Ethephon Reduction of Redroot Pigweed (Amaranthus retroflexus) Seed Populations
Weed Technology, 1990Freshly collected redroot pigweed seeds were buried 5 cm deep in the field in November of 3 yr in succession. Treatments applied to the soil surface included KNO3(400 kg ha-1) in midwinter, ethephon (11 kg ha-1) in late spring, and a soil cover (polyethylene sheet for 2 wk) in late spring.

Multiple resistance to PPO and ALS inhibitors in redroot pigweed (Amaranthus retroflexus)
Weed Science, 2019Abstract A redroot pigweed (Amaranthus retroflexus L.) population (HN-02) collected from Nenjiang County, Heilongjiang Province, exhibited multiple resistance to fomesafen and nicosulfuron. The purposes of this study were to characterize the herbicide resistance status of an HN-02 population for both acetolactate synthase (ALS) and protoporphyrinogen

Redroot pigweed (Amaranthus retroflexus) poisoning of cattle in southern Brazil.
Veterinary and human toxicology, 1997Two outbreaks of Amaranthus retroflexus (redroot pigweed) poisoning occurring in cattle in southern Brazil in late summer and early autumn are described. In both instances too many cattle were held in small paddocks heavily invaded by A retroflexus in its seeding stage. In 1 herd 8/28 heifers and in the other 15/45 adult cows died.

Growth regulator effects of propiconazole on redroot pigweed (Amaranthus retroflexus)
Weed Technology, 2003Nonfungicidal effects of agricultural fungicides on crop plants have been reported previously; however, there are few reports of nontarget effects of fungicides on weedy species. Field research trials in Oregon demonstrated that the growth of several broadleaf weeds was reduced after multiple applications of the fungicide propiconazole.

Response of Corn and Redroot Pigweed to Nitrogen Fertilizer in Different Irrigation Regimes
Agronomy Journal, 2013The effect of irrigation regimes and N rates on corn (Zea mays L.) yield and redroot pigweed (Amaranthus retroflexus L.) growth in sandy soils is not completely understood. Therefore, field experiments were conducted in a semiarid region of Iran in 2010 and 2011 to determine the influence of N rates and irrigation regimes on corn and redroot pigweed ...
