Sweetpotato tolerance and Palmer amaranth control with indaziflam
Weed Technology, 2022 AbstractField studies were conducted in North Carolina in 2018 and 2019 to determine sweetpotato tolerance to indaziflam and its effectiveness in controlling Palmer amaranth in sweetpotato. Treatments included indaziflam pre-transplant; 7 d after transplanting (DATr) or 14 DATr at 29, 44, 58, or 73 g ai ha−1; and checks (weedy and weed-free ...

Confirmation of dicamba-resistant Palmer amaranth in Tennessee
Weed Technology, 2022 AbstractPalmer amaranth has a long history of evolving resistance to herbicides to the point at which it has become a significant obstacle to row crop production. A survey of Palmer amaranth escapes in dicamba-resistant cotton and soybean fields in Tennessee was conducted in fall 2021 with the objective of determining whether poor control was due to ...

Management Considerations for Palmer Amaranth in a Northern Great Plains Soybean Production System
Agrosystems, Geosciences & Environment, 2019 Core Ideas Soybean yield loss in South Dakota was dependent on Palmer amaranth density if it emerged before canopy closure. Soybean yield losses were not Palmer amaranth density dependent when it emerged at the R2 soybean growth stage.
