            摘要: Abstract: Camelina (Camelina sativa) together with other oilseed crops have garnered interest as potential sources of biodiesel. Experiments were conducted in 2006 and 2007 to determine herbicide tolerance of camelina. Two rates of eight preemergence (PRE) and ten postemergence (POST) herbicides were applied to camelina. PRE herbicides evaluated included: acetochlor, trifluralin, ethalfluralin, pendimethalin, triallate, metolachlor, sulfentrazone, and EPTC. POST herbicides evaluated included: fluroxypyr, bromoxynil, clopyralid, MCPA, 2,4-DB, bentazon, clethodim, sethoxydim, thifensulfuron, and tribenuron. PRE herbicides were applied prior to planting and POST herbicides were applied on 6 to 10 inch tall camelina plants. Camelina was seeded at 3 lb/A and treatments were replicated four times. The entire experiment was conducted weed-free in order to focus on herbicide tolerance. Treatments were compared to two nontreated controls. PRE herbicide injury typically was evident as stand reduction, while POST herbicide injury was recognizable as stunting/chlorosis. In both years at 6 weeks after preemergence treatment, stand reduction was less than 6% when trifluralin, ethalfluralin, pendimethalin, and triallate were applied at the full rate. Sulfentrazone completely eliminated camelina from treated plots regardless of rate. The other PRE herbicides reduced camelina stand 15 to 56% at the half rate and 17 to 70% at the full rate. In 2006, camelina seed yield, with the exception of sulfentrazone, did not differ from the nontreated controls regardless of rate. This result occurred because plants in plots treated with PRE herbicides that did survive became larger and produced more seed per plant compared to plants treated with herbicides that did not cause stand reduction. In 2007, camelina yield from plots treated with trifluralin, ethalfluralin, and pendimethalin were higher than yield from plots treated with acetochlor or triallate. In both years, stunting/chlorosis caused by applications of clopyralid, 2,4-DB, clethodim, and sethoxydim at 6 weeks after postemergence treatment was less than 6%. In both years, applications of either rate of thifensulfuron or tribenuron controlled camelina greater than 70%. Applications of MCPA controlled camelina from 56% with the half rate to 84% with the full rate. The other POST herbicides controlled camelina 8 to 40% at the low rates and 18 to 73% at the high rates. In both years, camelina in plots treated with clethodim, sethoxydim, and the low rate of bromoxynil produced yields equivalent to the nontreated controls. Plants in plots treated with clopyralid were essentially sterilized and did not produce seed. Results indicate that there are several herbicides that have the potential to be utilized in camelina for weed control, however additional research needs to be conducted to confirm these results.
