Volunteer glyphosate-resistant corn (<i>Zea mays</i>) control and competition in glyphosate-resistant cotton (<i>Gossypium hirsutum</i>)( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

<p>Adoption of glyphosate-resistant crops has resulted in increased glyphosate usage and decreased use of residual herbicides thus resulting in weed pressure shifts. Weeds that display multiple-resistance to glyphosate and other herbicide modes of action have become a concern in many parts of the United States. Incorporation of multiple herbicide resistance traits into multiple cropping systems, may facilitate weed resistance to additional herbicides. Furthermore, controlling volunteer crop stands containing multiple herbicide-resistance traits may be problematic in herbicide resistant crops. These volunteer crops will compete with the currently growing crop qualifying them as a weed. Therefore, this research was conducted to determine control options for: failed glyphosate resistant corn stands, and volunteer glyphosate resistant corn stands in glyphosate resistant cotton. Furthermore, research was conducted to determine what densities of glyphosate-resistant corn will cause cotton yield loss and if time of removal of these densities impacts cotton yield loss.</p>

Cattle grazing preferences, animal performance, and harvest management effects among diploid and tetraploid cultivars of annual ryegrass( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

<p>Incremental gains in productivity from new forages are likely to be very small in developed countries like the USA where forage research is highly advanced, thus animals must be used in determining their value. Three experiments were conducted. Experiment I evaluated grazing preference of cattle and its relationship with morphological and chemical characteristics. Treatments were two diploid cultivars Marshall and Gulf and two tetraploid cultivars Maximus and Nelson arranged in a 4 × 4 Latin square design experiment. Animal preference was based on herbage disappearance, the Chesson-Manly index, and animal grazing time. Both herbage disappearance (1400 vs. 890 kg ha<sup>-1</sup>) and Chesson-Manly index (8.1 vs. 5.8%) were greater for tetraploid than diploid cultivars. Experiment II quantified forage and animal response of a tetraploid (Maximus) vs. a diploid (Marshall) annual ryegrass. Three stocking rates (SR), 3.75, 5, or 7.5 animals ha<sup>-1</sup>, were imposed on the two cultivars in a 3 × 2 factorial of a CRD experiment with two replications. Angus cross-bred heifers (initial BW = 240 kg) were used. There was no cultivar effect or any interactions on ADG or herbage mass (HM). Both ADG (1.22 kg d<sup>-1</sup> at low SR to 0.98 kg d<sup>-1</sup> at high SR) and HM (3.8 Mg ha<sup>-1</sup> at low SR to 2.5 Mg ha<sup>-1</sup> at high SR) had a linear response to SR. Experiment III quantified forage production, morphological characteristics, and nutritive value between a tetraploid (Maximus) vs. a diploid (Marshall) annual ryegrass cultivar harvested at three different leaf stages 2-, 3-, and 4-leaves tiller<sup>-1</sup> and two stubble heights 5 and 10 cm. Treatments were arranged in a 3 × 2 × 2 factorial of a RCBD experiment with four replications. In 2011, there was a linear increase in forage harvested from 2-leaf (7.3 Mg DM ha<sup>-1</sup>) to 4-leaf stage (8.8 Mg DM ha<sup>-1</sup>) and in 2012 the response was quadratic with the highest forage harvested at
Somatic culture and induced mutations of giant miscanthus (<i>Miscanthus x giganteus</i>)( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

<p>Exploiting induced genetic diversity through using mutagenesis is particularly important in giant miscanthus (<i>Miscanthus</i> x <i>giganteus</i>; Mxg) due to its restricted genetic variability. Experiments were conducted to develop an efficient <i>in vitro</i> propagation protocol for Mxg, induce mutations in Mxg using a chemical mutagen, and select Mxg <i>in vitro</i> for heat tolerance. To optimize <i>in vitro</i> propagation of Mxg, five explant types [i.e. immature inflorescences, shoot apex (<i>in vitro</i>), shoot apex (greenhouse), leaf explants (<i>in vitro</i>), and leaf explants (greenhouse)] were tested on five media. Shoot forming calli from immature inflorescences, an excellent source of explant in Mxg, grown in media with 13.6 microM 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.44 microM 6-benzylaminopurine (BA) resulted in greatest shoot regeneration rate. Optimization of explant and callus type and media resulted in efficient <i>in vitro</i> proliferation of Mxg and the developed protocol was utilized in consecutive experiments of mutation induction and <i>in vitro</i> selection of Mxg for heat tolerance. Immature inflorescence explants (1-2 mm) were treated with 0.6%, 1.2%, and 1.8% of ethyl methanesulfonate (EMS) whereas the calli (1-2 mm<sup>3</sup>) were treated with 1.2%, 2.4%, and 3.6% of EMS for 90 min. Results of inter simple sequence repeat PCR analysis revealed polymorphisms indicating presence of genetic differences in Mxg putative mutants. <i>In vitro</i> callus cultures (mutagen treated and non-treated) of Mxg subjected to temperature treatments of 45±2°C for 12 hrs or 40±2°C for 7 days were selected for heat tolerance. Assessment results of electrolyte leakage and photosystem II (PS II) efficiency tests indicated a significant difference in percent membrane damage among Mxg clonal lines whereas PSII was weakly affected by the heat stress. The results suggest that in vitro derived Mxg clonal lines may be utilized for f

Evaluation of rapidly growing vegetation on Mississippi roadsides( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Non-point source pollution caused by erosion from road construction poses hazardous environmental effects. Percolation and infiltration of nutrients into groundwater can also be detrimental to the surrounding environment. In addition, annual roadside maintenance budget exceeded $14 million in 2011 for Mississippi. Objectives of this research were to evaluate rapidly established short-statured species in an effort to prevent erosion, combat non-point source pollution, reduce mowing cost, and provide quick cover following propagation. Factors evaluated were rate of establishment, plant cover, and mowing requirement. MDOTs standard seed mix was evaluated along with Penningtons SlopeMaster product and different combinations of selected plant species. Visual and image analysis showed oilseed radish plants established the quickest and provided the most cover. All sod treatments provided instant cover while Penningtons Slopemaster product, as well as mixes that contained bermudagrass or bahiagrass, provided sufficient cover, but not in a timely manner
Postemergence and residual control of glyphosate-resistant palmer amaranth (<i>Amaranthus palmeri</i>) with dicamba( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

<p>On-farm research was conducted in 2011 and 2012 to determine the postemergence and residual control by dicamba of glyphosate-resistant (GR) Palmer amaranth (<i>Amaranthus palmeri</i> S. Wats.). Preemergence dicamba at 0, 0.28, 0.56, and 1.1 kg ae ha<sup>-1</sup> and 0.07 kg ae ha<sup>-1</sup> flumioxazin was applied at 30, 15 and 0 days prior to planting. Postemergence dicamba at 0.28, 0.56, and 1.1 kg ae ha<sup>-1</sup> with and without 0.84 kg ae ha<sup>-1</sup> glyphosate was applied to 5, 10 and 15 cm Palmer amaranth. In addition, a greenhouse experiment was conducted in 2012 to evaluate and confirm the optimum rate for control of Palmer amaranth with a new formulation of dicamba (BAS 18322H). In the greenhouse, dicamba at 0.14, 0.28, 0.56, 1.1, and 2.2 kg ae ha<sup>-1</sup> was applied to 5, 10, and 15 cm Palmer amaranth. </p>
Evaluation of the watchdog weather station to reduce drift from MDOT spray trucks by John D Byrd( Book )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Wind speed data collected with the Spectrum Watchdog Sprayer Station were compared to data recorded with a Young 05103-5 anemometer at the Rodney R. Foil Plant Science Research Center on the Mississippi Sate University campus June and July, 2014 and 2015. The manufacturer’s specifications advertise the Sprayer Station wind speed accuracy for wind speeds less than 12 mph is ±1.1 mph and wind speeds greater thatn 12 mph is ±2.3 mph. While the wind speed data recorded by the Watchdog Sprayer Station followed the same trend as the data recorded with the Young anemometer, variations in wind speed both above and below that recorded by the Young anemometer indicate the Watchdog precision is not sufficiently reliable of the actual wind speed. Wind speed data recorded by the Young anemometer and Watchdog Sprayer Stations were poorly correlated at 0.61 and 0.49 for collection periods in 2014 and 2015, respectively. These data indicate the Watchdog Spryer Station does not measure wind speed with sufficient reliability to provide a MDOT spray truck driver, a true indication when wind speeds are above or below safe parameters for spray applications to avoid drift
