Effect of two methylcarbamates on the toxiciity of isopropyl m-chlorocarbanilate (chlorpropham) to safflower (Carthamus tinctorius L.) and common buckwheat (Fagopyrum esculentum Moench.)

Creator:: Kirkland, Kenneth
Abstract:: Addition of the methylcarbamate compounds p-chlorophenyl N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate (carbaryl) to various herbicides has resulted in reduced rates of degradation. Carbaryl affects the degradation of certain herbicides in both plants and soils while PPG-124 has only been demonstrated to affect degradation in soils. Both these materials are effective...

The influence of herbicide placement in soil on toxicity to emerging seedlings

Creator:: Nishimoto, R. K. (Roy Katsuto), 1944-
Abstract:: Previous research has indicated several soil-applied herbicides are more effective by exposure to emerging shoots than from root uptake. Studies were conducted in the greenhouse and growth chamber to investigate effects of herbicide placement in soil on toxicity to emerging seedlings. In these studies, an inch of treated soil was...

Postemergence herbicides and take-all disease in winter wheat : alterations in the incidence and severity of disease and crop growth

Creator:: Geddens, Ray M.
Abstract:: Eight postemergence herbicides were evaluated to determine their influence on the incidence and severity of take-all disease caused by the fungus Gaeumannomyces graminis var. tritici in winter wheat. Mecoprop ((+)-2-(4-chloro-2-methylphenoxy)propanoic acid), difenzoquat (1,2- dimethyl- 3,5- diphenyl -1H- pyrazolium), dinoseb amine (amine salt of 2-(1-methylpropy1)-4,6-dinitrophenol), and diclofopmethyl (methyl ester of (+)-2-[4-(2,4-dichlorophenoxy)...

The soil persistence and crop selectivity of 3, 6-dichloropicolinic acid

Creator:: Olson, David Lloyd
Abstract:: Field studies were conducted in 1973 and 1974 to determine the soil persistence of the herbicide M-3785 (containing 0.5 lb a.e. Dowco 290 + 2.0 lb a.e. 214D/gallon). under cropping situations. Spring barley (Hordeum distichon L. 'Hannchen') was grown at Corvallis, Oregon and winter wheat (Triticum aestivum L. 'Nugaines.') was...

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...

Interaction of ethofumesate with dry soil

Creator:: McAuliffe, David
Abstract:: Previous studies have shown loss of ethofumesate activity when the herbicide was applied to dry soil (2% w/w moisture content) in both field and greenhouse studies, even when rainfall or irrigation was received within a few days. Laboratory studies were conducted to determine the mechanism for this activity loss. Dry...

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...

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...

Foliar vs. root uptake of the herbicide Hoe 23408 in Italian ryegrass and wild oats

Creator:: West, Geralyn Marie
Abstract:: HOE 23408 [methyl 2-[ 4-( 2, 4- dichlorophenoxy )phenoxy]propanoate] is a herbicide used to selectively-control Italian ryegrass (Lolium muitiflorum Lam.) and wild oats (Avena fatua L.) in wheat. The objective of this research was to compare the relative importance of foliar and root uptake of the herbicide in these two...
