A pest management program for variegated cutworm (VC), Peridroma
saucia (Hubner), in Oregon peppermint was developed based on studies
of pheromone trapping, sampling methods, and economic thresholds.
Pheromone traps effectively trapped VC males and were used to
reflect development and oviposition trends. Trap height was linearly
correlated to moth catch...

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...
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....

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...
