Its Bioherbicidal Efficacy on Acroptilon repens.
A Russian knapweed (Acroptilon repens) shoot culture system, initiated from shoot tip culture, was used to generate a source of host plant tissue for the rearing of the nematode Subanguina picridis, a biocontrol agent for Russian knapweed. Young shoots growing on solid B5G medium in petri dishes developed galls on leaves, petioles, and shoot tips 7 days after release of 50 nematodes onto the su...
