The effect of 2,4'-dinitro-4-trifluoromethyldiphenylether (C-6989) on beans (Phaseolus vulgaris L.) under certain soil and light conditions

Creator:: Pollak, Tomas
Abstract:: Oregon is the largest producer of green beans for processing in the United States. Because the repeated use of a single herbicide may lead to changes in the weed population, build up of residues, and other undesirable factors, a continuous search for new herbicides is taking place. C-6989¹[superscript /] has...

Efficiency of forest vegetation control with herbicides

Creator:: Fredrickson, Edward A.
Abstract:: Selective suppression of crown and root sprouting of non-coniferous cover are the keys to effective forest vegetation management. This study 1) develops insight into mechanisms of controlling root suckering and top regrowth of bear clover (Chamaebatia foliolosa), and develops a broad data base for controlling broad groups of vegetation chemically....

Influence of weed density on efficacy of two soil-applied herbicides

Creator:: Burrill, L. C.
Abstract:: Several studies were conducted to determine the effect of weed density on herbicide efficacy. Diuron [3-(3, 4- dichlorophenyl) -1, 1- dimethylurea] was tested on various densities of Italian ryegrass (Lolium multiflorum Lam. ) under greenhouse and field conditions. Cycloate (S-ethyl N-ethylthiocyclohexanecarbamate) was tested on green foxtail (Setaria viridis (L. )...

Effect of glyphosate when applied to grass and legume seeds or preemergence to bentgrass (Agrostis tenuis Sibth.)

Creator:: Salazar, Luis Carlos
Abstract:: Paraquat (1,11-dimethy1-4,4'-bipyridinium ion) and glyphosate [N (phosphonomethyl)glycine] are herbicides utilized for chemical seedbed preparation in the establishment of grass and legume seed crops. When these herbicides are applied after seeding the crop, seeds which are not protected by a layer of soil could be exposed to the herbicide. Effects of...

Response of downy brome (Bromus tectorum) and Kentucky bluegrass (Pao pratensis) to primisulfuron

Creator:: Hendrickson, Paul E.
Abstract:: Glasshouse and growth-chamber experiments were conducted to evaluate primisulfuron phytotoxicity and the influence of adjuvants on downy brome and Kentucky bluegrass. GR₅₀ (50% growth reduction) values were 0.97 ± 0.57 and 8.07 ± 1.85 g/ha for downy brome and Kentucky bluegrass, respectively. Primisulfuron was applied to downy brome and Kentucky...

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...

Surfactant effects on bromacil and picloram adsorption by Oregon soils

Creator:: Gaynor, John Donald
Abstract:: The physical and chemical properties of soils greatly affect the toxicity of bromacil and picloram. Consequently, a knowledge of the parameters which influence the soil inactivation of these herbicides is necessary to determine proper application rates for good weed control. Enhancement in phytotoxicity with the addition of surfactants or surface...

Some herbicidal properties of 2-chloro 2', 6'-diethyl - N - (methoxymethyl) acetanilide

Creator:: Grandal, Osvaldo Trivelli
Abstract:: Studies were conducted to determine the site of 2-chloro 2', 6'-diethyl-N-(methoxymethyl) acetanilide (CP 50144) toxicity on barnyardgrass (Echinocloa crusgalli (L.) (Beauv.). This was done by means of a technique which used separate layers of treated soil to expose differentially the roots and/or the shoots of barnyardgrass seedlings. Coleoptiles that emerged...
