Book Synopsis Comparison of Herbicide Efficacy and Adjuvants Using a Conventional Sprayer and an Ultra-Low Volume Sprayer by : Greg R. Kruger
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.

Book excerpt: Responsible for a high proportion of the world's crop losses, weedstake away food that the world badly needs. They decrease thequality and quantity of vegetable fibers, wool, and hides, andinterfere with fishing, irrigation, hydroelectric power production,and the movement of shipping vessels. In order to recognize thetrue magnitude of the weed problem, and to be better equipped todesign effective weed control methods, it is vital to identify andlearn as much as possible about the many different species of thisdestructive agricultural predator. The culmination of four decades of global research, World Weedspresents comprehensive and up-to-date information on over 100weeds--addressing recent changes in such areas as crop tillagemethods, herbicide use, and agricultural runoff. This monumentalwork, featuring a wealth of original data from the authors,provides extensive coverage of the known biology of each species.Each entry contains a full botanical description, plus importantdetails on habitat requirements and distribution, seed production,ecology, physiology, crop impact, and more. Generously suppliedwith dozens of unique illustrations and species distribution mapscovering over 100 countries, this definitive resource boasts anextensive multilingual index of common names, and a massivebibliography with over 3,000 references to facilitate furtherreading and research. World Weeds is a truly masterful referencethat will be celebrated by weed and crop scientists, botanists, andothers for years to come.
Book Synopsis Assessing Long-term Viability of Glyphosate-resistant Technology as a Foundation for Cropping Systems by : Jason Wade Weirich
Download or read book Assessing Long-term Viability of Glyphosate-resistant Technology as a Foundation for Cropping Systems written by Jason Wade Weirich and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of glyphosate-resistant (GR) crops in the late 1990s changed the way producers used herbicides to control weeds. Since the introduction of GR crops producers have relied on glyphosate alone for weed control instead of utilizing multiple modes of action for weed control. This over-reliance resulted in several weed species developing resistance to glyphosate. This has resulted in organizations from the public and private sector questioning the sustainability of GR cropping systems. Researchers from Illinois, Indiana, Iowa, Mississippi, Nebraska, and North Carolina established 156 on-farm trials to determine the sustainability of GR cropping systems. The objectives of this study were: to determine the economics of a university weed resistance best management practice (BMP) versus a producers' normal production practice; to evaluate when a producer that is risk neutral (profit maximizing) or risk averse should adopt a weed resistance BMP; and to compare the influences of using a university weed resistance BMP to a producer's normal production practice on the 27 most common weed species in Mississippi. In all instances, the university weed resistance BMP utilized multiple modes of action in conjunction with glyphosate. A university weed resistance BMP can provide the same level of control on 27 of the most common weeds in Mississippi that a producer has become accustomed to with a glyphosate alone system, while delaying or controlling GR weeds. A university weed resistance BMP resulted in an increase in weed control cost, but similar yields and economic returns when compared to a producer's normal production practice. Rotating a GR crop with a different GR crop resulted in higher economic returns when compared to a continuous GR cropping system or a GR crop followed by a non-GR crop rotation. Producers are often reluctant to adopt a weed resistance BMP because of the perceived increased cost for weed control. A risk neutral or risk averse producer should adopt a weed resistance BMP and feel confident that their decision will provide weed control equivalent to a glyphosate alone weed control program before resistance developed, delay or control GR weeds and be economically sound.
Book Synopsis Barnyardgrass Control in Mississippi with Different Herbicides and Herbicide Mixtures by : Hunter D. Bowman
Download or read book Barnyardgrass Control in Mississippi with Different Herbicides and Herbicide Mixtures written by Hunter D. Bowman and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the adoption of the Xtend® technology growers began to report reduced control levels of weedy grasses when applying tank-mixes of glyphosate and dicamba. Therefore, research was conducted at the Delta Research and Extension Center in Stoneville, MS from 2019 to 2021 to examine influence of herbicide mixtures with dicamba, as well as carrier volume and nozzle type. Results indicated barnyardgrass control 14 and 28 DAT was greatest with glyphosate alone. Control was not different when DGA or BAPMA dicamba or 2,4-D choline were mixed with glyphosate. At 28 DAT, barnyardgrass control was 15 to 18% lower with herbicide mixtures compared with glyphosate alone. Barnyardgrass control with glyphosate plus dicamba was not decreased by drift-reducing nozzles. Carrier volume of > 94 L ha−1 provided greater control of barnyardgrass compared to 47 L ha−1. These results indicate potential of reduced barnyardgrass control with glyphosate plus dicamba.
