This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of dicamba-tolerant (DT) soybeans (Glycine max L. Merr) and cotton (Gossypium hirsutum L) in 2017 provided an additional tool for herbicide resistant weeds management. In the subsequent years, off-target movement of dicamba allegedly caused damage to sensitive crops and vegetation. Possible causes of off-target movement include tank contamination, physical drift, and volatility. Additional products, such as herbicides to control grass, are often added to tank with dicamba, which is used to control broadleaf weeds, to increase the spectrum of control and application efficiency. Dicamba products registered for DT crops require the use of drift reducing agents to mitigate unintended effects to adjacent crops. Sprayers are complex machines with valves, hoses, tanks, and nozzles that can retain herbicide residues and cause symptomology and/or injury to crops if proper cleanout procedures are not performed. Recommended cleanout procedures can be found in dicamba product labels, but there is no information available reporting the effect of tank mixtures or different dicamba formulations on retention of residues. The objective of this research was to: 1) evaluate the dicamba retention of potential tank mixtures with dicamba and drift reducing adjuvants, clethodim as well as tank-cleaning agents on non-DT soybeans, 2) evaluate the cleanout procedures of commonly used dicamba products, on non-DT soybean, and 3) investigate how the rinsate following cleanout procedures of dicamba mixtures affect such as soybean, cotton, tomatoes (Lycopersicon esculentum) and peanuts (Arachis hypogaea L.).
Book Synopsis Evaluation and Development of Effective Tank Cleanout Procedures Following Dicamba Use by : Zachary Andrew Carpenter

This book was released on 2019 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sprayer hygiene and concerns of off-target injury from auxin herbicides have increased in recent years. New auxin tolerant crops have broadened the use patterns of these herbicides. Therefore, experiments were conducted across two locations in Mississippi in 2016, 2017, and 2018 to evaluate sprayer cleanout procedures to aid in dicamba removal. Standard sprayer cleanout consisted of a triple rinse of 10% tank volume, with either a tank cleaner or ammonia added in the second rinse. Samples collected in each rinse step for all treatments were applied to actively growing soybean and dicamba concentration quantified with HPLC. Experiments were conducted to determine if various tank cleaners and ammonia produce visual injury when applied to actively growing soybean and cotton alone and in conjunction with glyphosate. No tank cleaner caused visual injury nor affected plant heights or yield. Furthermore, experiments were conducted to evaluate tank cleaner effectiveness to remove dicamba utilizing the standard cleanout procedure, with increased rinse volumes, sequence of water and tank cleaner rinses, and cleanout effectiveness following durations of idle time from application to cleanout. No tank cleaner provided greater dicamba removal, with all cleaners performing the same as cleanouts utilizing water alone. Increasing rinse volumes did not positively affect dicamba removal compared to 10% rinse volumes. Multiple rinse steps utilizing a tank cleaner or altering the standard cleanout procedure utilizing a water-tank cleaner-water rinse sequence did not result in greater dicamba removal from contaminated sprayer systems. Finally, increases in time between contamination with dicamba and cleanout did not negatively influence dicamba removal using the standard cleanout procedure.
Book Synopsis Tank Contaminant and Residual Effects of Dicamba by : Andy J. Luke
Download or read book Tank Contaminant and Residual Effects of Dicamba written by Andy J. Luke and published by . This book was released on 2017 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction of dicamba-tolerant soybeans (Glycine max L. Merr.) will improve management of increasing populations of herbicide-resistant weeds. However, increased use will lead to risks for damage to susceptible crops such as adjacent soybeans. Research on cleaning commercial spray equipment used to apply dicamba on tolerant soybeans followed by application of other herbicides on sensitive soybeans is needed. Soybean injury and yield following application of spray tank rinsates containing dicamba was studied in 2015 and 2016. Dicamba was applied through two commercial sprayers and spray equipment was subsequently treated with water or one of four cleaning agents (water alone, ammonia, Cleanse® or Erase®). This initial treatment was considered a first rinsate, and was followed by two rinses of water (second and third rinsate). Rinsate solutions were applied on V3 or R1 soybeans. Visible damage was observed at 7 days after treatment (DAT), especially for first rinsates (6 to 16[percent] for V3 treated plants and up to 22[percent] for R1 plants). At 14 DAT, plant height was reduced up to 48 and 33[percent] on V3 and R1 treated soybeans, respectively. Stunting on R1 treated soybeans persisted until the end of the season. First risnates reduced yields up to 11 and 46[percent] for V3 and R1 soybeans respectively, compared to the untreated control. For third rinsates, yields for R1 plants were reduced up to 6[percent], with no effect on V3 plants. Cleaning agents can reduce residues of dicamba in contaminated equipment, but dilution of residues by a triple rinse procedure is most important.
Book Synopsis Effects of Tank Contamination and Impact of Drift-reducing Agents on Weed Control in Response to Dicamba Applications by : Milos Zaric
Download or read book Effects of Tank Contamination and Impact of Drift-reducing Agents on Weed Control in Response to Dicamba Applications written by Milos Zaric and published by . This book was released on 2020 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Availability of dicamba-tolerant (DT) crops from 2017 provided farmers with additional herbicides for weed control management in row crops. However, the technology alike this one has concerns regarding dicamba off-target movement (OTM) causing undesirable effects on sensitive vegetation. Even though dicamba has high water solubility OTM that has often been overlooked when it comes to unintended crop exposure is dicamba tank contamination. Considering the complexity of spraying equipment soybean response may be expected even when small amounts of residues are left in the spray equipment. Typically, the same field spray equipment is used to perform herbicide application through growing season there is a limited knowledge how various postemergence (POST) programs impacts soybean response when found in scenario with dicamba tank contamination and requires additional research. Furthermore, as one way to mitigate OTM potential release of DT crops was followed with registration of various agents also known as drift-reducing agents (DRAs). Increased awareness of both growers and commercial applicators to reduce unintended adjacent crops injury use of labeled DRAs in combination with drift-reduction nozzles represent common practice. Exposure of sensitive crops to sublethal doses of dicamba has been well documented over several years; however, there is limited information available how combination with commonly used DRA's may impact application process and weed control. Considering limitations on available literature the main objective of this research were: 1) evaluate response of non-DT soybean variety when exposed to commonly applied POST herbicide program in combination without or with dicamba as tank-contaminant and 2) evaluate impact of DRAs on weed control in response to dicamba applications. The results of this research expanded knowledge and will help in education in the future management decisions about potential implications associated with common mitigation techniques used with dicamba application as well as helped with understanding how various POST herbicide program affect soybean response.
