Increasing the efficiency of food production systems while reducing negative environmental effects remains a key societal challenge to successfully meet needs growing global population. The herbicide glyphosate has become nearly ubiquitous component agricultural across globe, enabling an increasing adoption no-till agriculture. Despite this widespread use, there considerable debate on consequences exposure. In paper, we examine effect soil microbial communities associated with roots...
Reduction of seed-bank persistence is an important goal for weed management systems. Recent interest in more biological-based strategies has led to closer examination the role soil microorganisms. Incidences seed decay with certain species occur laboratory; however, their indicates presence yet-unknown factors natural systems that regulate biological mechanisms antagonism by A fundamental understanding interactions between seeds and microorganisms will have implications future targeting...
Abstract The advent of modern technologies, acquisition large amounts crop management and weather data, advances in computing are reshaping agriculture. These advancements have unlocked the power data by providing valuable insights more accurate yield predictions. This study utilizes a historic US sweet corn dataset to: (a) evaluate machine learning model performances on prediction (b) identify most influential variables for comprised field-level over quarter-century period (1992–2018) from...
Abstract The opportunity to increase soybean yield has prompted Illinois farmers plant earlier than historical norms. Extending the growing season with an planting date might alter relationship between growth and weed emergence timings, potentially altering optimal herbicide application timings minimize crop loss due interference ensure minimal seed production. objective of this research was examine various treatments applied at different rates assess effect on control in early planted...
Agronomic and weed management practices employed by growers in the production of snap bean ( Phaseolus vulgaris ) for processing industry are poorly characterized. To address this knowledge gap, records agronomic from 358 fields were obtained collaborating processors. These encompassed three regions United States: Northwest (NW), Midwest (MW), Northeast (NE). The formatted to be more suitable presentation or analysis. Forty cultivars used across all regions, primarily green round podded type...
Cover crop residues are not widely used for weed control because, as a stand-alone tactic, they do effectively suppress all weeds and their duration of is too short. Field experiments were conducted in 1995 1996, under both irrigated rainfed conditions, to quantify Amaranthus spp., Setaria soybean emergence growth fall-planted, spring-killed barley, rye, triticale, wheat, hairy vetch. For species, seedling was reduced 3 wk after planting by rye wheat (≥ 2, 170 kg ha −1 ) 1996. In spp. canopy...
ABSTRACT In this paper, we first develop a measure of total factor productivity (TFP) growth and summarize source‐of‐growth analysis for the manufacturing sector 48 states. As have others, find little association between TFP differentials output census regions. At staterather than regional level, however, positive growth. We use cross‐sectional data to estimate determinants variation in Two results emerge that are important policy understanding national trends. First, state investments...
The critical period for weed control (CPWC) identifies the phase of crop growth cycle when interference results in unacceptable yield losses; however, effect planting date on CPWC is not well understood. Field studies were conducted 2004 and 2005 at Urbana, IL, to determine sweet corn early May (EARLY) late-June (LATE) dates. A quantitative series treatments both increasing duration length weed-free imposed within each planting-date main plot. beginning end CPWC, based 5% loss marketable ear...

Weed seedbanks have been studied intensively at local scales, but to date, there no regional-scale studies of weed seedbank persistence. Empirical and modeling indicate that reducing persistence can play an important role in integrated management. Annual 13 summer annual species was from 2001 through 2003 eight locations the north central United States one location northwestern States. Effects seed depth placement, tillage, abiotic environmental factors on were examined regression...
Abstract The herbicides that inhibit 4-hydroxyphenylpyruvate dioxygenase (HPPD) are primarily used for weed control in corn, barley, oat, rice, sorghum, sugarcane, and wheat production fields the United States. objectives of this review were to summarize 1) history HPPD-inhibitor their use States; 2) resistant weeds, mechanism resistance, management; 3) interaction with other herbicides; 4) future HPPD-inhibitor-resistant crops. As 2022, three broadleaf weeds (Palmer amaranth, waterhemp,...
Summary Although foreign direct investment into developed economies continues to show dramatic growth, little consensus exists over either its national or regional impacts. The lack of empirical evidence, particularly on a sub‐national level, adds the uncertainty efficacy development strategies focused attracting investment. present research uses book value and employment measures U.S. state‐level FDI activity assess impact capital growth productivity performance. results imply vital role...
Nicosulfuron, mesotrione, dicamba plus diflufenzopyr, and carfentrazone are postemergence herbicides from different chemical families with modes of action. An association between the sensitivity sweet corn to these was observed when 143 F 3 : 4 (F plants) derived a cross Cr1 (sensitive inbred) Cr2 (tolerant were evaluated in greenhouse trials. The ratio tolerant segregating sensitive not significantly 2 ratio, which would be expected if single gene conditioned herbicide response. Families...
Abstract BACKGROUND There has been controversy as to whether the glyphosate resistance gene and/or applied glyphosate‐resistant (GR) soybean affect content of cationic minerals (especially Mg, Mn and Fe), yield amino acid GR soybean. A two‐year field study (2013 2014) examined these questions at sites in Mississippi, USA. RESULTS were no effects glyphosate, transgene or crop history (for a with both use versus one long use) on grain yield. Furthermore, factors had consistent measured mineral...
As weather patterns become more volatile and extreme, risks introduced by variability will critical to agricultural production. The availability of days suitable for field work is driven soil temperature moisture, both which may be altered climate change. We projected changes in Illinois season length, spring workability, summer drought risk under three different emissions scenarios (B1, A1B, A2) down the crop district scale. Across all scenarios, thermal time units increased parallel with a...
Summary Transdisciplinary weed research ( TWR ) is a promising path to more effective management of challenging problems. We define as an integrated process inquiry and action that addresses complex problems in the context broader efforts improve economic, environmental social aspects ecosystem sustainability. seeks integrate scholarly practical knowledge across many stakeholder groups (e.g. scientists, private sector, farmers extension officers) levels local, regional landscape)....
Abstract BACKGROUND Nicosulfuron, a sulfonylurea herbicide widely used for grass weed control in corn production, injures some sweet hybrids and inbreds. A specific cytochrome P450 (P450), CYP81A9, is suggested to be responsible sensitivity nicosulfuron other P450‐metabolized herbicides. Corn CYP81A9 enzymes were expressed E. coli investigated find the factor(s) associated with their function variation metabolizing nicosulfuron. RESULT Recombinant CYP81A9s from tolerant inbreds produced an...
Both weed interference and adverse weather can cause significant maize yield losses. However, most climate change projections on yields ignore the fact that weeds are widespread in production. Herein, we examine effects of control variability loss due to by using machine learning techniques an expansive database herbicide efficacy trials spanning 205 environments 27 years. Late-season all species was important driver according multiple analyses. Average losses 50% were observed with little...
Since the 1950's much of US soybean growing region has experienced rising temperatures, more variable rainfall, and increased carbon emissions. These trends are predicted to continue throughout 21st century. Variable weather weed interference influence crop performance; however, their combined effects on yield poorly understood. Using machine learning techniques a database herbicide trials spanning 28 years 106 environments we modeled most important relationships among control, variability,...
