Gamma ray irradiation on Swiss cheese estates (): growth, development, and variation.

Purpose: Swiss Cheese () is an ornamental plant valued for its exotic leaves with openings and for the variety of colors. The technique of controlled exposure to gamma radiation was investigated to induce variegation (color change) in the leaves of this plant.

Materials And Methods: cuttings were irradiated with different doses of radiation with Co gamma rays (0, 1, 5, 10, 15, and 20 Gy) and evaluated for size, color, health, and growth.

The impact of fast-growing eucalypt plantations on C emissions in tropical soil: effect of belowground and aboveground C inputs.

Planted forest soils can have great potential for CO-C sequestration, mainly due to belowground C inputs, which impact deep soil C (DSC) accumulation. However, there are still gaps in understanding the CO emission dynamics in eucalypt plantations. Therefore, we used isotopic techniques to investigate the dynamics of the soil surface CO-C flux and CO-C concentration with depth for a eucalypt plantation influenced by different C inputs (above- and belowground).

Diuron, hexazinone, and sulfometuron-methyl applied alone and in mixture in soils: Distribution of extractable residue, bound residue, biodegradation, and mineralization.

Biodegradation studies of herbicides applied to the soil alone and in a mixture are required since herbicides are often used in combinations to control weeds. When herbicides are applied in mixtures, interactions may affect their environmental fate. Thus, the objective of this study was to evaluate the distribution of extractable residue, bound residue, biodegradation, and mineralization of diuron, hexazinone, and sulfometuron-methyl when applied alone and in a mixture in two agricultural soils.

Indaziflam sorption-desorption and its three metabolites from biochars- and their raw feedstock-amended agricultural soils using radiometric technique.

This study aimed to characterize the effect of amending soils with biochars derived from soybean residues, sugarcane bagasse, and wood chips on the sorption-desorption of indaziflam and indaziflam-triazinediamine (FDAT), indaziflam-triazine-indanone (ITI), and indaziflam-carboxylic acid (ICA) metabolites applied to soils from three Midwestern U.S. states, a silt loam and a silty clay loam.

Cow bonechar decreases indaziflam pre-emergence herbicidal activity in tropical soil.

The addition of carbonaceous material such as cow bonechar to the soil can affect the availability of applied pre-emergent herbicides such as indaziflam. However, how cow bonechar affects the bioavailability of indaziflam is not yet known. The aim of this study was to evaluate the effect of cow bonechar on herbicidal activity of indaziflam on weeds in a tropical soil.

Phytoremediation of quinclorac and tebuthiuron-polluted soil by green manure plants.

Quinclorac and tebuthiuron are residual herbicides that may remain in the soil longer than for the cropping season. The objective of this research was to evaluate the use of green manure plants to remediate soils treated with quinclorac and tebuthiuron. Soils were separately treated with C-quinclorac and C-tebuthiuron at 266.
