Copper Stimulation of Tetrahydrocannabinol and Cannabidiol Production in Hemp ( L.) Is Copper-Type, Dose, and Cultivar Dependent.

Copper (Cu) is an element widely used as a pesticide for the control of plant diseases. Cu is also known to influence a range of plant secondary metabolisms. However, it is not known whether Cu influences the levels of the major metabolites in hemp ( L.

Biologically synthesized zinc and copper oxide nanoparticles using Cannabis sativa L. enhance soybean (Glycine max) defense against fusarium virguliforme.

In this study, zinc and copper oxide nanoparticles (NPs) were synthesized using hemp (Cannabis sativa L.) leaves (ZnONP-HL and CuONP-HL), and their antifungal potential was assessed against Fusarium virguliforme in soybean (Glycine max L.).

Effectiveness of Garlic for the Control of Ixodes scapularis (Acari: Ixodidae) on Residential Properties in Western Connecticut.

We conducted field trials to evaluate the ability of a garlic juice-based product to control or suppress nymphal activity of the blacklegged tick, Ixodes scapularis Say, at residential properties in Connecticut in 2009, 2010, and 2011. The product was applied at a rate of 0.2 g AI/m2.

Expansion of zoonotic babesiosis and reported human cases, Connecticut, 2001-2010.

To document the expansion of human babesiosis in Connecticut, we analyzed reservoir host sera for seroreactivity to Babesia microti Franca and reviewed Connecticut human surveillance case data collected during 2001-2010. Sera from white-footed mice, Peromyscus leucopus Rafinesque, from 10 towns in 5 counties, collected at 4-7-yr periods between 2001 and 2010, were tested for total immunoglobulins. The prevalence of B.

Efficacy and environmental persistence of nootkatone for the control of the blacklegged tick (Acari: Ixodidae) in residential landscapes.

The ability of the plant-derived compound nootkatone to control nymphs of the blacklegged tick, Ixodes scapularis Say, was evaluated at lawn perimeter plots at homes in Lyme disease endemic areas of Connecticut. Three formulations of nootkatone ranging from 0.05 to 0.

Susceptibility of Ixodes scapularis (Acari: Ixodidae) to Metarhizium brunneum F52 (Hypocreales: Clavicipitaceae) using three exposure assays in the laboratory.

An emulsifiable concentrate (EC) and granular (G) formulation of the entomopathogenic fungus, Metarhizium brunneum strain F52 (formerly Metarhizium anisopliae strain F52) were tested against unfed adults and nymphs of Ixodes scapularis Say in the laboratory. Three exposure methods; dip, surface contact, and direct spray application, and three exposure time intervals (3, 30, and 300 min) were used to evaluate the EC formulation. Application rates ranged from 2.

Potential of Tenebrio molitor (Coleoptera: Tenebrionidae) as a bioassay probe for Metarhizium brunneum (Hypocreales: Clavicipitaceae) activity against Ixodes scapularis (Acari: Ixodidae).

The yellow mealworm, Tenebrio molitor L., has been used to indicate qualitatively the presence of entomopathogenic fungi in the soil or as a model for evaluating stress and other factors on fungal activity. Although this beetle appears highly susceptible to many of these fungi, little quantitative information is available on the sensitivity of T.

A formulation to encapsulate nootkatone for tick control.

Nootkatone is a component of grapefruit oil that is toxic to the disease-vectoring tick, Ixodes scapularis Say, but unfortunately causes phytotoxicity to treated plants and has a short residual activity due to volatility. We prepared a lignin-encapsulated nootkatone formulation to compare with a previously used emulsifiable formulation for volatility, plant phytotoxicity, and toxicity to unfed nymphs of I. scapularis.

Evaluation of Metarhizium anisopliae strain F52 (Hypocreales: Clavicipitaceae) for control of Ixodes scapularis (Acari: Ixodidae).

Field efficacy of an emulsifiable concentrate formulation of the entomopathogenic fungus Metarhizium anisopliae strain F52 for the control of Ixodes scapularis nymphs was evaluated at residential sites in northwestern Connecticut in 2007. Two spray applications with two rates, 3.2 x 10(5) and 1.
