Evaluation of Weed Control and Crop Tolerance With Postemergence Herbicides in Sethoxydim-Tolerant Corn
… and sethoxydim, and method of application, on crop tolerance and bermudagrass (Cynodon dactylon L.) control; to evaluate the effect of sethoxydim in combination with broadleaf herbicides on crop tolerance and bermudagrass control; to evaluate sethoxydim-based herbicide programs for annual grass …

Evaluation of Crop Tolerance and Weed Control in Corn and Grain Sorghum with Atrazine Replacements
… 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, …

Evaluation of Fenclorim Safener for Use in Rice with Group 15 Herbicides
… for Arkansas rice production, but variable crop tolerance has been observed. Additionally, acetochlor at 1,260 g ai ha-1 elicited less rice injury when seeds were treated with a herbicide safener seed treatment of fenclorim at 2.5 g ai kg-1 of seed relative to without the fenclorim seed …

Morphologic and Transcriptomic Response to Weed Pressure in Multiple Maize (Zea mays L.) Selections and Teosinte (Zea mays L. ssp parviglumis) Lines
… <em>indentata</em>) have varying degrees of weed tolerance (ability to maintain yield under weed stress). Maize retains ~30% of its ancestral teosinte’s (<em>Zea mays</em> ssp<em> parviglumis</em>) genetic base. Transcriptomic response to weed pressure in maize and teosinte can lead to …

Identification of differentially expressed genes in the commercially important agarophyte, Gracilaria gracilis, following nitrogen deprivation
… to identify genes that confer enhanced in vivo tolerance to a specific stress. In the current investigation, microarray technology was utilized to identify genes differentially expressed in G. gracilis in response to nitrogen limitation. A total of 39 differentially expressed genes were …

Small non-coding RNA-mediated epigenetic regulation of gene expression and its implications for wheat adaptation to continuous cultivation
… aestivum L.) is one of the most important staple crops worldwide. However, continuous wheat cultivation often leads to yield decline which poses a serious threat to sustainable wheat production. This yield decline is generally attributed to the interaction of abiotic and biotic soil stress factors …

Genomic and Physiological Approaches to Improve Drought Tolerance in Soybean
… stress is a major global constraint for crop production, and improving crop tolerance to drought is of critical importance. Direct selection of drought tolerance among genotypes for yield is limited because of low heritability, polygenic control, epistasis effects, and genotype by …

New Herbicide Strategies for Weed Management in Pumpkin and Soybean and Potato Vine Desiccation
… labeled herbicides. Fluridone resulted in total crop loss following heavy rainfall immediately after planting; less rainfall resulted in transient injury. Acetochlor formulations resulted in significant pumpkin injury (34 to 39%) 14 days after planting. S-metolachlor controlled weeds similar to …

Effects of Organic Soil Amendments on Soil Physiochemical and Crop Physiological Properties of Field Grown Corn (Zea mays) and Soybean (Glycine Max)
… the most critical environmental factor limiting crop production in the US Piedmont. The presence of humic substances in composted organic amendments may increase crop tolerance to water stress through their hormone-like effects on plant metabolism. The objectives of this study were to calculate N …

Identification of chromosomes in hexaploid bread wheat (Triticum aestivum l.) Associated with natural or safener-induced tolerance to halauxifen-methyl
… L.) is one of the most widely cultivated crops globally, and like many other crops, herbicides are utilized for weed control in order to minimize yield loss. While several effective herbicides are labelled for wheat, the application rates and application time frames are often limited in …

Crop response to irrigation with acidic and neutralized, saline mine water
… mine water can be used successfully for crop irrigation, using the waters from the Witwatersrand Goldfields, as water quality references. The study also aimed to investigate the role played by crop tolerance and soil type in mitigating the effects of the mine waters on selected crops. An …
