Performance of Preemergence Herbicides on Waterhemp Control in Soybean [PDF]

open access: yes, 2020
The battle against waterhemp is complicated mainly because of its extended emergence period (early May until August). Preemergence (PRE) soil residual herbicides serve as a foundation for managing waterhemp, but require follow-up treatments with ...

Characterizing geographic diversity of acetolactate synthase resistance in US johnsongrass (Sorghum halepense) biotypes

open access: yesPest Management Science, EarlyView.
Geographical distribution of screened Sorghum halepense biotypes across the USA illustrating variation in nicosulfuron response driven by associated ALS resistance‐allele frequencies among representative biotypes. Abstract BACKGROUND Acetolactate synthase (ALS)‐inhibiting herbicides are widely used for Sorghum halepense weed control across ...

First Record of Larval Parasitism in Disonycha glabrata (F.) (Coleoptera: Chrysomelidae) by Myiopharus ancilla (Walker) (Diptera: Tachinidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The amaranth flea beetle, Disonycha glabrata (F.), is a major pest of amaranth crops (Amaranthus spp.) in the United States. Despite its economic impact, its natural enemy complex remains poorly documented. In this study, we report the first record of larval parasitism in D. glabrata by the tachinid fly Myiopharus ancilla (Walker).

Managing herbicide-resistant waterhemp (Amaranthus tuberculatus) in Midwestern United States soybean systems

open access: yes, 2023
Weed infestations, namely herbicide-resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) prevent growers from achieving optimal yields; therefore, growers are seeking tactics to reduce or prevent crop-weed competition.

Economic analysis of diversified corn herbicide programs for weed management and rotation flexibility in western Nebraska

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Corn (Zea mays L.), dry edible bean (Phaseolus vulgaris L.), and sugarbeet (Beta vulgaris L.) are frequently grown in rotation in the Panhandle of Nebraska. The primary weed challenges in this system are Palmer amaranth (Amaranthus palmeri S. Watson) and kochia [Bassia scoparia (L.) A.

Prediction of cereal rye biomass accumulation in Wisconsin based on weather and agronomic management

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Cereal rye (Secale cereale L.) biomass accumulation is strongly influenced by weather conditions and management practices, making accurate biomass estimates critical for guiding farmers’ management decisions. In this study, we evaluated how weather (e.g., temperature and rainfall) and management practices (including planting and termination ...

Factors leading to inconsistent waterhemp control [PDF]

open access: yes, 2015
Waterhemp continues to be one of the most problematic weeds for Iowa farmers. A higher frequency of waterhemp escapes was observed in Roundup Ready soybean fields during 2001 than in previous years.

Research Report: Prevalence and Mechanism of Atrazine Resistance in Waterhemp from Nebraska [PDF]

open access: yes, 2018
Waterhemp is a troublesome summer annual broadleaf weed species that has evolved resistance to glyphosate and other herbicide sites of action (SOA) in Nebraska, including to groups 2 (i.e., Classic, Pursuit, FirstRate), 4 (i.e., 2, 4-D), 5(i.e., atrazine)
