Book Synopsis Influence of Application Technology on Foliar Fungicide Efficacy on Cercospora Sojina Infected Soybean by : Shawn Alan Butler
Download or read book Influence of Application Technology on Foliar Fungicide Efficacy on Cercospora Sojina Infected Soybean written by Shawn Alan Butler and published by . This book was released on 2016 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the constant concern with off-target contamination and application technology requirements associated with future herbicide-tolerant crops, the use of drift-reduction nozzle technology (DRT) may increase. The primary objective of this research was to evaluate the effects of coarse droplets generated by drift-reduction nozzles on foliar fungicide efficacy and residual in soybean infected by frogeye leaf spot caused by Cercospora sojina. No differences in disease control, soybean yield, spray retention, and residual when applying Quadris Top SB, a premix of azoxystrobin and difenoconazole, using nozzles that produce either a medium or ultra coarse droplet spectrum were determined. Due to the challenge of timing fungicide applications targeting frogeye leaf spot infections, growers often make applications preventatively, prior to visual infection. Therefore, the second objective was to determine the EC50 of C. sojina isolates collected from trial locations to further investigate the residual control window of azoxystrobin. The effective concentration in which 50% of mycelial growth of resistant isolates tested were inhibited was determined to be 7.44638 [mu]g mL−1 , while the concentration for sensitive isolates was found to be 0.04789 [mu]g mL−1 . The third objective was to determine the effect of droplet size on plant coverage and canopy penetration when making fungicide applications in a commercial setting with increased potential for off-target movement. These studies showed no differences between nozzles producing either medium or ultra coarse droplet spectra when considering frogeye leaf spot control or soybean yield with an application of Quadris Top SB. Coverage analyses determined that applications made with ground self-propelled sprayers deposited 43% more solution in the upper canopy than the lower canopy, but was not effected by droplet spectra. These results indicate that DRT nozzle technology will not have a negative impact on frogeye leaf spot disease control or soybean yield when applying Quadris Top SB. Further studies should be conducted to determine the impact of DRT on other diseases of soybean or alternate crops.
Book Synopsis Fungicides for Field Crops by : Daren Mueller
Download or read book Fungicides for Field Crops written by Daren Mueller and published by . This book was released on 2013 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungicides for Field Crops provides an overview of the current knowledge of fungicides and their use on field crops. This comprehensive book, which includes the contributions of 40 professionals from 20 universities and other organizations, combines past knowledge about fungicides with recent developments in the realm of field crop fungicides. Fungicides for Field Crops highlights the use of fungicides as key tools in the management of important diseases of field crops. Management is presented as a decision-making process--one in which factors as diverse as weather conditions and economics must be considered. Having a more complete understanding of fungicides will inform that decision making and help determine when fungicides should be included as part of a management plan. Parts I, II, and III establish a foundation of knowledge about fungicide use, addressing basic terms and concepts, key factors in decision making, and concerns for fungicide stewardship, respectively. Part IV presents details about using fungicides to manage diseases of 16 field crops. Each crop is treated in a separate section that begins with a discussion of general issues of foliar application and seed treatment and ends with an inclusive table identifying diseases of that crop, including what causes them and how fungicides may be used to treat them. 131 color photographs illustrate disease symptoms and show techniques and enhance the key concepts described in the text.

Book Synopsis The Effect of Mid-season Foliar Fungicide and Insecticide, Applied Alone Or in Combination, on Soybean Yield in Ohio by : Sin Joe Ng
Download or read book The Effect of Mid-season Foliar Fungicide and Insecticide, Applied Alone Or in Combination, on Soybean Yield in Ohio written by Sin Joe Ng and published by . This book was released on 2017 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ohio soybean farmers are very concerned about disease and insect pressure during the midseason that may impact yield. The impact of mid-season management for foliar diseases and insect feeding on grain yield was studied in a series of field experiments. The first objective was to evaluate the effect of mid-season foliar fungicide and insecticide application on soybean yield, applied alone or in combination. A trial was established at 12 on-farm field site-years in Ohio during 2015 and 2016 in a randomized complete block design with four replications per treatment. Fungicide and insecticide treatments included: 1) nontreated control, 2) fungicide alone, 3) insecticide alone, 4) fungicide plus insecticide (tank-mixed), 5) fungicide and insecticide (separate tank), 6) fungicide plus crop oil, 7) insecticide plus crop oil, 8) fungicide, insecticide plus crop oil (tank-mixed). All treatments were applied at R3 growth stage (initial pod development), and data on the percent leaf area affected by foliar diseases and insect defoliation was collected. There was no significant yield response associated with insecticide application due to low insect pressure and low insect defoliation levels at the time of insecticide application at all 12 site-years. However, at the end of the growing season, the number of bean leaf beetles (2-22) and pod injury caused by their feeding (4.1-37%) were high at 4 out of 12 site-years. Fungicide application alone had significantly (P

Book Synopsis Pest Management in Soybean by : L.G. Copping
Download or read book Pest Management in Soybean written by L.G. Copping and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the third in a series of volumes on major tropical and sub-tropical crops. These books aim to review the current state of the art in management of the total spectrum of pests and diseases which affect these crops in each major growing area using a multi-disciplinary approach. Soybean is economically the most important legume in the world. It is nutritious and easily digested, and is one of the richest and cheapest sources of protein. It is currently vital for the sustenance of many people and it will play an integral role in any future attempts to relieve world hunger. Soybean seed contains about 17% of oil and about 63% of meal, half of which is protein. Modern research has developed a variety of uses for soybean oil. It is processed into margarine, shortening, mayonnaise, salad creams and vegetarian cheeses. Industrially it is used in resins, plastics, paints, adhesives, fertilisers, sizing for cloth, linoleum backing, fire extinguishing materials, printing inks and a variety of other products. Soybean meal is a high-protein meat substitute and is used in the developed countries in many processed foods, including baby foods, but mainly as a feed for livestock. Soybean (Glycine max), which evolved from Glycine ussuriensis, a wild legume native to northern China, has been known and used in China since the eleventh century Be. It was introduced into Europe in the eighteenth century and into the United States in 1804 as an ornamental garden plant in Philadelphia.

Book Synopsis Impact of Foliar Fungicides on Yield and Net Returns in Soybeans by : Benjamin Lee Spinks
Download or read book Impact of Foliar Fungicides on Yield and Net Returns in Soybeans written by Benjamin Lee Spinks and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Field studies were conducted in 2003, 2004, and 2005 in the Mississippi delta at 12 locations across common production practices to evaluate the impact of 12 single applications of fungicides at the R3 and R5 growth stage on soybean yield, seed quality, and net returns. Averaged across locations, azoxystrobin alone and mixed with other fungicides increased yields 161 to 343 kg/ha compared to the nontreated control. Fungicide applications made at R3-R4 were more efficacious and resulted in larger yield increases than applications made at R5-R6. Plots treated at the R3-R4 growth stage with 0.11kg ai/ha azoxystrobin alone or in combination with other fungicides yielded 135 kg/ha more than plots treated with the same treatments at the R5-R6 growth stage. Azoxystrobin at 0.11 kg ai/ha and azoxystrobin at 0.11 kg ai/ha + 0.035 kg ai/ha diflubenzuron were the most profitable treatments and increased net returns 23 dollars/ha and 31 dollars/ha, respectively compared to the nontreated control.

Book excerpt: Plants are important for a permanent ecosystem, because in the ecological pyramid plants support all the other living organisms at the base. Very important organization is thought to be the integral process of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants. Accordingly, it is important to obtain more information about the knowledge concerning yield, biomass, and productivity in plants. Soybean is one of the main crops largely contributing to our life, which is thought to be connected to our ecosystem through the above-mentioned integral process. This book focuses on the soybean, and reviews and research concerning the yield, biomass, and productivity of soybean are presented herein. This text updates the book published in 2017. Although there are many difficulties, the main aim of this book is to present a basis for the above-mentioned integral processes of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants (soybean), and to understand what supports this basis and the integral process. It is hoped that this and the preceding book will be essential reads.
