“…Creeping thistle (Cirsium Arvensis (L.) Scop.) is an invasive weed species which is one of the biggest threats to the sugar beet as 5-6 plants/m 2 can halve the crop yield (Miller et al, 1994). Treating thistles requires huge quantities of herbicides because it is becoming increasingly frequent (Andreasen and Stryhn, 2012).…”

“…Yield loss due to Canada thistle competition has been evaluated in many crops including alfalfa grown for hay (Schreiber 1967), barley (Hordeum vulgare L.) (O'Sullivan et al 1982), winter and spring wheat (Triticum aestivum L.) (Donald and Khan 1992;McLennan et al 1991), oats (Avena sativa L.) (Hodgson 1955), and sugarbeet (Beta vulgaris L.) (Miller et al 1994). Behrens and Elakkad (1981) speculated that Canada thistle causes greater yield losses than any other perennial broadleaf weed.…”

Canada Thistle (Cirsium arvense) Control in Established Alfalfa (Medicago sativa) Grown for Seed Production¹

Canada thistle is one of the most troublesome and difficult weed species to control in established alfalfa grown for seed production. Current tools available for control are limited because of cultural management strategies associated with seed production. Alfalfa seed losses due to Canada thistle interference include both reduced yields from competition and increased seed loss during seed cleaning operations. Additional tools are needed to alleviate these losses. Field experiments were conducted in 1998, 1999, and 2000 at two locations in Park County, WY, to evaluate Canada thistle control and alfalfa tolerance to several postemergence herbicides. Bentazon, imazamox, imazethapyr, and MCPB were applied, alone or in combination, at different Canada thistle growth stages. Methylated seed oil (MSO) was added at 1.5% v/v to the treatments containing imazamox or imazethapyr. MCPB applied alone when Canada thistle was 7.5- or 15-cm tall caused severe alfalfa injury (28 to 40%) and resulted in less Canada thistle control (23 to 27%). Imazamox or imazethapyr applied alone when Canada thistle was 15-cm tall did not cause any significant alfalfa injury but resulted in unsatisfactory Canada thistle control (29 to 35%). Bentazon was the only treatment containing a single herbicide that provided more than 50% Canada thistle control. The treatments providing the best balance between Canada thistle control (>80%) and alfalfa injury (<13%) were a single application of bentazon combined with either imazamox or imazethapyr. These two treatments also yielded the highest, more than 800 kg/ha. Split applications of bentazon combined with imazamox or imazethapyr were similar to single applications.

Thistles of Greece and their potential value as Medicinal Crops: Study on their First Growth

Canadian thistle (Cirsium arvense (L.) Scop.), Milk thistle (Silybum marianum (L.) Gaertn.) and Scotch thistle (Onopordum acanthium L.) are weed species, which can be also useful medicinal plants. A preliminary seed germination test was conducted, while a greenhouse experiment was also established during 2015 at the Agricultural University of Athens, where seed germination, seedling emergence, first growth rate and biomass production of three biotypes of S. marianum, two biotypes of C. arvense and three biotypes of O. acanthium were evaluated. According to the results of this study, seed germination and seedling emergence were high for all species and biotypes. First growth rate and earliness were significant different between the several species. High biomass production was found in the biotypes originated from arable fields. In conclusion, this research work proved that there is a potential of exploitation of thistles according to their many uses. Seed germination, seedling emergence, first growth, biomass production and earliness of some biotypes seem rather satisfactory, while the high genetic variability of these three weeds can be used as a source for any future breeding attempts.
