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...

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...

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,...

The influence of magnesium on the toxicity of atrazine

Creator:: Brenchley, Ronald Glenn
Abstract:: Atrazine is an asymmetrical s-triazine herbicide used pre- and post emergence for weed control in many crops. Triazine herbicides have been used in the Pacific-Northwest for weed control in orchard crops. Under certain conditions where trees were grown in nutrient deficient areas, it was noted that toxic symptoms due to...

The influence of soil moisture and method of application on the movement of the herbicide EPTC in soil

Creator:: Omid, Ahmad
Resource Type:: Masters Thesis

Microbial degradation of atrazine in soils

Creator:: Skipper, H. D. (Horace D.)
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...

The effect of EPTC on barnyard grass

Creator:: Dawson, Jean Howard
Resource Type:: Dissertation
Full Text:: The Effect of EPTC on Barnyard Grass THE EFFECT OF EPTC

Herbicidal effectiveness of trifluralin as influenced by methods of incorporation into the soil and depth of weed seed germination

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,...
Resource Type:: Masters Thesis
