Controlling Californian thistle (<i>Cirsium arvense</i>) through pasture management

Range and Pasture Management

Integrated Management Improves Canada Thistle Control

Canada thistle remains the most common and troublesome weed of pastures, roadsides and other areas of low-maintenance sods. Even though numerous herbicides have excellent activity on Canada thistle, the extensive root system of this species complicates longterm management. This paper will discuss recent research conducted in Alberta, Canada investigating the role of pasture fertilization in Can...

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...

Soil Nitrocxn and Pasture Management

The. seasonal pattern of nitrogen mineralization is described and compared with the potential demand for nitrogen by grasses. Peak mineralization rates occur in spring but are quite inadequate for expression of potential grass growth. Nitrogen fixation by clovers provides a significant input into the system over a short period. Consideration of the fate of fixed nitrogen shows that losses large...

Forage and Pasture Management for Laminitic Horses

In the past, many cases of laminitis have been of mysterious origin. Recent investigations in veterinary medicine, coupled with the availability of new techniques for analyzing hydrolyzable carbohydrates in forage may provide evidence to solve some of these mysteries. Fructan has been shown to be capable of inducing laminitis in clinical studies. Insulin resistance, a primary feature of Equine ...
