Incinerated sewage sludge use as a soil amendment for sweet corn (Zea mays L.)

Creator:: Mellbye, Mark Edward
Abstract:: Field and greenhouse experiments were conducted to determine the suitability of using incinerated sewage sludge ash as a soil amendment for sweet corn production on Willamette silt loam. In 1977, field plots were treated with 0, 11, 22, and 43 mt/ha of ash containing lime, in factorial combination with a...

Improvement of biological control agents : laboratory selection for fast larval development in the convergent lady beetle, Hippodamia convergens guerin-Méneville (Coleoptera: Coccinellidae)

Creator:: Rodriguez-Saona, Cesar Ramiro
Abstract:: Hippodamia convergens Guerin-Meneville was selected for rapid development through five generations at four constant temperatures (18, 22, 26, and 30°C). Two levels of selection were used: intense and moderate. Differences in developmental rate, survivorship, live adult weight, aphid consumption, adult longevity, and fecundity were measured for both groups and an...

The simultaneous expression of metal tolerance and antibiotic resistance by bacteria from drinking water systems

Creator:: Calomiris, Jon James
Abstract:: Previous studies of six Oregon public water supply systems revealed that greater proportions of the standard plate count (SPC) bacteria from distribution waters were multiple antibiotic resistant (MAR) compared to isolates from the corresponding source raw waters. In the present study, two of these water systems were examined further to...

The Ecology and Epidemiology of Xanthomonas hortorum pv. carotae in Central Oregon Carrot Seed Production Systems

Creator:: Baldino, Katelyn D.
Abstract:: Xanthomonas hortorum pv. carotae (Xhc) is an epiphytic, plant pathogenic bacterium that causes the disease bacterial blight of carrot (Daucus carota subsp. sativus). Infection with Xhc can result in blighting of leaves and umbels and reduce quality and yield of carrot seed crops. Carrot production in the United States approaches...

Chitinase production of Arthrobacter sp. BN2

Creator:: Miranda-Chavez, Alcibiades Heli
Abstract:: A chitinase producing bacterium was isolated from soil and identified as a species of Arthrobacter. The organism grew well at temperatures between 27 and 33.5 C, and the chitinase production was highest at 25.5 C. As the temperature increased above the optimum point, the level of enzyme production rapidly decreased,...

The SELCTV database : the susceptibility of arthropod natural enemies to agricultural pests to pesticides

Creator:: Theiling, Karen M.
Abstract:: Documentation of the side effects of pesticides on arthropod natural enemies has expanded rapidly since the 1950's as part of an increase in non-target side effects literature. Most reviews have been based on empirical analysis of selected literature. The SELCTV database was developed to make a larger information base accessible...
