Technical Abstract: Field studies were conducted to determine the efficiency and crop safety of trifluralin, [2,6-dinitro-N, N-dipropyl-4-(trifluoromethyl) benzenamine], in coriander (Coriandrum sativum, L.), dill (Anethum graveolens, L.), and dandelion greens (Taraxacum officinale, Weber) when applied pre-plant incorporated at 0.56 and 0.84 kg ai/ha. Visual injury evaluations, crop fresh and dry weight at maturity, and leaf area were used to determine adverse affects of trifluralin on each crop when compared to an untreated control. Dandelion greens had a 47 and 49% reduction in leaf area when treated with trifluralin at 0.56 and 0.84 kg ai/ha when compared to the untreated weed free dandelion treatment. Coriander and dill showed no visual crop phytotoxicity and no adverse affects on crop growth, fresh and dry weight yield, or leaf area when treated with trifluralin. Trifluralin, when used in combination with early season mechanical cultivation, can provide selective weed control of many of the most common winter annual weeds in south Texas while exhibiting a high level of crop tolerance for coriander and dill.
