This Document Is the Property of Bayer AG And/Or Any of Its Affiliates. It January 2020 Safety Assessment of Dicamba and Glufosinate-Tolerant Cotton MON 88701 Monsanto Company has developed dicamba and glufosinate-tolerant cotton, MON 88701, which will allow over-the-top applications of dicamba herbicide for the control of broadleaf weeds from preemergence to seven days preharvest and glufosinate herbicide for broad spectrum weed control from emergence through early bloom growth stage. MON 88701 provides a wider dicamba window of application beyond the current preplant cotton uses and glufosinate application rates and timings that are equivalent to current commercial glufosinate-tolerant cotton. The combination of these two unique herbicide modes-of-action provides an effective weed management system for cotton production. Dicamba provides effective control of over 95 annual and biennial weed species, and suppression of and over 100 perennial broadleaf and woody plant species. Glufosinate, a broad-spectrum contactregime. herbicide, provides nonselective control of approximately 120 broadleaf and grass weeds. Additionally, dicamba and glufosinate provide control of herbicide-resistant weeds, including glyphosate-resistant biotypes of Palmer amaranth (Amaranthus palmeri), marestail (Conyza canadensis), common ragweed (Ambrosia publishing artemisiifolia), giant ragweed (Ambrosia trifida) and waterhemp and(Amaranthus protection tuberculatus ). MON 88701 contains a demethylase gene from Stenotrophomonas maltophilia that expresses a dicamba data mono-oxygenase (DMO) protein to confer tolerance to dicamba herbicide. DMOand/or proteincontents rapidly demethylates dicamba to the herbicidally inactive metaboliteproperty 3,6 -dichlorosalicylicits acid (DCSA). DCSA AG therefore has been previously identified as a metabolite of dicamba in cotton, soybean,or livestock, and soil.

MON 88701 was intensively tested in the laboratory and across multiple field sites in the USA. Data from those studies were used to conduct the product safety assessment and achieve government regulatory approvals. The product safety was based on the following: • A detailed molecular characterization of the inserted DNA demonstrated a single, intact copy of the T-DNA insert in a single locus within the cotton genome. • Extensive evaluation of the introduced proteins expressed in MON 88701, dicamba monooxygenase (MON 88701 DMO) and phosphinothricin acetyltransferase [PAT (bar)], confirmed they are unlikely to be toxins or allergens. In addition, PAT proteins are in several other commercially-available crops that have been reviewed and previously deregulated by USDA, including those in cotton, corn, soy, canola, sugarbeet, and rice. and • A compositional assessment of cottonseed confirmed that MON 88701 is compositionallyregime. equivalent to commercially cultivated cotton. • An extensive evaluation of phenotypic, agronomic, and plant mapping characteristics, as well as environmental interactions of MON 88701, demonstrated no increased plant pest potential protectionpublishing compared to commercially cultivated cotton. and • An assessment of potential impact on non-target organisms (NTOs)data indicated that, under anticipated agricultural conditions, MON 88701 is unlikely to have adverseand/orcontents effects on these organisms compared to commercially cultivatedproperty cotton. its AG therefore • Evaluation of MON 88701 using current agronomic management practicesor for cotton concluded that deregulation of MON 88701 is not likely to impactregulatory cotton agronomic may practices or land use, with the exception of the Bayerexpanded window of dicambaa application. of intellectual reproduction document These studies establish the food, feed andas environmentalparties.under safety of MON 88701 cotton by demonstrating the safety to humans and animals, establishing equivalent nutritionaldocument composition and wholesomeness fall this compared to conventionalproperty cotton such varieties, third and confirmingof that the potential impact on the environment is no different than conventional cotton varieties.this owner. the may distribution,of and use its is rights affiliates. of to and its owner owner of document rights the publication, the documentany subject of of this the be any This exploitation and/or may rights violate It permission copy and Furthermore, the commercial Consequently, any This document is protectedwithout underprohibited national and international copyright law and treaties.

It is the most widely used herbicide in the world, and the third most commonly used in North America.[1] 2,4-D is also an important synthetic auxin, often used in laboratories for plant research and as a supplement in plant cell culture media such as MS medium. History 2,4-D was developed during World War II by a British team at Rothamsted Experimental Station, under the leadership of Judah Hirsch Quastel, aiming to increase crop yields for a nation at war.[citation needed] When it was commercially released in 1946, it became the first successful selective herbicide and allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crop, because it only kills dicots, leaving behind monocots. Mechanism of herbicide action 2,4-D is a synthetic auxin, which is a class of plant growth regulators.

Zahoor A. Ganie and Amit J. Jhala* Department of Agronomy and Horticulture, University of Nebraska-Lincoln, Lincoln, NE, United States Glyphosate-resistant (GR) giant ragweed is a problematic broadleaf weed in crops including maize and soybean in the Midwestern United States. Commercialization of crops with 2,4-D or dicamba and glufosinate resistance will allow post-emergence (POST) applications of these herbicides. Therefore, information is needed on how Edited by: 2,4-D/dicamba will interact with glufosinate in various rate combinations. The objectives Ilias Travlos, Agricultural University of Athens, of this study were to evaluate the interaction of glufosinate plus 2,4-D and/or dicamba for Greece control of GR giant ragweed, and to determine their effect on GR giant ragweed density, Reviewed by: biomass, maize injury, and yield.

  • Control of Glyphosate-Resistant Common Waterhemp (Amaranthus Rudis)In Glufosinate-Resistant Soybean
    Weed Technology 2017 31:32–45 © Weed Science Society of America, 2017 Control of Glyphosate-Resistant Common Waterhemp (Amaranthus rudis)in Glufosinate-Resistant Soybean Amit J. Jhala, Lowell D. Sandell, Debalin Sarangi, Greg R. Kruger, and Steven Z. Knezevic* Glyphosate-resistant (GR) common waterhemp has become a significant problem weed in Nebraska and several Midwestern states. Several populations of GR common waterhemp are also resistant to acetolactate synthase (ALS)-inhibiting herbicides, making them difficult to control with POST herbicides in GR soybean. Glufosinate-resistant (GFR) soybean is an alternate system for controlling GR common waterhemp, justifying the need for evaluating glufosinate-based herbicide programs. The objectives of this study were to compare POST-only herbicide programs (including one-pass and two-pass POST programs) with PRE followed by (fb) POST herbicide programs for control of GR common waterhemp in GFR soybean and their effect on common waterhemp density, biomass, and soybean yield. Field experiments were conducted in 2013 and 2014 near Fremont, NE in a grower’s field infested with GR common waterhemp. Glufosinate applied early- and late-POST provided 76% control of GR common waterhemp at 14 d after late-POST (DALPOST) compared with 93% control with a PRE fb POST program when averaged across treatments. The PRE application of chlorimuron plus thifensulfuron plus flumioxazin, S-metolachlor plus fomesafen or metribuzin, saflufenacil plus dimethenamid-P fb glufosinate provided ≥95% control of common waterhemp throughout the ≤ −2 ≥ growing season, reduced common waterhemp− density to 2.0 plants m ,caused 94% biomass reduction, and led to 1,984 to 2,210 kg ha 1 soybean yield.

THE IMPACT OF DAS-40278-9 ON CORN HERBICIDE USE Summary of herbicide use Dow’s DAS-402787-9 corn is genetically engineered for resistance to 2,4-D and quizalofop, and if deregulated would be marketed with additional resistance to glyphosate and likely glufosinate – fostering greater use of three to four herbicide classes. APHIS must assess DAS-42078-9 as Dow intends it to be used, as a weed control system. DAS-40278-9 eliminates the risk of crop injury that currently limits 2,4-D use on corn, and is thus reasonably projected to trigger an up to 30-fold increase in the use of this toxic herbicide on corn, equivalent to a four-fold increase in overall agricultural use of 2,4-D, by the end of the decade.

Since herbicides mixes and rotations are an important alternative Glutamine synthetase for resistant weed management, the objective of this work was to evaluate the interaction of the dose inhibitor of the herbicides glufosinate and atrazine on ryegrass control and its seeds’ quality exposed to their Lolium multiflorum association. For this study, three experiments were carried out using factorial design in field, laboratory, Photosystem II inhibitor and greenhouse conditions. Two factors (A and B) were evaluated in each experiment, where factor A and B represented the doses of glufosinate and atrazine, respectively. Ryegrass control was evaluated in field experiment, while germination percentage and Emergence Speed Index (ESI), were obtained in laboratory and greenhouse analyses, respectively. The data were submitted to variance analysis (P≤0.05) and the significant results were analyzed through response surface graphs. For ryegrass control data, the effect of the interaction was analyzed by the Colby method; glufosinate provides efficient ryegrass control, but its association with atrazine reduces the efficiency, being characterized as an antagonism between molecules.

  • Herbicide Programs for Control of Glyphosate-Resistant Volunteer Corn in Glufosinate-Resistant Soybean
    Weed Technology 2015 29:431–443 Herbicide Programs for Control of Glyphosate-Resistant Volunteer Corn in Glufosinate-Resistant Soybean Parminder S. Chahal and Amit J. Jhala* Glyphosate-resistant (GR) volunteer corn is a significant problem weed in soybean grown in rotation with corn in the midwestern United States and eastern Canada. The objective of this study was to evaluate the efficacy of glufosinate applied in single or sequential applications compared with acetyl- coenzyme A carboxylase (ACCase) inhibitors applied alone or tank mixed with glufosinate for controlling GR volunteer corn in glufosinate-resistant soybean. At 15 d after early-POST (DAEP), ACCase inhibitors applied alone controlled volunteer corn 76 to 93% compared to 71 to 82% control when tank mixed with glufosinate. The expected volunteer corn control achieved by tank mixing ACCase inhibitors and glufosinate was greater than the glufosinate alone, indicating that glufosinate antagonized ACCase inhibitors at 15 DAEP, but not at later rating dates. ACCase inhibitors applied alone or tank mixed with glufosinate followed by late-POST glufosinate application controlled volunteer corn and green foxtail 97% at 30 DAEP. Single early-POST application of glufosinate controlled common waterhemp and volunteer corn 53 to 78%, and green foxtail 72 to 93% at 15 DAEP. Single as well as sequential glufosinate applications controlled green foxtail and volunteer corn greater than or equal to 90%, and common waterhemp greater than 85% at 75 d after late-POST (DALP). Contrast analysis suggested that glufosinate applied sequentially provided greater control of volunteer corn at 15 and 75 DALP compared to a single application. Similar results were reflected in volunteer corn density and biomass at 75 DALP.
