Low carryover risk of late-season soybean herbicides to newly planted sugarcane

Weed Technology
Numerous annual and perennial weeds infest sugarcane. End-season weed infestations are managed before sugarcane is replanted by fallowing (cultivation and sequential glyphosate applications) or by rotating to glyphosate-tolerant soybean in Louisiana ...

Analytical methods for the determination of acifluorfen and bentazone residues in crops

Journal of Food and Drug Analysis, 2020
Methods using high performance liquid chromatography (HPLC) were developed to determine acifluorfen and bentazone in crops. Twenty samples of dry bean crops and rice were purchased from traditional markets and analyzed. Acifluorfen and bentazone being weak acids, were selectively extracted as ion pair compounds formed with tetrabutylammonium ion into ...

Implications of cereal rye cover crop termination timing and residue management on Palmer amaranth (Amaranthus palmeri) and sicklepod (Senna obtusifolia) control in peanut

Weed Technology
Weed management in peanut primarily relies on intensive herbicide programs. Integrating cereal rye as a cover crop may reduce herbicide input without compromising weed control.

Response of stevia to herbicides applied post-transplant in the greenhouse

Weed Technology
Greenhouse studies were conducted to determine the response of stevia to several herbicide modes of action applied 2 wk after transplanting. At 1 wk after treatment (WAT), stevia was injured 34% to 39% by aciflourfen, metribuzin, and carfentrazone.
