2012 Annual Report
1a.Objectives (from AD-416):
The ARS-EBCL will provide research for collection, screening, rearing, and obtain approval for the instruction and release of biological weed control agents for use on BLM administered lands. ARS-EBCL will also provide biological weed control agents to Agricultural Research Service stations in the United States and various Universities for future release of biological weed control agents for the BLM.
1b.Approach (from AD-416):
ARS will collect, identify, and provide initial research to provide biological weed control agents (insects and plant pathogens) for weed species that infest BLM administered lands on leafy spurge, knapweed complex, Russian knapweed, field bindweed, Canada thistle, tamarisk (saltcedar), yellow starthistle, Dyers woad, musk thistle, Scotch thistle, hoary cress, perennial pepperweed, Dalmation and common toadflex. ARS Staff will continue to work with BLM Invasive Species Coordinator and other BLM personnel on Biological weed control efforts.
3. Progress report:
This agreement was established with the Bureau of Land Management to support research on pathogens of medusahead rye grass, an invasive Eurasian weed that impacts U.S. rangelands. Exploration in the native Eurasian range and host range testing research of potential pathogens as candidate agents of medusahead was initiated in conjunction with the EBCL substation in Thessaloniki, Greece, and local Greek university cooperators. Field surveys were conducted in Greece and Turkey. Host range tests include a wide range of related crop and native U.S. and European grass species. Additional details regarding this agreement can be found in the report for the parent project 0212-22000-25-00D, DISCOVERY AND EVALUATION OF CLASSICAL BIOLOGICAL CONTROL AGENTS FOR INVASIVE EURASIAN WEEDS AFFECTING AGRICULTURAL AND NATURAL AREAS.
