Extract

Smicronyx utilis is a small curculionid beetle which in Saskatchewan breeds in the seeds of Iva axillaris Pursh., or poverty weed. The weed is a native perennial found from the Saskatchewan-Manitoba border to British Columbia and south to Mexico. Although not as prevalent as some of the other bad weeds, it is one of the most persistent and one of the most difficult to eradicate. Owing to the fact that, in Saskatchewan, the percentage of infestation in well-developed seeds is very high, the plant appears to spread by rootstocks only. This facilitates eradication considerably.
