The influence of light, temperature and humidity on the herbicidal activity of bromoxynil (3,5-dibromo-4-hydroxybenzo-nitrile) on Amsinckia intermedia

Creator:: Zimmerman, Martin (Martin Joseph)
Abstract:: The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) to control broadleaf weeds in cereal crops has become widespread. This herbicide has not always performed satisfactorily for reasons which were not clearly evident. The effects of temperature, light and humidity on the herbicidal activity of bromoxynil on coast fiddleneck, Amsinckia intermedia, were studied. Fiddleneck...

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...

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...

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...

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 herbicide HOE 23408; soil persistence, spring wheat cultivar tolerance, and interaction with broadleaf herbicides

Creator:: Ivackovich, Branislav D.
Abstract:: HOE 23408 [ 4-(2' , 4'-dichlorophenoxy)-phenoxy-u-propionic methylester.1 is a promising new compound for control of wild oats and other grass weeds in small grains. Several factors influencing its use for this purpose were investigated. Greenhouse bioassay studies were conducted in 1975 to determine relative persistence of HOE 23408 in four...

Effect of a pre-irrigation period on the activity of ethofumesate applied to dry soil

Creator:: McAuliffe, David
Abstract:: Applications of ethofumesate in Oregon have been observed from previous research and from commercial use to be less effective when applied to dry soils, even if subsequent precipitation occurred within a few days. Two field studies were established in the summer of 1979 using sweet corn (Zea mays L. 'Jubilee')...

The influence of various surfactant-herbicide ratios in three volumes of water on the toxicity of dalapon, paraquat, and terbacil to winter oats (Avena sativa L.)

Creator:: Migchelbrink, Kenneth John
Abstract:: Several studies were conducted to determine if a more consistent predictor of phytotoxicity to winter oats could be obtained with a surfactant-herbicide ratio or a per-unit-volume concentration of surfactant, independent of volume. The herbicides tested were 2,2-dichloropropionic acid (dalapon), 1,1'-dimethyl-4, 4'-bipyridinium (paraquat), and 3-tert-butyl-5-chloro-6-methyluracil (terbacil) with the nonionic surfactant X-77...

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...

Factors influencing barnyardgrass (Echinochloa crus-galli) control with diclofop

Creator:: West, Lynn Douglas
Abstract:: Diclofop (2- [4 -(2, 4-dichlorophenoxy)phenoxy] propanoic acid), formulated as the methyl ester, selectively kills barnyardgrass [Echinochloa crus -galli (L.) Beauv.] in several crops when applied postemergence. Studies were conducted to determine the effect of soil moisture, barnyardgrass age, and site of exposure on control of barnyardgrass with diclofop. Soil moisture...
