Formulations for the control of dutch elm disease
Pesticide Science, 1976AbstractSolutions 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 ...

Elm bark beetles and Dutch Elm Disease: tests of combined control
Anzeiger für Schädlingskunde, 2001AbstractThe 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, 1985Abstract 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).

Control of Elongated Plasma in Presence of ELMs in the JET Tokamak
IEEE Transactions on Nuclear Science, 2011Tokamaks 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.

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, 1982Early 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

Chemical Mixtures for Control of Winged Elm
Weed Science, 1975Various growth regulators, carrier systems, and ammonium thiocyanate (NH4SCN) additions in combination with herbicide mixtures were evaluated for their foliar phytotoxicity to winged elm (Ulmus alataMichx.). Silvex [2-(2,4,5-trichlorophenoxy)propionic acid] and 2,4,5-T [(2,4,5-trichlorophenoxy)acetic acid] were more effective than the dichlorophenoxy ...

Dutch Elm Disease and Its Control
1979Excerpt 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.
