Available in PDF, EPUB and Kindle. Book excerpt: Studies of Adjuvants involve many scientific fields from basic research of the chemistry, through investigations into physiological effects and environmental impact, to mixture formulation and field use. These important areas are illustrated in these two volumes, which are contributions from the First International Symposium on Adjuvants for Agrochemicals, held in Brandon, Manitoba on August 5 to 7, 1986. A total of 200 participants from 19 countries met to discuss their common interest in adjuvant science, technology, and application. It is the editors hope that these volumes will stimulate interest in and promote a better understanding of the chemical, physiological, and agronomic aspects of adjuvants as they relate agrochemicals. In addition, the revisedAdjuvants for Agrochemicals: A Selected Bibliography of World Literature in the English Language will be a valuable resource for agricultural researchers and other users. We hope that adjuvant research will lead to even safer, more efficient, and more economical use of chemicals in agriculture and forestry.

Available in PDF, EPUB and Kindle. 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.

Book excerpt: Herbicides are one of the most widely used groups of pesticides worldwide for controlling weedy species in agricultural and non-crop settings. Due to the extensive use of herbicides and their value in weed management, herbicide research remains crucial for ensuring continued effective use of herbicides while minimizing detrimental effects to ecosystems. Presently, a wide range of research continues to focus on the physiology of herbicide action, the environmental impact of herbicides, and safety. The authors of Herbicides, Physiology of Action, and Safety cover multiple topics concerning current valuable herbicide research.

Book excerpt: Adjuvants are any substance either added in a herbicide formulation or added to the spray tank that modifies herbicidal activity or application characteristics, such as better mixing and handling, increasing droplet coverage, spray retention and droplet drying, increasing herbicide cuticle penetration and cellular accumulation reducing leaching of herbicide through the soil profile, et cetera The interactions between herbicide adjuvants and herbicide activity, however, are not simple processes, and depend on factors that include crop/weed leaf surface, droplet characteristics, adjuvant type, chemical form of the herbicide, and environmental conditions. Understanding the complexity of these interactions is essential for optimum herbicide utilization, particularly in prolonging, enhancing and improving the efficacy; reduction of the critical rain-free period; minimizing herbicide leaching into groundwater; and decreasing harmful effects to non-target plants and animals.

This book was released on 2013-03-14 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the importance of adjuvants for optimising the activity of agrochemicals has become increasingly recognized. This book is aimed at accumulating the current knowledge of the interactions between adjuvants, agrochemicals and target organisms. It provides results, and ideas for future research and defines new methodological, biomechanistic and systematic approaches which can be implemented to streamline research and development of formulations and adjuvant/active ingredient combinations. The book contains micrographs of leaf surfaces and spray deposits, graphical and statistical presentations, and data on the properties of adjuvants. In particular a case study is presented demonstrating the interactions possible between formulation and adjuvant types.

This book was released on 2014-09-02 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn is one of the essential crops in our world. Not only today but also in past.We can produce variety of products from corn, so planting of corn is important. We should produce more corn with less damage to environment. Today new methods are used to reduce the amount of herbicides dose. One of these ways is using Adjuvant or additives to increase the efficiency of herbicides. In this study we peruse the effect of some adjuvant on Nicosulfuron efficiency on agronomic traits of maize and some weeds density and biomass, a field experiment was conducted in research field of Miyaneh (Iran), based on randomized complete design with three replications.Treatments included T1: atrazine, T2: nicosulfuron + volck oil, T3: nicosulfuron + ammonium nitrate, T4: nicosulfuron + ammonium sulfate, T5: nicosulfuron + citogate, T6: nicosulfuron and T7: control. Results showed that the effect of herbicide and adjuvants application was significant on maize grain yield. Among different adjuvants, ammonium sulfate was more effective on studied traits than other adjuvants. Nicosulfuron plus ammonium sulfate increased grain yield 20.7% compared to control.

Download or read book Comparison of Herbicide Efficacy and Adjuvants Using a Conventional Sprayer and an Ultra Low Volume Sprayer written by Greg R. Kruger and published by . This book was released on 2014 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Ultra-Low Volume (ULV) sprayer was developed to decrease spray volume needed for crop production pesticide applications. A field study was conducted at the University of Nebraska-Lincoln: West Central Research and Extension Center Dryland Farm near North Platte, NE in 2011 and 2012 to determine efficacy of herbicide active ingredients when applied by a ULV sprayer compared to a conventional sprayer. The effect of four drift reducing adjuvants on glyphosate efficacy with an ULV sprayer at two pressures was also evaluated. Ten active ingredients with each sprayer and an untreated check (21 total treatments) were arranged in a randomized complete block design with four replications. The ten herbicides chosen were glyphosate, glufosinate, 2,4-D ester, dicamba, atrazine, saflufenacil, mesotrione, chloransulam-methyl, sodium salt of bentazon, and clethodim. Additionally, four drift reducing adjuvants, a glyphosate check and an untreated check were arranged in a randomized complete block design with four replications. The four adjuvants selected were hydroxyethyl cellulose (HEC), polyethylene oxide (PEO), methylated soybean oil (MSO), and glycerin. Treatments were applied across a 12 row plot planted to six different plant species. Plant species used were non-glyphosate-resistant corn (Zea mays L.) non-glyphosate-resistant soybeans (Glycine max (L.) Merr.), amaranth (Amaranthus hypochondriacus L.), quinoa (Chenopodium quinoa Willd.), velvetleaf (Abutilon theophrasti Medik.), and green foxtail (Setaria viridis (L.) Beauv.). Treatments in both studies were analyzed for their relative particle size on a laser diffraction instrument. Five plants of each species per plot were harvested four weeks after application, dried for 48 h at 63°C and dry weights were recorded. The active ingredient study yielded no difference in efficacy between sprayer types across all six species in 2011 but was different in corn in 2012. Simple effect differences of treatment by sprayer type were observed in both years. The adjuvant study had no difference in glyphosate efficacy across the four adjuvants or the glyphosate check over the six species in 2011 and corn and soybean in 2012. Additionally, pressure did not affect efficacy across all treatments. The results indicate that the ULV sprayer is potentially an effective method for delivering herbicides.
