Elm, Control of Elm Leaf Beetle Larvae, Wooster, Ohio, 1990

Insecticide and Acaricide Tests, 1992
Abstract Elm, 2-2.5 m tall, growing in a research plot at the OSU/OARDC campus in Wooster, OH, were used to evaluate insecticides against late instar elm leaf beetle larvae. Elm twigs, 15-25 cm long, infested with 3-10 larvae each, were removed from trees in Columbus, OH, 7 Aug, placed in plastic bags, and immediately transported to ...

ELM frequency feedback control on JET

Nuclear Fusion, 2015
This paper describes the first development and implementation of a closed loop edge localized mode (ELM) frequency controller using gas injection as the actuator. The controller has been extensively used in recent experiments on JET and it has proved to work well at ELM frequencies in the 15–40 Hz range. The controller responds effectively to a variety

Dutch Elm Disease Control: Sanitation Improved by Girdling Infected Elms

Arboriculture & Urban Forestry, 1982
For 5 years three alternative treatments to improve the efficacy of municipal sanitation programs for controlling Dutch elm disease (DED) were compared to the sanitation practice in which one disease survey was made each year and diseased elms were removed in late fall and winter.

Elm bark beetles and Dutch Elm Disease: tests of combined control

Anzeiger für Schädlingskunde, 2001
AbstractThe possibility for the combined control of Ophiostoma novo‐ulmi and Scolytus multistriatus was tested in Italy. Two elm clones [U. pumila×U. minor (clone B) and U. glabra var. pendula grafted onto U. pumila×U. minor pollards (clone A)] were treated by stem injection of different blend or concentrations of fungicides and insecticides.

Elm Bark Beetle Control on American Elm, 1979, 1980

Insecticide and Acaricide Tests, 1985
Abstract American elms were sprayed hydraulically with methoxychlor to determine efficacy against twig-crotch feeding by the smaller European elm bark beetle, a vector of Dutch elm disease (DED). Experiments were conducted in each of 3 cities (Denver, CO; Warren, MI; Shaker Heights, OH).

Formulations for the control of dutch elm disease

Pesticide Science, 1976
AbstractSolutions of methyl benzimidazol‐2‐ylcarbamate (carbendazim, formerly MBC) in dilute hydrochloric, orthophosphoric or hypophosphorous acid and in dilute hydrochloric acid containing methanol (“Lignasan”) and aqueous solutions of 2‐(thiazol‐4‐yl) benzimidazole (thiabendazole) hypophosphite, 8‐hydroxyquinoline (oxine)hydro‐chloride and ...

Control of Elongated Plasma in Presence of ELMs in the JET Tokamak

IEEE Transactions on Nuclear Science, 2011
Tokamaks are the most promising approach for nuclear fusion on earth. They are toroidal machines where the plasma is heated in a ring-shaped vessel and kept away from the vessel by applied magnetic fields. To achieve high performance in tokamaks, plasmas with elongated poloidal cross-section are needed.

Characteristics of pre-ELM structures during ELM control experiment on JET with n  =  2 magnetic perturbations

Nuclear Fusion, 2016
Abstract Radially propagating pre-ELM (edge localized mode) structures in the heat flux profile on the outer divertor have been observed both with and without magnetic perturbations on Joint European Torus. Recently pre-ELM structures over 80% of the ELM cycle are observed.

Dutch Elm Disease Control: Economics of Girdling Diseased Elms to Improve Sanitation Performance

Arboriculture & Urban Forestry, 1982
Early detection and immediate girdling plus prompt removal (within 20 work days) of diseased elms saved more elms at a lower cost than sanitation practices in which diseased elms were just removed promptly or were allowed to remain standing into the dormant season. A 5-year case history demonstrated savings of 25 percent in total cost and an additional

Dutch Elm Disease and Its Control

1979
Excerpt from the report: Dutch elm disease was discovered in Cleveland, Ohio, in 1930 and around the port of New York in 1933. The causal fungus, Ceratocystis ulmi (Buisman) C. Moreau, was introduced on elm-veneer logs imported from Europe. Soon the disease appeared along railroad rights-of-way and at ports of entry.
