Screening of herbicides for selective weed control in African marigold (Tagetes erecta)
<p>African marigold (Tagetes erecta L.) was screened for tolerance to preemergence and postemergence herbicides. Three preemergence herbicides, pendimethalin, bensulide, and trifluralin, had an acceptable margin of crop safety both in the greenhouse and in the field when applied at one, two, and …

Influence of Penicillium simplicissimum (Oud.) Thom and Penicillium citrinum Thom on growth, chemical composition and root exudation of axenic marigold
Axenic marigold (Tagetes erecta L.) were grown in quartz sand free of organic compounds and one-half strength Hoagland and Arnon nutrient solution plus chelated iron, in individual plant containers, designed for collecting root exudates, inside sterile gnotobiotic flexible plastic isolators. Plant …

Storage of Pine Tree Substrate Influences Plant Growth, Nitrification, and Substrate Properties
… were left fallow and six were planted with marigold (Tagetes erecta L. "Inca Gold") seedlings. Substrate was also collected from select treatments for Most Probable Number assays to estimate density of nitrifying microorganisms, and for chemical and physical property analyses. Pour-through …

The olfactory basis for attraction of the Bollworm helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) to host-plant flowers
… Volatiles collected from flowers of African marigold, Tagetes erecta, and sweet pea, Lathyrus odouratus, were found to elicit electroantennographic (EAG) responses from the antennae of female H. armigera. Compounds active in GC-EAG analyses of T. erecta floral headspace samples, identified by …

Overhead sprinkler irrigation strategies to reduce water and nitrogen loss from container-grown plants
… irrigation on plant growth. In all experiments, Marigold (<u>Tagetes erecta</u> L. 'Apollo') was grown in unamended or sand-amended pine bark in 3.8-liter containers. After saturation, bark was allowed to dry via evapotranspiration to targeted moisture deficits after which irrigation treatments …

Characterization, toxicity, and biological activities of organometallic compounds and peptide nucleic acids for potential use as antimicrobials
Bacterial antibiotic resistance is a globally recognized problem that has prompted extensive research into novel antimicrobial compounds. This dissertation describes research focusing on two types of potential antimicrobial molecules, organometallic compounds (OMC) and peptide nucleic acids (PNA). …

The igneous petrology, thermal history, and genesis of sedimentary rock-hosted Au deposits in the northern Battle Mountain mining district, Nevada
… largest sedimentary rock-hosted Au deposit at Marigold Mine and extends below the redox boundary, where we observe evidence that reactivation of the same fluid pathways through time leads to spatially overprinting hypogene alteration and mineralization styles. Red Dot displays multiple quartz …
