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...

Non-herbicidal effects of dinoseb on winter wheat yields

Creator:: Valverde, Bernal E.
Abstract:: A series of experiments were conducted from 1983 to 1985 to determine the effects of dinoseb [2-(1-methylpropyl)-4,6-dinitrophenol] on winter wheat (Triticum aestivum L. em Thell) yields. Field trials on dinoseb timing and dinoseb plus supplemental pesticides were established in an effort to elucidate the possible factors involved in the yield...

Factors influencing the herbicidal activity and persistence of isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone in soil

Creator:: Donaldson, Dean Robert
Abstract:: The purpose of this study was to evaluate the activity of Sindone (isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone) under field conditions and to gain information regarding the rate of detoxification of Sindone in soil. A series of trials were established in sugar beet fields in California, Oregon, and Washington. Sindone...

Full Text:: of application. Sugar beet injury was not severe enough to greatly lower yields; however, the yield

Stimulation of plant growth by sub-lethal concentrations of herbicides

Creator:: Wiedman, Steven John
Abstract:: Studies were conducted to determine the extent and nature of sub-lethal effects of herbicides on plant growth. At least one herbicide from each major chemical class of herbicides was evaluated under greenhouse conditions. Oat plants were grown in sand culture to eliminate soil interferences. Herbicides were applied pre-emergence in nutrient...

Herbicidal effectiveness of trifluralin as influenced by methods of incorporation into the soil and depth of weed seed germination

Creator:: Gargano, Don Richard
Abstract:: This study was conducted to compare the effectiveness of four methods of incorporating the herbicide trifluralin into the soil, and to determine the interaction between depth of incorporation of trifluralin and depth of weed seed germination. Field experiments on green and dry peas were established in Oregon and Idaho. Trifluralin,...

Reduction in atrazine toxicity to winter wheat by the growth retardant CCC

Creator:: Kirkland, Kenneth
Resource Type:: Dissertation
Full Text:: affected by CCC treatment was studied. Plants were allowed to take up uniformly ring-labeled 14C atrazine

Competitive effects and control of weeds in winter wheat on the Anatolian Plateau, Turkey

Creator:: Tezel, Cengiz
Abstract:: Wheat is the major crop produced on the Anatolian Plateau of Turkey. Annual weeds cause large yields reductions in the wheat crop. Several formulations of 2, 4-D and mixtures of 2, 4-D and 2,4, 5-T are the only materials currently available for use in Turkey on wheat. The objective of...
Resource Type:: Masters Thesis
Full Text:: , wheat yield increases of 25 to 50% or more are possible by applying herbicides at the optimum time

Influence of soil moisture on the movement of bromacil in soil

Creator:: Ross, Claude Gray
Abstract:: In previous research, bromacil gave good performance when it was applied in early fall with fairly dry soil conditions and before the fall germinating weeds had started growth. On the other hand, if bromacil was applied in late November, December, or January on nearly saturated soil with weeds that had...
Resource Type:: Masters Thesis
Full Text:: soil was not affected by differences in irrigation levels or by the time interval between

The influence of herbicide placement in soil on toxicity to emerging seedlings

Creator:: Nishimoto, R. K. (Roy Katsuto), 1944-
Abstract:: Previous research has indicated several soil-applied herbicides are more effective by exposure to emerging shoots than from root uptake. Studies were conducted in the greenhouse and growth chamber to investigate effects of herbicide placement in soil on toxicity to emerging seedlings. In these studies, an inch of treated soil was...
