The effect of EPTC on barnyard grass

Creator:: Dawson, Jean Howard
Resource Type:: Dissertation
Full Text:: The author with full-grown barnyard grass plant. THE EFFECT OF EPTO ON BARNYARD GRASS

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...

Bioherbicide use of plant defensive compounds in meadowfoam seed meal

Creator:: Intanon, Suphannika
Abstract:: Meadowfoam (Limnanthes alba Hartw. ex Benth) seed meal (MSM), a by-product of meadowfoam oil extraction, has a plant defensive compound known as glucosinolate glucolimnanthin (GLN). Myrosinase enzymes present in soil microbes and meadowfoam seeds can convert GLN to glucosinolate breakdown products (GBPs), which demonstrate herbicidal activity and have the potential...

Studies on the metabolism on n-propyl N, N-di-n-propyl thiolcarbamate in legumes

Creator:: Bourke, John Butts
Abstract:: The absorption, translocation and metabolism of a new herbicide, n-propyl-C¹⁴ N, N-di-n-propyl-thiolcarbamate (PDPC), were studied in both peanut and soybean plants. These studies were carried out on plants of different ages and treated at two rates of application. The residue content of the plants was also determined from germination to...

The effects of CIPC, monuron and 2,4-D herbicides on yield, crude protein and nitrate nitrogen content of four forage-crop species

Creator:: Furtick, William Ralph, 1927-
Resource Type:: Dissertation
Full Text:: plant nutrients Is an indication by Renney (38, p. 14) that tho nitrogen content of cereals Is

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,...

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...

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...
