Studies on the Subterranean Activity of Laricobius spp. (Coleoptera: Derodontidae) using 3D X-ray Analysis and Three Imidacloprid Soil Application Techniques
… for HWA management, is typically applied to the soil below HWA infested trees and breaks down into several metabolites, including two with insecticidal properties; 5-hydroxy imidacloprid (5H-IMI) and imidacloprid-olefin (IMI-OLE). Imidacloprid-olefin is known to be up to 14 times as lethal to HWA …

Flea Beetle Populations and Their Management on Vegetables in Virginia
… of various insecticides was also evaluated; soil application of the systemic neonicotinoid dinotefuran had the fewest beetles, the least amount of leaf defoliation, and the highest yield in cabbage and eggplant. Lastly, deltamethrin-incorporated mesh row covers were evaluated and shown to …

Wastewater renovation with soil depth as influenced by additional treatment of septic tank effluent
Many soils are marginally suited for installation of on-site wastewater disposal systems. With soil limitations, additional wastewater treatment prior to soil application may allow for a reduction in soil depth. Undisturbed 20-cm-diameter soil columns (fine loamy, mixed, mesic Typic Hapludult), in …

Fate and effects of pulp mill effluent solids in the soil environment
… as current landfill space is limited. Land application has been used for many years as a means of disposal of pulp mill wastes. While most studies investigating land application of pulp mill effluent solids have concluded that the risk posed to the environment is low, few have investigated …

Evaluation of Safening Effects to Herbicides Conferred via Insecticide Seed Treatments in Soybean (Glycine max) and Grain Sorghum (Sorghum bicolor)
… for a number of years. Research has shown that applications of some organophosphate insecticides at planting can reduce cotton injury following applications of the soil-applied herbicide clomazone. Additionally, recent research has shown that, when applied as seed treatments prior to planting, …

The ecological impacts of a novel nematode control agent
Plant-parasitic nematodes are prevalent in many soils and impose an economic burden worldwide on agriculture, through yield reductions and cost of control. There is a prominent need for the development and implementation of sustainable control mechanisms, to reduce the widespread use of hazardous …

Field and laboratory investigations on the efficacy, selectivity, and action of the herbicide clomazone
… several broadleaf weeds. Control from preplant applications of clomazone was not adequate. Preemergence and preplant incorporated applications of clomazone were compared in conventionally-tilled soybeans. Clomazone efficacy at two depths of incorporation was also investigated. Clomazone applied …

Corn response to long-term application of CuSO₄, ZnSO₄ and Cu-enriched pig manure
… to investigate the effects of Cu and Zn in soils and corn (Zea mays L.). The first field study consisted of continuing a longterm field experiment which was established in 1967 to evaluate corn response and changes in a Davidson clay loam soil to yearly additions of Cu and Zn sulfates. In …

Quantifying Greenhouse Gas Emissions and Ammonia Volatilization from Soil Amended with Excreta from Ruminants Fed Alternative Forage-based Diets
… in the animal and reduce gas emissions from soil receiving excreta. The objective of the study was to determine if soil receiving urine or manure from sheep fed forage diets supplemented with condensed tannin or polyphenolic-containing legumes would decrease N gas emissions. Two field trials …

Copper adsorption/desorption characteristics on copper amended soils
… to determine Cu availability of three Virginia soils amended with Cu as either Cu-rich pig manure or CuSO₄ with the same Cu content as that in manure. The study also assessed the capability of Mehlich-3 to estimate deficient and toxic Cu levels in soil. Application of Cu as manure or CuSO₄ did …

Chemically Induced Phytoextraction of Lead (Pb) Contaminated Soil by Switchgrass (Panicum virgatum L.)
<p>Soils contaminated with lead (Pb) from human activities including industrial byproducts create an environmental and human health risk. Phytoextraction through chemical acquisition of Pb in soils offer a potentially cost effective and ecologically driven approach to remediation. Switchgrass …

The fate and distribution of phosphate applied to Davidson clay loam
… and availability of applied and native P in this soil. A further aim of the investigation was to elucidate mechanisms controlling the availability of P to plants in Davidson clay loam that was limed to several pH values. These objectives were accomplished by a study of orchard grass yield data …

Imaging the distribution of agrochemicals in plants by MALDI-MSI.
… target site within the organism after spray or soil application. This is influenced by a range of physiological and environmental factors. One such factor is uptake into foliar tissue and roots and subsequent movement through the plant. Uptake and translocation (and metabolism) can affect the …

Fracture Characteristics of Concretes and Cement-Stabilized Soil
Application of fracture mechanics to the cracking and failure of concrete under stress has been receiving considerable attention. Most of these investigations have been directed towards the determination of the critical stress intensity factor or fracture toughness of concrete, mortar, or cement …
