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...

Factors influencing the effectiveness of activated carbon used to protect newly-seeded grasses from herbicides

Creator:: Burr, Ronald J.
Abstract:: Previous research has shown that activated carbon is effective in inactivating certain herbicides applied as a preemergence treatment. Studies were conducted in the greenhouse to determine the influence of various factors on the ability of activated carbon to inactivate herbicides applied after carbon application. Field studies were conducted to determine...

Selective control of Cirsium arvense (L.) Scop. in Mentha piperita L. with 3,6-dichloropicolinic acid

Creator:: Whitesides, Ralph E.
Abstract:: A series of field experiments was conducted during 1975 and 1976 to examine peppermint tolerance and Canada, thistle response to Dowco 290 (3, 6- dichloropicolinic acid). Peppermint oil yield and Canada thistle density were considered most important in evaluating experimental results. Peppermint tolerance to Dowco 290 was studied in weed-free...

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...

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....

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...

Asulam in western Oregon pastures : broadleaf dock control and tolerance of important grass and legume species

Creator:: Majek, Bradley A.
Abstract:: In previous research in Europe, asulam (methyl sulfanilylcarbamate) was found to be a potentially useful herbicide for controlling broadleaf dock Rumex obtusifolius L. ) in permanent pastures. Asulam was also reported to have a low margin of safety when used on common pasture species. Field studies were conducted in western...
