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...

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...

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...

Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

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...

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...

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...

Factors affecting selective weedy rye (Secale sp.) control in winter wheat with the herbicide ethiazin

Creator:: Diener, Phillip R.
Abstract:: Weedy rye (Secale spp.) is a weed in the winter-wheat- growing regions in the Pacific Northwest and surrounding regions. Ethiazin (4-amino-6-(1,1-dimethylethyl)-3- (ehtylthio)-1,2,4-triazine-5 (4H)-one) has shown selective control of weedy rye in the cultivar 'Stephens', (Triticum aestivum). Field, greenhouse, and outdoor pot experiments were conducted to determine factors influencing selectivity. Field...
