Effect of two methylcarbamates on the toxiciity of isopropyl m-chlorocarbanilate (chlorpropham) to safflower (Carthamus tinctorius L.) and common buckwheat (Fagopyrum esculentum Moench.)

Creator:: Kirkland, Kenneth
Abstract:: Addition of the methylcarbamate compounds p-chlorophenyl N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate (carbaryl) to various herbicides has resulted in reduced rates of degradation. Carbaryl affects the degradation of certain herbicides in both plants and soils while PPG-124 has only been demonstrated to affect degradation in soils. Both these materials are effective...

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...

Interference of annual weeds in seedling alfalfa

Creator:: Fischer, Albert J.
Abstract:: The interference of barnyardgrass (Echinochloa crusgalli), pigweed (Amaranthus retroflexus),downy brome (Bromus tectorum),and tumble mustard (Sisymbrium altissimum) with alfalfa was studied. Alfalfa was seeded with each of the four weeds on August 14 and September 15, 1981, and on April 13, 1982. Alfalfa also was seeded on August 27, 1981, with...

Factors influencing wild oat control with N-benzoyl-N-(3,4-dichlorophenyl) alanine (SD 30053)

Creator:: Colbert, Donald Robert
Abstract:: Studies were conducted in 1969 and 1970 to evaluate the effectiveness of an experimental herbicide, SD 30053 (alanine, N-benzoyl-N-(3, 4-dichlorophenyl)-, ethyl ester), for wild oat (Avena fatua L.) control in winter cereals. The 1969 field studies showed that postemergence applications of SD 30053 were effective in controlling wild oats. Wild...

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 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...

Degradation of the herbicide EPTC in three Willamette Valley soils

Creator:: Coleman, Quentin Charles
Abstract:: EPIC (S-ethyl dipropylthiocarbamate) is a selective herbicide which controls some annual grasses, annual broadleaves, and perennial grasses when incorporated into the soil before planting. In the last few years, reports have been received of certain fields in the Willamette Valley of Oregon in which EPIC was no longer effective. Preliminary...

Studies of napropamide decomposition on the soil surface

Creator:: Apley, Kathryn Lynne
Abstract:: Napropamide [2-(alpha-naphthoxyl)-N,N-diethylpropionamide], a preemergence herbicide, is widely used in the United States on a variety of tree fruits, nut crops, vegetables, and mint for annual grass and broadleaf weed control. When napropamide has been left on the soil surface without incorporation through irrigation or mechanical means, inconsistent results have been...

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...

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...
