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...

Response of Cuscuta campestris and Cuscuta indecora to glyphosate applied after attachment to alfalfa (Medicago sativa)

Creator:: Fessehaie, Rezene
Abstract:: The response to glyphosate [N-(phosphonomethyl) glycine] of two dodder species Cuscuta campestris Yuncker (field dodder) and Cuscuta indecora Chiosy (largeseed dodder) parasitizing alfalfa (Medicago sativa L.) was compared. In the absence of glyphosate, alfalfa was killed or severely injured by parasitism from uncontrolled dodder. Results of field experiments in which...

A taxonomic study of bitterbrush (Purshia tridentata (Pursh) DC.) in Oregon

Creator:: Alderfer, Jean Marie
Abstract:: Extensive morphological and growth habit variations have been reported for bitterbrush (Purshia tridentata), a widespread western shrub frequently used in range revegetation projects. Hybridization of this species occurs with cliffrose (Cowania stansburiana) at the point of their overlapping range in Utah and is believed to be responsible for expression of...

Hydroxyindole-O-methyltransferase (HIOMT) activity in the pineal of chinook salmon (Oncorhynchus tshawytscha)

Creator:: Birks, Eric K.
Abstract:: C-methyltransferase (HIOMT) in chinook salmon (Oncorhynchus tshawytscha). Various body tissues, as well as several morphological brain divisions were tested for the presence of HIOMT. Activity was found in the retina, the dorsal portion of the diencephalon, and in the pineal gland of chinook. However, the activity was significantly higher in...

A revision of the black grass bug genus Irbisia Reuter (Heteroptera:Miridae)

Creator:: Schwartz, Michael David
Abstract:: The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

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...

Effect of cereal companion crops on the establishment of red fescue (Festuca rubra L.) for seed production

Creator:: Chastain, Thomas G.
Abstract:: Some perennial grass seed crops such as red fescue (Festuca rubra L.) do not produce a profitable seed crop during the first growing season. The present establishment method in Oregon for red fescue seed crops generally entails spring planting which does not satisfy vernalization requirements for seed production in the...
