This book was released on 2018 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protoporphyrinogen oxidase (PPO)-inhibiting herbicides in combination with glyphosate for postemergence (POST) applications is one of the primary alternatives to manage glyphosate-resistant weeds and the only effective POST chemical option in conventional and glyphosate-tolerant soybean to control glyphosate and ALS-inhibiting resistant weeds. Antagonistic interactions have been reported between many different herbicide modes of action and optimal droplet size may be affected by tank-mixtures of different herbicides. Additionally, the impact of adjuvants on the factors aforementioned as well as on physical properties needs to be thoroughly investigate to maximize herbicide efficacy. Therefore, the objectives of this research were to: 1) conduct greenhouse and field studies to evaluate the impact of glyphosate and PPO-inhibiting herbicides (fomesafen or lactofen) applied alone and in tank mixtures on weed control, optimal droplet size, drift potential, and tank mixture interactions, 2) determine the influence of adjuvants on tank mixtures interactions, spray droplet-spectra, drift potential, and physical properties, (3) determine if herbicide efficacy (and thereby, weed control) is correlated to reduced surface tension and contact angle. Overall, applications from the tank mixtures resulted in antagonistic interactions and some of them were overcame by the addition of adjuvants. Droplet size and percent volume of droplets ≤ 150 μm were highly affected by nozzle type and spray solution. The oil based formulation of lactofen and crop oil concentrates were shattered by TTI nozzles due to its internal turbulence chamber creating smaller droplets and increasing driftable fines. The impact of nozzle selection on weed control was minimal and larger droplets at the rates and carrier volume used in this study could be used without compromising herbicide efficacy reducing drift potential. Adjuvants reduced the surface tension and contact angle of spray solutions; however, herbicide efficacy was only partially explained by the changes in these physical properties. Results emphasized the importance of better understanding the relationship among application variables and weed species. In addition, recommendations should be herbicide- and weed-specific in order to optimize herbicide applications and to maintain herbicide effectiveness.

Book excerpt: Field and greenhouse experiments were conducted in 2008, 2009, and 2010 to evaluate the efficacy of glyphosate combined with other broadleaf herbicides on herbicide-resistant and -susceptible weeds in Illinois. Although this research supports an improvement in control of glyphosate-resistant common waterhemp with the addition of PPO-inhibiting herbicides to glyphosate, the overall herbicide efficacy was still somewhat variable with evidence for environmental conditions that may alter efficacy of the tank mixtures. Thus, the use of preemergence, soil residual herbicides are still justified to reduce reliance on these postemergence herbicide mixtures for weed control in soybean and ultimately deter further selection of common waterhemp populations resistant to glyphosate and PPO-inhibiting herbicides.

This book was released on 2021 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: XtendFlex® soybean is a new trait platform which confers resistance to three herbicide sites of action that include the active ingredients dicamba, glyphosate, and glufosinate. The ability to use these three herbicides in one system has generated new management questions. Field and greenhouse experiments were conducted in 2019 and 2020 to: 1) investigate weed control systems in conventional and no-tillage XtendFlex® soybean, and 2) identify any antagonistic or synergistic responses from herbicide-tank mixtures used in this system. Control of glyphosate-resistant (GR) waterhemp was optimized with PRE flumioxazin followed by (fb) POST glufosinate or dicamba alone or in combination with each other or glyphosate. Two-pass POST systems also controlled GR waterhemp as long as dicamba and/or glufosinate was used in each application. GR horseweed control was exceptional with all herbicide programs evaluated, except glyphosate alone EPOS or POST. Annual grass control was reduced with EPOS and POST glufosinate + dicamba tank-mixtures. In contrast, this combination was often additive or synergistic for both broadleaf and grass weed control in the greenhouse. Several glyphosate + glufosinate combinations were antagonistic, especially with broadleaf weeds. Dicamba + glyphosate was often antagonistic in the greenhouse but was additive or synergistic for GR waterhemp and GR horseweed control in the field. Antagonisms were often observed when all three herbicides were applied together; however, not all antagonisms resulted in poor control. This research provides growers insight into management strategies for various agronomically important weeds in XtendFlex® soybean. .

This book was released on 2015-05-21 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glyphosate, known by many trade names, including Roundup, is a highly effective herbicide. Widespread glyphosate use for corn and soybean has led to glyphosate resistance, which is now documented in 14 weed species affecting U.S. cropland, and recent surveys suggest that acreage with glyphosate-resistant (GR) weeds is expanding. Data from USDA's Agricultural Resource Management Survey (ARMS), along with the Benchmark Study (conducted independently by plant scientists), are used to address several issues raised by the spread of GR weeds. Choices made by growers that could help manage glyphosate resistance include using glyphosate during fewer years, combining it with one or more alternative herbicides, and, most importantly, not applying glyphosate during consecutive growing seasons. As a result, managing glyphosate resistance is more cost effective than ignoring it, and after about 2 years, the cumulative impact of the returns received is higher when managing instead of ignoring resistance.

This book was released on 2013 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, glyphosate-resistant (GR) giant ragweed (Ambrosia trifida L.) has become an increasingly problematic weed of soybean production systems in Missouri and throughout the Midwest. As of 2013, giant ragweed has been confirmed with resistance to glyphosate in 11 states and one Canadian province. The objectives of this research were to determine the effect of herbicide application timing and glyphosate tank-mix combinations on the survival of GR giant ragweed and the influence of pre-plant (PREPLT) followed by (fb) 2-pass post-emergence (POST) herbicide programs in GR and glufosinate-resistant soybean on GR giant ragweed density, soybean yield, and net economic return. Results from this research indicate that POST applications to smaller plants can reduce the survival of giant ragweed compared to applications to larger plants. For a POST only management strategy, fomesafen plus glyphosate applied to 10-cm plants fb glyphosate late post-emergence (LPOST) resulted in 37% survival and was the lowest survival observed. Overall, giant ragweed was nearly eliminated with PREPLT fb 2-pass POST programs. For example, no more than 6 plants 5-m-2 were observed if PREPLT applications contained an effective tank-mix combination in either soybean system. However, 244 plants 5-m-2 were observed following a program that consisted of glyphosate PREPLT fb glyphosate plus fomesafen early post-emergence (EPOST) fb glyphosate LPOST. Few differences in yield or net return were observed in the PREPLT experiments. However, programs that contained an effective PREPLT application generally resulted in higher yield and net economic return. Results from this research indicate that PREPLT applications can provide more effective control of giant ragweed compared to POST-only programs.

This book was released on 2014 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Common waterhemp (Amaranthus rudis Sauer) is the most prominent and troublesome weed in agronomic crops in Missouri, Iowa, and Illinois. As of 2014 in the U.S., herbicide resistance was present in waterhemp to one or more of the following herbicide modes of action: growth regulators, EPSPS-, acetolactate synthase (ALS)-, protoporphyrinogen (PPO)-, photosystem II (PSII)-, and 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicides. The objectives of this research were 1) determine the effect of cultural and herbicidal control methods on resistant waterhemp in glufosinate-resistant soybean, 2) evaluate weed management programs and response of HPPD-resistant soybean to HPPD-inhibiting herbicides, and 3) investigate the distribution of herbicide resistances and molecular mechanisms conferring resistance in Missouri waterhemp populations. Results from this research indicate that preemergence followed by postemergence with residual (PRE fb POST w/RES) herbicide programs with 19- or 38-cm rows will provide the greatest glyphosate-resistant (GR) waterhemp control in glufosinate resistant soybean. PRE fb POST programs improved GR waterhemp control and biomass reduction over all one- and two-pass POST programs in HPPD-resistant soybean. The addition of isoxaflutole to PRE treatments in HPPD- resistant soybean was not always necessary to provide high levels of weed control, but incorporating isoxaflutole or mesotrione in PRE fb POST programs allows for a greater diversity of effective herbicide modes of action. Resistance to five major herbicide modes of action was confirmed with at least 52% of 187 waterhemp populations being resistant to two modes of action. Results indicate PRE fb POST programs with multiple, effective modes of action will be necessary to control Missouri waterhemp populations in the future.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated weed management and herbicide application practices were assessed in field and greenhouse studies to improve weed control in herbicide-resistant soybeans (Glycine max (L.) Merr.) grown in Kansas. The field study was conducted to evaluate weed control, soybean yield, and profitability in two herbicide-resistant soybean systems and two row spacings. 2,4-D-, glyphosate-, and glufosinate- resistant (Enlist E3) and isoxaflutole-, glyphosate-, and glufosinate- resistant (LLGT27) soybeans were planted in 38- and 76-cm row spacing for four site-years. Three herbicide treatments were evaluated in each system: pre-emergence herbicide only (PRE), PRE followed by early post-emergence (POST), and POST plus overlapping residual (POR). Weed control was evaluated every 2 weeks after PRE application through R7 soybean. Weed biomass was collected before POST applications and at R7 soybean. Soybean yield was recorded at harvest. Data were subjected to analysis of variance and means separation. In Ottawa during 2020, POST and POR treatments resulted in ≥ 99% control for all species four WAT, while PRE resulted in ≥ 84% control. Similarly, control at Ashland Bottoms was ≥ 90% for POST and POR treatments, while PRE resulted in 7% for isoxaflutole- 62% for 2,4-D-resistant soybeans. All treatments resulted in ≥ 95% control at Scandia in 2021. Row spacing had a minimal effect on weed control and mixed results for yield. In the greenhouse study, the objective was to determine the effect of herbicide combination, optimize carrier volume, and evaluate weed height on weed control. Co-applications of combinations of 2,4-D choline, glyphosate, and glufosinate were applied in carrier volumes of 93-, 140-, and 187- L ha−1to 5-, 10-, and 20-cm Palmer amaranth (Amaranthus palmeri S. Watson) and large crabgrass (Digitaria sanguinalis L.). Visual ratings and above ground biomass were collected four weeks after treatment. Water-sensitive paper was also sprayed with the same herbicide combinations and carrier volumes to evaluate differences in spray coverage. Data were subjected to analysis of variance and means separation. Carrier volume did not affect Palmer amaranth or large crabgrass control. Control of 5-, 10-, and 20-cm Palmer amaranth was 100%, ≥ 91%, and 6.7 to 79%, respectively, and variation was caused by the herbicide combinations. 2,4-D plus glyphosate provided the greatest Palmer amaranth control. Large crabgrass control pooled for both experiments was ≥ 82% when treatments were applied at 5 cm, but control of 10- or 20-cm large crabgrass was reduced to 51 to 56%. There was a carrier volume by herbicide co-application interaction for the number of droplets deposited and percent area covered on water-sensitive paper. Co-applications containing glufosinate had more droplets than those not containing glufosinate. 2,4-D plus glyphosate had the smallest percent area covered, compared to the other herbicide co-applications. Data from the field study confirms that two-pass herbicide programs are superior to PRE- only programs, regardless of the inclusion of a layered residual herbicide. However, this research did not evaluate the impact of layered residual herbicides on weed seed production, which is crucial for long-term weed management. Results from the greenhouse study suggest that under ideal conditions, carrier volume is less important than herbicide combination and weed size for control of Palmer amaranth and large crabgrass.

This book was released on 2015 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: New herbicide-resistant soybean traits will increase the number of herbicides that can be applied in soybean and change the technology currently used to make herbicide applications in soybean. Palmer amaranth (Amaranthus palmeri) remains one of the most difficult weeds to manage in soybean and thus is the primary focus of this research. Therefore, experiments were conducted to investigate Palmer amaranth temporal emergence, control of common Arkansas weeds with new soybean herbicide programs, and the effect of application technology on dicamba-containing tank mixtures. Palmer amaranth emergence exceeded 400 plants m-2 for tillage treatments in 2013 and 2014, and tillage events typically increased emergence compared to no-tillage. The addition of isoxaflutole and mesotrione (HPPD-inhibitors) to soybean herbicide programs PRE improved control more than dicamba or 2,4-D (synthetic auxins) PRE. Herbicide programs that included HPPD-inhibitors EPOST improved control of Palmer amaranth more than programs with synthetic auxins. However, synthetic auxins applied LPOST controlled Palmer amaranth better than HPPD-inhibitors LPOST. Herbicide programs that included synthetic auxins or HPPD-inhibitors improved control of pitted morningglory but did not improve control of prickly sida and barnyardgrass compared to current standard herbicide programs. Applicator-controlled variables such as nozzle selection, spray volume, and groundspeed did not affect the efficacy of many dicamba-containing tank mixtures investigated. However, a tank mixture of the products Roundup PowerMax + Engenia produced an antagonistic effect on large barnyardgrass. Additionally, Palmer amaranth and barnyardgrass control was higher at 187 L ha-1 for Engenia + Roundup for the TTI nozzle than at 94 L ha-1. These results show that new technologies will improve control of some weeds in soybean, but the new technologies need to be applied using effective spray nozzles and spray volumes.

This book was released on 2013 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Johnsongrass, once the most persistent and troublesome grass weed of row crops throughout the southern U.S., has previously been confirmed resistant to the acetolactate synthase (ALS) and acetyl-coenzyme A carboxylase-inhibiting herbicides in the Midsouth and has recently evolved resistance to glyphosate in Arkansas. The goal of this research was to establish the geographical distribution of herbicide-resistant johnsongrass in Arkansas and to develop herbicide programs for controlling glyphosate-resistant johnsongrass in Arkansas soybean. Johnsongrass accessions were collected from 14 counties in the Mississippi River Delta region of Arkansas and screened for resistance to four of the most commonly used postemergence herbicides for johnsongrass control. One accession with reduced sensitivity to glyphosate and another with increased tolerance to imazethapyr were further evaluated in a rate titration experiment. The lethal dose required to kill 50% of the plants from the putative glyphosate-resistant and ALS-resistant accessions was higher than that of a known susceptible biotype. In the field, a single application of glufosinate alone failed to provide season-long johnsongrass control (≤67%); however, addition of another mode of action to glufosinate did result in effective johnsongrass control throughout the growing season. Herbicide programs were developed that effectively controlled glyphosate-resistant johnsongrass in both glyphosate- and glufosinate-resistant soybean. Late-season, salvage treatments were also established for reducing seed production in an effort to prevent the spread of glyphosate-resistant johnsongrass and mitigate the evolution of additional herbicide-resistant johnsongrass biotypes. When applied at the boot stage, late-season applications of clethodim, glufosinate, and glyphosate decreased viable seed production of a glyphosate-susceptible population.
