Sodium 2,2-dichloropropionate and sodium 2,2,3-trichloropropionate absorption and translocation in certain vegetable crops and residual activity in soil

Creator:: Laning, Enos Roland
Resource Type:: Dissertation

Some physiological and biochemical aspects of haloxyfop herbicidal activity alone or mixed with dicamba

Creator:: Alvarado, Renan A.
Resource Type:: Dissertation

Interaction of selected herbicides with soil constituents

Creator:: El-Madhun, Yousef Abdel Wahab
Abstract:: The behavior of six herbicides in soil was studied under controlled laboratory conditions. Sorption of bromacil, chiorotoluron and diuron was assessed by the batch equilibration procedure over a broad range of aqueous phase sorbate concentration. Linear equilibrium sorption constants (K[subscript p]) were slightly higher at 4° C than at 25°...

Differential sensitivity of two common groundsel biotypes (Senecio vulgaris L.) to several s-triazine herbicides

Creator:: Radosevich, Steven R.
Abstract:: Studies were initiated to determine the response of two common groundsel biotypes (Senecio vulgaris L. ) to several s-triazine herbicides. Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine (simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)- s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys- triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine (prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio- s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6- methylthio-s-triazine (prometryne). One biotype was much more susceptible than the...

Chemical and physical factors in the kinetics of herbicide penetration into plants

Creator:: López, Hernán
Abstract:: Penetration has long been recognized as an important factor in the action of chemicals on plants. The effectiveness of herbicides on such plants as blackberries is often thought to be limited by the failure to obtain adequate penetration through the cuticular barrier. A number of factors, among them relative humidity,...
Resource Type:: Dissertation

Moisture influences on bromacil distribution in the soil and resultant uptake and phytotoxicity

Creator:: Schreiber, Jonathon Dennis
Resource Type:: Dissertation

Interaction between glyphosate and certain s-triazine herbicides

Creator:: Somabhi, Montien
Abstract:: Investigations were made in the field, greenhouse, growth chamber, and laboratory to: (a) observe the general activity of N- (phosphonomethyl)glycine (glyphosate); (b) determine the extent of its interaction with certain s-triazine herbicides; and (c) find an explanation for such an interaction. Greenhouse and growth chamber studies substantiated other observations that...

How Oregon farmers select and use herbicides on wheat

Creator:: Fine, Richard Ray, 1939-
Abstract:: Questionnaires were used in a survey of Oregon farmers to determine how they select and use herbicides on wheat. Farmer's decisions were evaluated on the basis of their ability to: select the proper herbicide treatment for their weed problem and to make application at the proper time. Questionnaire scores indicated...

Effect of chlorpropham on vegetative and reproductive development in chewings fescue (Festuca rubra L. subsp. commutata Gaud.)

Creator:: Akobundu, I. O.
Abstract:: Experiments were conducted under field and greenhouse conditions to investigate the effects of chlorpropham (isopropyl mchlorocarbanilate) on vegetative and reproductive development in Chewings fescue (Festuca rubra L. subsp. commutata Gaud.) and to determine the time of induction and initiation under natural conditions. Chewings fescue was found to be very susceptible...

The physiological effects and fate of dichlobenil (2,6-dichlorobenzonitrile) in an aquatic environment

Creator:: Ogg, Alex Grant, 1941-
Abstract:: The amounts of residual dichlobenil (2,6-dichlorobenzonitrile) in water and hydrosoil were compared periodically following application of the wettable powder and granular formulations of the herbicide to separate ponds at ten pounds of active ingredient per surface acre {0.6 ppmw (parts per million by weight) }. Dichlobenil was measured by electroncapture...
Resource Type:: Dissertation

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...

A kinetic analysis of herbicide degradation in soil

Creator:: Zimdahl, Robert L.
Resource Type:: Dissertation

Effect of Endothal and certain other selective herbicides on microbial activity in six different soils

Creator:: Au, Frederick Hung Fo
Abstract:: The effect of Endothal (3, 6-endoxyhexahydrophthalic acid), sodium pentachlorophenate (Na-PCP) and TD-47 (di-N, N-dimethylcocoamine salt of Endothal) on the microbial populations, ammonification, nitrification and respiration in six different soils was investigated. It was found that Endothal at 20 and 200 ppm had no adverse effect on the microbial population, ammonification,...
Resource Type:: Dissertation

Studies on the metabolism on n-propyl N, N-di-n-propyl thiolcarbamate in legumes

Creator:: Bourke, John Butts
Abstract:: The absorption, translocation and metabolism of a new herbicide, n-propyl-C¹⁴ N, N-di-n-propyl-thiolcarbamate (PDPC), were studied in both peanut and soybean plants. These studies were carried out on plants of different ages and treated at two rates of application. The residue content of the plants was also determined from germination to...
Resource Type:: Dissertation

The influence of soil temperature and soil placement on the phytotoxic properties of EPTC and other carbamate herbicides

Creator:: Appleby, Arnold P.
Resource Type:: Dissertation

Creator:: Renney, Arthur James
Resource Type:: Dissertation
