Enhancing incidence of Puccinia punctiformis, through mowing, to improve management of Canada thistle (Cirsium arvense)
Biological control of Canada thistle using Puccinia punctiformis has been largely unsuccessful in part due to a low incidence of systemically infected shoots and heterogeneous distribution of teliospores in the soil. The present study investigated the feasibility of strategic mowing to improve incidence of systemically infected shoots, and enhance intraand/or inter-season disease development in...
متن کاملAbsorption and Translocation of Aminocyclopyrachlor and Aminocyclopyrachlor-Methyl Ester in Canada Thistle (Cirsium arvense)
Laboratory studies were conducted using C-aminocyclopyrachlor (DPX-MAT28) and its C-methyl ester formulation (DPX-KJM44) to (1) determine the adjuvants’ effects on absorption, (2) compare the absorption and translocation of aminocyclopyrachlor free acid with the methyl ester, and (3) determine the rate at which aminocyclopyrachlor-methyl ester is metabolized to the free acid in Canada thistle. ...
متن کاملProduction and Wind Dispersal of Canada Thistle (Cirsium arvense L.) Achenes
Quantity, quality and dispersal distance of wind-blown achenes and pappi were determined during the peak time of dispersal over twelve site-years in Minnesota during 2006 and 2007. Approximately twice as many pappi than achenes were trapped. Wind blown pappi tend to travel near the ground. Most achenes fell near the parent plants and their population density declined exponentially with increasi...
متن کاملCanola in Rotations
• Canola is one of the most profitable crops available to grain growers in southern and western Australia and rotations have been adapted to accommodate it. • Canola provides large yield benefits to subsequent cereal crops by providing an effective disease break. • Canola was often grown as the first crop after pasture but now canola is often used more intensively in rotations, posing problems ...
متن کاملEstablishing systemic rust infections in Cirsium arvense in the field
An existing method to induce systemic rust infections in creeping thistles (Cirsium arvense) using an insect vector, the weevil Ceratapion onopordi, was successfully applied in the field. Urediniospores of Puccinia punctiformis were experimentally transmitted to naturally grown thistles, to our knowledge for the first time resulting in systemically infected shoots in an established thistle popu...
