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. -
Nitrogen Source for Inflorescence Development in Phalaenopsis: I

Phalaenopsis orchid is a slow-growing crop that responds slowly to fertilization. In this study, we used 15N- labeled Johnson’s solution to investigate the accumulation and use of fertilizer nitrogen (N) during the vegetative and reproductive growth stages of Phalaenopsis Sogo Yukidian ‘V3’ with a focus on the nitrogen source for inflorescence development. Labeling of fertilizer applied to mature plants 6 weeks before forcing or at 6 weeks into forcing showed that in the inflorescence, the ratio of N derived from fertilizer applied 6 weeks before forcing to the N derived from fertilizer applied 6 weeks into forcing was 31% to 69%, which shows the importance of newly absorbed fertilizer for supplying the N needed for inflorescence development. The fate of fertilizer N applied during the small, medium, or large plant stage of vegetative Phalaenopsis Sogo Yukidian ‘V3’ was traced separately with 15N-labeling. The capacity of the plant to accumulate N after fertilizer application was different during the various stages of vegetative growth, with large plants having more N storage capacity as a result of their greater biomass. However, the percentage of the accumulated N that was later allocated to the inflorescence was similar regardless of the stage of fertilizer application: of the fertilizer N absorbed during various stages of the vegetative period, 6% to 8% was allocated to the inflorescence at the visible bud stage. -

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 -

TOWARDS AN INTEGRATED MARKET FOR SEEDS AND FERTILIZERS IN WEST AFRICA Abstract To improve farmer access to quality seeds and fertilizers, West African governments have been working through ECOWAS and other regional organizations to develop harmonized rules for input trade for many years. After extensive consultations, regional regulations based on advanced international standards have mostly been agreed upon and are already helping to guide quality improvements in some countries. Despite these encouraging signs, most countries do not currently have the physical capacity or institutional structures needed to implement the agreed trade rules which will take considerable time and investment to develop. The analysis, therefore, points to a need for pragmatic solutions that are easy for individual countries or groups of countries to implement in the near term while longer-term progress towards full harmonization continues. Key words Africa, regional trade, crop inputs, harmonization Acknowledgements This working paper is the result of numerous consultations with seed, fertilizer, and regional trade experts in West Africa who generously gave their time for interviews, for sharing data, and for answering questions after the country visits. The complete list of individuals met is too long for this page, but the team would like everyone to know that their time and efforts are greatly appreciated. -

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. -

Fully Trap the Limiting Resource (P) Until P Becomes Totally Restricted
Annals of Tropical Research 4123242 ( ): - (201 9 ) © VSU, Leyte, Philippines Direct 33P labeling approach is a very powerful technique that has high sensitivity in tracing the fate of added phosphorus (P) fertilizers across various P pools. Nonetheless, only a few studies have used this approach. This study traced the fate of applied P fertilizer in acidic P-limited soil using the 33 P labeling approach. 33 The incorporation of P-labeled KH2 PO 4 in available P (P AEM ), microbial biomass P (Pmic ) and Fe/Al-bound P (P NaOH ) pools was followed in Cambisol as influenced by C and N sources applied as glucose and ammonium sulfate, respectively. Results showed that not all of the added P fertilizer remains in available pool; instead, it was distributed to poorly-available pools. Fast, almost instantaneous P fixation by the Fe and Al oxides and immobilization by microbial uptake were recorded. Applying glucose boosts microbial growth and demand for P, resulting in increased 33P 33 33 recovery. High P recovery in Pmic (20% of the applied P) and in P NaOH (45% of applied 33P) showed the dominance of P immobilization by microorganisms and adsorption by Fe and Al oxides on the fate of P in an acidic soil. Nevertheless, these can contribute to long-term P availability after the turnover of microbial biomass and desorption of fixed P. Keywords: 33P isotopic labeling, Phosphorus dynamics , Phosphorus availability , Phosphorus fractions, Microbial biomass P , P-limited soil Phosphorus (P) as orthophosphate is essential to life as a structural and functional component of all living organisms and cannot be substituted by any other nutrient (Chimdi et al 2014, Frossard et al 2016).
