The species spreads by creeping roots which in turn causes Canada thistle to … The stalks, however, are also edible and more easily despined. Canada thistle is native to Europe. The compounds found in the fragrance may not be in the highest abundance but they are highly attractive. After pollination, it can be seen that fragrance emission decreases in C.arvense. Canada thistle (Cirsium arvense) is a root-creeping perennial. Although some insects feed on foliage, stems, crowns, and developing seeds, control is often highly variable. Legal status: Canada thistle is considered a noxious weed in 46 states including Indiana. Many herbicides registered in fruit crops may burn back the top growth of the weed, but do very little to suppress the extensive root system. Scientific name: Cirsium arvense (L.) Scop.

[32] It is also a serious invasive species in many additional regions where it has been introduced, usually accidentally as a contaminant in cereal crop seeds. High antennal response are seen in consequence to the phenylacetaldehyde as well as the terpenes (oxoisophoroneoxide, oxoisophorone, and dihydrooxoisophorone) found in the blend. Thickets of thistle crowd out forage grasses in pastures and rangelands, reducing crop yields and productivity. Control Canada thistle in roadsides, field roads, and fencerows. [39] It may therefore not be a desirable control agent. [31], The species is widely considered a weed even where it is native, for example being designated an "injurious weed" in the United Kingdom under the Weeds Act 1959. Differences can be seen in their R-protein mediated defenses, sensitivities to abiotic stresses and developmental timing. Repeated cutting at the same growth stage over several years may "wear down" the plant.

Depending on the fruit crop grown, cool-season crops like cereal rye can be planted in row middles in the late summer/early fall and will compete with Canada thistle as it emerges in spring. Aceria anthocoptes feeds on this species and is considered to be a good potential biological control agent. Canada thistle (note that it's NOT 'Canadian' thistle) is in the family Asteraceae. Life Cycle. Many countries regulate this plant, or its parts (i.e., seed) as a contaminant of other imported products such as grains for consumption or seeds for propagation.

[15], GIven its adaptive nature, Cirsium arvense is one of the worst invasive weeds worldwide. Through comparison of its genetic expressions, the plant evolves differently with respects to where it has established itself.
