Seed germination of Bidens subalternans DC. exposed to different environmental factors. [PDF]

PLoS ONE, 2020
Bidens subalternans DC. is a weed found in several tropical countries such as Brazil. Large number of produced seeds and easy dispersion favor the colonization of agricultural fields by this species.

EFFECTIVENESS OF TERBUTHYLAZINE AND ATRAZINE IN THE CONTROL OF Bidens subalternans IN THREE STAGES OF APPLICATION [PDF]

Nativa
The objective was to evaluate the efficacy of terbuthylazine and atrazine doses in controlling greater beggarticks (Bidens subalternans) that are resistant to ALS inhibitors and exhibit resistance to atrazine, at three application times. The treatments were arranged in a 2x6 factorial design, in which two herbicides were used: atrazine and ...
