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. -

Exposure to Herbicides in House Dust and Risk of Childhood Acute Lymphoblastic Leukemia
Journal of Exposure Science and Environmental Epidemiology (2013) 23, 363–370 & 2013 Nature America, Inc. All rights reserved 1559-0631/13 www.nature.com/jes ORIGINAL ARTICLE Exposure to herbicides in house dust and risk of childhood acute lymphoblastic leukemia Catherine Metayer1, Joanne S. Colt2, Patricia A. Buffler1, Helen D. Reed3, Steve Selvin1, Vonda Crouse4 and Mary H. Ward2 We examine the association between exposure to herbicides and childhood acute lymphoblastic leukemia (ALL). Dust samples were collected from homes of 269 ALL cases and 333 healthy controls (o8 years of age at diagnosis/reference date and residing in same home since diagnosis/reference date) in California, using a high-volume surface sampler or household vacuum bags. Amounts of agricultural or professional herbicides (alachlor, metolachlor, bromoxynil, bromoxynil octanoate, pebulate, butylate, prometryn, simazine, ethalfluralin, and pendimethalin) and residential herbicides (cyanazine, trifluralin, 2-methyl-4- chlorophenoxyacetic acid (MCPA), mecoprop, 2,4-dichlorophenoxyacetic acid (2,4-D), chlorthal, and dicamba) were measured. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Models included the herbicide of interest, age, sex, race/ethnicity, household income, year and season of dust sampling, neighborhood type, and residence type. The risk of childhood ALL was associated with dust levels of chlorthal; compared to homes with no detections, ORs for the first, second, and third tertiles were 1.49 (95% CI: 0.82–2.72), 1.49 (95% CI: 0.83–2.67), and 1.57 (95% CI: 0.90–2.73), respectively (P-value for linear trend ¼ 0.05). The magnitude of this association appeared to be higher in the presence of alachlor. -

Weed Management—Major Crops
Weed Technology 2010 24:1–5 Weed Management—Major Crops Annual Grass Control in Strip-Tillage Peanut Production with Delayed Applications of Pendimethalin W. Carroll Johnson, III, Eric P. Prostko, and Benjamin G. Mullinix, Jr.* In strip-tillage peanut production, situations occur when dinitroaniline herbicides are not applied in a timely manner. In these cases, dinitroaniline herbicides would be applied days or weeks after seeding. However, there is no information that documents the effects of delayed applications on weed control. Trials were conducted in 2004, 2005, and 2007 in Georgia to determine the weed control efficacy of delayed applications of pendimethalin in strip-tillage peanut production. Treatments included seven timings of pendimethalin application and three pendimethalin-containing herbicide combinations. Timings of application were immediately after seeding (PRE), vegetative emergence of peanut (VE), 1 wk after VE (VE+1wk), VE+2wk, VE+3wk, VE+4wk, and a nontreated control. Pendimethalin containing herbicide programs included pendimethalin plus paraquat, pendimethalin plus imazapic, and pendimethalin alone. Among the possible treatment combinations was a current producer standard timing for nonpendimethalin weed control programs in peanut, which was either imazapic or paraquat alone applied VE+3wk. Pendimethalin alone did not effectively control Texas millet regardless of time of application (69 to 77%), whereas southern crabgrass was controlled by pendimethalin alone PRE (87%). Delayed applications of pendimethalin controlled Texas millet and southern crabgrass when combined with either paraquat or imazapic, with imazapic being the preferred combination due to better efficacy on southern crabgrass than paraquat at most delayed applications. Peanut yield was improved when any of the herbicide combinations were applied PRE compared to later applications. -

Use of Mesotrione for Annual Bluegrass (Poa Annua L.) at Cool
USE OF MESOTRIONE FOR ANNUAL BLUEGRASS (POA ANNUA L.) AT COOL- SEASON TURFGRASS ESTABLISHMENT by KATELYN A. VENNER A Thesis submitted to the Graduate School-New Brunswick Rutgers, The State University of New Jersey in partial fulfillment of the requirements for the degree of Master of Science Graduate Program in Plant Biology written under the direction of Stephen E. Hart Ph.D. and approved by ________________________ ________________________ ________________________ New Brunswick, New Jersey October, 2011 ABSTRACT OF THE THESIS USE OF MESOTRIONE AT COOL-SEASON TURFGRASS ESTABLISMENT By Katelyn Anne Venner Thesis director: Stephen E. Hart Annual bluegrass is a problematic weed in highly maintained turfgrass environments, and is difficult to control due to its adaptability to highly maintained turfgrass environments and lack of highly effective chemical control options. Mesotrione is a relatively new herbicide which has been found to show some level of control of annual bluegrass, and is safe to use at cool season turfgrass establishment. Thus, mesotrione has potential to be utilized for weed control in cultivated sod production. The objectives of this research were to evaluate mesotrione to determine: 1) tolerance of selected tall fescue cultivars, an important turfgrass species cultivated for sod, to applications of mesotrione; 2) the length of residual of mesotrione versus prodiamine, bensulide and dithiopyr for control of annual bluegrass; and 3) potential of mesotrione to control winter annual broadleaf weeds at Kentucky bluegrass establishment. Tall fescue cultivars were found to be tolerant to mesotrione applications made preemergence and preemergence plus 4 weeks after emergence at higher rates than required for weed control.
