Extracytoplasmic tubules in leafroll-infected and leafroll-free potato leaf tissue

Journal of Ultrastructure Research, 1980
Unusual clustered tubular structures were noted in cells of both potato leafroll virus (PLRV)-infected and PLRV-free leaf tissue of Solanum tuberosum L., cultivar Russet Burbank. The tubules were most numerous in parenchyma cells in or near the phloem.

Thermotherapy of potato leafroll

American Potato Journal, 1962
Heat treatment at 35 C for 56 days or at 36 C for 39 days completely eliminated leafroll virus from tubers of several potato varieties. Tuber size had little effect on ability to survive the treatment or on the time required for the elimination of leafroll. Tuber losses after heat treatment range from slight to as high as 50%. Heat treatment materially

Purification and characterization of potato leafroll virus

Virology, 1979
Potato leafroll virus (PLRV) was purified from infected potato (Solanum tuberosum L.) with yields of 0.4-0.6 mg/kg of foliage. The virus sedimented as a single component of 127 S. An antiserum prepared against purified virus had a maximum titer of 1:1024 in agar gel double diffusion tests.

Apple, Leafroller Control, 1978

Insecticide and Acaricide Tests, 1979
Abstract Treatments were applied to single-tree plots replicated 5 times using Jonathan, York, Rome, Stayman, and Winesap. These 14-yr-old trees were sprayed to runoff using a Bean high pressure sprayer operating at 600 psi. Cover sprays of Zolone 1 qt (100 gal/acre cone.) were applied at 7-to 10-da intervals on alternate sides from Jun ...

Apple, Leafroller Control, 1975

Insecticide and Acaricide Tests, 1976
Abstract Insecticide treatments applied as full-season, dilute sprays were evaluated in a block of 10-11 year-old trees for leafroller control. The entire block was sprayed with Dikar 6 lb/A + Systox 6E 10 oz/A on April 10, April 17, April 23; Captan 50W 6 lb/A on April 30; Agri-Strep 1.5 lb/A on May 5; Dikar 6 lb/A + Agri-Strep 1.5 lb/A

Apple, Leafroller Control, 1977

Insecticide and Acaricide Tests, 1978
Abstract Four different experiments were run simultaneously in the Brumback Experimental Block, Winchester, VA. Experiment No. 1 was designed to compare the effectiveness of various commercial formulations of Bacillusthuringiensis (Dipel, Thuricide HPSC, Thuricide HPC 1976 material, Thuricide HPC 1977 material). Experiment No. 2 compares

Testing for mild leafroll in Maine

American Potato Journal, 1977
Field and greenhouse readings in Maine together with test plot readings in Florida showed the incidence of potato leafroll virus infection in 10 Kennebec seed lots from south, central and northern Aroostook County to be about 1.2%. When the seed lots were indexed by aphid transmission of the virus toPhysalis floridana Rydb.
