An economic analysis of alternative herbicide practices

Creator:: Coulston, Lane Edward
Abstract:: There is a critical lack of economic information in the area of chemical weed control. This paper is intended to stimulate study in this area. The objective is to develop a method of economic analysis of alternative herbicide practices. The data used were taken from a Druchamp winter wheat trial...

Efficiency of forest vegetation control with herbicides

Creator:: Fredrickson, Edward A.
Abstract:: Selective suppression of crown and root sprouting of non-coniferous cover are the keys to effective forest vegetation management. This study 1) develops insight into mechanisms of controlling root suckering and top regrowth of bear clover (Chamaebatia foliolosa), and develops a broad data base for controlling broad groups of vegetation chemically....

Surfactant effects on bromacil and picloram adsorption by Oregon soils

Creator:: Gaynor, John Donald
Abstract:: The physical and chemical properties of soils greatly affect the toxicity of bromacil and picloram. Consequently, a knowledge of the parameters which influence the soil inactivation of these herbicides is necessary to determine proper application rates for good weed control. Enhancement in phytotoxicity with the addition of surfactants or surface...

Effects of three herbicides on yields of five cultivars of winter wheat (Triticum aestivum L. em Thell)

Creator:: Yahyaoui, Amor
Abstract:: With the development of new selective herbicides and the frequent change in commercial wheat cultivars, information is needed as to the possible interaction between cultivars and herbicides. The responses of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1- dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propanoate...

Annual bluegrass (Poa annua L.) control with ethofumesate during turfgrass establishment

Creator:: Wieneche, David L.
Abstract:: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of...
