Factors influencing the effectiveness of activated carbon used to protect newly-seeded grasses from herbicides

Creator:: Burr, Ronald J.
Abstract:: Previous research has shown that activated carbon is effective in inactivating certain herbicides applied as a preemergence treatment. Studies were conducted in the greenhouse to determine the influence of various factors on the ability of activated carbon to inactivate herbicides applied after carbon application. Field studies were conducted to determine...

The effect of 2,4-D on the respiration rate and ethylene production of Bartlett pears and Red Delicious apples

Creator:: Fechtig, Allen David
Abstract:: After nearly 20 years of commercial use in orchards without apparent tree injury in Oregon and Washington, 2,4-D [(2,4-dichlorophenoxy) acetic acid] was reported in 1970 to cause injury to apple and pear trees in Washington. In the early 1970's, there was widespread concern among growers, researchers, and processors in the...

The effects of N-1-Naphthylphthalamic acid on growth of yellow nutsedge and its control with N-Phosphonomethyl glycine

Creator:: Paller, Enrique C.
Abstract:: Greenhouse and growth chamber experiments were conducted with the following objectives: (a) to study the effects of N-1-naphthylphthalamic acid (naptalam) on shoot and tuber production, rhizome transformation, and growth of yellow nutsedge (Cyperus esculentus L.) plants; (b) to study the effects of N-phosphonomethyl glycine (glyphosate) on nutsedge plants at different...

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...

Foliage applications of terbacil to peppermint (Mentha piperita) and several weed species

Creator:: Radosevich, Steven R.
Abstract:: Several studies were conducted to determine the feasibility of using terbacil (3-tert-butyl-5-chloro-6-methyluracil) postemergence to weeds and peppermint (Mentha piperita L.). Three nonionic surfactants, four nonphytotoxic oils, and a liquid fertilizer were each combined with 0.5 lb ai/A terbacil in 35 gallons of water per acre. Weed species tested include: redroot...

Postemergence herbicides and take-all disease in winter wheat : alterations in the incidence and severity of disease and crop growth

Creator:: Geddens, Ray M.
Abstract:: Eight postemergence herbicides were evaluated to determine their influence on the incidence and severity of take-all disease caused by the fungus Gaeumannomyces graminis var. tritici in winter wheat. Mecoprop ((+)-2-(4-chloro-2-methylphenoxy)propanoic acid), difenzoquat (1,2- dimethyl- 3,5- diphenyl -1H- pyrazolium), dinoseb amine (amine salt of 2-(1-methylpropy1)-4,6-dinitrophenol), and diclofopmethyl (methyl ester of (+)-2-[4-(2,4-dichlorophenoxy)...

Factors affecting selective weedy rye (Secale sp.) control in winter wheat with the herbicide ethiazin

Creator:: Diener, Phillip R.
Abstract:: Weedy rye (Secale spp.) is a weed in the winter-wheat- growing regions in the Pacific Northwest and surrounding regions. Ethiazin (4-amino-6-(1,1-dimethylethyl)-3- (ehtylthio)-1,2,4-triazine-5 (4H)-one) has shown selective control of weedy rye in the cultivar 'Stephens', (Triticum aestivum). Field, greenhouse, and outdoor pot experiments were conducted to determine factors influencing selectivity. Field...

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...
