Localized extension in megathrust hanging wall following great earthquakes in western Nepal.

The largest (M8+) known earthquakes in the Himalaya have ruptured the upper locked section of the Main Himalayan Thrust zone, offsetting the ground surface along the Main Frontal Thrust at the range front. However, out-of-sequence active structures have received less attention. One of the most impressive examples of such faults is the active fault that generally follows the surface trace of the Main Boundary Thrust (MBT).

Uplift of the Longmen Shan and Tibetan plateau, and the 2008 Wenchuan (M = 7.9) earthquake.

The Longmen Shan mountain range, site of the devastating 12 May 2008 Wenchuan (M = 7.9) earthquake, defines the eastern margin of the Himalayan orogen and exhibits greater topographic relief than anywhere else in the Tibetan plateau. However, before the earthquake, geodetic and geologic surveys measured little shortening across the range front, inspiring a vigorous debate about the process by which the topography of the mountain belt is produced and maintained.

Evaluation of Broccoli Residue Incorporation into Field Soil for Verticillium Wilt Control in Cauliflower.

Wilt incited by Verticillium dahliae has recently become an important disease on cauliflower in the Salinas Valley. Although broccoli is closely related to cauliflower, wilt has not occurred on this host and V. dahliae isolates from cauliflower were weakly pathogenic on broccoli in greenhouse inoculations.

Effects of Chitin and Chitosan on the Incidence and Severity of Fusarium Yellows of Celery.

The effects of chitin and chitosan on disease incidence and severity of Fusarium yellows of celery and on populations of Fusarium oxysporum were investigated between 1994 and 1996. Field experiments were conducted at two locations with a history of severe Fusarium yellows. Disease incidence and severity were significantly reduced by pre-plant chitin amendments to soil.
