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. -

CFS Science Comments I
April 27, 2012 Docket No. APHIS–2010–0103 Regulatory Analysis and Development PPD, APHIS Station 3A-03.8 4700 River Road Unit 118 Riverdale, MD 20737-1238 Comments to USDA APHIS on Environmental Assessment for the Determination of Nonregulated Status of Herbicide-Tolerant DAS-40278-9 Corn, Zea mays, Event DAS- 40278-9 Center for Food Safety, Science Comments I – By Bill Freese, Science Policy Analyst These comments submitted by Center for Food Safety are one of three sets of comments from our organization. Legal comments and a second set of science comments are also being submitted. The references cited have been uploaded as supporting materials. The filenames for these documents match the citations in the text, and are all incorporated as (e.g. Benbrook 2012). Full citations are included at the end of each section. 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. -

The Evaluation of HPPD-Inhibitors for Full-Season Control of Morningglory (Ipomoea) Species in Corn (Zea mays L.) by James Daniel Jones III A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 15, 2018 Keywords: Ipomoea, corn, HPPD, postemergence Approved by Dr. Dennis Delaney, Chair, Extension Specialist, Crop, Soil, and Environmental Sciences Dr. Andrew Price, Affiliate Associate Professor, Crop, Soil, and Environmental Sciences Dr. Audrey Gamble, Assistant Professor and Extension Specialist, Crop, Soil, and Environmental Sciences i Abstract Due to late-season morningglory harvest interference concerns in corn, field studies were conducted in 2017 and 2018 at the Prattville Agricultural Research Unit in Prattville, Alabama and at the Sand Mountain Research and Extension Center in Crossville, Alabama to evaluate late season control of morningglory species using HPPD- inhibitors postemergence (POST) applied alone, following atrazine preemergence (PRE), or in combination with atrazine. Additionally, Amaranthus spp. and Senna spp. were evaluated for control. An incomplete randomized design with a split-plot treatment arrangement with four replications was utilized. The trial was divided into two sections: one with a PRE application of atrazine and a second without a preemergence application of atrazine. Eleven herbicides were applied POST without atrazine including: tembotrione; mesotrione; topramezone+dimethenamid; mesotrione+S- metolachlor+glyphosate; tembotrione+thiencarbazone; topramezone; mesotrione+S- metolachlor+atrazine; mesotrione+S-metolachlor+atrazine+bicyclopyrone; mesotrione+nicosulfuron; isoxaflutole; isoxaflutole+thiencarbazone-methyl; non-treated with atrazine applied PRE, and a true non-treated check. The same herbicides, excluding the two treatments that contain atrazine in the premixture, were also applied with atrazine. -

The predicted lethality of mesotrione on each spider species based upon soil association levels and species size. Toxicity is predicted to increase with smaller size and Mesotrione is a widely used agricultural herbicide and is frequently used alone or as an adjuvant for the Susquehanna University’s campus. Each spider was housed in a 473 ml (16oz) greater soil contact. Sample sizes for each species are indicated to the left. A total of 615 herbicides glyphosate and atrazine. The effects of mesotrione are largely untested on beneficial non-target spiders were used in this study. species such as spiders. -
