Creator:: Gargano, Don Richard
Abstract:: This study was conducted to compare the effectiveness of four methods of incorporating the herbicide trifluralin into the soil, and to determine the interaction between depth of incorporation of trifluralin and depth of weed seed germination. Field experiments on green and dry peas were established in Oregon and Idaho. Trifluralin,...

Abstract:: The use of CIPC (isopropyl N-(3-chlorophenyl) carbamate) to control dodder (Cuscuta spp.) in alfalfa is an established practice. A rate of six pounds per acre applied to moist soil has given good dodder control lasting from four to six weeks. The purpose of this study was to determine the effect...

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...

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...

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...

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...

Abstract:: Atrazine, atratone and ametryne are asymmetric s-triazine herbicides used pre- and post-emergence on many crops. Under conditions unfavorable for microbial activity, these compounds may persist in the soil for long periods of time. This study was conducted to determine the influence of the soil microflora upon atrazine, atratone and ametryne...
