Available in PDF, EPUB and Kindle. Book excerpt: Volunteer corn (Zea mays L.) is the result of corn kernels remaining in the field following harvest and is a competitive weed in a number of subsequent crops. With widespread adoption of glyphosate-resistant (Gly-R) corn, Gly-R volunteer corn has become a troublesome weed. Little is known about the interference and management of Gly-R volunteer corn in corn. The objectives of this research were to: a) determine the extent of kernels remaining in fields following harvest; b) identify the competitive effects of volunteer corn in corn at densities ranging from 0 to 8 plants m-2; and c) describe the efficacy of glufosinate or imazethapyr + imazapyr to control Gly-R volunteer corn at two densities (1 and 4 plants m-2) and three application heights (10, 20, and 40 cm) in glufosinate-resistant or imidazolinone-tolerant hybrids, respectively. Research was conducted during 2008, 2009, and 2010 at multiple locations throughout central and northeast Missouri. Harvest inefficiencies resulted in kernels remaining in the field at densities ranging from 62,241 to 986,552 kernels ha-1. Volunteer corn was very competitive, reducing row corn leaf nitrogen, stalk diameter, and grain yield with as few as 0.5 plants m-2. Glufosinate applied at all heights, and imazethapyr + imazapyr applied at 10 and 20 cm reduced the impact of volunteer corn and prevented grain yield losses. Overall, harvest inefficiencies will inevitably result in kernel losses, which may result in up to 99 volunteer plants m-2. Producers should minimize the impact of Gly-R volunteer corn by establishing a rotation system with glufosinate-resistant or imidazolinone-tolerant hybrids; other techniques may be needed to eliminate volunteer plants.

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 Control of Volunteer Corn in Enlist Corn and Economics of Herbicide Programs in Conventional and Multiple Herbicide-resistant Soybean Systems Across Nebraska by : Adam Michael Striegel
Download or read book Control of Volunteer Corn in Enlist Corn and Economics of Herbicide Programs in Conventional and Multiple Herbicide-resistant Soybean Systems Across Nebraska written by Adam Michael Striegel and published by . This book was released on 2020 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: With commercialization of multiple herbicide-resistant corn and soybean cultivars, producers have new management options for controlling herbicide-resistant weeds and volunteer corn. Corn-on-corn production systems are common in irrigated fields in southcentral Nebraska which can create issues with volunteer corn management in corn fields. Enlist corn contains a new multiple herbicide-resistant trait providing resistance to 2,4-D choline, glyphosate, and the aryloxyphenoxypropionate (FOPs). Field experiments were conducted in 2018 and 2019 at South Central Agricultural Laboratory near Clay Center, Nebraska with the objective to evaluate ACCase-inhibiting herbicides and herbicide application timing on volunteer corn control, Enlist corn injury, and yield. Glyphosate/glufosinate-resistant corn harvested the year prior was cross-planted at 49,000 seeds ha-1 to mimic volunteer corn in Enlist corn. Application timing of FOP herbicides had no effect on Enlist corn injury or yield, and provided 97-99% control of volunteer corn at 28 d after treatment (DAT). Clethodim and sethoxydim and pinoxaden provided 84-98% and 65-71% control of volunteer corn at 28 DAT, respectively; ii however, resulting in 62-96% Enlist corn injury and 69-98% yield reduction. While all FOP herbicides evaluated did not cause crop injury or yield loss, quizalofop is the only labeled product as of 2020 for control of volunteer corn in Enlist corn. Despite widespread adoption of dicamba/glyphosate-resistant soybean by producers in the United States, economic information comparing herbicide programs in glufosinateresistant and conventional soybean is not available. Field experiments were conducted in 2018 and 2019 at five locations across Nebraska to evaluate weed control, crop safety, gross profit margin, and benefit-cost ratios of herbicide programs with three unique sites of action in multiple herbicide-resistant and conventional soybean. Herbicides applied pre-emergence (PRE) that included provided 85-99% control for all weed species, and 72-96% weed biomass reductions at all locations. Herbicides applied POST provided 93- 99% control for all weed species, and 89-98% weed biomass reduction 28 DAT. For individual site-years, yield was similar for many herbicide programs in herbicideresistant and conventional systems. Gross profit margins and benefit-cost ratios were higher in herbicide-resistant systems than conventional systems, although price premiums for conventional soybean can help compensate increased herbicide costs.
Book Synopsis Integrated Weed Management for Reduced Weed Infestations in Sustainable Cropping Systems by : Rodrigo Werle
Download or read book Integrated Weed Management for Reduced Weed Infestations in Sustainable Cropping Systems written by Rodrigo Werle and published by Frontiers Media SA. This book was released on 2023-10-30 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds pose a major challenge to the sustainability of agricultural production systems, causing significant crop yield, economic and environmental losses. Chemical weed control tactics play a major role in modern weed management, maintaining the productivity of diverse cropping systems, reducing yield losses and facilitating conservation agriculture. However, the over-reliance on chemical weed control has led to shifts in weed communities in agroecosystems which are now becoming dominated by high competitors and herbicide resistance. Thus, weed scientists and practitioners are urged to develop and incorporate innovative and feasible integrated weed management (IWM) systems that can reduce weed infestations and environmental impacts.
