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...

A kinetic analysis of herbicide degradation in soil

Creator:: Zimdahl, Robert L.
Resource Type:: Dissertation
Full Text:: chemistry. The rate constant for herbicide degradation was obtained by plotting the log of the

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°...

Differential sensitivity of two common groundsel biotypes (Senecio vulgaris L.) to several s-triazine herbicides

Creator:: Radosevich, Steven R.
Abstract:: Studies were initiated to determine the response of two common groundsel biotypes (Senecio vulgaris L. ) to several s-triazine herbicides. Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine (simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)- s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys- triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine (prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio- s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6- methylthio-s-triazine (prometryne). One biotype was much more susceptible than the...

Effect of Endothal and certain other selective herbicides on microbial activity in six different soils

Creator:: Au, Frederick Hung Fo
Abstract:: The effect of Endothal (3, 6-endoxyhexahydrophthalic acid), sodium pentachlorophenate (Na-PCP) and TD-47 (di-N, N-dimethylcocoamine salt of Endothal) on the microbial populations, ammonification, nitrification and respiration in six different soils was investigated. It was found that Endothal at 20 and 200 ppm had no adverse effect on the microbial population, ammonification,...

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,...

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...

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...
