Persistence of prodiamine and norflurazon herbicides in soil and their activity on alfalfa rotational crops

Creator:: Fischer, Vernon F.
Abstract:: Norflurazon [4-chloro-5-(methylamino)-2(3-(trifluoromethyl) phenyl)- 3(2H)- pyridazinone] and prodiamine (N3, N3-di-n-propy1-2,4- dinitro-6-(trifluoromethyl)-m-phenylenediamine) are two herbicides being considered for weed control in alfalfa. Rotational crops following alfalfa may be sensitive to residues of these herbicides. Studies were conducted in Oregon and Washington to examine the soil persistence and activity of these herbicides on...

Biology and control of tuber oatgrass (Arrhenatherum elatius (L.) presl. var. Bulbosum (willd.) spenn.)

Creator:: Tanphiphat, Karin
Abstract:: Tuber oatgrass (Arrhenatherum elatius (L.) Presl. var. bulbosum (Willd.) Spenn.) is a perennial grass that often becomes a weed problem in Western Oregon. Control efforts using glyphosate often give unsatisfactory results. The effects of several factors on development of tuber oatgrass were investigated. Long days and cool temperatures (16/8h, 20/10C...

An evaluation of weed interference in rice grown on hydromorphic soils in West Africa

Creator:: Diop, Amadou Makhtar
Abstract:: Field, screenhouse, and laboratory experiments were conducted to study weed interference in rice grown on hydromorphic soils at the International Institute of Tropical Agriculture (IITA) at Ibadan, Nigeria. Rice and weeds emerged at the same time, 1 week after planting. Weed dry weight was significantly reduced when the crop was...
Resource Type:: Dissertation
Full Text:: experimental approach and analysis of plant-plant interactions. I am also grateful to J. E. Hill, University

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...
Resource Type:: Masters Thesis
Full Text:: reduced yield, regardless of dinoseb application, because of lodging. Methyl bromide increased plant

Cyperus esculentus control with glyphosate : time of application and addition of ammonium sulfate

Creator:: Costa, Jaime
Abstract:: Cyperus esculentus L. var. esculentus is a serious weed problem in northwest Spain. Long-term control from glyphosate and other herbicides has been inconsistent. Field, greenhouse, and laboratory studies were conducted on factors influencing the activity of glyphosate on C. esculentus. In field studies, glyphosate controlled foliage growth at most growth...
Resource Type:: Dissertation
Full Text:: , but did not affect total absorption. Gly- phosate translocation from treated portions of the plant

Sethoxydim herbicide in red fescue and bentgrass : levels and mechanisms of selectivity

Creator:: Butler, J. Hugh B.
Abstract:: The herbicide rate required to reduce growth by 50% (GR₅₀) of 11 cultivars of red fesue (Festuca rubra L. and F. rubra ssp. commutata) and for four cultivars of bentgrass (Agrostis tenuis Sibth. and A. stolonifera L. var. palustris) to sethoxydim (2-[1-(ethoxyimino) butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one) was determined in greenhouse and laboratory experiments....
Resource Type:: Dissertation
Full Text:: 2.1 Movement of 14 C sethwdim applied to soybean. 2.5 nM of C sethoxydim applied to each plant

Apoplastic distribution of atrazine and glyphosate in intact sunflower leaves

Creator:: Jachetta, John Joseph
Abstract:: Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)- 6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)- glycine], the naturally occurring apoplastic leaf solutes, and the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate) were compared. Aliquots of sap were expressed from intact sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4 bars. Three distinct fractions were detected...

Tobacco rattle virus : weed hosts, diagnosis, characterization, purification, and interaction with potato virus X

Creator:: Locatelli, Eduardo Atilio
Abstract:: A series of studies was conducted to determine the presence of tobacco rattle virus (TRV), potato virus X (PVX), and other viruses in wild plants and to evaluate the efficacy of the detection methods; to characterize and purify an isolate of TRV; and to study the interaction between TRV and...
