Download or read book Aerial Application Equipment for Herbicidal Drift Reduction written by R. E. Stewart and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides silviculturists and managers of utility rights-of-way with a description and evaluation of available helicopter spray application equipment. Modified conventional equipment will reduce drift of sprays in normal carriers and apply various high-viscosity sprays. Specialized spray systems have found limited use in forestry; they are more commonly used on utility rights-of-way. Most of the available spray systems or spray adjuvants reduce but do not completely eliminate drift. Maximum drift reduction with present equipment and adjuvants is obtained with the Microfoil Boom.

Book excerpt: Increased public concern about pesticides requires that foresters reduce drift and insure precise application of herbicides to the areas requiring treatment. Drift control is necessary near waterways and other ecologically sensitive areas. This publication discusses available drift control adjuvants for herbicidal sprays. These include invert emulsions, thickening agents, particulating agents, and foam sprays. Commercially available adjuvants are described and their use, advantages, and disadvantages are discussed. Thickening agents and foam sprays show special promise for drift reduction in aerial application of herbicides on forest lands.
Download or read book Spray Drift Reduction Test Method Correlation written by Bradley K. Fritz and published by . This book was released on 2014 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drift reduction agent has been defined in ASTM E1519-10 [ASTM E1519-10: Terminology Relating to Agricultural Tank Mix Adjuvants, Annual Book of ASTM Standards, ASTM International, West Conshohocken, PA, 2010] as "a material used in liquid spray mixtures to reduce driftable fines." Driftable fines are defined as "the % volume of a spray droplet size distribution with a diameter less than 105 microns." ASTM E609-10 [ASTM E609-10: Terminology Relating to Pesticides, Annual Book of ASTM Standards, ASTM International, West Conshohocken, PA, 2010] defines drift as "The physical movement of an agrochemical through the air at the time of application or soon thereafter to any non or off target site. Drift shall not include movement to non or off-target sites caused by erosion, migration, volatility or wind-blown soil particles that occur after application unless specifically advertised on the label." Because there are many commercial tank mix adjuvants designed to reduce spray drift, ASTM established a standard test method to evaluate their effectiveness. ASTM E2798-11 [ASTM E2798-11: Characterization of Performance of Spray Drift Reduction Adjuvants for Ground Application, Annual Book of ASTM Standards, ASTM International, West Conshohocken, PA, 2011] provides guidelines for the measurement of parameters pertaining to the performance of drift-reduction adjuvants under simulated field application conditions. The measurements can be made in a wind tunnel or lab spray chamber to represent ground applications. The method describes the preparation, composition and test/application conditions for droplet size and driftable fines measurements. The U.S. Environmental Protection Agency has published a proposed protocol covering the implementation of spray drift reduction technologies in the field. The results of ASTM E2798 were compared to drift reduction simulated by AGDISP (Continuum Dynamics, Ewing, NJ) to see whether a correlation between the two test methods exists.
Download or read book Pesticide Application Methods written by Graham Matthews and published by John Wiley & Sons. This book was released on 2014-01-06 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: PESTICIDE APPLICATION METHODS Pesticide Application Methods is the standard work for all those involved in crop protection. This fully revised and expanded edition provides up-to-date information on the different types of application techniques and how they should be used to ensure efficient and effective pest control. The third edition of this excellent book was published more than 10 years ago, since when a number of important developments have taken place. Examples include changes to legislation both in the EU and USA concerning water quality. This has an impact on how spray is applied and, more particularly, how the sprayer is designed to minimise quantities that remain in the equipment when spraying is completed, and in addition inform how and when the sprayer is cleaned. Concern about spray drift has also continued and has led to more research on how to reduce the amount of spray that moves downwind from a treated area. Important new information on this topic is included within the new edition. Professor Graham Matthews has been joined by two new co-authors to increase the breadth and depth of coverage in this updated edition of Pesticide Application Methods. This important new edition is a commercially significant reference tool and will be of great use and interest to all those working in crop protection, including agricultural entomologists and plant pathologists, pesticide scientists, advisors and consultants, large-scale growers, agricultural and horticultural scientists, agrochemical industry personnel including those involved in equipment supply and product formulation. Libraries in government and commercial research establishments, universities and agricultural colleges where agricultural and biological sciences are studied and taught should have multiple copies of this definitive book on their shelves.
Download or read book Validation Testing of Drift Reduction Technology Testing Protocol written by Faruque A. Khan and published by . This book was released on 2010 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of pesticide application technologies offer the potential to reduce spray drift from pesticide applications. However, limited information exists on the effectiveness of these technologies in reducing spray drift. Working with a stakeholder technical panel under EPA's Environmental Technology Council, the Office of Pesticide Programs in EPA has developed and is in the process of validating a testing protocol to verify the effectiveness of drift reduction technologies (DRTs). The DRT testing protocol was adapted from standard test methods and regulatory methods used in other countries and describes the testing approach that will be used to generate high-quality, peer-reviewed data for DRTs, including test design and quality assurance aspects. Both low-speed and high-speed wind tunnel tests were completed using a reference nozzle and two test nozzles to evaluate the performance of the generic DRT testing protocol. By Summer 2010, EPA anticipates to finalize this testing protocol based on the test results performed by EPA and other stakeholders. As a next step, EPA intends to encourage equipment manufacturers to voluntarily use the protocol for testing their equipment. Tested technologies that are proven to significantly reduce spray drift may be considered for addition to pesticide product labels by pesticide registrants and by EPA in its risk assessment and management decisions for the registration of new pesticide and uses and registration review (reevaluation) of currently registered pesticides. Pesticide product labels citing the use of DRTs could have reduced restrictions for applications, provide applicators with greater flexibility, and result in less off-target pesticide deposition. This paper will provide an update of EPA's efforts to validate the DRT testing protocol and discuss future plans for using a validated protocol in evaluating DRTs in an effort to reduce load from unintended spray drift of pesticides in the environment.

Download or read book Pesticides written by Graham Matthews and published by John Wiley & Sons. This book was released on 2016-01-13 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop protection continues to be an important component of modern farming to maintain food production to feed an expanding human population, but considerable changes have occurred in the regulation of pesticides in Europe in the last decade. The aim has been to reduce their impact on people and the environment. This has resulted in a major reduction in the number of chemicals approved for application on crops. In other parts of the world, a continuing expansion in the growing of genetically modified crops has also changed the pattern of pesticide use. In this second edition, Graham Matthews, updates how pesticides are registered and applied and the techniques used to mitigate their effects in the environment. Information on operator safety, protection of workers in crops treated with pesticides and spray drift affecting those who live in farming areas is also discussed. By bringing together the most recent research on pesticides in a single volume, this book provides a vital up to date resource for agricultural scientists, agronomists, plant scientists, plant pathologists, entomologists, environmental scientists, public health personnel, toxicologists and others working in the agrochemical industry and governments. It should assist development of improvements in harmonising regulation of pesticides in countries with limited resources for registration of pesticides.
