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...

15 صفحه اولEffect of Salicylic Acid on Antioxidant Activity in Milk Thistle Hairy Root Cultures
Background: Elicitors can trigger defense responses and activate specific genes involved in secondary metabolite biosynthesis. Objective: For understanding SA-treatment signaling pathway we determined defense-related compounds and enzymes in S. marianum hairy root cultures. Methods: 28 day old hairy roots were treated by salicylic acid (6 mg/50 ml culture) for different times (24, 48, 72, 96...
متن کاملEnhancing 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...
