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.

  • Redox Imbalance Caused by Pesticides: a Review of OPENTOX-Related Research
    Marjanović Čermak AM, et al. Redox imbalance caused by pesticides Arh Hig Rada Toksikol 2018;69:126-134 126 Review DOI: 10.2478/aiht-2018-69-3105 Redox imbalance caused by pesticides: a review of OPENTOX-related research Ana Marija Marjanović Čermak, Ivan Pavičić, and Davor Želježić Institute for Medical Research and Occupational Health, Zagreb, Croatia [Received in February 2018; Similarity Check in February 2018; Accepted in May 2018] Pesticides are a highly diverse group of compounds and the most important chemical stressors in the environment. Mechanisms that could explain pesticide toxicity are constantly being studied and their interactions at the cellular level are often observed in well-controlled in vitro studies. Several pesticide groups have been found to impair the redox balance in the cell, but the mechanisms leading to oxidative stress for certain pesticides are only partly understood. As our scientific project “Organic pollutants in environment – markers and biomarkers of toxicity (OPENTOX)” is dedicated to studying toxic effects of selected insecticides and herbicides, this review is focused on reporting the knowledge regarding oxidative stress-related phenomena at the cellular level. We wanted to single out the most important facts relevant to the evaluation of our own findings from studies conducted onin vitro cell models. KEY WORDS: antioxidants; apoptosis; glyphosate; in vitro; neonicotinoids; organophosphates; oxidative stress; pyrethroids; reactive oxygen species Over the years, population growth and changes in food (HrZZ), is dedicated to studying the toxic effects of two consumption patterns have challenged agricultural major pesticide classes with three subgroups each: (A) production to meet the demand for food and quality insecticides (organophosphates, neonicotinoids, and standards.

Th e treatments were car- [email protected] ried out in a laid randomized block design with 4 replications. Th e results showed that the tested herbicides applied at split doses were eff ective in weed control. Aft er the herbicide application weed density and weed biomass were signifi cantly reduced compared to the infested control. Th e best results were achieved aft er the application of mesotrione tank mixture with s-metolachlor and terbuthylazine. Application of split doses of herbicides was also correlated with the density, biomass, and height of sorghum. Key words: herbicides, mesotrione, s-metolachlor, sorghum, split doses, terbuthylazine, weed control Introduction Sorghum, the oldest cultivated crop in the world, is a total area of 390,000 ha.

  • PESTICIDES Criteria for a Recommended Standard
    CRITERIA FOR A RECOMMENDED STANDARD OCCUPATIONAL EXPOSURE DURING THE MANUFACTURE AND FORMULATION OF PESTICIDES criteria for a recommended standard... OCCUPATIONAL EXPOSURE DURING THE MANUFACTURE AND FORMULATION OF PESTICIDES * U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health July 1978 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 DISCLAIMER Mention of company names or products does not constitute endorsement by the National Institute for Occupational Safety and Health. DHEW (NIOSH) Publication No. 78-174 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and provide for the safety of workers occupationally exposed to an ever-increasing number of potential hazards. The National Institute for Occupational Safety and Health (NIOSH) has implemented a formal system of research, with priorities determined on the basis of specified indices, to provide relevant data from which valid criteria for effective standards can be derived. Recommended standards for occupational exposure, which are the result of this work, are based on the effects of exposure on health. The Secretary of Labor will weigh these recommendations along with other considerations, such as feasibility and means of implementation, in developing regulatory standards. Successive reports will be presented as research and epideiriologic studies are completed and as sampling and analytical methods are developed. Criteria and standards will be reviewed periodically to ensure continuing protection of workers. The contributions to this document on pesticide manufacturing and formulating industries by NIOSH staff members, the review consultants, the reviewer selected by the American Conference of Governmental Industrial Hygienists (ACGIH), other Federal agencies, and by Robert B.

Investigations were carried out at the Runoff Monitoring Station of the University of Bologna (Italy). Glyphosate and glufosinate-ammonium were applied as pre-emergence herbicides on 350-m2 field plots characterized by a uniform slope of 15%.
