Nature of resistance to Verticillium dahliae Kleb. in strains of peppermint (Mentha piperita L.) developed by irradiation

Creator:: Sherrod, Leslie Lynn, 1940-
Abstract:: Verticillium dahliae Kleb. causes a wilt disease of peppermint. Attempts to control the disease by soil fumigation, crop rotation, flaming of stubble, and deep plowing have met with only limited success. Development of resistant varieties through conventional breeding procedures is difficult because commercial peppermint is male-sterile. Several strains of commercial...

Production of polygalacturonase and macerating enzymes by Phoma menthae

Creator:: Melouk, Hassan Aly
Abstract:: The fungus Phoma menthae Strasser causes black lesions and cankers on stems and rhizomes of Mentha piperita L. The purpose of this thesis was to: 1) study the production of polygalacturonase (PG) and macerating enzymes (ME) by P. menthae in vivo and in vitro, 2) study the effects of phenolic...

Selective control of Cirsium arvense (L.) Scop. in Mentha piperita L. with 3,6-dichloropicolinic acid

Creator:: Whitesides, Ralph E.
Abstract:: A series of field experiments was conducted during 1975 and 1976 to examine peppermint tolerance and Canada, thistle response to Dowco 290 (3, 6- dichloropicolinic acid). Peppermint oil yield and Canada thistle density were considered most important in evaluating experimental results. Peppermint tolerance to Dowco 290 was studied in weed-free...

Population dynamics, extraction, and response to nematicide of three plant parasitic nematodes on peppermint (mentha piperita L.)

Creator:: Merrifield, Kathryn J.
Abstract:: The efficiencies of wet sieving/sucrose centrifugation (WS/SC) recovery of Pratylenchus penetrans (59 %), Paratylenchus sp., (80 %), and Criconemella xenoplax (66 %) were established. Baermann funnels (BF) recovered significantly more P. penetrans (p = 0.01) and significantly less (p = 0.01) C. xenoplax than did WS/SC. While densities of P....

Sampling methods, biology and management of the mint flea beetle in central Oregon peppermint

Creator:: Morris, Mark A.
Abstract:: Sampling techniques were evaluated to quantify immature mint flea beetle (MFB), Longitrsus waterhousei Kutschera (Coleoptera: Chrysomelidae), on peppermint (Mentha piperita L.), in central Oregon. During the study period, 1985-1988, soil samples of 350 cm³ were effective for collecting immature MFB. Sifting soil samples through screens was effective for estimating post-feeding...

Trapping and identifying mealybugs in Oregon vineyards

Creator:: Dreves, Amy J., Walton, Vaughn M., and Oregon State University. Extension Service
Abstract:: Mealybugs, a family of soft, oval-bodied pests (Homoptera: Pseudococcidae), are known vectors (carriers) of the grapevine leafroll associated viruses (GLRaVs) of grape. This document gives details on how pheromone traps should be used to ensure optimal catches and early detection.

Biology and host relations of Meteorus comunis (Cresson)

Creator:: West, Kenneth John
Abstract:: Fifteen species of Noctuidae (Lepidoptera) were collected in alfalfa and peppermint in western Oregon. Seven of these species were hosts for the braconid parasitoid Meteorus communis. The most frequently parasitized (percent) species were Agrotis ipsilon (35.3), Dargida procincta (15.0), and Peridroma saucia (6.9). Other species parasitized were Autographa californica (3.8)...
