Download or read book Evaluation of Crop Tolerance and Weed Control in Corn and Grain Sorghum with Atrazine Replacements written by Jacob Thomas Richburg and published by . This book was released on 2019 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atrazine is a foundational herbicide for weed control in both corn (Zea mays L.) and grain sorghum [Sorghum bicolor (L.) Moench] production. However, studies have shown that while atrazine may be an effective herbicide for preemergence and postemergence control of weeds, it also has risks. The low Koc of atrazine as well as its extensive use over the past 50 years have led it to become the most common groundwater contaminant near agricultural soils. Given these findings, atrazine has faced severe scrutiny while under consideration for reregistration. In the event that atrazine is not reregistered, corn and grain sorghum producers will be forced to seek alternative herbicides for weed control. Therefore, research was conducted in 2017 and 2018 to test the tolerance of corn and grain sorghum to other photosystem II-inhibiting herbicides in combination with other herbicides and also to test weed control with and without atrazine in corn production systems. When applied preemergence in grain sorghum, all PSII herbicides tested reduced grain sorghum yield compared to atrazine treatments. However, when applied postemergence, diuron, fluometuron, linuron, metribuzin, prometryn, propazine, and simazine did not cause grain sorghum to suffer yield loss when compared to atrazine-containing treatments. When applied preemergence in corn, diuron, linuron, metribuzin, and simazine did not cause yield loss to corn when compared to atrazine. However, when applied postemergence in corn, only corn treated with metribuzin and simazine yielded comparable to corn treated with atrazine. Weed control studies displayed that Palmer amaranth (Amaranthus palmeri S. Wats), pitted morningglory (Ipomoea lacunosa L.), and broadleaf signalgrass [Echinochloa crus-galli (L.) P. Beauv.] can all be controlled without atrazine; however, weed density was low in these studies. This research demonstrates some potential PSII-inhibiting herbicides should be further evaluated to assist corn and grain sorghum producers in controlling weeds if atrazine is not reregistered or its use is severely limited.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. Presents previously unpublished information on the discovery, development and marketing of herbicides Includes a vital section on the origin, use, economics and fate of triazine herbicides Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops Establishes best management practice and environmental benefits of use in conservation tillage
Download or read book Variable rate Applications of Soil applied Herbicides in Corn and Grain Sorghum written by Garrison James Gundy and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Field experiments were conducted in 2016 and 2017 across nine locations in Kansas to develop and evaluate a procedure for variable-rate applications (VRA) of soil-applied herbicides in corn and grain sorghum based on soil properties. Soil electrical conductivity (EC) and soil organic matter (SOM) data were collected at each location using a Veris MSP3. Soil EC was correlated to soil texture and herbicide algorithms were developed for two different tank-mixes for corn and for grain sorghum. Three algorithms were evaluated in the field for each tank-mix based only on SOM (alg-SOM), SOM and soil texture (alg-SOMtex), or a flat rate based on the average soil properties for the entire field. Rates for each tank-mix were based on the maximum usage rate (MUR) allowed. When soil variability across a field was adequate, VRA based on algorithms were effective at five of the nine locations. Across these five locations, alg-SOM resulted in the same or better weed control at 8 weeks after treatment (WAT) compared to the flat rate and reduced herbicide use by 12% for both tank-mixes in grain sorghum. Using alg-SOMtex reduced herbicide use by 24% in grain sorghum, but had less weed control at several locations compared to the flat rate. VRA was practical at Morganville, KS in 2017. Both alg-SOM and alg-SOMtex increased the amount of herbicide applied compared to the flat rate, but alg-SOMtex resulted in greater Palmer amaranth control (92%) compared to the flat rate (71%). Separate greenhouse and field experiments were conducted in 2017 to evaluate the activity of soil-applied herbicides on controlling HPPD-inhibitor resistant Palmer amaranth populations. A dose-response greenhouse experiment of soil-applied mesotrione and isoxaflutole was performed using resistant (Stafford County) and susceptible (Riley County) Palmer amaranth populations. Reduced susceptibility was observed with resistant-to-susceptible ratios being 7.2 for mesotrione and 4.1 for isoxaflutole. Field experiments were conducted at two locations in KS with one field having HPPD-resistant (Barton County) and the other HPPD-susceptible (Reno County) Palmer amaranth populations. Treatments were three HPPD-inhibiting herbicides [mesotrione (1⁄4X, 1⁄2X, and 1X = 210 g ha−1), isoxaflutole (1⁄2X and 1X = 105 g ha−1), and bicyclopyrone (1X = 50 g ha-1 and 2X in formulated tank-mix with bromoxynil at 700 and 1400 g ha-1)] in comparison to other soil-applied herbicides commonly used for Palmer amaranth control. HPPD-inhibitor treatments were applied alone and tank-mixed with atrazine (2240 g ha−1). Overall, control of Palmer amaranth was reduced for HPPD-resistant compared to -susceptible populations. All treatments of mesotrione and isoxaflutole at 4 WAT resulted in 81 to 99% control in Reno County, but only 55 to 89% control in Barton County. For mesotrione and isoxaflutole treatments across both sites, Palmer amaranth control at 4 WAT was greater when 1X was applied (89%) compared to 0.5X (81%). Tank-mixing atrazine with mesotrione and isoxaflutole increased Palmer amaranth control from 82 to 88%. Soil-applied HPPD-inhibitors were most effective when applied at field usage rate in combination with atrazine for both populations. When using soil-applied HPPD-inhibitors, management recommendations should be the same regardless of Palmer amaranth population.

Download or read book Weed Management Handbook written by Robert E. L. Naylor and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weed Management Handbook updates the 8th edition of Weed Control Handbook (1990). The change in the title and contents of the book from previous editions reflects both the current emphasis on producing crops in a sustainable and environmentally-friendly manner, and the new weed management challenges presenting themselves. This landmark publication contains cutting edge chapters, each written by acknowledged experts in their fields and carefully drawn together and edited by Professor Robert Naylor, known and respected world-wide for his knowledge of the area. The sequence of chapters included reflects a progression from the biology of weeds, through the underpinning science and technology relating to weed management techniques including herbicides and their application to crops, leading to principles of weed management techniques. Finally a set of relevant case studies describes the main management options available and addresses the challenges of reduced chemical options in many crops. Weed Management Handbook is a vital tool for all those involved in the crop protection / agrochemical industry, including business managers, horticultural and agricultural scientists, plant physiologists, botanists and those studying and teaching BASIS courses. As an important reference guide for undergraduate and postgraduate students studying horticultural and agricultural sciences, plant physiology, botany and crop protection, copies of the book should be available on the shelves of all research establishments and universities where these subjects are studied and taught. Weed Management Handbook is published for the British Crop Protection Council (BCPC) by Blackwell Publishing.
