Abstract

Small burnet is a relatively unknown plant that is commonly used in North America. It is a hardy, relatively long lived forb native to Eurasia that grows well in most of North America. It is considered to be excellent forage for livestock and wildlife and because of its evergreen nature there is interest in its use to extend grazing of pastures and rangelands into late fall and winter.

Popular sources reference its use in salads, ice drinks, with cream cheese, as a desirable garnish due to its distinct cucumber aroma and flavor. It is also reported to be a superb wildlife attractant for game hunters.

There is limited literature available on seed production and general care of small burnet. This study was conducted to assist the small burnet seed producer and possibly the range/landowner who has small burnet in their pastures or range. Results from this study show that there are a number of herbicides that small burnet can tolerate. These herbicides include clethodim, metribuzin, quinclorac, clopyralid, dimethenamid-P, bromoxynil, and pendimethalin, which may cause some initial injury to small burnet but the small burnet recovers from the injury. Data suggests that aminopyralid and imazamox should not be used for weed control in small burnet.
