The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

Creator:: Harris, James O.
Abstract:: The use of terbacil for weed control was adapted by a high percentage of Oregon peppermint growers soon after its introduction in 1967. To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...

Influence of lime on Italian ryegrass control in winter wheat with five herbicides

Creator:: Ozdilek, Engin
Abstract:: Liming has been shown to increase the activity of certain soil-applied herbicides. One research worker reported improved weed control with diuron after lime had increased soil pH levels. This could be caused by improved competitive ability of the wheat, greater availability of the herbicide, or a combination of the two...

The lateral movement of cycloate as affected by three soil types and four methods of irrigation when applied to the soil by injection incorporation

Creator:: Stanger, Charles Earl, 1929-
Abstract:: Lateral diffusion of S-ethyl N-ethylthiocyclohexanecarbamate (cycloate)¹ is essential for satisfactory weed control with injection type incorporation in sugar beet (Beta vulgaris Linn.) production. Previous field experience with injection incorporation has indicated that sufficient lateral diffusion for satisfactory weed control has not occurred under all field conditions. Researchers who have been...

The influence of light, temperature and humidity on the herbicidal activity of bromoxynil (3,5-dibromo-4-hydroxybenzo-nitrile) on Amsinckia intermedia

Creator:: Zimmerman, Martin (Martin Joseph)
Abstract:: The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) to control broadleaf weeds in cereal crops has become widespread. This herbicide has not always performed satisfactorily for reasons which were not clearly evident. The effects of temperature, light and humidity on the herbicidal activity of bromoxynil on coast fiddleneck, Amsinckia intermedia, were studied. Fiddleneck...

The influence of various surfactant-herbicide ratios in three volumes of water on the toxicity of dalapon, paraquat, and terbacil to winter oats (Avena sativa L.)

Creator:: Migchelbrink, Kenneth John
Abstract:: Several studies were conducted to determine if a more consistent predictor of phytotoxicity to winter oats could be obtained with a surfactant-herbicide ratio or a per-unit-volume concentration of surfactant, independent of volume. The herbicides tested were 2,2-dichloropropionic acid (dalapon), 1,1'-dimethyl-4, 4'-bipyridinium (paraquat), and 3-tert-butyl-5-chloro-6-methyluracil (terbacil) with the nonionic surfactant X-77...

The response of tomatoes to atrazine as affected by magnesium and photoperiod

Creator:: Brenchley, Ronald Glenn
Abstract:: Studies were conducted to determine the nature of the interaction between atrazine (2-chloro-4-ethylamino-6-isopropylaminos- triazine) and magnesium on tomatoes. This interaction was studied under two light regimes: continuous light and a 12-hour photoperiod. Tomato plants were grown in sand cultures at three levels of magnesium fertilization. Four weeks after planting, atrazine...

Abstract:: Volunteer winter wheat (Triticum aestivum 'Daws') severely suppressed growth of fall-planted alfalfa (Medicago sativa (L.) 'Vernal') seedlings. Wheat competition began soon after alfalfa emerged and continued until the first forage harvest the following May. Alfalfa yield at the first cutting was reduced by 1% for each day volunteer wheat was...
