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. -

Throughout, it is clear that the path of agriculture begins with the seed. Over the past 40 years, the U.S. has led a radical shift toward commercialization, consolidation, and control of seed. Prior to the advent of industrial agriculture, there were thousands of seed companies and public breeding institutions.

The United States' Chemical Defoliant Use During the Vietnam War and Its
ABSTRACT OATSVALL, NEIL SHAFER. War on Nature, War on Bodies: The United States’ Chemical Defoliant Use During the Vietnam War and Its Consequences. (Under the direction of Matthew Morse Booker.) During most of the Vietnam War, from 1961-1971, the United States military sprayed chemical defoliants on a significant part of the Vietnamese environment in order to gain a military advantage. US forces used these chemicals in an attempt to substitute technology and financial resources for manpower to triumph over a relatively technologically deficient enemy. This effort, dubbed “Operation Ranch Hand,” wrought incredible destruction not only on Vietnam’s natural setting, but also on everyone involved; Vietnamese and American, civilian and soldier. This work examines the consequences of defoliation, and aims to show that those outcomes proved more severe in both scale and efficacy than any anticipated results. It differs from previous studies by combining environmental, military, medical, and cultural factors and considering them as interrelated. Whenever possible this study also tries to bring in a Vietnamese perspective, though that is often impossible due to a lack of available evidence in English. In this war, the United States treated not only the Vietnamese Communists as enemies but also assaulted the natural environment as foe. The interconnections forged during this complicated interpretation of nature and enemy are essential to the study of Operation Ranch Hand and chemical defoliation operations. Nature mattered to both sides, and an -
Air America in South Vietnam I – from the Days of CAT to 1969
Air America in South Vietnam I From the days of CAT to 1969 by Dr. Joe F. Leeker First published on 11 August 2008, last updated on 24 August 2015 I) At the times of CAT Since early 1951, a CAT C-47, mostly flown by James B. McGovern, was permanently based at Saigon1 to transport supplies within Vietnam for the US Special Technical and Economic Mission, and during the early fifties, American military and economic assistance to Indochina even increased. “In the fall of 1951, CAT did obtain a contract to fly in support of the Economic Aid Mission in FIC [= French Indochina]. McGovern was assigned to this duty from September 1951 to April 1953. He flew a C-47 (B-813 in the beginning) throughout FIC: Saigon, Hanoi, Phnom Penh, Vientiane, Nhatrang, Haiphong, etc., averaging about 75 hours a month. This was almost entirely overt flying.”2 CAT’s next operations in Vietnam were Squaw I and Squaw II, the missions flown out of Hanoi in support of the French garrison at Dien Bien Phu in 1953/4, using USAF C-119s painted in the colors of the French Air Force; but they are described in the file “Working in Remote Countries: CAT in New Zealand, Thailand-Burma, French Indochina, Guatemala, and Indonesia”. Between mid-May and mid-August 54, the CAT C-119s continued dropping supplies to isolated French outposts and landed loads throughout Vietnam. When the Communists incited riots throughout the country, CAT flew ammunition and other supplies from Hanoi to Saigon, and brought in tear gas from Okinawa in August.3 Between 12 and 14 June 54, CAT captain -

As part of this program, the BLM is proposing the use of ten herbicide active ingredients (a.i.) to control invasive plants and noxious weeds on approximately one million of the 6 million acres proposed for treatment. The BLM and its contractor, ENSR, are preparing a Vegetation Treatments Programmatic Environmental Impact Statement (EIS) to evaluate this and other proposed vegetation treatment methods and alternatives on lands managed by the BLM in the western continental US and Alaska. -

Air America in South Vietnam III the Collapse by Dr
Air America in South Vietnam III The Collapse by Dr. Joe F. Leeker First published on 11 August 2008, last updated on 24 August 2015 Bell 205 N47004 picking up evacuees on top of the Pittman Building on 29 April 1975 (with kind permission from Philippe Buffon, the photographer, whose website located at http://philippe.buffon.free.fr/images/vietnamexpo/heloco/index.htm has a total of 17 photos depicting the same historic moment) 1) The last weeks: the evacuation of South Vietnamese cities While the second part of the file Air America in South Vietnam ended with a China Airlines C-123K shot down by the Communists in January 75, this third part begins with a photo that shows a very famous scene – an Air America helicopter evacuating people from the rooftop of the Pittman Building at Saigon on 29 April 75 –, taken however from a different angle by French photographer Philippe Buffon. Both moments illustrate the situation that characterized South Vietnam in 1975. As nobody wanted to see the warnings given by all 1 those aircraft downed and shot at,1 the only way left at the end was evacuation. For with so many aircraft of Air America, China Airlines and even ICCS Air Services shot down by Communists after the Cease-fire-agreement of January 1973, with so much fighting in the South that occurred in 1973 and 1974 in spite of the Cease-fire-agreement, nobody should have been surprised when North Vietnam overran the South in March and April 75. Indeed, people who knew the situation in South Vietnam like Major General John E.
