Limited information exists on the impact of addition 28% urea ammonium nitrate (UAN) to 2,4-D, applied preplant (PP) soybean, control multiple-herbicide-resistant (MHR) Canada fleabane. A total five field experiments were conducted over a two-year period (2020, 2021) in southwestern Ontario determine if MHR fleabane with 2,4-D ester PP can be improved by adding UAN spray solution. Glyphosate + ...

The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...

THE TITLE COMPOUND (SYSTEMATIC NAME 3,6-dimethyl-10-p-tolyl-9-oxa-10-phosphaanthracene), C(21)H(19)OP, is a precursor for the preparation of a bidentate xanthene-based ligand, in which the dihedral angle between the toluene ring and the phenoxaphosphine ring system is 83.26 (3)°. The geometry at the P atom is pyramidal, resulting in a longer C-P bond length as compared to the two ring C-P bonds.

Soybean [Glycine max (L.) Merr.] genetic diversity is limited because domesticated soybean has undergone multiple genetic bottlenecks. Its progenitor, the wild soybean [Glycine soja Siebold & Zucc], has not undergone the same intense selection and is much more genetically diverse than domesticated soybean. However, the agronomic importance of diversity in wild soybean is unclear, and its weedy ...

Wastewaters from leather processing are very complex and lead to water pollution if discharged untreated, especially due to its high organic loading. In this study the survival of different plant species in subsurface horizontal flow constructed wetlands receiving tannery wastewater was investigated. Five pilot units were vegetated with Canna indica, Typha latifolia, Phragmites australis, Steno...

Experiments were conducted during the summer of 2002 at the Rice Research and Extension Center, Stuttgart, AR, to evaluate: 1) various timings of sequential applications of imazethapyr at 0.063 lb/acre (4 oz Newpath/acre) in conventional and staleseedbed rice planting systems utilizing Clearfield ‘CL-161’ and 2) the timing of clomazone application at various rates and timings in conventional ri...
