Management Options and Factors Affecting Control of a Common Waterhemp (Amaranthus rudis) Biotype Resistant to Protoporphyrinogen Oxidase-Inhibiting Herbicides

, 2020
Repeated use of protox-inhibiting herbicides has resulted in a common waterhemp (Amaranthus rudis Sauer) biotype that survived lactofen applied up to 10 times the labeled rate.

Changing landscape of waterhemp herbicide resistance in Wisconsin: a comparative analysis over time

Weed Technology
A comprehensive assessment of herbicide resistance in waterhemp accessions to herbicides commonly used on corn and soybean over time is crucially necessary for documenting shifts in herbicide resistance patterns and identifying effective management ...

Interaction of Pyroxasulfone and Encapsulated Saflufenacil Applied Preemergence for Control of Waterhemp in Corn

Journal of Agricultural Science
Waterhemp is a problematic weed in corn production that is rapidly evolving multiple herbicide resistance; 5-way resistance to herbicide groups 2, 5, 9, 14 and 27 has been confirmed in multiple counties across southern Ontario. The introduction of a new premix herbicide, pyroxasulfone plus encapsulated saflufenacil, provides growers with an additional ...

Mechanisms and control of waterhemp populations resistant to group 15 herbicides [PDF]

, 2021
Herbicides that inhibit very long-chain fatty acids (VLCFAs) have been applied for preemergence (PRE) control of annual grasses and small-seed broadleaf weeds for over sixty years.

Waterhemp breaking through soybean canopy [PDF]

, 2016
The past week I received several calls concerning waterhemp that was just beginning to break through the soybean canopy. The callers were wondering whether it is worth making another application for these weeds; the answer is "no." They also wanted to ...

Influence of saflufenacil encapsulation on corn phytotoxicity and residual broadleaf weed control

Weed Technology
Saflufenacil, a herbicide that inhibits protoporphyrinogen oxidase, has been reformulated as a microencapsulation for preemergence and postemergence applications to corn, with the primary purpose of the encapsulation to reduce the risk of corn injury ...
