Climatic Constraints to the Potential of Microsphaeropsis amaranthi as a Bioherbicide for Common Waterhemp [PDF]
The fungal plant pathogen Microsphaeropsis amaranthi is a candidate bioherbicide for the control of weedy Amaranthus species since it grows and sporulates readily in culture, is a pathogen of a number of important weed species, and is host-restricted to the family Amaranthaceae.

Performance of Two Bioherbicide Fungi for Waterhemp and Pigweed Control in Pumpkin and Soybean [PDF]
Common waterhemp (Amaranthus rudis) and pigweeds (Amaranthus spp.) are troublesome weeds in many cropping systems and have evolved resistance to several herbicides. Field trials to further develop Microsphaeropsis amaranthi and Phomopsis amaranthicola as bioherbicides for control of waterhemp and pigweeds were conducted to test the effectiveness of ...

Multiple herbicide-resistant waterhemp control with Group 15 herbicides
AbstractWaterhemp has evolved resistance to seven herbicide modes of action in the United States and to five in Canada, which limits weed control options for producers. The objective of this research was to quantify the level and duration of residual control of multiple herbicide-resistant (MHR) waterhemp with five Group 15 herbicides (acetochlor ...

Distinct Detoxification Mechanisms Confer Resistance to Mesotrione and Atrazine in a Population of Waterhemp [PDF]
Abstract Previous research reported the first case of resistance to mesotrione and other 4-hydroxyphenylpyruvate dioxygenase (HPPD) herbicides in a waterhemp (Amaranthus tuberculatus) population designated MCR (for McLean County mesotrione- and atrazine-resistant).

Evaluation of Acetochlor for Control of Multiple-Herbicide-Resistant Waterhemp (Amaranthus tuberculatus (Moq.) J.D. Sauer) in Ontario Crops [PDF]
Twenty-five field trials were conducted in 2021 and 2022 to evaluate multiple-herbicide-resistant waterhemp control with acetochlor. Phaseolus vulgaris dry beans, corn, and soybean were tolerant to acetochlor; tank mixing acetochlor and flumioxazin ...

Herbicide Programs for Waterhemp Control in Soybean [PDF]
Waterhemp is a dioecious (male and female flowers on separate plants) pigweed with a high genetic diversity. Consequently, this pigweed has a high propensity to adapt to control tactics and has evolved resistance to herbicides from as many as 6 or 7 ...

Gene Duplication and Aneuploidy Trigger Rapid Evolution of Herbicide Resistance in Common Waterhemp [PDF]
An increase in gene copy number is often associated with changes in the number and structure of chromosomes, as has been widely observed in yeast and eukaryotic tumors, yet little is known about stress-induced chromosomal changes in plants. Previously, we reported that the EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) gene, the molecular target ...
