Interaction between glyphosate and certain s-triazine herbicides

Creator:: Somabhi, Montien
Abstract:: Investigations were made in the field, greenhouse, growth chamber, and laboratory to: (a) observe the general activity of N- (phosphonomethyl)glycine (glyphosate); (b) determine the extent of its interaction with certain s-triazine herbicides; and (c) find an explanation for such an interaction. Greenhouse and growth chamber studies substantiated other observations that...

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...

Stimulation of plant growth by sub-lethal concentrations of herbicides

Creator:: Wiedman, Steven John
Abstract:: Studies were conducted to determine the extent and nature of sub-lethal effects of herbicides on plant growth. At least one herbicide from each major chemical class of herbicides was evaluated under greenhouse conditions. Oat plants were grown in sand culture to eliminate soil interferences. Herbicides were applied pre-emergence in nutrient...

Microbial degradation of atrazine in soils

Creator:: Skipper, H. D. (Horace D.)
Abstract:: Atrazine is an asymmetrical s-triazine herbicide used pre- and post-emergence for the control of weeds in many crops. Under conditions considered unfavorable for microbial activity, atrazine may persist in soils for extended periods of time. However, the significance of chemical versus microbial degradation is not known. This study was conducted...

Chemical and physical factors in the kinetics of herbicide penetration into plants

Creator:: López, Hernán
Abstract:: Penetration has long been recognized as an important factor in the action of chemicals on plants. The effectiveness of herbicides on such plants as blackberries is often thought to be limited by the failure to obtain adequate penetration through the cuticular barrier. A number of factors, among them relative humidity,...

The physiological effects and fate of dichlobenil (2,6-dichlorobenzonitrile) in an aquatic environment

Creator:: Ogg, Alex Grant, 1941-
Abstract:: The amounts of residual dichlobenil (2,6-dichlorobenzonitrile) in water and hydrosoil were compared periodically following application of the wettable powder and granular formulations of the herbicide to separate ponds at ten pounds of active ingredient per surface acre {0.6 ppmw (parts per million by weight) }. Dichlobenil was measured by electroncapture...

Some herbicidal properties of 2-chloro 2', 6'-diethyl - N - (methoxymethyl) acetanilide

Creator:: Grandal, Osvaldo Trivelli
Abstract:: Studies were conducted to determine the site of 2-chloro 2', 6'-diethyl-N-(methoxymethyl) acetanilide (CP 50144) toxicity on barnyardgrass (Echinocloa crusgalli (L.) (Beauv.). This was done by means of a technique which used separate layers of treated soil to expose differentially the roots and/or the shoots of barnyardgrass seedlings. Coleoptiles that emerged...

Interaction of selected herbicides with soil constituents

Creator:: El-Madhun, Yousef Abdel Wahab
Abstract:: The behavior of six herbicides in soil was studied under controlled laboratory conditions. Sorption of bromacil, chiorotoluron and diuron was assessed by the batch equilibration procedure over a broad range of aqueous phase sorbate concentration. Linear equilibrium sorption constants (K[subscript p]) were slightly higher at 4° C than at 25°...
