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...
Fertilization is part of the overall management of peppermint and spearmint that includes planting of disease-resistant varieties, selection of appropriate soils, irrigation, timely harvest, and control of diseases, weeds, insects, and nematodes. Other OSU publications cover pest control on peppermint (see page 4). Crop response to fertilizer may differ with...
Adequate soil moisture is one of the most important factors in tree growth and production. The amount of irrigation needed varies greatly according to soil type and depth, season, weather, and tree size.

Several aspects affecting population trends and overwintering of Neoseiulus
fallacis (Garman) on peppermint were examined. Neoseiulus fallacis was the most
abundant phytoseiid predator mite found in peppermint surveys throughout the western U.S. Results of pesticide exclusion and cage studies showed that N. fallacis controlled Tetranychus urticae (Koch) on peppermint in...
Improved water use efficiencies in irrigated agriculture are necessary to assist in coping with the accelerating demand and economic competition for the world's fresh water supply and increasing ecological concerns. This will likely rely in part on optimum irrigation, which implies regulated deficit irrigation. While conventional irrigation management is intended...
Since publication of the Oregon State University–University of California report on Klamath Basin water allocation,1 the Bureau of Reclamation (BOR) and Klamath Water Users Association (KWUA) initiated a pilot project to
compensate growers who agree to withhold irrigation from 12,000 acres of Project lands. This “Pilot Water Bank,” in place...
