Non-herbicidal effects of dinoseb on winter wheat yields

Creator:: Valverde, Bernal E.
Abstract:: A series of experiments were conducted from 1983 to 1985 to determine the effects of dinoseb [2-(1-methylpropyl)-4,6-dinitrophenol] on winter wheat (Triticum aestivum L. em Thell) yields. Field trials on dinoseb timing and dinoseb plus supplemental pesticides were established in an effort to elucidate the possible factors involved in the yield...

Factors influencing metribuzin use in strip-planted wheat

Creator:: Zeghida, Ali
Abstract:: Equipment for strip-till planting is under development in wheat-fallow rotations in the Columbia Basin of Oregon. This involves the absence of tillage during the fallow season. At planting time, the strip-till planter creates a narrow band into which the wheat seed is placed. The area between the rows is undisturbed...

Selective control of volunteer wheat (Triticum aestivum (L.) em. Thell.) in new seedlings of alfalfa (Medicago sativa L.) with fluazifop-butyl and sethoxydim

Creator:: Ott, Pablo
Abstract:: Volunteer winter wheat (Triticum aestivum 'Daws') severely suppressed growth of fall-planted alfalfa (Medicago sativa (L.) 'Vernal') seedlings. Wheat competition began soon after alfalfa emerged and continued until the first forage harvest the following May. Alfalfa yield at the first cutting was reduced by 1% for each day volunteer wheat was...

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 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...

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...

The response of tomatoes to atrazine as affected by magnesium and photoperiod

Creator:: Brenchley, Ronald Glenn
Abstract:: Studies were conducted to determine the nature of the interaction between atrazine (2-chloro-4-ethylamino-6-isopropylaminos- triazine) and magnesium on tomatoes. This interaction was studied under two light regimes: continuous light and a 12-hour photoperiod. Tomato plants were grown in sand cultures at three levels of magnesium fertilization. Four weeks after planting, atrazine...

Behavior of metribuzin and ethylmetribuzin in soil

Creator:: Peek, Daniel C.
Abstract:: The behavior of metribuzin [4-amino-6-(1,1- dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] and ethyl-metribuzin (4-amino-6-(1,1-dimethylethyl)-3- (ethylthio)-1,2,4-triazin-5(4H)-one] in soil was studied to determine if differences in herbicide behavior in soil could explain (a) the inconsistent herbicidal activity of these chemicals and (b) the greater activity of metribuzin, as compared to ethyl-metribuzin. Metribuzin had higher activity than ethyl-metribuzin...
